Effects of circuit weight training by intensity on stress hormones and antioxidant capacity in high-school wrestlers.
We aimed to investigate the effects of 8-week circuit weight training by intensity on blood stress hormones and antioxidant capacity in high-school wrestlers. This study involved 27 male wrestlers with >2 years of wrestling experience who were randomly assigned to either a low intensity (n=13) or a high-intensity circuit weight training group (n=14). The participants performed circuit weight training for 60 min per session, 3 times per week for 8 weeks. The low- and high-intensity circuit weight training exercises were performed at 50%-60% and 70%-80% of one-repetition maximum for 10 stations, respectively, and 8-15 repeated sessions per station were performed in order. No changes were observed in adrenocorticotropic hormone (ACTH), cortisol, epinephrine, and norepinephrine levels between the two training groups. When compared to levels before the training, ACTH and epinephrine levels decreased, whereas cortisol levels increased. However, no difference was observed in norepinephrine levels. Further, no differences were observed in malondialdehyde (MDA) and glutathione peroxidase (GPX) levels between the two groups. However, MDA and GPX levels were increased from those before training. Changes in superoxide dismutase levels were observed between the two groups, but the change was significant only in the high-intensity circuit weight training group. Long-term training did not increase lipid peroxidation, but increased the activity of antioxidant enzymes that defend against oxidative stress. The antioxidant defense system in tissues can be regulated by exercise intensity as well as physical training status.
期刊介绍:
The Journal of Exercise Rehabilitation is the official journal of the Korean Society of Exercise Rehabilitation, and is published six times a year. Supplementary issues may be published. Its official abbreviation is "J Exerc Rehabil". It was launched in 2005. The title of the first volume was Journal of the Korean Society of Exercise Rehabilitation (pISSN 1976-6319). The journal title was changed to Journal of Exercise Rehabilitation from Volume 9 Number 2, 2013. The effects of exercise rehabilitation are very broad and in some cases exercise rehabilitation has different treatment areas than traditional rehabilitation. Exercise rehabilitation can be presented as a solution to new diseases in modern society and it can replace traditional medicine in economically disadvantaged areas. Exercise rehabilitation is very effective in overcoming metabolic diseases and also has no side effects. Furthermore, exercise rehabilitation shows new possibility for neuropsychiatric diseases, such as depression, autism, attention deficit hyperactivity disorder, schizophrenia, etc. The purpose of the Journal of Exercise Rehabilitation is to identify the effects of exercise rehabilitation on a variety of diseases and to identify mechanisms for exercise rehabilitation treatment. The Journal of Exercise Rehabilitation aims to serve as an intermediary for objective and scientific validation on the effects of exercise rehabilitation worldwide. The types of manuscripts include research articles, review articles, and articles invited by the Editorial Board. The Journal of Exercise Rehabilitation contains 6 sections: Basic research on exercise rehabilitation, Clinical research on exercise rehabilitation, Exercise rehabilitation pedagogy, Exercise rehabilitation education, Exercise rehabilitation psychology, and Exercise rehabilitation welfare.
