“…In 21 sarcopenic obese adults aged 60 years or older randomised to 15 weeks of strength/hypertrophy or high speed (power) circuit training, no differences were observed for changes in body fat and physical performance, but lower-limb power tended to improve more for the circuit training group [80]. In a factorial design RCT involving 38 postmenopausal women with dynapenic obesity randomised to either 12-weeks of PRT, caloric restriction, both or a control group, caloric restriction alone or in combination with PRT was associated with an improvement in body weight, fat mass and cardiometabolic health while PRT had a beneficial effect on physical performance [81]. The findings from these small trials are supportive of the concept that multimodal exercise interventions incorporating PRT and combined with caloric restriction are effective therapies for sarcopenic and dynapenic obesity.…”

Due to their differing etiologies and consequences, it has been proposed that the term "sarcopenia" should revert to its original definition of age-related muscle mass declines, with a separate term, "dynapenia", describing muscle strength and function declines. There is increasing interest in the interactions of sarcopenia and dynapenia with obesity. Despite an apparent protective effect of obesity on fracture, increased adiposity may compromise bone health, and the presence of sarcopenia and/or dynapenia ("sarcopenic obesity" and "dynapenic obesity") may exacerbate the risk of falls and fracture in obese older adults. Weight loss interventions are likely to be beneficial for older adults with sarcopenic and dynapenic obesity but may result in further reductions in muscle and bone health. The addition of exercise including progressive resistance training and nutritional strategies, including protein and vitamin D supplementation, may optimise body composition and muscle function outcomes thereby reducing falls and fracture risk in this population.

“…However, the role of RT volume on fat loss in PW is not clear. The RT protocol used to promote hypertrophy has shown modest to no effect on indicators of body fat and metabolic risk in PW (Brochu et al 2009;Lera Orsatti et al 2014;Maesta et al 2007;Phillips et al 2012;Senechal et al 2012), and there are no studies that have used more than three sets on indicators of body fat and metabolic risk in PW. Studies using acute resistance exercise have shown that higher RT volume is associated with higherenergy expenditure (Haddock and Wilkin 2006;Phillips and Ziuraitis 2004) and with greater activation of signaling pathways that regulate PGC-1α (Ahtiainen et al 2015;Combes et al 2015).…”

“…The American College of Sports Medicine (ACSM) recommends resistance training (RT; two to three times a week, eight to ten exercises, and one to three sets of 8-15 repetitions at 60-80 % of one repetition maximum) to improve muscular mass and strength and avoid sarcopenia in the elderly (American College of Sports 2009; Garber et al 2011). Another well-established benefit of RT is the prevention of abdominal and total fat gain and increases in markers of both inflammation and metabolic risk factors (American College of Sports 2009;Garber et al 2011;Lera Orsatti et al 2014;Maesta et al 2007;Orsatti et al 2010a;Phillips et al 2012;Senechal et al 2012). However, it has been established that a higher volume (amount) of exercise (or higher energy expenditure) reduces abdominal fat and metabolic risk factors in overweight and obese people (American College of Sports 2009;Friedenreich et al 2015;Garber et al 2011;Lera Orsatti et al 2014;Nimmo et al 2013).…”

This study evaluated the effect of resistance training (RT) volume on muscular strength and on indicators of abdominal adiposity, metabolic risk, and inflammation in post-menopausal women (PW). Thirty-two volunteers were randomly allocated into the following three groups: control (CT, no exercise, n = 11), low-volume RT (LV, three sets/exercise, n = 10), and high-volume RT (HV, six sets/exercise, n = 11). The LV and HV groups performed eight exercises at 70 % of one maximal repetition, three times a week, for 16 weeks. Muscular strength and indicators of abdominal adiposity, metabolic risk, and inflammation were measured at baseline and after 16 weeks. No differences were found in baseline measures between the groups. The PW showed excess weight and fat percentage (F%), large waist circumference (WC), high waist-hip ratio (WHR), and hypercholesterolemia and borderline values of glycated hemoglobin (HbA1c%). Following the RT, a similar increase in muscle strength and reduction in F% from baseline were found in both trained groups. In HV, a decrease in total cholesterol, LDL-c, WC, and WHR was noted. Moreover, the HV showed a lower change (delta%) of interleukin-6 (IL-6) when compared to CT (HV = 11.2 %, P 25-75 = -7.6-28.4 % vs. CT = 99.55 %, P 25-75 = 18.5-377.0 %, p = 0.049). In LV, a decrease was noted for HbA1c%. There were positive correlations (delta%) between WHR and IL-6 and between IL-6 and TC. These results suggest that while a low-volume RT improves HbA1c%, F%, and muscular strength, a high-volume RT is necessary to improve indicators of abdominal adiposity and lipid metabolism and also prevent IL-6 increases in PW.

“…However, it is unclear whether RT represents a good strategy to prevent muscle loss during CR (which includes dietary protein restriction). Some studies have reported no change or even reduced LBM following CR when RT is included in the intervention program [ 7 , 14 , 15 , 16 , 17 , 18 ]. On the other hand, randomized clinical trials (RCT) comparing CR with and without RT have shown the preservation of LBM with RT [ 19 , 20 ].…”

Resistance Training Prevents Muscle Loss Induced by Caloric Restriction in Obese Elderly Individuals: A Systematic Review and Meta-Analysis

It remains unclear as to what extent resistance training (RT) can attenuate muscle loss during caloric restriction (CR) interventions in humans. The objective here is to address if RT could attenuate muscle loss induced by CR in obese elderly individuals, through summarized effects of previous studies. Databases MEDLINE, Embase and Web of Science were used to perform a systematic search between July and August 2017. Were included in the review randomized clinical trials (RCT) comparing the effects of CR with (CRRT) or without RT on lean body mass (LBM), fat body mass (FBM), and total body mass (BM), measured by dual-energy X-ray absorptiometry, on obese elderly individuals. The six RCTs included in the review applied RT three times per week, for 12 to 24 weeks, and most CR interventions followed diets of 55% carbohydrate, 15% protein, and 30% fat. RT reduced 93.5% of CR-induced LBM loss (0.819 kg [0.364 to 1.273]), with similar reduction in FBM and BM, compared with CR. Furthermore, to address muscle quality, the change in strength/LBM ratio tended to be different (p = 0.07) following CRRT (20.9 ± 23.1%) and CR interventions (−7.5 ± 9.9%). Our conclusion is that CRRT is able to prevent almost 100% of CR-induced muscle loss, while resulting in FBM and BM reductions that do not significantly differ from CR.
