Comparison of Isokinetic Strength of Knee and Pulmonary Function between Collegians and Hockey Players in College

ABSTRACT

OBJECTIVE: The purpose of this study was to examine the strength of the knee and pulmonary function comparing collegians and hockey players in college. METHOD: KINdegreeCOM isokinetic dynamometer and medigraph were used to evaluate strength of the right lower extremity and pulmonary function to 30 male students comprising 15 hockey players and 15 collegians with no significant difference in age, weight, and height between the two groups. All subjects used their right lower limb as dominant limb. RESULTS: 1) The significant differences between collegians and hockey players were found in the peak torque at 60o/sec,180o/sec. 2) The siginficant differences between collegians and hockey players were found in forced vital capacity, forced expiratory volume in one second and expiratory reserve volume on the pulmonary function. 3) The significant correlation between isokinetic strength and pulmonary function were found in peak torque. CONCLUSION: It is turned out that hockey players in college have much better isokinetic strength and pulmonary function than collegians, so it is suggested this result have to be considered in selecting hockey players and exercise prescription.
