Question | Answer |

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 |
