스쿠버 다이버의 수중체력과 기초체력의 상관 및 판별분석 = Correlation and Discriminant Analysis between Underwater Fitness and Physical Fitness of Scuba Divers

다국어 초록 (Multilingual Abstract)

[INTRODUCTION] The purpose of this study was to identify the relations between underwater fitness and physical fitness of scuba divers, to increase the physical fitness for scuba diving, and to prevent underwater emergency. [METHOD] The subjects were consisted of 20 divers who have diving experiences of 525±95.15times. The relationships between physical fitness factors and underwater fitness(240m underwater swimming times) were analyzed through correlation and discriminant analysis to identify the land based physical fitness factors which would support scuba diving fitness. [RESULT] Correlation analysis between underwater swimming time and physical fitness factors, 240m underwater swimming time have a negative correlations with muscle strength(grip, Lumbar stabilization 4 posture), cardiovascular endurance(maximal oxygen consumption), power(Sargent jump), agility(side step test) and body composition(BMI). However, 240m underwater swimming time have none significant negative correlations with muscular endurance(sit-ups), flexibility(sit and reach, shoulder flexibility), and balance(one leg standing). As a results of discriminant analysis, underwater swimming time groups were discriminated by physical fitness factors. [CONCLUSION] The exercise program include muscle strength, cardiovascular endurance, power and agility as well as body composition may enhance underwater fitness and assist diving ability of scuba divers.

[서론] 본 연구의 목적은 수중체력과 기초체력의 상관관계를 분석하여 수중체력과 상관이 있는 기초체력요인을 규명하고, 스쿠버 다이빙에서 필요한 체력적 요소의 향상과 수중 안전사고의 예방에 기여하는 데 있다. [방법] 잠수횟수가 525±95.15회이며, 스쿠버 자격증을 소지한 20명을 대상으로 하여, 240m 수중수영시간과 기초체력을 측정하고 상관분석과 판별분석을 실시하였다. [결과] 240m 수중수영시간과 기초체력의 상관분석을 실시한 결과, 240m 수중수영기록은 근력(악력, 요부 안정화 근력 4자세), 심폐지구력(최대산소섭취량), 순발력(Sargent jump), 민첩성(Side step test) 및 신체구성(BMI)과 유의한 상관이 나타났다. 그러나 근지구력(윗몸일으키기), 유연성(체전굴, 좌/우 어깨 유연성), 평형성(한발서기)과는 유의한 상관이 나타나지 않았다. 판별분석 결과 기초체력변인으로 수중수영속도 집단을 유의하게 판별하였다. [결론] 지상에서의 근력, 심폐지구력, 순발력 및 민첩성 등 복합적인 체력요소와 신체구성이 고려된 운동의 실시가 스쿠버 다이버의 수중체력과 스쿠버 다이빙 기능 향상에 도움을 줄 수 있을 것이다.
