Prolonged physical inactivity in young adults may lead to deficiencies in musculoskeletal fitness, and thus a need exists to develop physical activity and exercise programmes that are effective of increasing musculoskeletal fitness. The aim of this study, therefore, was to investigate the effects of small-sided team handball training on lower limb muscle strength, postural balance and body composition in young adults. Twenty-six men and twenty-eight women were stratified for peak oxygen uptake (VO2peak) and body fat percentage and randomly allocated to either 12 wks of small-sided recreational team handball training (THG: 14 men and 14 women, age 24.1±2.6 yrs (mean±SD), VO2peak 39.8±5.9 ml/kg/min and body fat percentage 32.7±8.7%) or serving as non-exercising controls (CON: 12 men and 14 women, age 24.8±3.1 yrs, VO2peak 39.7±5.0 ml/kg/min, body fat percentage 31.7±9.7%). THG trained on average 1.8 times/week for 12 wks. At 0 and 12 wks, lower limb muscle strength, rate of force development (RFD), vertical jump height and power, postural balance, body composition and muscle biopsies were assessed. No training effects were observed for maximal isokinetic or isometric knee extensor strength, maximal vertical jump height or take-off power, fibre type distribution or capillarization. Late phase (RFD) increased (+7.4%, p<0.05) and postural sway excursion length was improved after training (-9%, p<0.05) in THG with no difference from CON (p>0.05). Further, THG demonstrated a decrease in body fat percentage (-3.7%) accompanied by increases in whole-body fat free mass (FFM) (+2.2%), leg FFM (+2.5%), total bone mineral content (BMC) (+1.1%), leg BMC (+1.2%), total hip bone mineral density (+1.6%) and hip T-score (+50%) which differed from CON (all p<0.05). In conclusion, recreational small-sided team handball training appears to effectively improve rapid force capacity, postural balance, lean and fat body mass and bone health in previously untrained young adults. The study was registered at ClinicalTrials.gov (NCT04247724). ClinicalTrials.gov ID number: NCT04247724., Competing Interests: The authors declare that no competing interests exist.

Aims: Current evidence points to cellular anti-ageing effects of regular endurance training which may differ from other sport modalities. Effects of football training on markers of cell senescence have not been tested., Methods: One hundred and forty healthy, non-smoking men participated in the study, including young elite football players aged 18-30 years (YF, n = 35, 21.6 ± 0.5 yrs), elderly football players aged 65-80 years (EF, n = 35, 71.9 ± 0.5 yrs), untrained young controls (YC, n = 35, 24.3 ± 0.6 yrs) and elderly controls (EC, n = 35, 70.1 ± 0.7 yrs). Besides body composition (DXA scan), resting heart rate (RHR), blood pressure (BP) and selected fasting blood variables, mononuclear cells (MNC) were isolated. MNC telomere length was determined by flow-fluorescence in-situ hybridization (FISH) and polymerase chain reaction (PCR). Telomerase activity was quantified using telomerase repeat amplification protocol (TRAP) assay. mRNA expression of anti- and pro-senescent factors was measured with real-time PCR., Results: EF showed 2.5% higher (p = 0.047) granulocyte telomere length and 1.3% higher (p = 0.009) lymphocyte telomere length compared to EC. EF had 37% lower (p = 0.025) mRNA expression of the pro-senescent factor p16 compared to EC. No significant between-group differences (p > 0.050) were observed in telomerase activity or anti-senescent factors (TRF2, Ku70 and POT1a) for EF vs EC. YF had higher telomerase activity (4.2-fold, p = 0.001), telomere repeat binding factor (TRF) 2 mRNA expression (3.2-fold, p = 0.003), Ku70 mRNA expression (2.3-fold, p < 0.001) and POT1a mRNA expression (2.2-fold, p = 0.002) compared to YC, but there was no significant between-group difference in telomere length., Conclusion: This study is the first cross-sectional, controlled trial showing effects of lifelong football participation on telomere shortening and senescence markers in circulating cells, suggesting that football induces cellular anti-senescence mechanisms implying positive long-term cardiovascular health effects., (Copyright © 2020 Elsevier Inc.

