How does VO2max change with chronic aerobic endurance training? What causes this change? - ANS - Increases, due to increased Q (cardiac output; due to increased SV, not HR) How is HR affected by chronic aerobic endurance training? - ANS - Unchanged or decreased slightly Heart adaptations to chronic aerobic endurance training? - ANS - Left ventricle hypertrophy and chamber diameter increases Coronary arteriole densities and diameters increase Blood adaptations to chronic aerobic endurance training? - ANS - Increased blood volume Increased plasma (within 24 h) Increased red blood cell volume (within a few weeks) 5 Respiratory system adaptations to chronic aerobic endurance training? - ANS - Increased ventilatory muscle endurance, aerobic enzymes, and tidal volume Decreased O2 cost of breathing and breathing frequency Skeletal muscle adaptations to chronic aerobic endurance training? - ANS - Possible slight hypertrophy of type I fibers Increased: capillary density, mitochondria density, glycogen stores, triglyceride stores, and oxidative enzymes Skeletal system adaptations to chronic aerobic endurance training? - ANS - Possible increase of BMD
