The purpose of this study was to examine the effects of vertical trunk supportability improvement on activities. The study participants were 36 people. Trunk function and physical performance were evaluated using the following tests: trunk righting test (TRT), maximal isometric knee extensor strength test, side hop test, triple hop distance test, stabilometry of one-leg standing, and one-leg rebound jump. The measurement was performed three times: pre-trunk training (pre), post-trunk training for 1 month (post), and 2 months after the second measurement (detraining). Details of trunk training: Two sets of 30-s maximal lateral reach exercises on each side, following the four sets of 15-s maximal raising trunk exercises on each side. The results with TRT in post-training were significantly larger than those in pre-and detraining. Similarly, the results with one-leg rebound jump efficiency in post-training were significantly larger than those in pre-and detraining. Our findings indicate that jump efficiency changes in proportion to the change in vertical trunk supportability.
本研究旨在探讨改善垂直躯干支撑能力对活动的影响。研究参与者为 36 人。使用以下测试评估躯干功能和身体表现:躯干翻身测试(TRT)、最大等长膝伸肌力量测试、侧跳测试、三跳测试、单腿站立稳定度测试和单腿反弹跳测试。测量进行了三次:在躯干训练前(pre)、躯干训练 1 个月后(post)和第二次测量后 2 个月(脱训)。躯干训练的详细信息:每侧进行两组 30 秒最大侧向伸展练习,然后进行四组每侧 15 秒最大抬高躯干练习。在训练后的 TRT 结果明显大于在预训练和脱训后的结果。同样,在训练后的单腿反弹跳效率结果明显大于在预训练和脱训后的结果。我们的发现表明,跳跃效率的变化与垂直躯干支撑能力的变化成正比。
