Lec 12

Maximal capacity organism to supply and utilize oxygen – maximal rate of aerobic phosphorylation
1 LO2 5 kcal of aerobic energy
Maximal Rate of Aerobic energy transformation Multiply x5 kcal with O2 consumption
To determine O2 consumption -Test manually -Test exercise performed (specifically) to get ^ O2 consumed
Volition of fatigue when humans cannot exercise anymore
Single stage single, supra-maximal workload -Based on the size of the person & workload -One load as far as you can go
Multiple stage progressively incremental exercise testing – Graded Exercise Testing (GXT) -Exercise is built into the stage
Body Surface Area your whole body / skin
how does body mass effectVO2 max Body mass related to muscle weight -Skeletal mass & muscle mass = relationship -^ body mass = ^ muscle mass = ^ O2 consumption
There is a direct relationship between Body Surface Area, body mass, muscle mass, and Absolute Vo2 max Vo2 max is usually expressed relative to body mass – milliliters of oxygen consumed per kg of body mass per minute: ml·kg-1·min-1 - Relative Vo2 max
Relative Vo2 max is a better predictor of aerobic fitness, health-related fitness, and endurance performance in weight–bearing sports and activities -3.5 L-min -1 -^ relative VO2 max = healthier
Absolute Vo2 max is a better predictor of performance in non-weight-bearing endurance sports and activities
Relative Vo2 max equation Vo2 max • intensity / 100%
Effect of Age & Gender on VO2 max Puberty = ^ hormones = max O2 consumption difference - Female does not increase as fast as boys
