Abstract

Stretching has been shown to reduce maximal power in human subjects after an acute stretching protocol. Twenty-two college-aged males performed acute static stretches for the lower extremities for approximately 14 minutes (experimental group) or sat quietly for 15 minutes (control group). Subjects received both treatments in a random order on separate evenings. Following the treatment protocol (stretch or no-stretch) the subjects performed a series of vertical jumps at 5-minute time intervals. Two trials were allowed at each data collection period. The results indicate that acute stretching has no significant effect on vertical jump, F(6,126) = 0.01, p >0.92, nor is there a significant difference between any of the individual data collection periods for stretch versus no-stretch, F(6,126) = 1.89, p >0.08. Significant changes did occur between specific time periods with a marked rise taking place in the first 10 minutes after the treatment protocol was completed, F(6,126) = 23.74, p <0.001. This data suggests that stretching itself does not affect vertical jump at any time within 30 minutes after the stretch. Changes do occur in vertical jump over time that can possibly be accounted for by a warm-up effect achieved through repeated vertical jumps.
