Abstract：
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.
摘要：
这项研究的主要目的是测试肩内旋转强度与站立投掷速度之间的关系。对20名专业手球运动员进行了重复测量的横断面研究（平均值±SD；年龄：19.28±2.55岁，重量：81.52±9.66kg,身高：185±6厘米，BMI：23.74±1.69）。指示参与者以最大速度从手球场的7m线处进行8次站立投掷，以计算平均和最大投掷速度。进行增量测试以计算内部旋转肩部强度的重复最大值（1-RM）。采用95%置信区间(95%CI)的Pearson相关分析来确定优势臂内旋强度特征与最大和平均投球速度之间是否存在相关性。投掷肩的内部旋转强度与站立手球投掷中的球速度之间没有相关性。
