摘要

This study compared the effects of 4 weeks of training prescribed by peak velocity (V peak ) or velocity associated with maximum oxygen uptake (vVO 2max ) in moderately trained endurance runners. Study participants were 14 runners (18–35 years) randomized into 2 groups, named group VO 2 (GVO 2 ) and group V peak (GVP). The GVO 2 had training prescribed by vVO 2max and its time limit (t lim), whereas the GVP had training prescribed by Vpeakand its tlim. Four tests were performed on a treadmill: 2 maximum incremental for Vpeakand vVO2maxand 2 for their tlim. Performance (10 km) was evaluated on a 400 m track. Evaluations were repeated after 4 weeks of endurance training. The results showed a significant effect of training on Vpeak[GVP (16.7±1.2–17.6±1.5 km.h−1), GVO2(17.1±1.9–17.7±1.6 km·h−1)]; vVO2max[GVP (16.4±1.4–17.0±1.3 km·h−1), GVO2(17.2±1.7–17.5±1.9 km·h−1)]; and 10 km performance [GVP (41.3±2.4–39.9±2.7 min), GVO2(40.1±3.4–39.2±2.9 min)]. The Vpeakhighly correlated with performance in both pre- and post-training in GVP (–0.97;–0.86) and GVO2(–0.95;–0.94), as well as with vVO2maxin GVP (–0.82;–0.88) and GVO2(–0.99; –0.98). It is concluded that training prescribed by Vpeakpromoted similar improvements compared to training prescribed by vVO2max. The use of Vpeakis recommended due to its practical application and the low cost of determination.
