RESPIRATION


 * 1) Resting Ventilation rates from 12-16 cycles/minute to 10 12 cycles/minute
 * 2) Increases the tidal volume (The amount of air taken in with which each breath) from 500 milli litre/minute to about 550/600 milli litre/minute.
 * 3) The capacity to utilize oxygen is a result of the functional capacity of the heart, lungs, circulatory system, blood and enzyme.
 * 4) Greater depth of respiration during maximal exercise due to the grater strength of the respiration muscles of the rib cage.
 * 5) Oxygen deptdebt [sic] capacity may be increased.
