Objective: The aim of this study was to describe posttreatment cancer survivors' lived experience of long-term maintenance of physical activity (PA).Methods: A qualitative, salutogenetic-oriented study was conducted based on four audiotaped, semistructured focus group interviews. Interviewee selection was carried out through purposeful sampling. Twenty-three cancer survivors (17 women and 6 men; median age 50 years, range 29-70) who were physically inactive prior to their diagnosis but who had been exercising regularly for a minimum of 18 months posttreatment participated in the study. The participants were recruited from The Copenhagen PACT Study that evaluated the effect of a one-year rehabilitation program (supervised exercise [weekly], expert lectures [trimonthly], in-group coaching [bimonthly] and individual coaching [3 × 1 h]). Data were analyzed by use of systematic condensation analysis inspired by Giorgi's descriptive phenomenological methodology (see Sketch of a psychological phenomenological method, in: Giorgi A (ed.), Phenomenology and Psychological Research, Duquesne University Press, Pittsburgh, 1985).Results: The analysis revealed five categories, which were summarized into an overall sentence describing the essence of long-term PA maintenance in cancer survivors: demonstration and manifestation of self-determination and illness resistance. In sum, the participants described regular PA as a prerequisite for feeling and staying well and preserving and pursuing own potentials whereby PA maintenance becomes a goal in itself.Conclusions: This study indicates that cancer survivors' continued motivation for PA may be dependent on the fulfillment of a personal and conscious experience of being in the process of creating and living a comprehensible and meaningful life. Future theory-based interventions to encourage PA maintenance in cancer survivors could potentially benefit by integration of humanistic and existential psychology in addition to social cognitive theory and theory of planned behavior.

Purpose: To examine efficacy of 12 months Football Fitness offered twice per week on bone mineral density (BMD), bone turnover markers (BTM), postural balance, muscle strength, and body composition in women treated for early-stage breast cancer (BC)., Methods: Women treated for early-stage BC were randomized to Football Fitness (FFG, n = 46) or control (CON, n = 22) in a 2:1 ratio for 12 months, with assessments performed at baseline, 6 months and 12 months. Outcomes were total body-, lumbar spine- and proximal femur BMD, total body lean and fat mass, leg muscle strength, postural balance, and plasma amino-terminal propeptide of type 1 procollagen (P1NP), osteocalcin, and C-terminal telopeptide of type 1 collagen (CTX). Intention-to-treat (ITT) analyses and per-protocol analyses (≥50% attendance in FFG) were performed using linear mixed models., Results: Participants in FFG completing the 12-month intervention (n = 33) attended 0.8 (SD = 0.4) sessions per week. Intention to treat analysis of mean changes over 12 months showed significant differences (p<.05) in L1-L4 BMD (0.029 g/cm 2 , 95%CI: 0.001 to 0.057), leg press strength (7.2 kg, 95%CI: 0.1 to 14.3), and postural balance (-4.3 n need of support, 95%CI: -8.0 to -0.7) favoring FFG compared to CON. In the per-protocol analyses, L1-L4 and trochanter major BMD were improved (p = .012 and .030, respectively) in FFG compared with CON. No differences were observed between groups in BTMs in the ITT or per protocol analyses., Conclusion: One year of Football Fitness training may improve L1-L4 BMD, leg muscle strength, and postural balance in women treated for early-stage breast cancer., (© 2021 John Wiley & Sons A/S.

