Document Summary

When a person engages in a sustained bout of pa, nearly all systems and organs come into play to support the activity. Primary functions: define the body, move the body, bones joints. Types are muscle: cardiac muscle: specialized that can move without stimulus, skeletal: we control and give us movement, smooth muscle: involuntary like muscles that line digestion and move without us thinking about it. Slow-twitch muscle fiber: slow in contraction, steady power/endurance aerobic, endurance. Fast twitch muscle fiber: fatigues early, fasting in contraction, speed/ fatigues easily anaerobic.

Atp is generated by 3 basic energy systems: atp pcr system: 10-20 sec anaerobic. It produces atp quickly but short: glycolytic system: <2 min anaerobic.
