Document Summary

Acute responses of the body to a single bout of exercise. Cardiovascular system: increase in heart rate, stroke volume, cardiac output, bp, blood flow to tissues. Pulmonary system: increase in air movement & blood flow to lungs. Muscular system: increase in force, energy & heat production. Endocrine system: increase in release of epinephrine + norepinephrine (*recall endocrine system hormones) Chronic adaptations of body systems to physical activity & exercise at same absolute workload, body starts adapting. Cardiovascular system: decrease in heart rate, increase in stroke volume + cardiac output stroke volume (sv) is the volume of blood pumped from one ventricle of the heart with each beat. ;high sv= blood is pumped btwn ventricles faster = in healthy ppl ;low sv= blood is pumped slower= unhealthy. Pulmonary system: improved air movement, increased blood flow to lungs. Muscular system: decreased lactic acid formation, increased energy production from fat long, less intense. Workouts= burn more fat to burn fat, run marathonsshort, intense.
