Document Summary
Knes 373 lecture 25 oxygen transport, delivery, and utilization. What is vo2: vo2 = q x a-vo2diff, when energy demand (atp demand) increases, we have an immediate increase in hr, sv, and a-vo2 difference to provide the oxygen that is needed in the working muscle. 1 per w: cp = critical power = greatest rate at which stability can be achieved, below anaerobic threshold or respiratory compensation threshold, moderate: no increase in[la] and stable vo2 (~10 ml min- Lactate threshold (lt) or gas exchange threshold (get) = separates moderate from heavy intensity exercise: maximal lactate steady-state (mlss) or critical power (cp) = separates heavy from very-heavy/severe intensity exercise. 50": 10 km world record: 26:17:53 pace: 2"38"" per km, 21 km world record: 58:23 pace: 2"47"" per km, 42 km world record: 2:01:39 pace: 2"54"" per km (or 400 m in 70 s) If exercise intensity is low enough, everyone will reach steady state at some point.
