Document Summary

Feb 1 chap 4 preventing injuries through fitness training. Functional training: newer technique used to improve strength and neuromuscular control. Involves tri-planar activities designed to challenge the whole body: requires cns to integrate proprioceptive info from multiple muscles to produce a specific movement pattern. Involves concentric, eccentric, and isometric muscle contractions: allows not only for development of strength and control but also high levels of core strength and flexibility. 4 components of cardiorespiratory system: heart as you get fitter, we see sv increasing due to the heart muscles getting stronger. With exercise, our heart chambers stretch and we are able to pump more blood out. At rest, our body doesn"t need as much blood and our co is 5l/min. Our sv increases and our hr decreases so our heart works less at rest: lungs ventilation isn"t a limiting factor to perform exercise. Improvements in endurance are the results of improvement in these 4 components.
