Can post-activation potentiation induced by high-intensity dynamic and static kinetotherapies enhance muscle explosive power? / 中国组织工程研究

ABSTRACT

BACKGROUND: Increasing evidence has shown that high-intensity warming up, including dynamic and static kinetotherapies, can improve the performance of muscle explosive power. However, the training scheme to achieve the best effect remains unclear. OBJECTIVE: To discuss whether the high-intensity dynamic and static kinetotherapies can enhance post-activation potentiation of the upper and lower limbs, so as to fully understand the high-intensity warming up, and thus promote the training efficacy. METHODS: Ovid Medline, Elsevier SDOL, PubMed, and CBJ databases were retrieved for the articles addressing the post-activation potentiation of high-intensity dynamic and static kinetotherapies published before 2016. The articles were classified in accordance with Oxford Centre for Evidence-based Medicine Levels of Evidence. RESULTS AND CONCLUSION: The possible mechanisms of the post-activation potentiation include the phosphorylation of myosin regulation light chain, the increase in motor unit recruitment as well as the change of pinnate angle. The resistance exercise at an appropriate mode, including dynamic, static, and dynamic combined with static, significantly induces post-activation potentiation, and improves the explosive force. Post-activation potentiation is impacted by muscle contraction type, amount of exercise, exercise intensity, induction time, and history of the subjects (training experience, absolute muscle force, and muscle fiber composition). High-intensity stimulus of post-activation potentiation may be accompanied by the generation of fatigue, and the inappropriate recovery time may result in the imperfect performance of post-activation potentiation.
