Exploration of the Shoulder Internal Rotation’s Influence on Throwing Velocity in Handball Players: A Pilot Study García Buendía, Gustavo Martínez García, Dario Jerez Mayorga, Daniel Alejandro Chirosa Ríos, Ignacio Jesús Chirosa Ríos, Luis Javier Internal rotation Throwing velocity Shoulder strength Dynamometry Athletic performance Handball 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. 2023-01-23T09:02:48Z 2023-01-23T09:02:48Z 2022-11-29 journal article García-Buendía, G...