Purpose: We tested the hypothesis that participation in small-sided team handball training could provide beneficial effects on cardiovascular and metabolic parameters in overweight premenopausal women with special focus on the importance of prior team handball experience., Methods: A 16-week RCT training intervention was conducted in overweight premenopausal women randomized into three groups: a team handball training group without prior experience (UN; n = 13), a team handball group with prior experience (EXP; n = 10), and an inactive control group (CON; n = 9). Both UN and EXP completed 1.6 ± 0.3 training sessions per week with average heart rates of 84 ± 5 and 85 ± 9% of maximal heart rate, respectively. Cardiovascular and metabolic parameters were assessed before and after the intervention., Results: Compared to CON, UN had significant increases in VO 2max  (7 ± 4%) and intermittent endurance performance (26 ± 14%) as well as reduced total fat mass (4 ± 6%), total fat percentage (4 ± 5%), and android fat mass (7 ± 12%), respectively (all P < .05). Compared to UN and CON, EXP displayed increased left ventricular mass and left ventricular mass index (both P < .05) after the training period. There were no significant changes between any of the groups in muscle mass, blood lipids, resting heart rate, and blood pressure (all P > .05)., Conclusion: Small-sided team handball training in overweight premenopausal women resulted in improvement of VO 2max and body composition for participants with minimal team handball experience, indicating that prior team handball experience is not a prerequisite for improving physiological parameters of importance for health. Furthermore, EXP displayed cardiac adaptations, including increased left ventricular mass and left ventricular mass index., (© 2019 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Purpose: The prevalence of lifestyle diseases has escalated, and effective exercise training programmes are warranted. This study tested the hypothesis that regular participation in small-sided team handball training could provide beneficial health effects on cardiovascular, skeletal, and muscular parameters in young adult untrained men., Method: Twenty-six untrained 20-30-year-old men were randomly allocated to either a team handball training group (HG; n = 14), which completed 1.9 ± 0.3 training sessions per week over 12 weeks, or an inactive control group (CG; n = 12). Physiological training adaptations were assessed pre- and post interventions by DXA scans, blood samples, muscle biopsies, and physical tests., Results: The average heart rate during training was equivalent to 84 ± 4% of maximal heart rate. Compared to CG, HG displayed significant increases in VO 2max (11 ± 6%), proximal femur bone mineral density (2 ± 1%), whole-body bone mineral content (2 ± 1%), intermittent endurance performance (32 ± 16%), incremental treadmill test performance (16 ± 7%) and muscle citrate synthase activity (22 ± 28%) as well as decreases in total fat mass (7 ± 7%) and total fat percentage (6 ± 7%) (all p < 0.05). There were no significant changes in muscle mass, blood pressure, resting heart rate, muscle hydroxyl-acyl-dehydrogenase activity, or blood lipids (all p > 0.05)., Conclusion: Participation in regular recreational team handball training was associated with positive cardiovascular, skeletal, and muscular adaptations, including increased maximal oxygen uptake, increased muscle enzymatic activity, and improved bone mineralization as well as lower fat percentage. These findings suggest that recreational team handball training may be an effective health-promoting activity for young adult men.

Purpose: The purpose of the present controlled cross-sectional study was to investigate proximal femur and whole-body bone mineral density (BMD), as well as bone turnover profile, in lifelong trained elderly male football players and young elite football players compared with untrained age-matched men., Methods: One hundred and forty healthy, non-smoking men participated in the study, including lifelong trained football players (FTE, n  = 35) aged 65-80 years, elite football players (FTY, n  = 35) aged 18-30 years, as well as untrained age-matched elderly (UE, n  = 35) and young (UY, n  = 35) men. All participants underwent a regional dual-energy X-ray Absorptiometry (DXA) scan of the proximal femur and a whole-body DXA scan to determine BMD. From a resting blood sample, the bone turnover markers (BTMs) osteocalcin, carboxy-terminal type-1 collagen crosslinks (CTX-1), procollagen type-1 amino-terminal propeptide (P1NP), and sclerostin were measured., Results: FTE had 7.3%-12.9% higher ( p  <   0.05) BMD of the femoral neck, wards, shaft, and total proximal femur in both legs compared to UE, and 9.3%-9.7% higher ( p  <   0.05) BMD in femoral trochanter in both legs compared to UY. FTY had 24.3%-37.4% higher ( p  <   0.001) BMD in all femoral regions and total proximal femur in both legs compared to UY. The whole-body DXA scan confirmed these results, with FTE showing similar whole-body BMD and 7.9% higher ( p  <   0.05) leg BMD compared to UY, and with FTY having 9.6% higher ( p  <   0.001) whole-body BMD and 18.2% higher ( p  <   0.001) leg BMD compared to UY. The plasma concentration of osteocalcin, CTX-1, and P1NP were 29%, 53%, and 52% higher ( p  <   0.01), respectively, in FTY compared to UY., Conclusion: BMD of the proximal femur and whole-body BMD are markedly higher in lifelong trained male football players aged 65-80 years and young elite football players aged 18-30 years compared to age-matched untrained men. Elderly football players even show higher BMD in femoral trochanter and leg BMD than untrained young despite an age difference of 47 years.

