Muscle strength data for sports which have varying demands on the trunk musculature are needed. The purpose of this study was to measure the trunk strength of three different sports groups of male varsity athletes and a recreationally active but nontrained group. Forty-six athletes (soccer: N = 16, Canadian football: N = 15, and middle and long distance runners: N = 15) and 15 recreationally active subjects were studied. Three consecutive concentric and eccentric contractions through a range of 60 degrees at an angular velocity of 30 degrees per second (0.5236 rad/sec) were performed to measure the strength of the trunk flexors and extensors. Results showed peak concentric and eccentric flexor torque for football and soccer players to be significantly greater than the other two groups (p < or = 0.05). Peak concentric and eccentric extensor torque was significantly greater for football players than runners (p < or = 0.05). Soccer players' eccentric flexor peak torque relative to body mass was significantly greater than runners and the recreationally active subjects (p < or = 0.05). This study compares trunk flexor and extensor data for specific sports populations.
我们需要针对对躯干肌肉组织有不同要求的运动项目收集肌肉力量数据。本研究的目的是测量三组不同的男性大学运动员以及一组有运动习惯但未经训练的人群的躯干力量。我们对46名运动员（足球运动员：N = 16，加拿大橄榄球运动员：N = 15，中长跑运动员：N = 15）和15名有运动习惯的受试者进行了研究。通过以每秒30度（0.5236弧度/秒）的角速度在60度范围内进行三次连续的向心和离心收缩，来测量躯干屈肌和伸肌的力量。结果显示，橄榄球和足球运动员的向心和离心屈肌峰值扭矩显著高于其他两组（p≤0.05）。橄榄球运动员的向心和离心伸肌峰值扭矩显著高于跑步运动员（p≤0.05）。足球运动员相对于体重的离心屈肌峰值扭矩显著高于跑步运动员和有运动习惯的受试者（p≤0.05）。本研究比较了特定运动人群的躯干屈肌和伸肌数据。
