Study aim: To evaluate the effects of two strength training programmes on the explosive force of lower extremities and total testosterone levels in plasma of Brazilian football players.Material and methods: A group of 24 male football players aged 16 - 19 years participated in a 12-week training: non-linear periodised (NLP) or non-periodised (NP), 12 subjects each. Before and after training period, all subjects performed countermovement vertical jump (CMJ), horizontal jump and Flegner's power test, and total testosterone concentrations were determined in plasma.Results: Significant, training-induced changes in CMJ were found in both groups; by 7.4% (p<0.05) in the NLP group and by 8% (p<0.001) in NP group. Also in the long jump (SBJ) significant (p<0.05) changes were noted in both groups, by 0.9 and 4.4%, respectively. Serum testosterone concentrations significantly (p<0.05 - 0.01) increased post-training in both groups and the increase was significantly (p<0.01) greater in the NLP than in NP group.Conclusion: A larger number of athletes in future studies, as well as other sport categories and levels and a longer training period would be advisable in order to strengthen the causal inferences between the variables studied.

Study aim: To assess the effects of aerobic training on body fat content and serum lipid profile.Material and methods: A group of 45 male members of Brazilian Military Police Academy, aged 18 - 32 years, were subjected randomly assigned into 3 subgroups and to 12-week programmes: aerobic fatmax zone training (FG; n = 18), traditional military training (TM; n = 15) and non-training control group (C; n = 12). Body fat content (3 skinfolds), serum lipid profile (total cholesterol, LDL, HDL and triglycerides), waist circumference (WC) and O2max (12-min test) were determined.Results: O2max significantly (p<0.05) increased and body fat content decreased in both experimental group compared with the control one. Significant (p<0.05) reductions in WC and LDL vs. control group were observed in the TM group only.Conclusions: The applied aerobic training induced a decrease in percent body fat irrespectively of the kind of training.