Purpose: The present study evaluated the effects of regular participation in small-sided team handball training on body composition, osteogenic response, physical performance, and cardiovascular risk factors, as well as well-being and motivation, in young untrained women., Methods: Twenty-eight untrained 20- to 30-year-old women were randomized to a handball training group (HG; n  = 14, height 170 ± 5 cm, weight 73 ± 11 kg, VO 2peak 37.7 ± 4.1 mL/min/kg) that trained 1.7 ± 0.3 times per week over 12 weeks (70 min 4 v 4 handball sessions) or an inactive control group (CG; n  = 14, 169 ± 5 cm, 71 ± 12 kg, 38.1 ± 3.7 mL/min/kg). Physiological and psychological and motivational training adaptations were assessed pre- and post-intervention by dual-energy X-ray Absorptiometry (DXA) scans, blood sampling, physical tests, and questionnaires., Results: The average heart rate (HR) over all training sessions was equal to 85% ± 6% HR max . Between-group intervention effects were observed in favor of HG for muscle mass (2.1%, p  = 0.024), proximal femur bone mineral density (0.8%, p  = 0.041), Yo-Yo IE1 intermittent endurance test level 1 (IE1) performance (35%, p  < 0.001), and incremental treadmill test performance (11.5%, p  = 0.003), but not total fat mass ( p  = 0.176), mean arterial blood pressure ( p  = 0.328), resting HR ( p  = 0.219), or blood lipids ( p  = 0.298-0.854). In CG, no changes were observed in any of the measured physiological variables after the training period. Compared to CG, HG had an increase in intrinsic motivation ( p  < 0.001) and in the well-being subscale "energy" ( p  = 0.010)., Conclusion: Participation in regular recreational team handball training organized as small-sided games has marked beneficial effects on physical performance, musculoskeletal fitness, well-being, and motivation in untrained young women.

Unlabelled: Androgen deprivation therapy (ADT) for prostate cancer (PCa) impairs musculoskeletal health. We evaluated the efficacy of 32-week football training on bone mineral density (BMD) and physical functioning in men undergoing ADT for PCa. Football training improved the femoral shaft and total hip BMD and physical functioning parameters compared to control., Introduction: ADT is a mainstay in PCa management. Side effects include decreased bone and muscle strength and increased fracture rates. The purpose of the present study was to evaluate the effects of 32 weeks of football training on BMD, bone turnover markers (BTMs), body composition, and physical functioning in men with PCa undergoing ADT., Methods: Men receiving ADT >6 months (n = 57) were randomly allocated to a football training group (FTG) (n = 29) practising 2-3 times per week for 45-60 min or to a standard care control group (CON) (n = 28) for 32 weeks. Outcomes were total hip, femoral shaft, femoral neck and lumbar spine (L2-L4) BMD and systemic BTMs (procollagen type 1 amino-terminal propeptide, osteocalcin, C-terminal telopeptide of type 1 collagen). Additionally, physical functioning (postural balance, jump height, repeated chair rise, stair climbing) was evaluated., Results: Thirty-two-week follow-up measures were obtained for FTG (n = 21) and for CON (n = 20), respectively. Analysis of mean changes from baseline to 32 weeks showed significant differences between FTG and CON in right (0.015 g/cm(2)) and left (0.017 g/cm(2)) total hip and in right (0.018 g/cm(2)) and left (0.024 g/cm(2)) femoral shaft BMD, jump height (1.7 cm) and stair climbing (-0.21 s) all in favour of FTG (p < 0.05). No other significant between-group differences were observed., Conclusions: Compared to standard care, 32 weeks of football training improved BMD at clinically important femoral sites and parameters of physical functioning in men undergoing ADT for PCa.

