Hormonal responses to high- and moderate-intensity strength exercise.

摘要: The hormonal responses of nine male, strength athletes to exercise were examined. performed one moderate- and high-intensity workout. In the workout, load was 100% each subject's three-repetition maximum (3-RM) for squats front squats, six-repetition (6-RM) leg extensions. moderate-intensity 70% protocol. Rest periods between sets 4-6 min both workouts. Blood samples taken before, 30 into, every 15 1st h after exercise, then 3, 7, 11, 22 33 thus allowing examination acute prolonged responses. analyzed testosterone, luteinizing hormone (LH), follicle stimulating (FSH), cortisol, adrenocorticotrophic (ACTH), growth (GH), insulin-like factor (IGF-1), insulin, sex binding globulin, creatine kinase, total protein, glucose lactate. testosterone cortisol greater during protocol as compared response associated with an increase in ACTH concentration. LH FSH showed no either Acute GH not different protocols. There great inter-individual differences significant protocols regard any hormone. trials, IGF-1 concentrations significantly lower at 0800 hours morning found before exercise. mechanisms responsible reducing concentration these trials are unclear, it is known if this reduction observed physiological significance.
