Individual variation in aerobic capacity has been extensively studied, especially with respect to condition, maturity or pathogen infection, and to gain insights into mechanistic foundations of performance. However, its relationship to mate competition is less well understood, particularly for animals in natural habitats. We examined aerobic capacity [maximum rate of O2 consumption (VO2,max) in...

We have studied 73, top level Indian sportsmen for VO2 max and heart rates during work and recovery. High negative values of 'r' between VO2 max and heart rate during work and recovery have been observed. Absolute VO2 max, VO2 max/kg body wt/min and VO2 max/kg lean body mass/min are found to play an important role in influencing recovery of heart rate, more so in the initial phases. A similar t...

Convenient methods were developed for measuring maximum oxygen consumption (VO2 max) in untrained small mammals during treadmill exercise and cold exposure. Deer mice (Peromyscus maniculatus) were run once, for 6-min periods at velocities exceeding maximal aerobic running speed, while instantaneous oxygen consumption was measured. The VO2 max during cold exposure was determined using high wind ...

OBJECTIVES This study explores whether cardiovascular fitness levels and senescent decline are similar in the Tsimane of Bolivia and Canadians, as well as other subsistence and industrialized populations. Among Tsimane, we examine whether morbidity predicts lower levels and faster decline of cardiovascular fitness, or whether their lifestyle (e.g., high physical activity) promotes high levels a...

INTRODUCTION The aim of this study was to estimate maximal aerobic capacity (VO2 max), to determine its associated factors among workers of industrial sector of Iran and to develop a regression equation for subjects' VO2 max. METHODS In this study, 500 healthy male workers employed in Shiraz industries participated voluntarily. The subjects' VO2 max was assessed with the ergocycle test accord...

We studied relations between maximal O2 consumption (VO2 max) during forced exercise and subordinate traits associated with blood O2 transport and cellular respiration in four lines of mice selectively bred for high voluntary wheel running (S lines) and their four nonselected control (C) lines. Previously, we reported VO2 max of 59 females at three Po2 (hypoxia = 14% O2, normoxia = 21%, hyperox...
