背景
本研究的目的是检查不同级别的团队手球运动员肩部旋转强度与球速度之间的关系。
方法
三组年轻健康的男性受试者参加了实验：一组由 15 名手球运动员（A1 联赛最佳得分手）组成，另一组由 12 名手球运动员（A2 联赛最佳得分手）和随机抽样的 15 名体育学生组成。每个受试者都在 Cybex II 等速测力计上进行了测试。以 60、180 和 300 度/秒的速度检查主肩部的内旋和外旋同心动作。通过三种类型的投掷来检查球的速度：(a) 原地投掷，(b) 交叉步，以及 (c) 垂直跳跃。使用皮尔逊积矩相关性和单向方差分析进行统计分析。
结果
三组内、外肩旋转峰值扭矩值差异无统计学意义。在所有类型的投掷中，各组之间的球速度差异具有统计学显着性（p<0.001）。除跳投外，肩部 IR 和 ER 旋转与球速度之间的关系没有统计学意义。
结论
这项研究的主要发现是，在所有受试者中，无论投掷能力如何，除了跳投外，肩部 IR 和 ER 的峰值扭矩都不能很好地反映任何类型投掷的投掷速度。
BACKGROUND
The purpose of this study was to examine the relationship between the rotational strength of shoulder and ball velocity in team handball players from various levels.
METHODS
Three groups of young healthy, male subjects took part in the experiments: one group of 15 handball players, the best of League A1 scorers, another group of 12 handball players, the best of League A2 scorers and a random sample of 15 physical education students. Each subject was tested on a Cybex II isokinetic dynamometer. The concentric action of the internal and external rotation of the dominant shoulder was examined at 60, 180 and 300 deg/sec. Ball velocity was examined in three types of throw: (a) on the spot, (b) with a cross-over step, and (c) with a vertical jump. Statistical analysis was performed using the Pearson product-moment correlation and one-way analysis of variance.
RESULTS
The differences of peak torque values of the internal and external shoulder rotation between the three groups were not statistically significant. The differences between groups regarding ball velocity in all types of throw were statistically significant (p<0.001). The relationship between IR and ER rotation of the shoulder and ball velocity was not statistically significant, except the jump shot.
CONCLUSIONS
The main finding of this study was that peak torque of IR and ER of the shoulder was not a good indicator of throwing velocity at any type of throw, except the jump shot, in all subjects, regardless of their throwing ability.
