PURPOSE This study investigated the correlation between anaerobic power and maximum muscle strength in relation to core muscle strength among Korean national golfers. METHODS A total of 96 national golfers (53 females and 43 males) participated in the study. Body composition was assessed using multi-frequency impedance devices, while core and lower extremity muscle strength (extension, flexion, flex/ex ratio) was measured using isokinetic strength tests. Anaerobic power was evaluated through peak power, average power, and power drop rate tests conducted on bicycle ergometers, along with one-repetition maximum (1RM) tests for squats and bench presses. Mean and standard deviation values were calculated for all variables, and linear regression analysis was performed to verify correlations, with statistical significance set at α=.05. RESULTS The comparison of physical characteristics between male and female national golfers revealed significant differences in age, height, body fat percentage, lean body mass, and weight. There was a strong correlation between core muscle strength and isokinetic lower extremity muscle strength. Additionally, a strong correlation was observed between core muscle strength and anaerobic power and between peak power and average power. Furthermore, there was a high correlation between core muscle strength and bench press and squat maximum muscle strength. CONCLUSIONS This study highlights the correlation between various professional physical fitness variables of Korean national golfers over the past decade. The findings are expected to provide valuable insights for coaches and players in developing future training programs.
