Objectives. -The present study analyzes the impact of a strength training program on bioenergetics parameters determined at velocity corresponding to maximal oxygen uptake (v(V)over dotO(2) max). Methods. - Sixteen recreational long-distance runners were divided into strength training (STG, n= 9) and control (CG, n=7) groups. Before and after 8 weeks, the volunteers performed: maximal incremental treadmill test, constant-speed running at pre-training v(V)over dotO(2) max, and maximum dynamic strength test (1RM). Energy cost of running (ECr), and aerobic (A(MEA)) and anaerobic (AN(MET)) metabolism contributions were estimated at v(V)over dotO(2) max. Results. - No differences were observed at baseline between groups (P> 0.05). After experimental period, there was an increase in 1RM for STG (27 +/- 18%, P=0.008), but not for CG (P> 0.05). The changes in ECr (pre =0.254 +/- 0.038 vs. post =0.255 +/- 0.037 kJ.m(-1)), A(MET)(pre = 191.5 +26.2 vs. post =193.0 +/- 31.7 kJ), and AN(MET)(pre =20.9 +/- 6.4 vs. post = 21.0 +/- 5.7 kJ) were not significant different (P> 0.05) to STG; as well as to CG (ECr - pre = 0.260 +/- 0.046 vs. post = 0.259 +/- 0.034 kJ.m(-1), A(MET) - pre = 209.7 +/- 30.2 vs. post =203.3 +/- 26.6 kJ, and AN(MET) - pre= 19.3 +/- 6.4 vs. post = 23.9 +/- 4.6 kJ). Conclusions.-These findings suggest that 8 weeks strength training improved the maximum dynamic strength and did not alter bioenergetics parameters measured at v(V)over dot O-2 max in recreational endurance runners.
