A systematic review with meta-analysis was conducted to evaluate the effects of circuit resistance training (CRT) on cardiorespiratory fitness, strength, and body composition in middle-aged and older women. Sixteen studies were included in the meta-analysis. The CRT interventions led to a significant decrease in weight, body mass index, and fat mass along with an increase in muscle mass. Significant differences were found in the fat mass and a trend to develop muscle mass when compared with the control group. CRT led to a significant increase in VO2max, walking endurance, and time to exhaustion; likewise, significant differences were observed when compared with the control group. CRT had a moderate and large favorable effect on arm, trunk, and lower limb strength. Furthermore, the increases in strength observed in the CRT were significantly greater than the changes observed in the control group. In middle-aged and older women, CRT improved cardiorespiratory fitness and strength and optimized body composition.

AbstractBackgroundProgranulin (PGRN) is implicated in obesity and insulin resistance (IR). The aim of this study was to evaluate the effects of 8 weeks of circuit resistance training (CRT) on plasma PGRN, IR and body composition in obese men.Materials and methodsTwenty-eight healthy obese men [age: 36 ± 7.7 years, body weight (BW): 96.4 ± 15.6 kg, body mass index (BMI): 32.4 ± 4.5 kg/m2] completed the study. Subjects were randomly assigned to two groups of control and training. Subjects in the training group underwent training for 8 weeks, 3 times a week. Blood samples and anthropometric characteristics were taken before the commencement of the exercise protocol and 72 h after the last training session. The homeostatic model assessment of insulin resistance (HOMA-IR) was used to measure IR.ResultsBW, BF%, BMI, waist-hip ratio (WHR), HOMA-IR and plasma PGRN levels except lean body mass (LBM) were significantly reduced in the training group (p < 0.05). Additionally, except for LBM, subjects in the training group had significantly decreased BW, BF%, BMI, WHR, HOMA-IR and plasma PGRN levels compared to changes in those in the control group (p < 0.05). Significant correlations were found between the changes in plasma PGRN and the changes in insulin, HOMA-IR and BMI (p < 0.05).ConclusionsThe findings showed that 8 weeks of CRT improved body composition and IR which were accompanied by reduced plasma PGRN levels. This study suggests that CRT has the potential for obese individuals to counteract obesity-associated health impairments.

We assessed the effects of resistance circuit-based training (CT) on strength, cardiorespiratory fitness, and body composition. A systematic review with meta-analysis was conducted in three databases, ending on March, 2020. Meta-analysis and subgroup analysis were used to analyze the effects of pre–post-intervention CT and differences from control groups (CG). Of the 830 studies found, 45 were included in the meta-analysis (58 experimental groups (n = 897) and 34 CG (n = 474)). The CT interventions led to increases in muscle mass (1.9%; p < 0.001) and decreases in fat mass (4.3%; p < 0.001). With regard to cardiorespiratory fitness, CT had a favorable effect on VO2max (6.3%; p < 0.001), maximum aerobic speed or power (0.3%; p = 0.04), and aerobic performance (2.6%; p = 0.006) after training. Concerning strength outcome, the CT increased the strength of the upper and lower extremities. Only the magnitude of strength performance appears to be influenced by the training (number of sessions and frequency) and the training status. Moreover, low and moderate intensities and short rest time between exercise increase the magnitude of change in fat mass loss. Therefore, CT has been shown to be an effective method for improving body composition, cardiorespiratory fitness, and strength of the lower and upper limbs.

