How does VO2max change with chronic aerobic endurance training? What causes this change? Answer Increases, due to increased Q (cardiac output; due to increased SV, not HR) How is HR affected by chronic aerobic endurance training? Answer Unchanged or decreased slightly Heart adaptations to chronic aerobic endurance training? Answer Left ventricle hypertrophy and chamber diameter increases Coronary arteriole densities and diameters increase Blood adaptations to chronic aerobic endurance training? Answer 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? Answer 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? Answer Possible slight hypertrophy of type I fibers Increased: capillary density, mitochondria density, glycogen stores, triglyceride stores, and oxidative enzymes
