The aim of this study was to identify the features of isokinetic shoulder and trunk muscle strength of volleyball attackers with shoulder problems and to compare them with those of baseball pitchers.18 competitive high school volleyball attackers and 16 competitive high school baseball pitchers were studied.6 of the attackers and 7 of the pitchers were suffering from shoulder pain but the other players had no history of shoulder pain. The tests were conducted using a Biodex system 3 multi-joint dynamometer. The shoulders were tested for their flexion and extension muscle strength on the scapula plane and trunk muscle strength were tested for their flexion, extension and torso-rotational strengths. The results were compared between the normal group (N-G)and the shoulder injured group (S-G) and also between the attackers and the pitchers. We observed weakness of shoulder flexion strength in S-G of both athletes and the flexion to extension muscle strength ratio was significantly lower in S-G of the attackers. We also noticed the decline of trunk torso rotation to shoulder extension muscle strength ratio in the same group. In comparisons between the attackers and pitchers of N-G, trunk flexion to extension muscle strength ratio of attackers was significantly higher. The reason of the above results, we assumed that the force created from lower extremities was used for jumping in volleyball, while in baseball, it is used for pitching. We also considered that force required for spiking is created from the trunk in volleyball. Characteristics of shoulder muscle strength as dynamic stabilizer are similar in both volleyball and baseball. Appropriate proximal kinetic chain rehabilitation for the leg, hip and trunk should be selected in accordance with the characteristics of sports activities to prevent shoulder injuries. Especially for volleyball attackers, trunk muscle training is a prerequisite to prevent shoulder injuries.

This report showed that the analysis of the isokinetic strength test for throwing shoulder injuries could be used to determine the appropriate time for the patient to return to pitching. During the last six years, among two hundred sixtyfive players studied, one hundred fifty high school baseball players were found to be uninjured while one hundred fifteen players were found to be suffering from throwing shoulder injuries. The tests were carried out using a CybexR II Multi-Joint Dynamometer. The patients were seated with their shoulders abducted at 90 degrees and their elbows flexed at 90degrees. The shoulders were tested for their rotational strength. We observed an imbalance of isokinetic strength of the shoulder by noticing a difference between the internal and external rotational strengths. In addition, we examined the data of concentric isokinetic endurance strength that had not been reported previously. Returning to pitching was found to be highly possible when the patients corrected the imbalance of internal and external rotational strengths and their concentric isokinetic endurance strength was above 70% measured by the concentric endurance strength test. Correction of the imbalance of internal and external rotational strengths and the improvement of endurance strength were considered to be necessary to judge the appropriate time for returning to pitching.