Background: Breast cancer survivors are encouraged to be physically active. A recent review suggests that football training is an effective exercise modality for women across the lifespan, positively influencing health variables such as strength, fitness and social well-being. However, football is a contact sport, potentially posing an increased risk of trauma-related injury. Against this backdrop, breast cancer survivors are advised to avoid trauma or injury to the affected or at-risk arm in order to protect against lymphedema onset or exacerbation. The aim of this study was therefore to evaluate the feasibility and safety of Football Fitness training in relation to lymphedema and upper-extremity function after treatment for breast cancer., Material and Methods: Sixty-eight women aged 18-75 years, who had received surgery for stage I-III breast cancer and completed (neo) adjuvant chemotherapy and/or radiotherapy within five years, were randomized (2:1) to a Football Fitness group (FFG, n  = 46) or a control group (CON, n  = 22) for twelve months. Secondary analyses using linear mixed models were performed to assess changes in upper-body morbidity, specifically arm lymphedema (inter-arm volume % difference, dual energy X-ray absorptiometry; extracellular fluid (L-Dex), bioimpedance spectroscopy), self-reported breast and arm symptoms (EORTC breast cancer-specific questionnaire (BR23) and upper-extremity function (DASH questionnaire) at baseline, six- and twelve-month follow-up., Results: We observed similar point prevalent cases of lymphedema between groups at all time points, irrespective of measurement method. At the six-month post-baseline assessment, reductions in L-Dex (extracellular fluid) were found in FFG versus CON. These significant findings were not maintained at the twelve-month assessment. No difference between groups was observed for inter-limb volume difference %, nor any of the remaining outcomes., Conclusion: While superiority of Football Fitness was not observed, the results support that participation in Football Fitness training is feasible and suggests no negative effects on breast cancer-specific upper-body morbidity, including lymphedema., Trial Registration: The trial was registered at ClinicalTrials.gov. NCT03284567.

Purpose: To examine the exercise intensity and impact of 12 months of twice-weekly recreational football training on cardiorespiratory fitness (CRF), blood pressure (BP), resting heart rate (HR rest ), body fat mass, blood lipids, inflammation, and health-related quality of life in women treated for early-stage breast cancer (BC)., Methods: Sixty-eight women who had received surgery for stage I-III BC and completed adjuvant chemo- and/or radiation therapy within 5 years were randomized in a 2:1 ratio to a Football Fitness group (FFG, n = 46) or a control group (CON, n = 22). Football Fitness sessions comprised a warm-up, drills and 3-4 × 7 min of small-sided games (SSG). Assessments were performed at baseline, 6 months and 12 months. Outcomes were peak oxygen uptake (VO 2 peak), blood pressure (BP), HR rest , total body fat mass, and circulating plasma lipids and hs-CRP, and the 36-Item Short Form Health Survey (SF36). Intention-to-treat (ITT) analyses were performed using linear mixed models. Data are means with SD or 95% confidence intervals., Results: Adherence to training in participants completing the 12-months follow-up (n = 33) was 47.1% (22.7), and HR during SSG was ≥80% of HR max for 69.8% (26.5) of total playing time. At baseline, VO 2 peak was 28.5 (6.4) and 25.6 (5.9) ml O 2 /kg/min in FFG and CON, respectively, and no significant changes were observed at 6- or 12 months follow-up. Systolic BP (SBP) was 117.1 (16.4) and 116.9 (14.8) mmHg, and diastolic BP (DBP) was 72.0 (11.2) and 72.4 (8.5) mmHg in FFG and CON, respectively, at baseline, and a 9.4 mmHg decrease in SBP in CON at 12 months resulted in a between-group difference at 12 months of 8.7 mmHg (p = .012). Blood lipids and hs-CRP were within the normal range at baseline, and there were no differences in changes between groups over the 12 months. Similarly, no differences between groups were observed in HR rest and body fat mass at 6- and12-months follow-up. A between-group difference in mean changes of 23.5 (0.95-46.11) points in the role-physical domain of the SF36 survey favored FFG at 6 months., Conclusion: Football Fitness training is an intense exercise form for women treated for breast cancer, and self-perceived health-related limitations on daily activities were improved after 6 months. However, 1 year of Football Fitness training comprising 1 weekly training session on average did not improve CRF, BP, blood lipids, fat mass, or HR rest ., Trial Registration Number: The trial was registered at ClinicalTrials.gov with identifier NCT03284567., Competing Interests: Declaration of competing interest None., (Copyright © 2020 Elsevier Inc.

