力量练习启动延迟性增强效应的基本原则及应用

Basic Principles and Application of Delayed Potentiation of Resistance priming exercise

当前,急性提高运动能力采用的一个策略是进行短时力量练习,运动负荷为最大力量或接近最大力量。这一现象称为运动后激活效应,可改善48h内各种神经肌肉性能的指标。因此,在赛前进行此类练习对于力量和爆发力类运动项目而言可能是一种有效的策略。目前确定了力量负荷和运动量等参数,但这些变量尚未得到全面的研究。此外,尚不清楚力量练习启动效应的最佳训练刺激。进一步研究力量练习启动效应对运动能力表现的影响,有助于在实际应用。

One strategy to acutely enhance performance involves completing short-duration maximal or near-maximal resistance exercise.This has been termed postactivation potentiation.Which can improve various measures of neuromuscular performance within 48 h and,therefore,performing this type of session prior to competition may be an effective performance strategy for strength and power sports.At present,although parameters such as resistance loading and exercise volume have been determined,these variables have not been fully studied.Therefore,the optimal training stimulus for the initiation effect of strength exercises is unknown.Further research on the effect of the strength exercise starting effect on specific indicators of athletic performance is helpful for practical applications.
