Physiological adaptations in response to aerobic training

[natasha.rh]

Hi,
I know that lung capacity barely increases due to aerobic training, but i was wondering what benefits it would have on an athlete and how would it affect their performance? What adaptations would an athlete expect to see after a 12 week training program?
Thanks!

With lung capacity, there is a slight increase in vital capacity (amount of air that can be expelled after maximal respiration) so body can remove co2 quicker. There is also a decrease in residual volume (Amount of air that must be present in the lungs)

And it takes approx 12 weeks for ALL the adaptations to NOTABLY improve performance.

Through aerobic training, an athlete can also increase VO2 max and maximum oxygen uptake.
A high VO2 max indicates a superior oxygen delivery system and can contribute to outsanding endurnac performance.
Training also makes lungs tissue stronger, an increased efficiency of lungs rather than changes in size.
