The purpose of the present study was to examine the effects of iron shot practice volume based on golf skill level on the indices of muscle damage and fatigue in blood. Twenty four golf players were studied under conditions of different golf skill level (beginners, intermediate, expert) and practice volume (100, 200, 300balls). In this study blood CK and LDH were determined to show thelevel of muscle damage, and blood phosphorus, lactate, and ammonia were measured to see the level of fatigue. Blood creatinine, and IGF-Ⅰ generally used to see the rate of protein synthesis were also measured. In summary, these results are interpreted to mean that 1) blood fatigue factors, muscle damages, and creatinine levels increased due to a rise in the practice volume of iron shot, 2) those levels decreased due to rise in the golf skill level, 3) blood fators and creatinine recovered quickly after exercise, however muscle damages did not recover even after 24hr. Therefore, both golf skill level and practice volume should be considered to prevent muscle damage and fatigue during practice iron shot.
