The purpose of this study was to investigate how abdominal and back exercises affect core strength and rowing performance of well-trained rowers. Seven subjects(experimental group) participated in six-week core training program and five subjects served as controls. Before and after the program, isokinetic abdominal and back strength, deadlift 1RM, sit-up test, and 2,000m rowing time were measured. The results were as follows. After six-week core training program, experimental group showed significant improvements in abdominal isokinetic muscle strength(p<.01) at 30°/sec, 60°/sec angular velocity and muscle endurance(p<.001) at 120°/sec angular velocity. However, there were no changes in back isokinetic muscle strength and endurance. Experimental group also showed improvements in deadlift 1RM and sit-up test after core training(p<.05). Despite improvements in abdominal muscle strength and endurance, there was no changes in 2,000m rowing time. It was concluded that six-week core training program improved abdominal isokinetic muscle strength and endurance but it had no positive effects on rowing performance of well-trained rowers.
