Relevance. Сardiovascular status could be assessed by maximal aerobic capacity (VO2max) through direct analysis of the gases involved in pulmonary ventilation and monitoring fluctuations intervals between beats over time as heart rate variability. The aim study was to investigate relationship VO2max variability young adults. Materials Methods. A total 100 adults ages 18 25 were included observa...

Locomotor performance and activity energetics were analyzed in 19 individual helodermatid lizards ranging in mass from 24.5-1220 g. We measured maximum sprint speeds, endurance on a treadmill, cost of transport, and aerobic capacity (rO2max) at a mean body temperature of 30.8 C. The maximum sprint speed for both Heloderma species averaged 1.7 km/h, which is among the lowest recorded for lizards...
