摘要

背景:运动干预可以促进健康,但很难实施。此外,对于哪种运动方式能促进代谢健康的最显著改善,还没有达成共识。目的:本可行性研究旨在(a)通过调查干预依从性、目标强度依从性、消耗和不良事件的发生率,确定监督和家庭锻炼干预措施的实施效果,有氧运动与阻力运动相结合,以及针对身体成分、人体测量参数和脂质状况的高强度间歇训练,为身体不活动的社区居民提供。方法:本随机对照试验于2020年4月至10月进行。72名年龄在40-70岁的久坐不动的参与者被招募并随机分为四组之一:12周有氧运动、有氧运动结合阻力运动、高强度间歇训练和对照。三个锻炼组每周进行两次至少中等强度的监督锻炼,每周进行一次家庭锻炼,而对照组则保持日常活动。在12周干预前后测量目标变量,包括身体成分、人体测量参数和脂质状况。结果:监督运动组的干预依从率为74.01%-87.54%,家庭运动组为64.98%-83.90%,目标运动强度组为82.65%-92.65%。消耗率在12.50%至17.65%之间,任何运动组均未报告不良事件。初步疗效数据显示,与对照组相比,运动组的体重(95%CI[0.012.20],p=0.048)和低密度脂蛋白(95%CI[2.76,30.32],p=0.02)下降幅度更大,尽管组间差异并不显著。结论/实践意义:使用三种运动方式中的任何一种,在12周内都可以有效降低体重和低密度脂蛋白,坚持中等强度运动至少82.65%,坚持每周运动3次至少70.84%。

Feasibility of Different Exercise Modalities for Community-Dwelling Residents With Physical Inactivity: A Randomized Controlled Trial.

Background: Exercise interventions can promote health, but they can be difficult to implement. Moreover, no consensus has been reached regarding which exercise modality promotes the most significant improvement in metabolic health.

Purpose: This feasibility study was conducted to (a) determine the implementation efficacy of supervised and home-based exercise interventions by investigating their respective rates of intervention adherence, adherence to targeted intensity, attrition, and adverse events and (b) explore the preliminary efficacy of 12-week exercise programs among aerobic exercise, aerobic exercise combined with resistance exercise, and high-intensity interval training on body composition, anthropometric parameters, and lipid profiles for community-dwelling residents with physical inactivity.

Methods: This randomized controlled trial was conducted from April to October 2020. Seventy-two sedentary participants aged 40-70 years were enrolled and randomized into one of four groups: 12-week aerobic exercise, aerobic exercise combined with resistance exercise, high-intensity interval training, and control. The three exercise groups performed at least moderate-intensity supervised exercise twice a week and home-based exercise once a week, whereas the control group maintained their usual daily activities. The target variables, including body composition, anthropometric parameters, and lipid profiles, were measured before and after the 12-week intervention.

Results: The intervention adherence rates were 74.01%-87.54% for the supervised exercise group, 64.98%-83.90% for the home-based exercise group, and 82.65%-92.65% for the target exercise intensity group. The attrition rate ranged from 12.50% to 17.65%, and no adverse events were reported in any of the exercise groups. Preliminary efficacy data show the reductions in body weight (95% CI [0.01, 1.20], p = .048) and low-density lipoprotein (95% CI [2.76, 30.32], p = .02) were greater in the exercise groups than the control group, although the intergroup differences were not significant.

Conclusions/implications for practice: Body weight and low-density lipoprotein may be efficiently reduced in a 12-week period using any of the three exercise modalities with at least 82.65% adherence to moderate-intensity exercise and 70.84% adherence to exercising 3 times a week.
