- Abstract
Purpose: The purpose of this research is to study the effects of aging and combined training (sprint and strength) on catecholamine responses [adrenaline (A) and noradrenaline (NA)]. Methods: Thirty-two male subjects voluntarily participated in this study. They were randomly divided into four groups: A young trained group (age 21.4 ± 1.2 years, YT, n = 8), a young control group (age 21.9 ± 1.9 years, YC, n = 8), a middle-aged trained group (age 40.8 ± 2.8 years, AT, n = 8) and a middle-aged control group (age 40.4 ± 2.0 years, AC, n = 8). YT and AT participated in a high intensity sprint and strength training program (HISST) for 13 weeks. All the participants realized the Wingate-test before (P1) and after (P2) HISST. Plasma A and NA concentrations were determined at rest ( A, NA) and at the end of exercise ( A, NA). Results: At P1, a significant difference ( p < 0.05) in terms of age was observed for NA and A between YT and AT and between control groups YC and AC. This age effect disappeared after training when compared YT and AT. After HISST, A increased significantly ( p < 0.05) in YT and AT (from 3.08 ± 0.17 to 3.23 ± 0.34 nmol l in YT and from 3.23 ± 0.52 to 4.59 ± 0.10 nmol l in AT). However, NA increased significantly ( p < 0.05) in AT only (from 3.34 ± 0.31 to 3.75 ± 0.60 nmol l). A was highly increased in AT compared to YT (4.59 ± 0.10 vs. 3.23 ± 0.34 nmol l), respectively. Conclusion: The combined training (sprint and strength) appeared to reduce the age effect of the catecholamine response both at rest and in response to exercise.
