速度依準方式在阻力訓練上的應用與效益

With the popularity of resistance training, setting the training intensity and volume by safe and effective method has become an important issue for coaches and players. Therefore, using new technology equipment to improve the efficiency is the new trends in training. Recent researches applied the linear position transducers to monitor the movement velocity during resistance training, which was called velocity-based resistance training (VBRT). Studies indicated that VBRT can provide immediate feedback to the coaches and players and enhance the training effects. VBRT also can be applied to establish load-velocity relationship to conduct individual training program. This review summarized the theory and application of VBRT. The review indicated that performing 2-3 times per week for 6-8 weeks of VBRT would have more training benefits. Conducting bench press with mean propulsive velocity (MVP) at 0.47 m/s (~80% 1-RM) to 0.79 m/s (~60% 1-RM) could improve the maximal muscular strength of upper limb, MPV of squat at 0.68 m/s (~80% 1-RM) to 0.98 m/s (~60% 1-RM) could enhance maximal muscular strength of lower limb, and MPV of squat at 1.06 m/s (~58% 1-RM) to 1.2 m/s (~45% 1-RM) could elevate the power of lower limb. Moreover, stopping the training when MPV loss reached 20% within the set is a more effective method for improving strength and power of lower limb.
