본 연구에서는 남자 실업팀 핸드볼 선수들을 대상으로 플라이휠 운동을 적용한 웨이트 트레이 닝 프로그램을 개발하여 상해예방과 경기력 향상을 위한 기초자료를 제공하는데 그 목적이 있다. 12주간 복합 플라이휠 운동 프로그램을 적용하여 신체조성, 체력요인, 무산소성파워, 등속성근기능에 미치는 영향 을 분석한 결과는 다음과 같다. 팔굽혀펴기는 그룹 간 유의한 차이가 나타났다. 체지방률, 무산소성 파워는 시기별 상호작용에서 유의한 차이가 나타났다. 제자리멀리뛰기, 제자리높이뛰기, 악력, 배근력, 무산소성평 균파워 그리고 등속성근기능검사는 좌굴근과 우굴근에서 시기별로 유의한 차이가 나타났다. 따라서 12주 간 플라이휠 운동을 활용한 웨이트 트레이닝 결과는 상해예방과 경기력 향상을 위한 기초자료로 제공할 수 있을 것으로 판단된다.

The objective of this study is to investigate the relationship between anaerobic・aerobic exercise intensity and hand steadiness. Based on physiological analysis the conceptual model explaining that both increased anaerobic and aerobic exercise intensity reduce hand steadiness is suggested, which is verified through the experiment with 20 subjects. Hand steadiness is the critical contributor to having an effect on the job performance just as in the rifle shooting and archery in sports, and the microscope-related job requiring hand steadiness in industries, and so forth. In anaerobic exercise experiment the hand steadiness is measured through hand steadiness tester having 9 different diameter holes after each subject exerts 25%, 50%, 75%, and 100% of maximum back strength measured by back muscle dynamometer. In aerobic exercise condition after they do jumping jack, it is evaluated at each time heart rate reaches 115%, 130%, and 145% of reference heart rate measured in no exercise. The findings are that an increased intensity in both types of exercises tend to decrease hand steadiness, but hand steadiness at 25% of maximum back strength and 115% of reference heart rate is rather higher than at no exercise. Just as the association between cognitive stress and job performance has upside-down U form, so does the relation of physical loading to hand steadiness, which means that a little exercise has a tendency to improve hand steadiness compared to one in no exercise condition .
