摘要：It has been well established that the muscular work capacity or muscular endurance may be increased with training (Hedvall, 1915, McGlynn 1968) Maison et al 1941). In the systematic study on muscular endurance, Ikai et al (1965) found that the best training effects could be obtained between the ages of 12 and 15. As to the physiological mechanism to improve muscle work capacity, many authors have paid their attention to the blood flow through active muscles (Hewlett et al 1909, Grant 1938, Barcroft et al 1949, Corcondilas et al 1964, Lundholm et al 1965, Kontos et al 1965, Wahren 1966).In an attempt to determine what factors would be involved in the improvement of muscular endurance, present authors found the peak blood flow after exercise was increased in proportion to the muscular endurance development during training. Vanderhoof et al (1961) have demonstrated that the blood flow debt was decreased markedly associated with endurance improvement, suggesting the increase in blood flow during exercise. In the study of postexercise hyperemia in trained and untrained subjects, Elsner and Carlson (1962) found that the athletes and nonetheless had greater blood flow in the muscle during exercise than the untrained nonetheless. Rohter, Rochelle and Hyman (1963)) made an investigation on exercise blood flow of the swimmers during training and detraining periods and have found a significant increase in blood flow during training period. It was supposed from these studies that the increase of blood supply to the muscle was a major factor for endurance development. Individual differences in the increase in blood supply through systematic training would indicate the trainability of muscular endurance. Although the changes of blood flow during training have been studied by several authors, training effect on blood flow for endurance in relation to age and sex has not been studied. This study had been conducted to contribute to further analysis of muscular endurance training with respect to blood flow in males and females of different ages.
