| 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. |