Purpose: To investigate the activity profile of football training and its short-term effects on bone mass, bone turnover markers (BTMs) and postural balance in men with prostate cancer (PCa) undergoing androgen deprivation therapy (ADT)., Methods: This was a randomised 12-week study in which men with PCa undergoing ADT were assigned to a football intervention group [FTG, n = 29, 67 ± 7 (±SD) years] training 2‒3 times per week for 45‒60 min or to a control group (n = 28, 66 ± 5 years). The activity profile was measured using a 5-Hz GPS. The outcomes were total body and leg bone mineral content (BMC) and density, BTMs and postural balance., Results: In the last part of the 12 weeks, FTG performed 194 ± 41 accelerations and 296 ± 65 decelerations at >0.6 m/s/s and covered a distance of 905 ± 297 m at speeds >6 km/h and 2646 ± 705 m per training session. Analysis of baseline-to-12-week change scores showed between-group differences in favour of FTG in total body BMC [26.4 g, 95 % confidence interval (CI): 5.8-46.9 g, p = 0.013], leg BMC (13.8 g, 95 % CI: 7.0‒20.5 g, p < 0.001) and markers of bone formation: P1NP (36.6 µg/L, 95 % CI: 10.4‒62.8 µg/L, p = 0.008) and osteocalcin (8.6 µg/L, 95 % CI: 3.3‒13.8 µg/L, p < 0.01). The number of decelerations correlated to the increase in leg BMC (r = 0.65, p = 0.012). No between-group differences were observed for the remaining outcomes., Conclusion: Football training involves numerous runs, accelerations and decelerations, which may be linked to marked increases in bone formation markers and preserved bone mass in middle-aged and elderly men with PCa undergoing ADT., Trial Registration: ClinicalTrials.gov: NCT01711892.

The aim of the study was to determine whether lifelong football training may improve cardiovascular function, physical fitness, and body composition. Our subjects were 17 male veteran football players (VPG; 68.1 ± 2.1 years) and 26 healthy age-matched untrained men who served as a control group (CG; 68.2 ± 3.2 years). Examinations included measurements of cardiac function, microvascular endothelial function [reactive hyperemic index (RHI)], maximum oxygen uptake (VO2max), and body composition. In VPG, left ventricular (LV) end-diastolic volume was 20% larger (P < 0.01) and LV ejection fraction was higher (P < 0.001). Tissue Doppler imaging revealed an augmented LV longitudinal displacement, i.e., LV shortening of 21% (P < 0.001) and longitudinal 2D strain was 12% higher (P < 0.05), in VPG. In VPG, resting heart rate was lower (6 bpm, P < 0.05), and VO2max was higher (18%, P < 0.05). In addition, RHI was 21% higher (P < 0.05) in VPG. VPG also had lower body mass index (P < 0.05), body fat percentage, total body fat mass, android fat percentage, and gynoid fat percentage (all P < 0.01). Lifelong participation in football training is associated with better LV systolic function, physical fitness, microvascular function, and a healthier body composition. Overall, VPG have better cardiovascular function compared with CG, which may reduce their cardiovascular morbidity and mortality., (© 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

This case-control study investigated the feasibility of street football as a health-enhancing activity for homeless men, specifically the musculoskeletal effects of 12 weeks of training. Twenty-two homeless men participated in the football group (FG) and 10 served as controls (C). Plasma osteocalcin, TRACP5b, leptin, and postural balance were measured, and whole-body DXA scanning was performed. The attendance rate was 75% (2.2 ± 0.7 sessions per week). During 60 min of training, the total distance covered was 5534 ± 610 m, with 1040 ± 353, 2744 ± 671, and 864 ± 224 m covered by high-intensity, low-intensity, and backwards/sideways running, respectively. In FG, osteocalcin increased by 27% from 20.1 ± 11.1 to 25.6 ± 11.8 ng/mL (P = 0.007). Postural balance increased by 39% (P = 0.004) and 46% (P = 0.006) in right and left leg. Trunk bone mineral density increased by 1.0% from 0.959 ± 0.095 to 0.969 ± 0.090 g/cm(2) (P = 0.02). No effects were observed in C. In conclusion, street football appears to be a feasible training activity with musculoskeletal health benefits for homeless men. The attendance rate and the training intensity were high, and 12 weeks of training resulted in a substantial anabolic response in bone metabolism. Postural balance improved markedly, and the overall risk of falling, and hospitalization due to sudden trauma, could be reduced by street football for homeless men., (© 2014 John Wiley & Sons A/S.

