It’s possible to evaluate the hemodynamics to observe the underlying physiological benefit. Previous studies indicated that the benefits of athletic performance in healthy young subjects were identical. However, there is no study combined aerobic interval training with alternately velocity resistance training to investigate hemodynamic and athletic performance. In addition, the amount of interval training in previous studies was not consistant. Subjects were 36 healthy men, age 20-30 and were randomly split into interval training (IT) and continuous training (CT) group. All subjects underwent 6 weeks training period, 5 times/wk, which consist of 3 times bicycle aerobic training (30min) and 2 time isokinetic resistance training (6-8 sets). The intensity of bicycle training in IT group is 40% and 80% V̇O2max alternately, 60% V̇O2max in the CT group. IT group performed 60° and 180° angular velocities alternately and CT group performed 120° in isokinetic resistance training program. Training volume is equal in both groups. The results showed that the maximal workload and the V̇O2max of anaerobic threshold increased significantly in both groups. In addition, the V̇O2max of IT group increased higher than CT group (17.7% vs 14.1%), and the maximal workload also higher than the CT group (19.6% vs 14.2%). In addition, IT group significantly enhanced O2Hb and THb of muscle during AT and peak exercise. The hemodynamics showed no significant change in the CT group. The results of this study showed that IT has similar or better effect than CT on athletic performance. Moreover, IT enhanced the muscle hemodynamics in healthy men. The results provide insights in training for healthy men.
