Abstract:
To determine the effects of 10 weeks of weight training, 49 healthy men of Thai Naval Medical students between 18-20 year of age were randomly assigned to either weight training (N = 27) or control (N = 22) group. Despite no changes in maximal aerobic consumption (VO2max.), but significant increase in anaerobic threshold (AT), cycle time to exhausion at 95% VO2max., leg strength (one repetitive maximum), anaerobic power (AP), and aerobic capacity were observed following training (P<0.01, P<0.01, P<0.001, P<0.01, and P<0.01, respectively). No significant change in all parameter were observed in the control group. The improved cycle endurance performance was associated with increase in leg strength, AP, AC, and AT. (P<0.01) These finding indicated that weight training improve anaerobic performance and endurance performance. This improved cycle performance appears to be related to increase in AT, AP, AC, and leg strength.