The effects of regular football training on glycemic control, body composition, and peak oxygen uptake (VO₂ peak) were investigated in men with type 2 diabetes mellitus (T2DM). Twenty-one middle-aged men (49.8 ± 1.7 years ± SEM) with T2DM were divided into a football training group (FG; n = 12) and an inactive control group (CG; n = 9) during a 24-week intervention period (IP). During a 1-h football training session, the distance covered was 4.7 ± 0.2 km, mean heart rate (HR) was 83 ± 2% of HRmax, and blood lactate levels increased (P < 0.001) from 2.1 ± 0.3 to 8.2 ± 1.3 mmol/L. In FG, VO₂ peak was 11% higher (P < 0.01), and total fat mass and android fat mass were 1.7 kg and 12.8% lower (P < 0.001), respectively, after IP. After IP, the reduction in plasma glucose was greater (P = 0.02) in FG than the increase in CG, and in FG, GLUT-4 tended to be higher (P = 0.072) after IP. For glycosylated hemoglobin (HbA1), an overall time effect (P < 0.01) was detected after 24 weeks. After IP, the number of capillaries around type I fibers was 7% higher (P < 0.05) in FG and 5% lower (P < 0.05) in CG. Thus, in men with T2DM, regular football training improves VO₂ peak, reduces fat mass, and may positively influence glycemic control., (© 2014 John Wiley & Sons A/S.

Androgen deprivation therapy (ADT) remains a cornerstone in the management of patients with prostate cancer (PCa) despite adverse effects on body composition and functional parameters. We compared the effects of football training with standard care in PCa patients managed with ADT (> 6 months). Fifty-seven men aged 67 (range: 43-74) were randomly assigned to a football group (FG, n = 29) or a usual care control group (CON, n = 28). The primary outcome was change in lean body mass (LBM) assessed by dual-energy X-ray absorptiometry scanning. Secondary outcomes included changes in knee-extensor muscle strength (one repetition maximum), fat percentage, and maximal oxygen uptake (VO2max ). Mean heart rate during training was 137.7 (standard deviation 13.7) bpm or 84.6 (3.9)% HRmax. In FG, LBM increased by 0.5 kg [95% confidence interval (CI) 0.1-0.9; P = 0.02] with no change in CON (mean group difference 0.7 kg; 95% CI 0.1-1.2; P = 0.02). Also, muscle strength increased in FG (8.9 kg; 95% CI 6.0-11.8; P < 0.001) with no change in CON (mean group difference 6.7 kg; 95% CI 2.8-10.7; P < 0.001). In FG, VO2max increased (1.0 mL/kg/min; 95% CI 0.2-1.9; P = 0.02) and fat percentage tended to decrease (0.7%; 95%CI 1.3-0.0; P = 0.06), but these changes were not significantly different from CON. In conclusion, football training over 12 weeks improved LBM and muscle strength compared with usual care in men with prostate cancer receiving ADT., (© 2014 John Wiley & Sons A/S.

We investigated the effects of 3 and 6 months of regular football training on cardiac structure and function in hypertensive men. Thirty-one untrained males with mild-to-moderate hypertension were randomized 2:1 to a football training group (n = 20) and a control group receiving traditional recommendations on healthy lifestyle (n = 11). Cardiac measures were evaluated by echocardiography. The football group exhibited significant (P < 0.05) changes in cardiac dimensions and function after just 3 months: Left ventricular (LV) end-diastolic volume increased from 104 ± 25 to 117 ± 29 mL. LV diastolic function improved measured as E/A ratio (1.15 ± 0.32 to 1.54 ± 0.38), early diastolic velocity, E' (11.0 ± 2.5 to 11.9 ± 2.6 cm/s), and isovolumetric relaxation time (74 ± 13 to 62 ± 13 ms). LV systolic function improved measured as longitudinal displacement (10.7 ± 2.1 to 12.1 ± 2.3 mm). Right ventricular function improved with respect to tricuspid annular plane systolic excursion (21.8 ± 3.2 to 24.5 ± 3.7 mm). Arterial blood pressure decreased in both groups, but significantly more in the football training group. No significant changes were observed in the control group. In conclusion, short-term football training improves LV diastolic function in untrained men with mild-to-moderate arterial hypertension. Furthermore, it may improve longitudinal systolic function of both ventricles. The results suggest that football training has favorable effects on cardiac function in hypertensive men., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

