Studies show aerobic exercise increases irisin and leads to health benefits. The impact of circuit training (CT) on irisin in overweight younger and older adults is unknown. The objectives were to determine whether, during an acute bout of CT, changes in irisin differed between overweight younger and older adults, and if irisin is associated with body composition, fitness level, or muscle strength. Inactive, overweight adults aged between 19–35 (25.9 ± 5.0; n = 15) and 60–75 years (67.7 ± 4.1; n = 14) participated in this study. The primary exposure variable was an acute bout of CT (12–15 repetitions; 65–70% of 1-repetition maximum; 3 loops). The primary outcome measure was the concentration of irisin determined by ELISA before, during, and after exercise. Repeated-measures analyses showed no effect of time on irisin levels during acute CT, and no interaction effect between age and time (p > 0.05). No associations were observed between changes in irisin and body composition, fitness, or strength (p > 0.05). In conclusion, acute CT does not increase irisin in overweight individuals, and irisin is not associated with the measured outcomes. Further studies are needed to elucidate the release of irisin by different types of exercise across the lifespan. This trial was registered at clinicaltrials.gov (NCT03715088). Novelty: Younger and older adults show a similar irisin response to an acute bout of circuit training. Irisin response is not associated with measures of body composition, cardiorespiratory fitness, or muscle strength.

Objectives: The aim of this study was to compare the efficacy of home-based upper extremity circuit training exercises (CTEs) with supervised hospital program in male patients with traumatic complete paraplegia. Patients and methods: Twenty men with paraplegia (mean age: 38±10.1 years; range, 30 to 43 years) between January 2007 and November 2007 were randomized into two groups. The first group had supervised hospital CTE program, whereas the second group had home-based CTE. The effects of the upper extremity CTE by using elastic bands 60 min per day, five days a week, for a total of eight weeks (70% maximal oxygen consumption [VO2max]) were examined. The Cybex was used for the isokinetic testing of the upper extremities. The VO2max and maximum heart rate (HR) were assessed using an arm ergometer. The Craig Handicap Report Technique Short Form (CHART-SF) was used for the evaluation of functional independence and mobility. Serum lipid profiles were measured. Results: The mean injury duration was 7.9±2 years. The peak torque values of the upper extremities, VO2max, maximum HR, CHART-SF physical independence and mobility scores, and serum lipid profile were all improved in both groups (p0.05). The improvement in the VO2max, physical independence, and mobility scores were greater in the supervised exercise group. Conclusion: Upper extremity strength, cardiovascular endurance, and lipid profile were improved after supervised and home-based CTE in the men with paraplegia. Home-based exercise programs may be good alternatives to the hospital rehabilitation for this patient population.

Sustainable exercise strategies are needed for older adults to maintain aerobic capacity and strength. The objective of this pilot in 6 adults ≥ 65 years of age was to determine the feasibility and preliminary efficacy of high-intensity functional circuit training which does not require stationary equipment. Instructor-led small group exercise classes were held 3x/week for 12 weeks using weight-bearing exercises performed in a circuit format at ratings of perceived exertion (RPE) of 6-8/10. All 6 participants completed the pilot and showed significant improvements by the Wilcoxon signed-rank test. The six-minute walk distance increased 10.5%. Timed arm curl and chair stands increased 26.8% and 30.3% (all p ≤ 0.03). These preliminary findings suggest that high-intensity functional circuit exercise is feasible in older adults and increases functional measures of aerobic capacity and strength. Further research is warranted to develop this strategy which has the potential for broad dissemination without the need for a traditional exercise facility.

