Document Summary

Stride frequency is also known as cadence (slide 10) Cadence doesn"t change much whereas frequency does in terms of fatigue. Gait cycle allows us to see the activation of different muscles (11,12) With shoes we tend to alter or body motion which allows us to have a better stance and technique while running, in contrast to barefoot. Pharynx is a tube used for eating and breathing. Between alveolus and capillary there is a very small distance. Thickness is squared to adjust to the dimensions (26) Primary muscle for the respiratory system is the diaphragm. Top of the diaphragm is all connective tissue. Valsalva maneuver(30)=all people passing out after attempting to deadlift. Contracting numerous muscles at the same time=no blood flow. Inspiration is always up on the spirometer (33,34) Having residual volume is essential for us (alveoli does not stick together) (34) Total lung capacity is dependent on our sitting height. Pa=refers to the respiratory system (pressure in the alveoli)