This study examined the effect of recreational football and resistance training on bone mineral density (BMD) and bone turnover markers (BTMs) in elderly men. Twenty-six healthy sedentary men (age 68.2 ± 3.2 years) were randomized into three groups: football (F; n = 9) and resistance training (R; n = 9), completing 45-60 min training two to three times weekly, and inactive controls (C; n = 8). Before, after 4 months, and after 12 months, BMD in proximal femur (PF) and whole body (WB) were determined together with plasma osteocalcin (OC), procollagen type-1 amino-terminal propeptide (P1NP), and carboxy-terminal type-1 collagen crosslinks (CTX-1). In F, BMD in PF increased up to 1.8% (P < 0.05) from 0 to 4 months and up to 5.4% (P < 0.001) from 0 to 12 months; WB-BMD remained unchanged. After 4 and 12 months of football, OC was 45% and 46% higher (P < 0.001), and P1NP was 41% and 40% higher (P < 0.001) than at baseline, respectively. After 12 months, CTX-1 showed a main effect of 43% (P < 0.05). In R and C, BMD and BTM remained unchanged. In conclusion, 4 months of recreational football for elderly men had an osteogenic effect, which was further developed after 12 months, whereas resistance training had no effect. The anabolic response may be due to increased bone turnover, especially improved bone formation., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

The study examined the effects of 1 year of football or strength training on cardiovascular function in 65- to 75-year-old men. Twenty-six untrained men (age: 68.2 ± 3.2 years) were randomized to football training (FTG; n = 9), strength training (STG; n = 9), or control (CG; n = 8). In FTG, left ventricular (LV) internal diastolic diameter, end-diastolic volume, and mass index were 8%, 21%, and 18% higher (P < 0.01), respectively, after 12 months, with no changes in STG and CG. After 12 months, LV ejection fraction was increased (P < 0.05) by 8% and 5% in FTG and STG, respectively, and systolic longitudinal two-dimensional strain by 8% and 6%, whereas right ventricular systolic function improved (P < 0.05) by 22% in FTG, but not in STG and CG. In FTG, LV diastolic mitral inflow (E/A) ratio and peak early diastolic velocity (E') improved (P < 0.05) by 25% and 12%, respectively, after 12 months, with no changes in STG and CG. In FTG, maximum oxygen uptake was 16% and 18% higher (P < 0.001) after 4 and 12 months, respectively, and resting heart rate was 6 and 8 beats per minute lower (P < 0.001), respectively, with no changes in STG and CG. In conclusion, football training elicited superior cardiovascular effects compared with strength training in elderly untrained men., (© 2014 John Wiley & Sons A/S.

Evidence is accumulating that exercise-based rehabilitation improves physical capacity and quality of life in cancer survivors. However, recruitment and persistence of male cancer patients in rehabilitation and physical activity are low and novel health promotion strategies are warranted. The purpose of this study was to gain an understanding of the meaning of recreational football as a team and interaction-oriented health-promoting activity in men with prostate cancer (n = 26). Qualitative data were collected through six focus group interviews (n = 4-6) and 20 h of participant observations. The two data sets were analyzed using framework analysis. The analysis produced 11 subthemes that were structured into three overarching themes: (a) motivational drivers; (b) united in sport; and (c) confirmation of own capacity. The findings indicated that participants regarded football as a welcome opportunity to regain control and acquire a sense of responsibility for own health without assuming the patient role, and football training legitimized and promoted mutual caring behavior in a male-oriented context. In conclusion, the study suggests that football, due to its cultural representation of masculine ideals, may be a potent and unique strategy for increasing recruitment and adherence to physical activity in prostate cancer patients., (© 2014 John Wiley & Sons A/S.

The present study investigated the heart rate (HR) response to various types of physical education (PE) activities for 8- to 9-year-olds (five school classes, n = 93) and the fitness effects of a short-term PE training programme (three of the five classes, n = 59) with high compared to low-to-moderate aerobic intensity. HR was recorded during small-sided indoor soccer (SO), basketball (BB), unihockey (UH), circuit training (CT), walking (W) and Nintendo Wii Boxing (NWB) and Nintendo Wii Tennis (NWT). Maximal HR (HRmax) and physical fitness was determined by the Yo-Yo Intermittent Recovery Level 1 Children's test (YYIR1C) test. Following cluster randomisation, three classes were tested before and after 6 wks with 2 × 30 min/wk SO and UH lessons [high-intensity (HI), 2 classes, n = 39] or low-to-moderate intensity PE lessons (CON, 1 class, n = 20). Average HR in SO (76 ± 1% HRmax), BA (77 ± 1% HRmax) and UH (74 ± 1% HRmax) was higher (P < 0.05) than in CT (62 ± 1% HRmax), W (57 ± 1% HRmax), NWB (65 ± 2% HRmax) and NWT (57 ± 1% HRmax). Time with HR > 80% and 90% HRmax, respectively, was higher (P < 0.05) in SO (42 ± 4 and 12 ± 2%), BB (41 ± 5 and 13 ± 3%) and UH (34 ± 3 and 9 ± 2%) than in CT, W and NW (0-5%), with time >80% HRmax being higher (P < 0.05) in SO than UH. After 6 wk, YYIR1C performance was increased (P < 0.05) by 22% in HI (673 ± 57 to 821 ± 71 m), but unaltered in CON (674 ± 88 to 568 ± 81 m). HR 2 min into YYIR1C was lowered (P < 0.05) in HI after 6 wks (92.4 ± 0.8 to 89.1 ± 0.9% HRmax), but not in CON. In conclusion, ball games elicited high aerobic loading for young schoolchildren and a short-term, low-volume ball game PE-intervention improved physical fitness. Traditional PE sessions had no effects on intermittent exercise performance.

