[Effects of different intensity endurance training on hypothalamus-pituitary regulatory function]

Effects of different intensity endurance training on several main hormones related to exercise in the rat hypothalamus-pituitary-adrenal axis-gonadal axis were studied. The results indicated that different intensity endurance training played different roles in their synthesis and release. In 36 m/min training group, the reserve of beta-endorphine beta-EP, in hypothalamus-pituitary, the capacity of body stress and aerobic capacity were increased, whereas the stress level in exercise, the luteinizing hormone LH content were decreased as compared with other groups. It is suggested that proper endurance training may elevate the sports capacity in which beta-EP may play an important role in regulating adrenal axis and gonadal axis directly and indirectly.
