Effects of Warming-up on Physiological Responses to Maximal Treadmill Exercise
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.4 Vol.4】
The purpose of this study was to investigate the actual condition of warming-up in athletic events and to clarify the effects of warming-up in supermaximal treadmill exercise on performance and physiological parameters.
1. From the questionnaire, it was found that most of the athletes usually practiced warming-up exercise before the athletic game for 40-90 minutes. The contents of warming-up were jogging, stretching, gymnastics, wind sprint and dash, whereas combinations were varied among athletes. The main purpose of their warming-up was to improve their suppleness and/or circulo-respiratory function.
2. The intensity of warming-up exercise ranged from 30% to 70% of their maximum oxygen uptake: intensity of jogging or wind sprint were higher (about 70% VO₂max) as compared with stretching or gymnastics (about 30% VO₂max). The raise of rectal temperature by warming-up was 0.9 and 1.0℃ for subject M and S, respectively.
3. Although rectal temperature and performance (13-33%) were increased by warming-up, but ventilation, oxygen uptake and blood lactate concentration were not different during and after supermaximal exercise with and without warming-up.
From these results, it is suggested that performance will be improved by warming-up.