Background: Androgen deprivation therapy (ADT) is a cornerstone in the treatment of advanced prostate cancer. Adverse musculoskeletal and cardiovascular effects of ADT are widely reported and investigations into the potential of exercise to ameliorate the effects of treatment are warranted. The 'Football Club (FC) Prostate' study is a randomized trial comparing the effects of soccer training with standard treatment approaches on body composition, cardiovascular function, physical function parameters, glucose tolerance, bone health, and patient-reported outcomes in men undergoing ADT for prostate cancer., Methods/design: Using a single-center randomized controlled design, 80 men with histologically confirmed locally advanced or disseminated prostate cancer undergoing ADT for 6 months or more at The Copenhagen University Hospital will be enrolled on this trial. After baseline assessments eligible participants will be randomly assigned to a soccer training group or a control group receiving usual care. The soccer intervention will consist of 12 weeks of training 2-3 times/week for 45-60 min after which the assessment protocol will be repeated. Soccer training will then continue bi-weekly for an additional 20 weeks at the end of which all measures will be repeated to allow for additional analyses of long-term effects. The primary endpoint is changes in lean body mass from baseline to 12 weeks assessed by dual X-ray absorptiometry scan. Secondary endpoints include changes of cardiovascular, metabolic, and physical function parameters, as well as markers of bone metabolism and patient-reported outcomes., Discussion: The FC Prostate trial will assess the safety and efficacy of a novel soccer-training approach to cancer rehabilitation on a number of clinically important health outcomes in men with advanced prostate cancer during ADT. The results may pave the way for innovative, community-based interventions in the approach to treating prostate cancer., Trial Registration: ClinicalTrials.gov: NCT01711892.

We examined effects of a 3-month football training programme in overweight children using comprehensive echocardiography and peripheral arterial tonometry. Twenty preadolescent overweight children (17 boys, 3 girls aged 8-12 yrs; body mass index [BMI] ≥ 85(th) percentile) participated in a structured 3-month football training programme, consisting of 4 weekly 60-90 min sessions with mean heart rate (HR) > 80% of HRmax (football group, FG). A parallel control group (CG) included 11 children (7 boys, 4 girls) of equivalent age from an obesity clinic. After 3 months, systolic blood pressure was unchanged in FG, but had increased in CG (112 [s 6] vs. 122 [10] mmHg, P = 0.02). FG demonstrated increased left ventricular (LV) posterior wall diameter (0.60 [0.07] vs. 0.68 [0.10] cm, P < 0.001) and an improved right ventricular systolic function determined by tricuspid annular plane systolic excursion (TAPSE, 2.01 [0.29] vs. 2.27 [0.28] cm, P = 0.003). Measures of LV systolic function showed only discrete alterations and two-dimensional (2D) global strain was not changed. After 3 months, global isovolumetric relaxation time (IVRTglobal) had increased in FG (64.0 [7.5] vs. 73.9 [9.4] ms, P < 0.001) while other examined LV diastolic function variables were not altered. No echocardiographic changes were observed in CG. Between-group differences in pre-post delta values were observed for systolic blood pressure, TAPSE, and IVRTglobal (P = 0.02-0.03). We conclude that short-term football training may have positive structural and functional effects on the cardiovascular system in overweight preadolescent children.

