Twelve experienced male weight lifters of varying ability completed a series of bench press lifts at 95% of maximum. These lifts included a rebound bench press, which was performed without a delay between the downward and upward components of the lift, a bench press performed without a downward phase, and two bench press movements performed with various pause periods imposed between the downward and upward phases of the lift. Force and cinematographic data were collected during each lift. The augmentation to performance derived from prior stretch was observed to decay as a function of the pause duration. This relationship was accurately described (P less than 0.01) by a negative exponential equation with a half-life of 0.85 s. The nature of this decay is discussed with reference to the implications for stretch-shorten cycle movements that are performed with a period of pause between the eccentric and concentric phases and for stretch-shorten cycle research paradigms.
12名能力各异的经验丰富男性举重运动员以最大重量的95%完成了一系列卧推。这些举重包括一次反弹卧推（在举重的向下和向上部分之间没有延迟）、一次没有向下阶段的卧推，以及两次在举重的向下和向上阶段之间设置了不同暂停时间的卧推动作。在每次举重过程中收集了力量和电影摄影数据。观察到先前拉伸对表现的增强作用会随着暂停持续时间而衰减。这种关系通过一个半衰期为0.85秒的负指数方程得到了准确描述（P小于0.01）。结合在离心和向心阶段之间有一段暂停时间的拉长-缩短周期动作以及拉长-缩短周期研究范式的影响，讨论了这种衰减的性质。
