Abstract

The purpose of this research was to investigate how the plyometric training and weight training program, applied in the field for exercise performance of throwing players, influenced improvement of athletic abilities, including agility, maximum muscular power, and strength. After implementing plyometric training and weight training to 21 high school throwing players for 10 weeks, we designed the next step. The 21 subjects were divided into two groups - women's group and men's group. All subjects were tested to determine agility using sidestep, burpee test, reaction time, lower body power and strength using standing long jump, standing jump, 30 m running, squats and leg presses. Additionally, isokinetic strength was measured using Cybex isokinetic dynamometer. The results showed that both groups demonstrated improvement in the standing long jump, standing jump and 30 m running after training. Particularly, the women's group indicated better improvement. Second, women's groups showed higher improvement in the sidestep and burpee test. However, in the reaction time test, the men's group indicated better improvement. Third, both groups showed better improvement in squats and leg presses after training. Particularly, the women's group indicated better improvement. Fourth, in the left and right side extension torque and flexion torque at a velocity of $60^{\circ}$/sec, both groups showed better improvement after training. In the left side extension peak torque, the men's group showed higher improvement, but the women's group showed higher improvement in the left side flexion and extension peak torque. Fifth, both groups showed better improvement in bench pressing and back strength after training. Particularly, the women's group indicated higher improvement.

본 연구는 육상 투척선수들의 plometric training과 weight training 프로그램 훈련이 순발력 및 민첩성과 최대 근력의 운동능력 향상에 어떠한 영향을 가져오는지 검증하기 위하여 고등학교 재학 중인 투척선수 21명을 대상으로 plyometric training과 weight training을 10주간의 트레이닝을 실시하여 여자 집단(10명)과 남자 집단(11명)으로 분류하여 다음과 같은 결론을 얻었다. 순발력에 있어서 제자리멀리뛰기, 서전트 점프, 30 m 달리기는 트레이닝 전에 비해 두 집단 모두 향상도를 보였으며, 여자 집단이 더 높은 향상도를 나타냈다. 민첩성에 있어서 사이드스텝, 버피 스텝, 전신반응 테스트는 트레이닝 전에 비해 모두 향상도를 보였으며, 사이드스텝과 버피 스텝은 여자 집단이 더 높은 향상도를 나타냈으며, 전신반응 테스트는 남자 집단이 더 높은 향상도를 나타냈다. 하지 근력에 있어서 squat, leg press는 트레이닝 전에 비해 모두 향상도를 보였으며, 여자 집단이 더 높은 향상도를 나타냈다. 무릎 관절 등속성 근력에 있어서 왼쪽, 오른쪽 신근력과 굴근력은 트레이닝 전에 비해 모두 향상도를 보였으며, 왼쪽 신근력은 남자 집단이 더 높은 향상도를 나타냈으며, 왼쪽 굴근력, 오른쪽 신근력, 오른쪽 굴근력은 여자 집단이 더 높은 향상도를 나타냈다. 상지의 근력에 있어서 Bench press, 배근력은 트레이닝전에 비해 모두 향상도를 보였으며, 여자집단이 더 높은 향상도를 나타냈다.
