Statistical analysis was carried out using a one way ANOVA test with post hoc LSD test analysis. The bold represents the abbreviated name of groups, the parameter that was monitored in each experimental week, as well as the statistically significant change of the investigated parameter. T-N- (control); T-N+ (nandrolone); T+N- (swimming training); T+N+ (swimming training plus nandrolone).