Brewer, CB, Booher, BM, and Lawton, N. Comparison of acute energy expenditure and rating of perceived exertion in equivalent bouts of circuit training and treadmill running. J Strength Cond Res 35(3): 680-687, 2021-Circuit weight training (CT) maximizes exercise density, which may lead to an inaccurate perception of energy expenditure (EE). The purpose of this study was to compare acute EE indices and rating of perceived exertion (RPE) between CT and an equivalent bout of treadmill running (TR). College-aged men (n = 9) who regularly engaged in running and resistance training performed CT first. Circuit weight training that consisted of 10 resistance stations (40% of 1 repetition maximum, 15 repetitions, 60 b·min-1) was performed for 20 minutes. Heart rate (HR) and EE (Cosmed K4b2) were monitored continuously, and RPE was assessed consistently. A 20-min TR session was performed at the average HR maintained during CT. Dependent t-tests were used to assess differences in RPE, total EE (TEE, kcal), rate of EE (REE, kcal·min-1), and relative REE (RREE, kcal·kg-1·min-1) between CT and TR. Pearson's correlation was used to examine relationships between RPE and EE indices. Total EE was lower during CT (168.19 ± 16.42) than TR (244.20 ± 44.80); REE was lower during CT (8.49 ± 0.90) than TR (12.21 ± 2.24); and RREE was lower during CT (0.10 ± 0.02) than TR (0.15 ± 0.02) (all p0.001). Circuit weight training RPE (6.0 ± 1.1) was greater than TR (4.1 ± 0.6) (p0.001). There was no association between RPE and EE indices (p0.05). The average HR elicited by CT was 61% HR reserve. At equivalent HRs and duration, CT resulted in a significantly higher RPE but lower EE. It is imperative for subjects engaged in CT to understand that although CT results in HR values within an aerobic training zone and feels more strenuous, it is not associated with greater acute EE.

Background: Peripheral neuropathy is a common complication of diabetes which can lead to impaired postural control. The aim of the present study was to investigate the effect of 12-week resistance training on balance, risk of falling and distribution of foot pressure in diabetic women with peripheral neuropathy. Methods: In a randomized clinical trial, 30 women with type 2 diabetes and diagnosed with peripheral neuropathy were randomly assigned into experimental (n=15) and control (n=15) groups. The experimental group underwent a circuit resistance training program with 50 of one-maximum repetition, 3 -sessions per week over 12 weeks. Before and following the experimental period static and dynamic balance, posture control and risk of falling were assessed. Results: Static and dynamic balance indices improved following the exercise intervention (P=0.0001). Moreover, risk of falling index decreased in the experimental group compared to control condition (P=0.0001). However, foot pressure distribution was unchanged following exercise intervention (P>0.05). Conclusion: Circuit training improved balance and risk of falling in diabetic patients with peripheral neuropathy. Therefore, they are suggested to include circuit training as a safe non-pharmacological intervention to improve balance and walking and to prevent falling.

BACKGROUND: Impaired mobility is related to low physical activity (PA) levels observed after stroke. Therapeutic approaches, such as task-specific circuit training (TSCT), used to improve mobility in individuals with stroke, could also improve PA levels. OBJECTIVE: To investigate the efficacy of TSCT, focused on both upper (UL) and lower (LL) limbs, in improving PA levels and mobility (primary outcomes), as well as muscle strength, exercise capacity, and quality of life (secondary outcomes) in subjects with stroke. METHODS: A randomized controlled trial with 36 subjects with chronic stroke was conducted. Experimental group: TSCT, involving both UL and LL. Control group: global stretching, memory exercises, and education sessions. Both groups received 60 minute sessions/week over 12 weeks. Outcomes were measured at baseline, post-intervention and 16 week follow-up. RESULTS: No changes were found for primary and secondary outcomes (0.11≤p≤0.99), except for quality of life, which improved in the experimental group post-intervention and 16 week follow-up (p = 0.02). CONCLUSION: TSCT focused on both UL and LL was not effective on PA levels and mobility of individuals with chronic stroke, however, improvements in quality of life were observed. Since this is the first study to investigate this combined training aimed at improving PA levels, future studies are necessary to better understand the impact of this type of intervention.

The objective of this study was to identify the most important health/fitness trends while examining the impact of various demographics of respondents on the top trends for the first time in Greece. An online survey was sent to 3,487 professionals who worked in the health/fitness sector using the methodology of similar regional and worldwide studies extensively conducted by the American College of Sports Medicine (ACSM). A total of 542 responses were collected with a response rate of 15.5%. The ten most important trends were personal training, exercise is medicine, high-intensity interval training, small group training, and functional fitness, body weight training, exercise for weight loss, circuit training, strength training with free weights, and fitness programs for older adults. Health-related trends appear to be popular while technology- and mind/body-related trends seem not to be very attractive. Traditional exercise modes are still attractive and relevant, but specialized group training approaches are currently experiencing low popularity. Results also showed meaningful sex differences for 68% of the examined trends where female respondents reported higher scores. The main findings of this study are in line with those recently reported in the ACSM's European survey even though similar research design and data analysis are limited internationally.

