Abstract :This study aimed to investigate the effect of the isokinetic shoulder strength on the phases of speed performance. The study included 45 male participants who were athletes or had a sports background. The mean age of the participants was 19.64±2.02 years, the mean height was 175.11±14.54 cm, the mean body weight was 68.44±5.96 kg, and the mean sports age was 5.40±3.90 years. In the study, data on the isokinetic shoulder strength and phases of speed were collected. A 100-meter sprint test was used to evaluate the phases of speed, and a Cybex Humac Norm 2004 device was used to determine the isokinetic shoulder strength. In light of the results obtained, left shoulder extension peak torque (left SEPT) and left shoulder flexion peak torque (left SFPT) values were found to affect all phases of speed except reaction speed, while right shoulder extension peak torque (right SEPT) values were found to affect only reaction speed and middle acceleration phase. Furthermore, right shoulder flexion peak torque (right SFPT) values were found to affect all speed phases except early acceleration and the transition phase. In general, the isokinetic shoulder strength was found to affect all phases of speed, with the highest effect level in the maximum speed and in the continuity phases of speed. In conclusion, the isokinetic shoulder strength is thought to have a significant effect on overall speed performance. The isokinetic shoulder strength has the most effect, especially in the maximum speed and speed continuity phases. Shoulder strength should be taken into consideration when organizing the training programs of athletes in all sports branches that include short- or long-distance speed performance.
