Document Summary

Highest mitochondrial transformation of chemical energy per minute. Measured as v02 max (maximal oxygen uptake) Total chemical energy available to perform aerobic work. Endurance performance, time to exhaustion, biochemical indicators (invasive) Begin as predominantly anaerobic and transition to aerobic. Estimation of pure aerobic metabolism is impossible to perform: constant influence of anaerobic metabolism. Contribution of non oxidative metabolism is minimal. Same equipment with cycle modifications (seat closer to pedals, decrease pedal circumference, visual cadence) Treadmill vs. cycle: max v02 cycle ~ 10% < treadmill (muscle mass, arm ergometry max v02 ~ 60-70% of cycle, treadmill requires ++ habituation (fear) Options: focus on mechanical power during maximal effort. Watts/wattskg (watts increase with fitness: extrapolate submaximal performance. Pwc170 (physical work capacity at 170 bpm) population estimates: anaerobic threshold (blood lactate) Estimate is not accurate: inconsistent results with last 2. V02 plateau (ml/kg/min) despite increased workload: only 4-50% of children reach plateau, unable to maintain pace(at max) with encouragement.
