Control group (C0, n = 3) did not exercise; C42 = control after 42 days (did not exercise); E0 = only conditioning (before); E42 = only conditioning after 42 days; Car0 = before conditioning and L-carnitine supplementation; Car42 = conditioning and supplementation with L-carnitine after 42 days; Chr0 = before conditioning and chromium supplementation; Chr42 = conditioning and supplementation with chromium for 42 days. Effect of conditioning: E0 vs. E42; Car0 vs. Car42 and Chr0 vs. Chr42. Comparisons between control group and exercise conditioning/exercise conditioning-supplemented groups: C42 vs. E42; C42 vs. Car42 and C42 vs. Chr42. Comparisons between exercise conditioning and exercise conditioning-supplemented groups: E42 vs. Car42; E42 vs. Chr42. The numbers are P values and evaluation time with significance <0.05 are in bold.
