VO2max RT, T, GH, and IGF-I levels were 31.2 ± 6.2 ml/min/kg, 106.7 ± 23.2 s, 8.3 ± 1. 3 ng/mL 1.6 ± 0.7 ng/mL, 106.5 ± 27.0 ng/mL in master athlete group and 18.8 ± 5.1 ml/min/kg, 148.3 ± 39.3 s, 5.4 ± 1.7 ng/mL, 0.8 ± 0.3 ng/mL, 90.2 ± 23.8 ng/mL in sedentary control group, respectively. The differences between regularly exercising males and the control group of sedentary males were found to be statistically significant. The results showed that long-term exercise decreased RT and increased VO 2max, T, and GH in elderly males; elevated serum T and GH levels may be advantageous for brain functions.Serum testosterone, growth hormone, and insulin-like growth factor-1 levels, mental reaction time, and maximal aerobic exercise in sedentary and long-term physically trained elderly malesArticle10.1080/00207450490430499
