Popis: IntroductionThis study investigated the effect of Yijinjing combined with elastic band exercise on muscle mass and muscle function in patients with prediabetes.MethodsThis study was a randomized controlled trial designed in parallel (Chinese Clinical Trial Registry: ChiCTR2000039049). Participants with prediabetes (n = 47) were randomly divided into control (n = 21, 63.5 ± 4.7 years,16 females) and exercise (n = 26, 62.0 ± 5.0 years, 20 females) groups. The former maintained their original lifestyle, and the latter received Yijinjing combined with elastic band exercise five times a week for 6 months. All the outcome measures were assessed immediately at baseline, after 3- and 6-month intervention.ResultsAfter 6-month of the exercise, the body weight, body mass index, leg fat mass, gynoid fat mass, and total body fat mass in exercise group were significantly decreased compared with those at baseline (p < 0.05). Compared with those at baseline, total lean mass decreased at 3 and 6 months in both groups. The total muscle mass loss in the exercise group was always less than that in control group at all time periods, but the difference was not statistically significant. Handgrip strength, gait speed, reaction time, leg power, eye-closed and single-legged standing, and sit-and-reach were significantly improved for the exercise group at 3 and 6 months (p < 0.05). Gait speed and reaction time between both groups at 3 and 6 months were significant different (p < 0.05), and leg power at 6 months (p < 0.05). Compared with baseline, the reaction time of control group at six months was significantly improved (p < 0.05), and no other significant changes were observed. Compared with those at baseline, fasting plasma glucose, 2-h post-meal plasma glucose, fasting insulin, total cholesterol, and insulin resistance index in exercise group gradually decreased, and growth hormone was gradually increased with significance at 6 months (p < 0.05). 25-hydroxyvitamin D gradually and significantly increased in both groups at 3 and 6 months (p < 0.05). But two groups’ testosterone levels weren’t significant change.ConclusionYijinjing combined with elastic band exercise can substantially reduce the body weight and body fat content of middle-aged and elderly patients with Prediabetes, improve muscle function and growth hormone secretion, and delay muscle mass reduction and diabetes development.Clinical trial registration[http://www.chictr.org.cn/showproj.aspx?proj=62753], identifier [ChiCTR2000039049].