This study examined the effect of 12 weeks of small-sided street soccer (2.2 ± 0.7 sessions/week) and fitness center training (0.5 ± 0.2 sessions/week) on physical fitness and cardiovascular health profile for homeless men. Exercise capacity, maximal oxygen uptake (VO(2max)), body composition (DXA scans), blood pressure (BP), and blood lipid profile were determined before and after the intervention period for 22 soccer-group subjects (SG) and 10 waiting list controls (CO). In addition, time-motion analyses, HR measurements, and pedometer recordings were performed during street soccer training and daily-life activities. During a 60 min 4 versus 4 street soccer session 182 ± 62 intense running bouts were performed; mean HR was 82 ± 4% HR(max) and HR was >90% HR(max) for 21 ± 12% (±SD) of total time. On a day without training the participants performed 10,733 ± 4,341 steps and HR was >80% HR(max) for 2.4 ± 4.3 min. In SG, VO(2max) was elevated (p < 0.05) from 36.7 ± 7.6 to 40.6 ± 8.6 ml/min/kg after 12 weeks and incremental cycle test performance was improved (p < 0.05) by 81 s (95% CI: 47-128 s). After 12 weeks, fat percentage (19.4 ± 8.5 to 17.5 ± 8.6%) and LDL cholesterol (3.2 ± 1.1 to 2.8 ± 0.8 mmol L(-1)) were lowered (p < 0.05) in SG. The observed changes in SG were different (p < 0.05) from CO and no intra-group changes occurred for CO (p > 0.05). BP was unaltered after 12 weeks (p > 0.05), but diastolic BP was lowered for all SG subjects with pre-values >75 mmHg (83 ± 6 to 76 ± 6 mmHg, n = 8, p < 0.05). In conclusion, the exercise intensity is high during street soccer and regular street soccer training can be used as an effective activity to promote physical fitness and cardiovascular health status for homeless men.

Purpose: The purpose of this study was to determine the effectiveness of brief intense interval training as exercise intervention for promoting health and to evaluate potential benefits about common interventions, that is, prolonged exercise and strength training., Methods: Thirty-six untrained men were divided into groups that completed 12 wk of intense interval running (INT; total training time 40 min wk(-1)), prolonged running (approximately 150 min wk(-1)), and strength training (approximately 150 min wk(-1)) or continued their habitual lifestyle without participation in physical training., Results: The improvement in cardiorespiratory fitness was superior in the INT (14% +/- 2% increase in V˙O2max) compared with the other two exercise interventions (7% +/- 2% and 3% +/- 2% increases). The blood glucose concentration 2 h after oral ingestion of 75 g of glucose was lowered to a similar extent after training in the INT (from 6.1 +/- 0.6 to 5.1 +/- 0.4 mM, P < 0.05) and the prolonged running group (from 5.6 +/- 1.5 to 4.9 +/- 1.1 mM, P < 0.05). In contrast, INT was less efficient than prolonged running for lowering the subjects' resting HR, fat percentage, and reducing the ratio between total and HDL plasma cholesterol. Furthermore, total bone mass and lean body mass remained unchanged in the INT group, whereas both these parameters were increased by the strength-training intervention., Conclusions: INT for 12 wk is an effective training stimulus for improvement of cardiorespiratory fitness and glucose tolerance, but in relation to the treatment of hyperlipidemia and obesity, it is less effective than prolonged training. Furthermore and in contrast to strength training, 12 wk of INT had no impact on muscle mass or indices of skeletal health.

Objectives: The aim of this study was to describe trends in the management of pregnancies in HIV-infected women and their outcomes over a 14-year period in Denmark on a national basis., Methods: The study was a retrospective cohort study of all HIV-infected women in Denmark giving birth to one or more children between 1 June 1994 and 30 June 2008., Results: We identified 210 HIV-infected women with 255 pregnancies, ranging from 7 per year in 1995 to 39 per year in 2006. Thirty per cent of the women were Caucasian and 51% were Black African. Knowledge of HIV status before pregnancy increased from 8% (four of 49) in 1994-1999 to 80% (164 of 206) in 2000-2008. Only 29% (53 of 183) of the women chose to consult an infectious disease specialist when planning pregnancy, while 14% (27 of 199) received assistance with fertility. The proportion of women on antiretroviral therapy (ART) increased from 76% (37 of 49) in 1994-1999 to 98% (201 of 206) in 2000-2008. Vaginal deliveries ranged from 0 in 2003 to 35% of pregnancies in 2007. Mother-to-child transmission (MTCT) of HIV decreased from 10.4% in 1994-1999 to 0.5% in 2000-2008. All women giving birth to an HIV-positive child were diagnosed with HIV during or after delivery and did not receive prophylactic ART., Conclusions: The annual number of HIV pregnancies increased fivefold during this 14-year period and substantial changes in pregnancy management were seen. No woman treated according to the national guidelines, i.e. ART before week 22, intravenous zidovudine (ZDV) during labour, neonatal ZDV for 4 to 6 weeks and no breastfeeding, transmitted HIV to her child.
