Chapter 11 - Adaptations to Training Flashcards
Definition of cardiorespiratory endurance
The ability to maintain prolonged, dynamic exercise
7 changes caused by aerobic training
- Heart size
- Stroke volume
- Heart rate
- Cardiac output
- Blood flow
- Blood pressure
- Blood volume
Rate of decrease in resting heart rate after training
1 bpm per week
Change in nervous system activity in the heart after training
Increase in parasympathetic activity, decrease in sympathetic activity
True/false: Maximal heart rate shows no significant change with training
True
Training affects _______ cardiac output but not _________ cardiac output
- Maximal
- Resting
Change in total blood volume after exercise
Increase
Blood pressure _______ at a given submaximal intensity as a result of training
Decreases
Effect of training on pulmonary ventilation
Decreases at a given submaximal intensity, increases at maximal intensity due increased tidal volume
True/false: Pulmonary diffusion increases only at maximal intensity as a result of exercise
True
5 muscle factors
- Fibre type
- Capillary supply
- Mitochondrial function
- Myoglobin content
- Oxidative enzymes
2 causes of increased VO2 max
- Increase in cardiac output
- Increase in capillary density
True/false: Performance usually will not increase after VO2max plateaus
False (performance will continue to increase as a result of the lactate threshold continuing to increase)
ATP-PCr system shows ________ in enzymatic activity with training
Little/no change
Glycolytic system shows ________ in enzymatic activity with training
Increases
