This study investigated the effect of a softball training for muscular strength, muscle power and agility of collegiate softball players during the regular season. Nine female softball players volunteered to participate in this program 4 times a week for 16 weeks. Grip strength, back strength, isometric force of knee extension, isokinetic arm and leg extension power, whole-body reaction time, simple reaction time, and specific bat swing reaction time were measured before and after 16 weeks of training. The training significantly increased isometric force of knee extension (24.0%, P<0.05), isokinetic arm extension power at 80 cm/sec (27.2%, P<0.05), isokinetic leg extension power at 120 cm/sec (22.1%, P<0.05) and bat swing choice reaction time (9.4%, P<0.05). On the other hand, grip strength, back strength, arm extension power at 20 cm/sec and 120 cm/sec, leg extension power at 20 cm/sec and 80 cm/sec, and whole-body and simple reaction time were unchanged significantly. These results indicate that the regular-season softball training was effective for isometric knee extension strength, isokinetic arm extension power at 80 cm/sec and leg extension power at 120 cm/sec, and bat swing choice reaction time.