Objective: The overweight-related health problems among adolescents are obvious. Resistance training is recognized as a safe and efficacious exercise modality to have health-promoting effects in overweight adolescents. This study aimed to assess the efficacy of circuit resistance training (CRT) in improving inflammatory status, insulin resistance and body composition in overweight male adolescents. Materials and Methods: Twenty overweight adolescent boys (aged: 18.5 (±1), weight: 81.1 (±4.5), body mass index: 27.7 (±0.7)) completed this study. The participants were randomly and equally divided into two groups of control (CG; n=10) and circuit resistance training (CRT; n=10). The CG did their daily routine activities and the CRT group performed its training protocol 3 days a week for 6 weeks. Body composition components and serum variables were measured a day before and after the study. Insulin resistance index was measured by HOMA-IR. Results: The subjects in the CG showed significantly increased changes compared with pre-training values. Moreover, significant changes were found fort the changes of BW ( P -value= 0.005), BMI ( P -value= 0.001) and BF% ( P -value= 0.003) between groups. Conclusion: This study suggested that although six weeks of CRT failed to induce meaningful anti-inflammatory cytokine responses, and to improve body composition and HOMA-IR in overweight adolescent boys, but had protective effects on inflammatory status, HOMA-IR and body composition and prevented them from being deteriorated

Few studies have examined the improving effects of exercise on the association between metabolites of impaired protein metabolism and insulin resistance in obese children. Therefore, this study aims to investigate the effect of circuit resistance training (CRT) on plasma levels of amino acids, alpha-hydroxybutyrate (α-HB), mannose, and urinary levels of glycine conjugated adducts in obese adolescent boys. Forty obese adolescent boys (BMI above the 95th percentile) with an age range of 14-17 were randomly divided into CRT group (n= 20) and control group (n= 20). The CRT program (3 times/week, 70-80% of 1 repetition maximum) was performed for 8 weeks. The results indicated that the body composition and plasma levels of glucose, insulin resistance, valine, mannose, lysine and the sum of branched-chain amino acids (BCAAs) were decreased due to CRT. The plasma levels of asparagine, glycine, serine, and urinary levels of glycine conjugated adduct also increased in the CRT group. Although α-HB level decreased during CRT, it had no significant difference from that of the control group. It can be concluded that the improvement in obesity complications including insulin resistance in obese adolescent boys after CRT may be due to decrease in plasma levels of mannose and BCAAs and increase urinary metabolites. Novelty Bullets: • CRT improves glucose metabolism and insulin resistance in obese adolescent boys. • CRT decreases plasma levels of mannose and BCAAs and normalizes other amino acids. • CRT increases urinary levels of glycine conjugated adducts.

Abstract Objectives Under stressful conditions such as energy restriction (ER) and resistance training (RT), recommended dietary allowance (RDA) for protein of 0.8 g/kg/d may no longer be an appropriate recommendation. Higher protein intakes are proposed to help promote, preserve, or attenuate the loss of lean mass. No known meta-analysis has been published previously that compares protein intakes greater than the RDA vs. the RDA as a control group. Therefore, we conducted a systematic review and meta-analysis to assess the effects of protein intake greater than versus at the RDA on changes in whole-body lean mass. Methods Three researchers independently screened 1531 articles published through August 2018 using PubMed, Scopus, CINAHL, and Cochrane databases, with additional articles identified through previously published review articles. Randomized-controlled, parallel studies at least 6 weeks long with apparently healthy adults (> = 19 years old) were eligible for data extraction. (PROSPERO, CRD 42018106532). Results Data from 19 studies resulting in 23 comparisons of lean mass changes were included in the final analysis. This abstract presents sub-analyses for comparisons with catabolic and anabolic stimuli, specifically ER and/or RT, respectively. Among all comparisons, protein intakes greater than the RDA attenuated lean mass loss after ER [0.41 kg (0.15, 0.67); WMD (95% CI), n = 15 comparisons], but did not influence lean mass change without ER [0.23 kg (−0.44, 0.89), n = 8]. Protein intakes greater than the RDA increased lean mass after RT [0.77 kg (0.23, 1.31), n = 3], but not influence change in lean mass without RT [0.29 kg (−0.04, 0.62, n = 20]. Conclusions Protein intakes greater than the RDA positively influence changes in lean mass when adults are purposefully stressed by the catabolic stimulus of dietary energy restriction and/or the anabolic stimulus of resistance training. The RDA for protein is adequate for adults during non-stressed states. Funding Sources Purdue University Lynn Fellowship. No external funding was provided for this review.
