Muscle strength and mass strongly influence performance. The role of the trunk, upper limbs, and lower limbs in a specific performance is important but unclear in terms of muscle strength, muscle mass, and the degree of influence of each part. Standing long jump is a performance that produces results by not only the muscles of the lower limbs working together but also the entire body, including the trunk and upper limbs. To determine the influence of muscle strength and the mass of each body part on standing long jump, 31 healthy young adults (18 males and 13 females) participated in this study. Abdominal trunk muscle strength, grip strength, and knee extension muscle strength were measured, each of which was defined as trunk, upper limb, and lower limb muscle strength. The trunk, upper limb, and lower limb muscle masses were measured using a body composition analyzer. Performance was measured using the standing long jump test (jumping power). Factors influencing standing long jump were examined. A multiple regression analysis revealed that trunk (β = 0.367, = 0.006) and upper limb (β = 0.608, < 0.001) muscle strength values were extracted for standing long jump (adjusted R = 0.574, < 0.01). Trunk and upper limb muscle strength influence standing long jumps.
肌肉力量和肌肉量对运动表现有很大影响。在特定运动表现中，躯干、上肢和下肢的作用很重要，但在肌肉力量、肌肉量以及各部位的影响程度方面尚不清楚。立定跳远是一项不仅需要下肢肌肉协同工作，还需要包括躯干和上肢在内的整个身体参与才能产生结果的运动。为了确定身体各部位的肌肉力量和肌肉量对立定跳远的影响，31名健康的年轻成年人（18名男性和13名女性）参与了本研究。测量了腹部躯干肌肉力量、握力和膝关节伸展肌肉力量，分别将其定义为躯干、上肢和下肢肌肉力量。使用身体成分分析仪测量了躯干、上肢和下肢的肌肉量。通过立定跳远测试（跳跃力）来测量运动表现。研究了影响立定跳远的因素。多元回归分析显示，立定跳远提取了躯干（β = 0.367，P = 0.006）和上肢（β = 0.608，P < 0.001）的肌肉力量值（调整R = 0.574，P < 0.01）。躯干和上肢肌肉力量影响立定跳远。
