Background: Increments in inflammatory indicators and low levels of physical activity are correlated to the expansion of the metabolic syndrome (MetS). Objective: The purpose of this study was to establish if exercise training ameliorates inflammatory status in MetS patients. Data sources: PubMed, CINAHL, and Medline, Google Scholar, and Scopus databases and reference lists of included studies were searched. Study selection: Twenty randomized controlled trials (RCTs) of exercise-training impact on inflammatory markers (tumor necrosis factor (TNF) α, C-reactive protein (CRP), interleukin (IL) 6, IL-8, IL-10, and IL-18) with concurrent control groups were included in this analysis. Results: Results demonstrated an overall significant decrease in serum levels of TNF-α (mean difference (MD): −1.21 pg/ml; 95% confidence interval (CI): −1.77, −0.66), CRP (MD: −0.52 mg/l; 95% CI: −0.79, −0.25), IL-8 (MD: −1.31 pg/ml; 95% CI: −2.57, −0.06), and a significant increase in IL-10 (MD: 0.48 pg/ml; 95% CI: 0.10, 0.86). But exercise training did not change the level of IL-6 (MD: −0.69 pg/ml; 95% CI: −1.53, 0.14) and IL-18 (MD: −53.01 pg/ml; 95% CI: −166.64, 60.62). Conclusion: Exercise training improves TNF-α, CRP, IL-8, and IL-10 levels in patients with MetS. For some variables, isolated aerobic exercise, and combined aerobic and resistance exercise appears to be optimal. Future research is needed to clarify the mechanisms underlying exercise training’s effect on this population’s inflammatory markers. More studies are required to confirm these findings.

Background: Physical inactivity and an imbalanced diet could lead to some cardio metabolic risk factors. Objective: The objective of this meta-analysis was to investigate the effects of lifestyle modification on inflammatory indicators and waist circumference (WC) in overweight/obese subjects with metabolic syndrome (MS) Data sources: A systematic search was conducted in PubMed, CINAHL, MEDLINE, Cochrane, Google Scholar, and Web of Science. Study selection: The selection criteria were randomized controlled trials (RCTs) investigating the effects of lifestyle interventions on inflammation and WC from inception to 20 December 2020. The weighted mean difference (WMD) and 95% confidence interval (CI) between interventions were computed using a random or fixed-effects model. Results: Six RCTs (including 1246 MS patients who had, on average, overweight/obesity) met all inclusion criteria. Interventions lasted 6 to 12 months (2–5 sessions per week). Lifestyle intervention significantly reduced C-reactive protein (WMD: −0.52 mg/ml, 95% CI: −0.72, −0.33), IL-6 (WMD: −0.50 pg/ml, 95% CI: −0.56, −0.45), and increased adiponectin (WMD: 0.81 µg/ml, 95% CI, 0.64, 0.98). Moreover, lifestyle modification significantly decreased WC (WMD: −3.12 cm, 95% CI, −4.61, −1.62). Conclusion: Our findings provide evidence that lifestyle alterations, including physical activity and diet, can lead to significant improvement in abdominal obesity, measured by WC and some inflammation markers among overweight/obese individuals with MS. Further high-quality research is needed to clarify the mechanisms underlying the effect of such interventions on this population’s inflammatory markers.

Background and study aim. The purpose of this study was to determine the relative contribution of energy systems in a freestyle (FS) and a Greco-Roman (GR) wrestling match, quantity and quality of obtained scores, and the competition efficiency of winners in the 2017 Wrestling World Championships (WCh) through analysing the recorded videos of all the matches of this event. Material and method. The materials of the present study were 295 FS and 266 GR recorded videos of the 2017 WCh, a multimedia player (lap top) for watching and analysing them, and a chronometer for recording the different duration of activities happening during these matches. In addition, special papers were designed in advance to make sure that all the required data were recorded properly. Result. The percentages of ATP-PC (ATP), lactic (LAC), and aerobic (AERO) energy systems were 6.66, 62.74, and 30.60 in FS, and 5.94, 67.53, and 26.53 in GR. Quantity and quality analysis of scores showed that FS wrestlers significantly scored more 1- and 4-point, while GR wrestlers were superior regarding the quality 2-point. The average competition efficiency of gold medallists was 18/43±4/67 in FS and 15/87±3/18 in GR which were statistically significantly greater than that of all other placers. Conclusion. This study showed the dominance of LAC in a wrestling match in both styles, although their relative contribution was significantly different between styles. In addition, FS wrestlers significantly scored more points, and Gold medallists demonstrated the greatest average competition efficiency compared to other medallists.