The incidence of cancer in adults aged 60 years and older is expected to rise, and because cancer is associated with aging, the overall prevalence of cancer will rise as well. With advances in cancer treatment, more older adults will receive treatment but they will also suffer the biopsychosocial consequences of cancer and cancer treatment. In this review, we describe the importance of assessing biopsychosocial needs in this vulnerable population and highlight studies supporting the use of exercise in addressing these needs. We discuss challenges and research gaps in several areas including 1) Identifying the exercise doses and modes for specific outcomes, 2) Understanding risks and safety of exercise, and 3) Implementing exercise programs into clinical practice at the individual, health care team, and organizational levels, including strategies to increase adherence., (Copyright © 2018 Elsevier Inc.

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.

Introduction: Recent studies have shown that vitamin-D intake can improve skeletal muscle function and strength in frail vitamin-D insufficient individuals. We investigated whether vitamin-D intake can improve the muscular response to resistance training in healthy young and elderly individuals, respectively., Methods: Healthy untrained young (n = 20, age 20-30) and elderly (n = 20, age 60-75) men were randomized to 16 weeks of daily supplementary intake of either 48 μg of vitamin-D + 800 mg calcium (Vitamin-D-group) or 800 mg calcium (Placebo-group) during a period and at a latitude of low sunlight (December-April, 56°N). During the last 12 weeks of the supplementation the subjects underwent progressive resistance training of the quadriceps muscle. Muscle hypertrophy, measured as changes in cross sectional area (CSA), and isometric strength of the quadriceps were determined. Muscle biopsies were analyzed for fiber type morphology changes and mRNA expression of vitamin-D receptor (VDR), cytochrome p450 27B1 (CYP27B1) and Myostatin., Results: In the vitamin-D groups, serum 25(OH)D concentration increased significantly and at week 12 was significantly different from placebo in both young men (71.6 vs. 50.4 nmol/L, respectively) and elderly men (111.2 vs. 66.7 nmol/L, respectively). After 12 weeks of resistance training, quadriceps CSA and isometric strength increased compared to baseline in young (CSA p < 0.0001, strength p = 0.005) and elderly (CSA p = 0.001, strength p < 0.0001) with no difference between vitamin-D and placebo groups. Vitamin-D intake and resistance training increased strength/CSA in elderly compared to young (p = 0.008). In the young vitamin-D group, the change in fiber type IIa percentage was greater after 12 weeks training (p = 0.030) and Myostatin mRNA expression lower compared to the placebo group (p = 0.006). Neither resistance training nor vitamin-D intake changed VDR mRNA expression., Conclusion: No additive effect of vitamin-D intake during 12 weeks of resistance training could be detected on either whole muscle hypertrophy or muscle strength, but improved muscle quality in elderly and fiber type morphology in young were observed, indicating an effect of vitamin-D on skeletal muscle remodeling., Trial Registration: ClinicalTrials with nr. NCT01252381.

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.

Biosynthesis of the hypericins that accumulate in the dark glands of some members of the genus Hypericum is poorly understood. The gene named hyp-1, isolated from Hypericum perforatum L. has been proposed as playing an important role in the final steps of hypericin biosynthesis. To study the role of this candidate gene in relation to the production of hypericins, the expression of this gene was studied in 15 Hypericum species with varying ability to synthesise hypericin. While the accumulation of hypericins and emodin, an intermediate in the respective pathway, was associated with the dark glands in the hypericin-producing species, the hyp-1 gene was expressed in all studied species regardless of whether hypericins and emodin were detected in the plants. The coding sequences of hyp-1 cDNA were isolated from all species and showed more than 86% similarity to each other. Although, in general, an increased level of the hyp-1 gene transcript was detected in hypericin-producing species, several of the hypericin-lacking species expressed comparable levels as well. Our results question the role of the hyp-1 gene product as a key enzyme responsible for biosynthesis of hypericins in the genus Hypericum. The function of the hyp-1 gene may not be restricted to hypericin biosynthesis only, or some additional factors are necessary for completion of hypericin biosynthesis.
