title: Anaerobic threshold determination in master endurance runners.
abstract: Twenty middle aged endurance runners underwent physiological testing to determine their maximal oxygen uptake (VO2max), lactate threshold, ventilatory threshold, the slope variation point (SVP) of the linear relationship between running speed (RS) and heart rate (HR) both on the treadmill and during a field test, and the onset of blood lactate accumulation point. The RS, HR, VO2 and blood lactate concentration at which the different thresholds occurred were highly correlated (0.70 < r < 0.95; p < 0.01). The various indices of aerobic-anaerobic transition in the master athletes examined were shown to occur at a comparable percentage of their VO2max as compared to their younger counterparts. The tests developed for, and commonly used in adult athletes, are equally valid in this age group.
