The main objective of this study was to test the relationship between shoulder internal rotation strength and standing throwing velocity. A repeated measures cross-sectional study was conducted with 20 professional handball players (mean ± SD; age: 19.28 ± 2.55 years, weight: 81.52 ± 9.66 kg, height: 185 ± 6 cm, BMI: 23.74 ± 1.69). The participants were instructed to perform eight standing throws from the 7 m line of the handball court at maximum velocity to calculate the mean and maximum throwing velocity. An incremental test was performed to calculate the repetition maximum (1-RM) of internal rotation shoulder strength. A Pearson's correlation analysis with a 95% confidence interval (95% CI) was performed to determine whether correlations existed between dominant arm internal rotation strength characteristics and maximum and mean ball-throwing velocity. There is no correlation between the internal rotation strength of the throwing shoulder and the velocity of the ball in the standing handball throw.
本研究的主要目的是测试肩部内旋力量与站立投球速度之间的关系。采用重复测量的横截面研究方法，对 20 名职业手球运动员（均值±标准差；年龄：19.28±2.55 岁，体重：81.52±9.66 公斤，身高：185±6 厘米，BMI：23.74±1.69）进行了研究。参与者被要求从手球场的 7 米线以最大速度进行八次站立投球，以计算平均和最大投球速度。进行递增测试以计算内旋肩部力量的重复最大量（1-RM）。采用 Pearson 相关分析和 95%置信区间（95%CI）来确定优势臂内旋力量特征与最大和平均球投速度之间是否存在相关性。在站立式手球投掷中，投掷肩的内旋力量与球速之间没有相关性。
