Performance and acute recovery in endurance runners
Sixteen well-trained endurance runners were evaluated in two different days with the Université de Montréal Track Test (UMTT), and the time limit at maximum aerobic speed test (Tlim). Heart rate and lactate drops were examined during the acute recovery (by walking). Maximum heart rate was higher in UMTT compared with Tlim (p = 0,001). Heart rate recovery in the first minute after both protocols correlated with maximal aerobic speed (r = 0,611 and r = 0,615, p = 0,012, for UMTT and Tlim, respectively); with a correlation detected between HR recovery drops after both protocols (r = 0,824; p = 0,000). The difference between lactate levels at first and 10th min of recovery, was significantly different only in UMTT condition (p = 0,013). In summary: 1) it was found a moderate relationship between maximum aerobic speed and heart rate recovery in distance runners; 2) maximum heart rate is higher in an incremental test compared with a rectangular test in the field; 3) the significant lactate drop at 10 min of recovery only after UMTT, suggest the running protocol dependence of this parameter.
