Virtual personal training might represent an uncomplicated, accessible, and time-efficient approach to supervised strength training, particularly under government-imposed lockdown or closure of fitness facilities. However, there appears a dearth of literature evaluating the efficacy of virtual personal training.
The present project considered two studies considering supervised virtual strength training. Study 1 considered trained participants being supervised one-to-one through traditional resistance exercise sessions in a strength training studio (STUD), compared to a virtual personal training protocol performed using bodyweight resistance exercises (VIRT). This study utilized a crossover design whereby male (n = 13) and female (n = 7) participants were tested for body composition using BodPod, and strength for bench press, leg press, and high-row exercises. Participants were then randomly assigned to 3-weeks of VIRT or 3-weeks of STUD training. Following each 3-week training period, participants had a 1-week period without training whereby mid-intervention testing occurred, after which participants then completed the alternate training intervention. For study 2, we surveyed the client base of a chain of training facilities that had begun offering virtual personal training during lockdown to explore their views on this approach.
Strength and body composition changes were similar between groups, however for neither condition did results surpass the smallest meaningful change. The remaining survey data suggests that supervised virtual resistance training yields similar perceptions of effort, motivation, enjoyment, and supervision quality, compared to traditional supervised studio training.
Based on the current data, it appears that short-term supervised virtual resistance training is as efficacious as traditional supervised studio-based resistance training.
虚拟个人训练可能是一种简单、便捷且高效的监督式力量训练方法，特别是在政府强制封锁或健身设施关闭的情况下。然而，评估虚拟个人训练效果的文献似乎很少。
本项目考虑了两项关于监督式虚拟力量训练的研究。研究1将在力量训练工作室（STUD）通过传统抗阻训练课程进行一对一监督的训练参与者，与使用自重抗阻训练进行的虚拟个人训练方案（VIRT）进行比较。本研究采用交叉设计，通过BodPod对13名男性和7名女性参与者进行身体成分测试，并对卧推、腿举和高位下拉练习的力量进行测试。然后将参与者随机分配到为期3周的VIRT训练或为期3周的STUD训练。在每个为期3周的训练期后，参与者有1周的无训练期，在此期间进行中期干预测试，之后参与者完成另一种训练干预。对于研究2，我们调查了一家在封锁期间开始提供虚拟个人训练的连锁训练机构的客户群体，以探讨他们对这种方法的看法。
两组之间的力量和身体成分变化相似，但在两种情况下，结果都未超过最小有意义变化。其余调查数据表明，与传统的监督式工作室训练相比，监督式虚拟抗阻训练在努力程度、动力、享受程度和监督质量方面产生了相似的感受。
根据目前的数据，短期监督式虚拟抗阻训练似乎与传统的基于工作室的监督式抗阻训练同样有效。
