“…Most secondary outcomes also revealed an inverted U-shaped dose-response pattern favoring G2 (Table 1). Decreases of up to 5% in body mass agree with weight loss reported after multimodal training in adults and can meaningfully reduce risks for cardiovascular disease even in normal-weight adults at mid-late life [28]. The pattern of changes in PA indeed raises questions about the IPAQ’s validity because while participants in G2 reported the expected increases in (vigorous) PA in proportion to the 2× per week exercise, that was not the case in G3, reporting in fact less increase in PA than G2 and G1 (Table 1).…”

Background: Office workers near retirement tend to be sedentary and can be prone to mobility limitations and diseases. We examined the dose effects of exergaming volume and duration of detraining on motor and cognitive function in office workers at late midlife to reduce sedentariness and mobility limitations. Methods: In an assessor-blinded randomized trial, 160 workers aged 55–65 years performed physically active video games in a nonimmersive form of virtual reality (exergaming) in small, supervised groups for 1 h, 1×, 2×, or 3×/week for 8 weeks followed by detraining for 8 and 16 weeks. Exergaming comprises high-intensity, full-body sensorimotor coordination, balance, endurance, and strengthening exercises. The primary outcome was the 6-minute walk test (6MWT), and secondary outcomes were body mass, self-reported physical activity, sleep quality, Berg Balance Scale, Short Physical Performance Battery, fast gait speed, dynamic balance, heart rate recovery after step test, and 6 cognitive tests. Results: The 3 groups were not different in any of the outcomes at baseline (all p > 0.05). The outcomes were stable and had acceptable reliability (intraclass correlation coefficients ≥0.334) over an 8-week control period. Training produced an inverted U-shaped dose response of no (1×), most (2×), and medium (3×/week) effects of exergaming volume in most motor and selected cognitive outcomes. The distance walked in the 6MWT (primary outcome) increased most (94 m, 19%, p < 0.05), medium (57 m, 12%, p < 0.05), and least (4 m, 1%) after exergaming 2×, 3×, or 0× (control) (all different p < 0.05). The highest responders tended to retain the exercise effects over 8 weeks of detraining, independent of training volume. This maintenance effect was less consistent after 16 weeks of detraining. Conclusion: Less was more during training and lasted longer after detraining. A medium dose volume of exergaming produced the largest clinically meaningful improvements in mobility and selected cognitive tests in 60-year-old office workers with mild mobility limitations and intact cognition.

“…In this study, circuit training was applied as an exercise intervention method. According to a recent meta-analysis, circuit exercise is known to effectively reduce body weight and BMI in people with obesity [30]. In a 16-week pilot intervention program by our research group, we found that BMI z-score, the primary outcome of the intervention, was significantly decreased in the exercise group with circuit training compared to the baseline after the intervention, but the changes in BMI z-score were not significantly different between groups [28].…”

Objective We aimed to assess the effectiveness of the first 6 months of a 24 month multidisciplinary intervention program including circuit training and a balanced diet in children and adolescents with obesity. Methods A quasi-experimental intervention trial included 242 participants (age [mean±standard deviation]: 11.3±2.06 years, 97 girls) of at least 85th percentile of age- and sex-specific body mass index (BMI). Participants were grouped into three to receive usual care (usual care group), exercise intervention with circuit training (exercise group), or intensive nutritional and feedback intervention with a balanced diet (nutritional group). Primary outcome was BMI z-score, while secondary outcomes included body composition, cardiometabolic risk markers, nutrition, and physical fitness. Results Among the participants, 80.6% had a BMI ≥ the 97th percentile for age and sex. The BMI z-score of the overall completers decreased by about 0.080 after 6 months of intervention (p < 0.001). After the intervention, both exercise and nutritional groups had significantly lower BMI z-scores than the baseline data by about 0.14 and 0.075, respectively (p < 0.05). Significant group by time interaction effects were observed between exercise versus usual care group in BMI z-score (β, -0.11; 95% confidence interval (CI), -0.20 to -0.023) and adiponectin (β, 1.31; 95% CI, 1.08 to 1.58); and between nutritional versus usual care group in waist circumference (β, -3.47; 95% CI, -6.06 to -0.89). No statistically significant differences were observed in any of the other secondary outcomes assessed. Conclusion Multidisciplinary intervention including circuit training and a balanced diet for children and adolescents with obesity reduced the BMI z-score and improved cardiometabolic risk markers such as adiponectin and waist circumference.

“…The parameters of the exercise protocol were not sufficient to produce meaningful effects on the body composition variables. A series of meta-analysis [58,59] reported that CT improves body composition in obese/ overweight population but the effect varied among the studies. Studies with comparable duration (8-weeks) showed significant improvement in BW, BMI and WHR in obese men [43,60], but no effect on these body composition outcomes in obese women [44].…”

Background: Obesity has become a serious problem in Western societies and is associated with several health problems and reduced quality of life. The purpose of this randomised, clinical trial is to investigate the effects of a moderate-intensity, intermittent, circuit training program on a range of cardiovascular risk factors such as body composition, biochemical and physiological variables and aerobic capacity in obese and overweight individuals. Methods: A total of 30 participants were selected and 15 of them performed a moderate-intensity, intermittent, circuit training program; whereas the rest acted as a control-group. The circuit training program consisted of 10 exercise stations and was performed 2 times per week for 8-weeks in total. The experimental group performed a circuit training program with training cycles at 50-60% of heart rate reserve which were followed by active recovery periods at 40-50% of heart rate reserve. Control-group remained sedentary during the period of 8-weeks and follow-up. Biochemical markers, isometric strength, body composition and physiological parameters were assessed at baseline and 8-weeks post-intervention, whereas maximal oxygen consumption was assessed at baseline, 8-weeks and 2-months follow-up.Results: Significant improvements were demonstrated in BW (2.5%), BMI (~3%), BF% (~4%), BF-Kg (~6%), and LBM% (3.3%), SBP (5.3%), HR-resting (4.3%), MAP (~5%) and cardiorespiratory fitness (~11%) in the exercise group post-intervention. Significant time by group interaction was found for all physiological variables (SBP, DBP, HR, MAP, RPP) in favour of the exercise group. VO2peak improved post-intervention by ~11% in the CT-group, in contrast to 1.7% in the control-group. Conclusion:The present data suggest that a moderate-intensity, intermittent circuit training program for 8-weeks may be effective in reducing cardiovascular risk factors.
