Androgen responses to resistance exercise / 中国组织工程研究

ABSTRACT

BACKGROUND:The androgen response to resistance exercise is one of hot topics in sports science research. At present, the androgen responses to resistance exercise show different results. There are different androgen changing trends under different resistance exercise interventions. OBJECTIVE:To have a deep insight into the influence of resistance exercise on the response of human body androgen, clarify research progress in androgen response to resistance exercise, and provide the basic theory for monitoring resistance training. METHODS:Literatures and paper reports about androgen response to resistance exercise are electronical y retrieved from the American Biological Medical Literature Database PubMed from 1986 and 2013. Final y 46 literatures addressing the research progress is analyzed about androgen responses to resistance exercise were included. RESULTS AND CONCLUSION:Studies have shown that, weight lifting (power snatch and power clean), squating, and deadlifting produced higher testosterone levels than the smal muscle groups. Under the same load, eccentric and concentric contractions produced the same hormone response. Adequate training amount and intensity may change the circulating testosterone levels. Short sports intermittent time led to a higher testosterone response than the long intermittent time. The free testosterone levels in youth group were significantly increased compared with the older group before and after exercise. Nutrition intervention affected acute testosterone responses to resistance exercise. Changes in exercise intensity and amount wil alter quiet testosterone levels, once returned to normal training, testosterone levels wil return to baseline values. Resistance exercise can increase androgen receptor content in human skeletal muscles.
