10名受试者的右下肢连续3天被动负重8min，以确定这种负荷对直腿抬高角的影响。每天在加载15秒后、此后在加载8分钟期间每30秒、以及加载后10分钟和24小时通过电影确定角度。在三天的负荷后24小时，实验组的直腿抬高角度比最初平均大4.4度。这种增加在统计学上不显著。10名对照受试者的可比角度平均增加0.6度。4.4度的增加表明，肌肉在连续三天施加8分钟的拉伸后缓慢伸长。
The right lower extremities of 10 experimental subjects were passively loaded for 8 minutes on three consecutive days to determine the effects of such loading on the angle of straight-leg raising. The angle was determined cinematographically each day after loading for 15 seconds, every 30 seconds thereafter during 8 minutes of loading, and 10 minutes and 24 hours after loading. Twenty-four hours after three days of loading, the straight-leg-raising angle of the Experimental Group was an average of 4.4 degrees greater than it was initially. This increase was not statistically significant. The comparable angle of 10 control subjects increased an average of 0.6 degrees. The 4.4 degree increase suggests that muscle lengthens slowly in response to 8 minutes of stretching applied on three consecutive days.