Introduction Exercise induces modifications in thermal homeostasis. The type of exercise may have a specific impact on skin temperature (Tsk). Objective To analyze and compare the behavior of Tsk in a resistance training between men and women and monitor the thermal recovery response. Material and Methods Sixteen male and female adults (24.56 ± 3.22 years old) underwent a resistance circuit training session. They performed 3 sets of 12 repetitions with 70–80% 1 RM for lat pulldown, leg press, and biceps arm curl exercises. Thermograms were taken in anterior and posterior body view at rest, 20 min, and 24 h after training. Tsk was measured in the body regions of interest corresponding to the brachial biceps, quadriceps, and upper back. ANOVA with Tukey's post hoc test was used to analyze Tsk changes among moments, and independent samples t-test was used to compare Tsk between males and females.

Purpose The study was designed to investigate the effects of 12 weeks of circuit training and L-tryptophan supplementation on physical fitness and metabolic syndrome. Methods Forty-one menopausal women were randomly assigned to one of three groups. i.e., combined circuit training and L-tryptophan supplementation group (CT+T: n=14), L-tryptophan supplementation group (T: n=14), and control group (CON: n=13). The subjects in CT+T exercised three sessions per week and took 3g of L-tryptophan per day for 12 weeks. The subjects in T took 3g of L-tryptophan per day for 12 weeks. The subjects in CON were asked to maintain their life pattern for the same period of intervention. Physical fitness and metabolic syndrome-related variables were measured at pre- and post-test. The data were compared by utilizing a repeated two-way ANOVA. Results Main results of the study were as follows: 1) Standing long jump, one leg standing with eyes closed, sit-and-reach, sit-up, and maximal oxygen uptake increased significantly in CT+T. 2) Body weight, body mass index, waist circumference, waist-hip ratio, fat mass, and percent body fat decreased significantly in CT+T. 3) Total cholesterol decreased significantly in CT+T. 4) Fasting plasma glucose (FPG), fasting plasma insulin, and HOMA-IR decreased significantly in CT+T. FPG and HOMA-IR decreased significantly in T. 5) Systolic blood pressure, diastolic blood pressure (DBP), mean arterial pressure (MAP), and rate pressure product decreased significantly in CT+T. DBP and MAP decreased significantly in T. 6) Number of metabolic syndrome risk factors decreased significantly in CT+T and T. Conclusion It was concluded that the circuit training and L-tryptophan supplementation would have positive effects on physical fitness and metabolic syndrome, and that L-Tryptophan supplementation would have positive effects on metabolic syndrome by improving insulin resistance and hypertension in menopausal women.

Background Task-oriented circuit training using a Multi-Activities workstation emphasises goal-oriented tasks practiced in a circuit or series in order to learn a new skill. It can be used for upper limb rehabilitation among stroke patients in a community setting, but there is currently very little evidence available regarding its use in this patient group and setting. This study aimed to explore the influence of task-oriented circuit training using a Multi-Activities workstation on upper limb function among community-dwelling individuals with chronic stroke. Methods A pre-test–post-test study was conducted involving 17 community-dwelling individuals with chronic stroke who were attending a stroke rehabilitation centre. Six weeks of task-oriented circuit training was given using a Multi-Activities workstation aimed to improve strength, range of motion and dexterity. Streamlined Wolf Motor Function Test and Chedoke Arm and Hand Activity Inventory were used to measure outcomes. Wilcoxon signed-rank test was used for data analysis. Results A total of 12 sessions of task-oriented circuit training using Multi-Activities workstations did not result in any statistically significant differences in outcome measures. Conclusions Task-oriented circuit training using the Multi-Activities workstation did not improve upper limb function in community-dwelling individuals with chronic stroke.

Exercise is Medicine® on Campus (EIM-OC) is a global health initiative lead by the American College of Sports Medicine (ACSM) to integrate physical activity (PA) into university campus culture and establish PA as a vital sign.

