Online exercise is undoubtedly useful and important; however, chronic adaptations to online exercise, particularly strength gain, muscle hypertrophy, and cardiovascular parameters, remain unclear. We investigated the effect of online exercise training using Zoom on fitness parameters compared with the same exercises supervised directly. In the present study, 34 subjects (age: 42.9±14.4 years) were included. Twenty-three subjects performed 8 weeks of body mass-based exercise training online using Zoom, and eleven subjects performed the same exercise supervised directly as the control group. The subjects performed low-load resistance exercises twice a week for 8 weeks for a total of 16 sessions. The sessions included 9 exercises: leg raises, squats, rear raises, shoulder presses, rowing, dips, lunges, Romanian dead lifts, and push-ups. Chair-stand, push-up, and sit-and-reach tests were performed on all subjects. Overall, the home exercise program effectively increased strength and muscle mass and decreased blood pressure and arterial stiffness, but there were no differences between the groups. Changes in chair-stand and sit-and-reach test results were higher in the control group than in the online group. Our results show that there is a similar training response to body mass-based training in both groups, even with virtual experiences using Zoom.
在线锻炼无疑是有用且重要的；然而，对在线锻炼的长期适应性，尤其是力量增长、肌肉肥大和心血管参数，仍不明确。我们研究了使用Zoom进行在线锻炼训练对健康参数的影响，并与直接监督下进行相同锻炼的情况作比较。在本研究中，纳入了34名受试者（年龄：42.9±14.4岁）。23名受试者使用Zoom在线进行了为期8周的基于体重的锻炼训练，11名受试者作为对照组在直接监督下进行相同锻炼。受试者每周进行两次低负荷阻力锻炼，共进行8周，总计16节课程。这些课程包括9项锻炼：抬腿、深蹲、后抬腿、肩推、划船、俯卧撑、弓步蹲、罗马尼亚硬拉和俯卧撑。对所有受试者进行了椅子站立、俯卧撑和坐位体前屈测试。总体而言，家庭锻炼计划有效增强了力量和肌肉量，并降低了血压和动脉僵硬度，但两组之间没有差异。对照组椅子站立和坐位体前屈测试结果的变化高于在线组。我们的结果表明，即使是通过使用Zoom的虚拟体验，两组对基于体重的训练也有相似的训练反应。
