ABSTRACT

한국어 초록

모든 스포츠 경기는 경기력에 미치는 영향 요인으로 체력과 기술, 정신력 등으로 분류할 수 있다. 특히 체력은 모든 경기수행의 질과 관련된 기술이나 전략을 수행하는데 있어서 기본 바탕이 될 수 있으므로 경기력 향상을 위해 가장 선행되어져야 하는 필수적인 요소이다. 이러한 체력의 요소 중 기술력과 밀접하게 관련된 요소는 근력이라고 할 수 있는데 특히 배구 경기는 빠른 신체이동과 높은 점프능력이 요구되며 완벽한 공격과 수비를 위해서는 하체와 어깨근력의 효율성이 경기

영어 초록

The purpose of this paper was to compare the isokinetic muscular strengths, endurance, and power of thigh and shoulder between volleyball players and elementary school boys. The isokinetic strength was investigated by using isokinetic dynamometer(Cybex 770, NormTM Test & Rehabilitation, USA). For measuring the peak torque, muscle power, and muscular endurance, extension and flexion forces of knee and shoulder joints with both right and left sides were measured at the angle speed of 60°/sec(4 repetitions), 180°/sec(4 repetitions), and 240°/sec(5 repetitions), respectively. The mean and standard deviation are evaluated over the data measured by using SPSS program, and Independent t-test was used for validating the mean difference between each variables. The level of significance was set as α = 0.05. The thigh strength and power in extension and flexion were not significantly different between volleyball players and elementary boys, respectively. However, the thigh endurance of extension and flexion in volleyball players was significantly greater than in elementary boys (p < 0.05). The shoulder extension strength and power in the volleyball players was significantly greater than in elementary boys(p < 0.05). Also, the shoulder extension and flexion endurances in volleyball players were greater than in elementary boys(p < 0.05). Therefore, the recreational volleyball activity in elementary school might be recommended to enhance the fitness-related muscular endurance