Exercise training has positive effects on motor and cognitive performance which deteriorates over time in patients with Multiple Sclerosis (MS). The effects of task-oriented circuit training (TOCT) on motor and cognitive performance in patients with MS are not yet clear.The aims of this study are to investigate the effects of TOCT on balance, walking, manual dexterity, cognitive performance, and to determine the extent to which patients are able to transfer changes in their performance to activities of daily living.Twenty patients with MS (EDSS: 2-5.5), were randomly assigned to two groups; the task-oriented circuit training group (TOCTG, n:10) and the control group (CG, n:10). The TOCTG received TOCT twice a week for six weeks while the CG performed the relaxation exercises at home. All patients were assessed by using Modified Sensory Organization Test, Berg Balance Scale, Activities-specific Balance Confidence, Timed Up and Go, Functional Gait Assessment, 12-item Multiple Sclerosis Walking Scale, Nine-Hole Peg Test, Brief Repeatable Battery of Neuropsychological Tests, Multiple Sclerosis Neuropsychological Questionnaire.Balance and walking performance were improved after TOCT (p 0.05), whereas manual dexterity and cognitive performance except for verbal memory did not change significantly (p 0.05). The CG showed no changes in any measurements (p 0.05).TOCT is quite effective to improve balance and walking in patients with MS. However, further studies are needed to determine the effect of TOCT on cognitive performance.

Background An intensive task-oriented circuit training (TOCT) provides a valid approach in improving motor function in Multiple Sclerosis (MS). Objective We aimed at testing the efficacy of TOCT on gait kinematics in MS patients with mild-moderate disability. Methods Nineteen MS patients able of independent walking performed 3-D Gait Analysis before (T0) and after (T1) a two-week TOCT program. Patients were clustered in two different subgroups, according to clinical neurological impairments assessed with specific functional system of Expanded Disability Status Scale (EDSS): pyramidal (Group 1) and cerebellar (Group 2) subjects. Spatio-temporal and kinematic data were compared before and after the TOCT intervention in the total sample of patients and in the two selected subgroups at two time intervals. Results Data obtained revealed increased dynamic ROM at knee joint after training in the whole study sample. Of note, knee dynamic excursion improved significantly in Group 1 but not in Group 2 patients after TOCT. Moreover, sagittal plane kinematics revealed significant modifications on knee and ankle biomechanics in Group 1 after rehabilitation. Conclusions These data point out the benefits of the task specific training on gait dynamics in mild impaired MS subjects, linking to treatment opportunity in patients with a prevalent pyramidal impairment.

Background/objective: The integration of high-intensity interval training (HIIT) and circuit weight training (CWT) is seamless and practical for meeting recommended exercise guidelines. The purpose of this study was to determine the ideal combination of HIIT and CWT to elicit desired acute cardiorespiratory and metabolic responses in variables such as energy expenditure (EE), oxygen consumption (VO2), heart rate (HR), blood lactate (BLa−), excess post-exercise oxygen consumption (EPOC), rating of perceived exertion (RPE), and enjoyment. Methods: Fourteen trained males (25.7 ± 4.4 yr) completed two exercise protocols matched for volume and recovery periods. On one day, participants performed six HIIT bouts prior to three rounds of a nine exercise CWT protocol (HIC). The second day (separated by ≥ 72 h) consisted of three rounds of three mini-circuits (three exercises per circuit) integrated with three HIIT bouts between the first and second and second and third mini-circuits (TRI). VO2, HR, and EE were monitored throughout both protocols. EPOC for a 20-min duration, [BLa−] (five time points), RPE, and enjoyment were measured post-exercise. Results: Energy expenditure was significantly higher during the HIC compared to the TRI protocol (p = .012), as well as EPOC (p = .034). [BLa−] was significantly greater immediate-, 5min-, 10min- and 20min-post-exercise following HIC as compared to TRI. Mean values for HIC and TRI were similar (p > .05) for HR and RPE. Conclusion: Performing HIIT prior to CWT elicits a higher metabolic perturbation compared to the TRI protocol. Although a significant EE difference was detected between the two trials, the practical difference (∼20 kcal) between protocols indicates both protocols are similarly effective for caloric expenditure, metabolic and cardiorespiratory response. Keywords: High-intensity interval training, Circuit weight training, Resistance, Aerobic, Performance
