(1) Background: Exercise interventions for overweight and obese individuals help reduce accumulated visceral fat, which is an indicator of cardiometabolic risk, but the effectiveness of these interventions is controversial. The purpose of this meta-analysis was to investigate the effectiveness of exercise interventions in overweight and obese individuals in order to reduce weight, body mass index (BMI), and accumulated visceral fat, and increase lean body mass. (2) Methods: Databases were used to select eligible studies for this meta-analysis. Randomized controlled trials with control and experimental groups were included. The degrees of effectiveness of the exercise interventions were computed to assess the benefits on reducing weight, BMI, and accumulated visceral fat, and increasing lean body mass. (3) Results: Sixteen studies were included in this meta-analysis. Participation in exercise interventions reduced weight (d = −0.58 (95% confidence interval (CI), −0.84–−0.31; p < 0.001; k = 9)), BMI (d = −0.50 (95% CI, −0.78–−0.21; p < 0.001; k = 7)), and accumulated visceral fat (d = −1.08 (95% CI, −1.60–−0.57; p < 0.001; k = 5)), but did not significantly increase lean body mass (d = 0.26 (95% CI, −0.11–0.63; p = 0.17; k = 6)). The average exercise intervention for overweight and obese individuals was of moderate to vigorous intensity, 4 times per week, 50 min per session, and 22 weeks duration. (4) Conclusions: Participating in exercise interventions has favorable effects on weight, BMI, and accumulated visceral fat. Further studies considering different modalities, intensities, durations, and measurements of fatness need to be conducted.

Abstract Objectives Classic short-term nitrogen balance research estimated that the Recommended Dietary Allowance (RDA) of 0.8 g protein/kg/d would be adequate to maintain whole-body nitrogen balance in 97.5% of the population. However, achieving whole-body nitrogen balance does not necessarily equate with tissue-specific amino acid (nitrogen) needs, for example in skeletal muscle. The objective of this systematic review and meta-analysis was to assess in weight-stable adults the effects of chronically consuming greater than the protein RDA, compared to the RDA, on whole-body composition. Methods Articles published through 2018 were identified with PubMed, Scopus, Cochrane, and CINAHL databases. Five articles with 7 comparisons were identified to be relevant through the databases and through screening previous published reviews. Two researchers independently screened the articles for eligible randomized controlled trials (RCTs) of parallel design that measured changes in body composition after ³6 wk of dietary control. Results There was significant heterogeneity in the effect sizes amongst the comparisons (I2  = 72.8%, χ2  = 22.1, P = 0.001). Consuming greater than the protein RDA did not differentially affect any of the changes in total body mass [0.07 kg (−0.75, 0.88); WMD, (95% CI), Random effects], fat mass [−0.65 kg (−1.33, 0.03)], or lean body mass [0.08 kg (−0.59, 0.75)]. Conclusions These results from controlled feeding RCTs support adequacy of the protein RDA to retain lean body mass and indicate that protein intakes greater than the RDA do not promote morphological changes among weight-stable adults.

Exercise intervention has a positive effect on reducing the fall risk in older adults. To investigate the effect of different factors of exercise intervention (type, duration, and frequency) on reducing the fall risk in older adults, a meta-analysis was performed in this study. According to the PRISMA®, two researchers independently searched PubMed, Web of Science, and the China National Knowledge Infrastructure databases to assess the quality of the studies using the PEDro scale. A total of 648 subjects in 10 randomized controlled trials were included in this study, and the exercise interventions included integrated training (resistance training, core training, and balance training), balance training, core training, Pilates, Ba Duan Jin, and Tai Chi. These studies show that exercise intervention has a huge and significant impact on reducing the risk of falls of the elderly. In conclusion, an integrated intervention with a frequency of more than five times a week and a duration of more than 32 weeks are more effective in reducing the fall risk.

Cancer Trajectory

Cancer related fatigue (CRF) is one among the common distressing symptoms experienced by cancer patients. Evidence showed that exercise interventions are effective in decreasing CRF. This review is to evaluate the evidence of the effectiveness of exercise interventions on CRF among adults with varied types of cancer in all phases of the cancer trajectory. A literature review with meta-analysis of randomized controlled trials (RCTs) was conducted. The results of RCTs (n = 20) that examined the effects of exercise on CRF were combined using two approaches: meta-analysis (n = 18) and summative analysis (n = 2). A summary effects size of the standardized mean difference (SMD) with 95% confidence intervals was calculated using random effects model and heterogeneity was assessed with the I2 statistic. The results showed overall, a small but significant decrease in the level of CRF (SMD, -0.32; 95% CI, -0.51 to -0.12; p = .002) was observed following exercise intervention. Subgroup analyses showed that both mixed modes (combination of resistance and aerobic exercises) and aerobic exercises were effective in significantly reducing CRF (p = .033; p = .046 respectively). The results indicated substantial heterogeneity between studies (I2 = 79%; p ≤ .0001). Summative analysis also suggested that exercise may be effective in reducing CRF. In conclusion, both resistance and aerobic exercises may be effective in decreasing CRF in adult patients. The result needs to be interpreted with caution due to considerable between-study heterogeneity.
