Steady state and kinetic response of VO2 and leg blood flow following a 21 day expedition to 6200 M

VO2 and leg blood flow (LBF) kinetics were assessed in 5 males (age: 28 ± 2 y: and ht: 173.7 ± 3.0 cm, mean ± SE) one week before and 3 days after a 21-day climb to the summit of Mt. Denali, Alaska (6200 m). Body mass and cycling VO2 max were not different pre and post-climb (BM = 76.9 ± 3.7 vs 75.5 ± 2.9 kg; VO2 max = 52.3 ± 2.1 vs 50.6 ± 1.9 ml/kg/min). VO2 and LBF kinetics were assessed by the mean response time (MRT, time to 63% of the …
