This study aimed to examine the effects of supervised fitness training under the guidance of a personal trainer and those of competitive fitness training with others and reveal the effects of specific differences between them in a detailed manner. The study's participants consisted of 66 healthy male adults (age: 29.2 ± 5.4 years). The participants were divided into three groups: the individual training group (n = 21), which served as the control group; the exercising with a partner group (n = 22); and the group trained by a personal trainer (n = 23). Each participant was subsequently assessed using one repetition maximum bench press, squats, skeletal muscle mass, fat mass, and a questionnaire regarding nutritional plan and injury to compare the effects of training sessions over a period of 12 weeks. Among the three groups, only the group trained by a personal trainer showed an obvious enhancement in fat reduction compared to baseline (-1.61 kg, = 0.033), which was suggestive of a salient trend that far surpassed those of the individual training group and the exercising with a partner group. Regarding squats, only the group trained by a personal trainer showed a significant change compared to the individual training group ( = 0.003). Regarding the participants' consistent use of a nutritional plan, only the group trained by a personal trainer exhibited a palpable tendency ( < 0.001); furthermore, the effect of preventing injury in the group trained by a personal trainer was more notable than that in the individual training group and the exercising with a partner group. Our results indicate that a fitness personal trainer service is effective in expediting the process of achieving fitness goals in a relatively safe manner, thereby substantiating the diversified values of the fitness personal trainer service.
本研究旨在考察在私人教练指导下的监督式健身训练以及与他人进行的竞争性健身训练的效果，并详细揭示两者之间的具体差异所产生的影响。该研究的参与者包括66名健康成年男性（年龄：29.2±5.4岁）。参与者被分为三组：作为对照组的个人训练组（n = 21）；结伴锻炼组（n = 22）；以及私人教练指导组（n = 23）。随后，对每位参与者进行一次最大重复卧推、深蹲、骨骼肌质量、脂肪量评估，并就营养计划和损伤情况进行问卷调查，以比较12周训练期的训练效果。在这三组中，与基线相比，只有私人教练指导组的脂肪减少情况有明显改善（-1.61千克，P = 0.033），这表明其显著趋势远远超过个人训练组和结伴锻炼组。关于深蹲，与个人训练组相比，只有私人教练指导组有显著变化（P = 0.003）。关于参与者对营养计划的持续使用情况，只有私人教练指导组呈现出明显趋势（P < 0.001）；此外，私人教练指导组在预防损伤方面的效果比个人训练组和结伴锻炼组更显著。我们的结果表明，健身私人教练服务能够以相对安全的方式有效加速实现健身目标的进程，从而证实了健身私人教练服务的多元价值。
