Performing warm-ups increases muscle temperature and blood flow, which contributes to improved exercise performance and reduced risk of injuries to muscles and tendons. Stretching increases the range of motion of the joints and is effective for the maintenance and enhance-ment of exercise performance and flexibility, as well as for injury pre-vention. However, stretching as a warm-up activity may temporarily de-crease muscle strength, muscle power, and exercise performance. This study aimed to clarify the effect of stretching during warm-ups on mus-cle strength, muscle power, and muscle endurance in a nonathletic population. The subjects of this study consisted of 13 physically active male collegiate students with no medical conditions. A self-assessment questionnaire regarding how well the subjects felt about their physical abilities was administered to measure psychological readiness before and after the warm-up. Subjects performed a non–warm-up, warm-up, or warm-up regimen with stretching prior to the assessment of the isokinetic moments of knee joints. After the measurements, the respec-tive variables were analyzed using nonparametric tests. First, no statis-tically significant intergroup differences were found in the flexor and extensor peak torques of the knee joints at 60˚/sec, which were as-sessed to measure muscle strength. Second, no statistically significant intergroup differences were found in the flexor and extensor peak torques of the knee joints at 180˚/sec, which were assessed to measure muscle power. Third, the total work of the knee joints at 240°/sec, in-tended to measure muscle endurance, was highest in the aerobic-stretch-warm-ups (ASW) group, but no statistically significant differ-ences were found among the groups. Finally, the psychological readi-ness for physical activity according to the type of warm-up was signifi-cantly higher in ASW. Simple stretching during warm-ups appears to have no effect on variables of exercise physiology in nonathletes who participate in routine recreational sport activities. However, they seem to have a meaningful effect on exercise performance by affording psy-chological stability, preparation, and confidence in exercise perfor-mance.
