This study aimed to present a comparative analysis of physical and fitness characteristics of adolescent baseball players by measuring the body composition, basic physical fitness, isokinetic muscle function of the lower extremities, and anaerobic power according to positions. A total of 21 adolescent elite baseball players (age: 16.1±1.1) were recruited and separated to pitchers (n=10), infield players (n=12), outfield players (n=14), and catchers (n=8). Body composition, basic physical fitness, lower limb isokinetic muscle function, and anaerobic power were analyzed. As a result, the weight, body mass index, and body fat mass of catcher were higher than those of other positions. On the other hand, basic physical fitness such as grip strength, back strength, sergeant jump, side step, and reaction time did not show any difference by position. In lower limb isokinetic muscle function, the extensor strength standardized to body weight and height was higher in catchers than in infield and outfield players, and the flexor strength in pitchers was higher than that of infield players. There was no difference in isokinetic muscular endurance in the extensors, but it was significantly higher in pitchers than infield players and outfield players in the flexors. In addition, the peak power and average power measured by anaerobic power were higher for pitchers than for infield players, and the fatigue index for catchers was higher than that of other positions. Therefore, factors such as body composition, lower limb isokinetic muscle function, and anaerobic power of adolescent baseball players showed differences, indicating the different physical characteristics according to positions.
