Document Summary

* limitations mostly viewed as occurring through deliver rather than utilisation (occurs at level of central and peripheral circulation) *respiratory system not generally seen as rate limiting, as po2 decreases very little, however respiratory system becomes limiting at high altitude. List and explain the factors in uencing vo. Body size: larger muscles increase vo2 max greater o2 extraction. Age: vo2 max generally decline with age. Gender: vo2 max lower in females smaller heart size so smaller sv, also have lower haematocrit levels, these factors act to decrease oxygen delivery. Muscle bre composition: higher proportions of slow twitch bres (type 1) are more oxidative and hence in uence vo2 max. State of training: endurance athletes tend to have higher vo2 max. Topic 4: exercise in extreme environments: describe how body core temperature is maintained. Convection heat transferred via air/water in contact with body where uid is moving (form of conduction), heat loss dependent on temp and velocity.
