This study was conducted on elite bodybuilders for 6 weeks using two weight loss methods (traditional method=high-weight loss vs. new method=low-weight loss). The subjects of this study were 26 male active elite bodybuilders who voluntarily wanted to participate in this experiment, and were divided into experimental group and traditional group. The traditional and experimental groups underwent dietary restrictions and training for 6 weeks. The conclusion obtained from the results of this study is that in the case of anthropometric variables, there is a difference in weight class between the two groups. The experimental group's upper arm circumference was maintained compared to the pre-measured value after post-measurement, while the traditional group decreased, and a significant interaction effect was observed. In particular, a significant interaction effect was observed. In that the absolute value of maximum oxygen intake was significantly increased only in the post-experimental group compared to the pretest, and an interaction effect was observed, the use of low-weight loss method is more effective than the traditional method of high-weight loss method. An increase in some cytokines was observed despite traditional weight loss, but it did not cause an excessive decrease in immunity or a sharp decrease in performance factors. As a result of this experiment, it is judged that the use of a low-weight loss method is more preferable than the traditional high-weight loss method in relation to performance variables.
本研究以精英健美运动员为对象，采用两种减肥方法（传统方法 = 高体重减轻 vs. 新方法 = 低体重减轻）进行了为期6周的研究。本研究的对象是26名自愿参加本实验的男性现役精英健美运动员，分为实验组和传统组。传统组和实验组都进行了6周的饮食限制和训练。从本研究结果得出的结论是，在人体测量变量方面，两组之间的体重等级存在差异。实验组在测量后上臂围与测量前相比保持不变，而传统组则下降，并且观察到显著的交互作用。特别是，观察到显著的交互作用。即与测试前相比，仅实验组的最大摄氧量绝对值显著增加，并且观察到交互作用，使用低体重减轻方法比传统的高体重减轻方法更有效。尽管采用传统减肥方法，但观察到一些细胞因子增加，但这并未导致免疫力过度下降或性能因素急剧下降。作为本实验的结果，判断在性能变量方面，使用低体重减轻方法比传统的高体重减轻方法更可取。
