Diferentes intensidades de aquecimento sobre o desempenho e respostas fisiológicas em corrida até a exaustão em esteira

Abstract

The purpose of this study was to analyze the effect of different warm-up protocols on performance and physiological responses when running on the treadmill until exhaustion. Eleven volunteers (10 men and 1 woman 23.8 ± 5.3 years old, 69.0 ± 10.8 kg and 1.79 ± 0.10 m) physically active and acquainted with racing, initially performed an maximum aerobic velocity test (VAM) and, then three experimental situations: control - CON (without warm-up), low intensity warm-up (ABI) and high intensity warm-up (AAI). The ABI consisted of a 10- minute run at 60% of the VAM, and the AAI in a 10-minute run at 60% of the VAM followed by 5 sprints of 15 seconds at 100% of the VAM with a 45-second interval. A test until exhaustion (tlim) at 100% of the VAM was performed after each intervention. The t lim was 378.9 ± 72.7 s, 385.0 ± 91.6 s and 411.2 ± 116.8 in the CON, ABI and AAI situations, respectively (p> 0.05). Five volunteers (45.5%) performed better after AAI, four volunteers (36.4%) after ABI and only two volunteers (18.2%) presented better performance in the control situation. The results of the present study showed that the warm-up protocols used were not enough to cause improvement in t lim performance.
