CHAPTER 3 - Cardio, Respiratory and Metabolic Adaptation
Regular aerobic exercise leads to significant cardiovascular, metabolic, and respiratory adaptations. Cardiovascular changes include increased stroke volume, heart size, and capillarization of the heart muscle, resulting in lower heart rates during various workloads and at rest.
開啟
Anaerobic exercise - increase aerobic capacity - increase buffering capacity - Glycolytic system - ATP-PCr system - small increases in stroke volume - decreased resting blood pressure is greater - decreased submaximal heart rate - decreased resting heart rate - small increase in left ventricle size - small increase in VO2 Max - small increase in cardiorespiratory endurance Aerobic exercise 3. Metabolic adaptations - glycogen sparing effect: less rely on carbo/glycogen - muscle store more triglyceride - muscle store more glycogen - increase aerobic enzyme activity - decreased VO2 during submaximal exercise - increased capillary density - increased mitochondrial density 2. CV adaptations - decreased heart recovery - lower heart rate during max workloads - lower heart rate during sub max workloads - lower resting heart rate - increased stroke volume - increased capillarisation of the heart muscle - heart size - cardiac hypertrophy 1. Respiratory adaptations - Increased respiratory rate and pulmonary ventilation at maximal
exercise levels - increased Tidal Volume at maximal exercise levels - slight increase in Total lung Capacity - respiratory system functioning usually does not limit performance - arterial-venous O2 difference - pulmanory diffusion - pulmanory ventilation CHAPTER 3 - Cardio, Respiratory and Metabolic Adaptation
