Introduction: This study was designed to investigate the relationships between performance and physical characteristics, physical fitness, and isokinetic strength in the professional baseball hitter. Subjects were 22 pro-baseball hitters.
Method: Physical characteristics were estimated by age, height, weight, and %body fat. Physical fitness was estimated by flexibility, power, whole body reaction time and cardiorespiratory function. Isokinekic strength was estimated by shoulder, lumbar and knee joint.
Result: The results showed that hittng average was significantly correlation between career(r=.461*), flexibility(r=.439*). The slugging average had significantly correlation between weight(r=.513*), career(r=.460*), flexibility(r=.549**). The home run had significantly correlation between age(r=.440*), weight(r=.482*), power(r=.573**), right shoulder external rotation(r=.473*), left internal rotation(r=.443*, r=.515*), left knee flexion(r=.434*). The three-base hit had significantly correlation between power(r=.598*). The two-base hit had significantly correlation between power(r=.605*), right knee flexion(r=.479*).
Conclusion: First, There was significant relationship among hitting factor and career and body weight and age. Second, There was significant relationship among hitting factor and flexibility and power. Third, There was significant relationship between Right, left shoulder joint Rotation and hitting factor. fourth, There was significant relationship between Right, left knee joint and hitting factor. To enhance the performance, training object of hitter should be established that increase lean body mass, management body weight, power, flexibility, and muscle strength, muscle power of shoulder and knee joint.
