PURPOSE This study aimed to examine adherence to the weekly physical activity guidelines (≥150 min of aerobic activities at moderate-to-vigorous intensity and two or more sessions of strength training (yes or no)) and health outcomes during the COVID-19 pandemic for men living with obesity, 46 wk after being offered an online muscle-strengthening circuit program for 12 wk. METHODS Sixty men (age ≥19 yr) living with obesity (body fat percentage ≥25%) were randomly assigned to the intervention group ( n = 30) or the control condition ( n = 30) for 12 wk. The intervention group was offered an online circuit training, three sessions per week, whereas the control group received a website helping them to reach the physical activity guidelines. Adherence to the weekly physical activity guidelines was evaluated 46 wk after enrolling in the program using a heart rate tracker (Fitbit Charge 3) and an exercise log. Health outcomes (e.g., anthropometrics, body composition) were measured at baseline and after 12, 24, and 46 wk. RESULTS The intervention group had higher adherence to physical activity guidelines at 46 wk (36.8%) than the control group (5.3%; P = 0.02). However, no difference in health outcomes was observed between participants in the intervention group compared with the control group after 12, 24, and 46 wk. CONCLUSIONS Increasing adherence to exercise in men living with obesity is challenging. The proposed program increased adherence to the physical activity guidelines after about a year for men living with obesity; however, more studies are needed to understand how to improve health outcomes when following an online delivery exercise program in this population.

在线循环训练增加对体育活动的坚持：对肥胖男性的随机对照试验。

目的 本研究旨在检查在 COVID-19 大流行期间对每周身体活动指南（≥150 分钟中等至剧烈强度的有氧运动以及两次或两次以上力量训练（是或否））的遵守情况以及健康结果对于肥胖男性，在接受为期 12 周的在线肌肉强化循环计划后 46 周。方法 60 名肥胖男性（年龄≥19 岁）（体脂百分比≥25%）被随机分配到干预组（n = 30）或对照组（n = 30），为期 12 周。干预组接受了每周三次的在线循环训练，而对照组接受了一个网站，帮助他们达到身体活动指南。在加入该计划 46 周后，使用心率追踪器 (Fitbit Charge 3) 和运动日志评估对每周身体活动指南的遵守情况。在基线以及 12、24 和 46 周后测量健康结果（例如人体测量、身体成分）。结果 干预组在 46 周时对体力活动指南的遵守率 (36.8%) 高于对照组 (5.3%；P = 0.02)。然而，在 12、24 和 46 周后，干预组参与者与对照组参与者之间的健康结果没有观察到差异。结论 提高肥胖男性锻炼的坚持性具有挑战性。拟议的计划在大约一年后提高了肥胖男性对身体活动指南的遵守率；然而，需要更多的研究来了解在该人群中进行在线分娩锻炼计划时如何改善健康结果。
