Eleven international jumpers and throwers engaged in year round training were divided into experimental (n = 6) and control (n = 5) groups. The experimental group was tested before and after a 3 weeks simulated hypergravity period, and again 4 weeks after the hypergravity period. The high gravity condition was created by wearing a vest weighing about 13% of the subjects body weight. The vest was worn from morning to evening including the training sessions, and only removed during sleep. The daily training of all subjects consisted of classical weight training and jumping drills. No changes in the ordinary training program were allowed in the experimental group, except for the use of the vest. Vertical jumps, drop jumps and a 15 s continuous jumping test were used to measure the explosive power characteristics of the subjects. After the hypergravity period the experimental subjects demonstrated significant (5-10%, P less than 0.05-0.01) improvements in most of the variables studied: however, 4 weeks after cessation of the high gravity period they tended to return towards the starting values. No changes were observed in the results of the control group. The improvement observed in the experimental subjects was explained as fast adaptation to the simulated high gravity field. It is suggested that adaptation had occurred both in neuromuscular functions and in metabolic processes.
11名常年进行训练的国际跳远和投掷运动员被分为实验组（n = 6）和对照组（n = 5）。实验组在为期3周的模拟超重力期前后接受测试，并在超重力期结束后4周再次接受测试。通过穿着一件重量约为受试者体重13%的背心来营造高重力环境。背心从早到晚都要穿着，包括训练时段，只有在睡觉期间才脱下。所有受试者的日常训练包括传统的重量训练和跳跃练习。实验组除了使用背心外，普通训练计划不得有任何改变。使用垂直跳、下落跳和15秒连续跳跃测试来测量受试者的爆发力特征。超重力期结束后，实验组受试者在大多数研究变量上都有显著（5 - 10%，P小于0.05 - 0.01）改善；然而，在高重力期结束4周后，他们的各项指标又趋于回到初始值。对照组的结果未观察到变化。实验组受试者所观察到的改善被解释为对模拟高重力场的快速适应。研究表明，神经肌肉功能和代谢过程都发生了适应性变化。
