Cardiorespiratory and blood flow data at rest and during exercise

Rest 5 min 10 min 15 min 30 min 60 min 90 min
Pulmonary VO2 0.33 ± 0.02 0.91 ± 0.03* 0.99 ± 0.02* 0.94 ± 0.04* 0.95 ± 0.02* 0.94 ± 0.02* 0.98 ± 0.03*
Thigh blood flow 0.24 ± 0.03 4.34 ± 0.20* 4.48 ± 0.21* 4.38 ± 0.22* 4.40 ± 0.22* 4.39 ± 0.18* 4.50 ± 0.23*
A—V O2 difference 7.4 ± 0.7 12.9 ± 0.4* 13.5 ± 0.5* 13.2 ± 0.8* 13.1 ± 0.6* 12.8 ± 0.8* 12.6 ± 0.7*
[Haemoglobin] 15.1 ± 0.5 15.8 ± 0.5 15.7 ± 0.5 15.6 ± 0.5 15.6 ± 0.6 15.3 ± 0.5 15.3 ± 0.5

Values are means ±s.e.m.(n = 6). Pulmonary VO2 and leg blood flow are expressed in 1 min−1. Arterial-venous difference (A—V) in O2 content is expressed in ml(100 ml blood)−1. Haemoglobin concentration is expressed in g(100 ml arterial blood)−1.
