physiological adaptations in response to training Flashcards
1
Q
Physiological Adaptations
A
- HOMERS
- Haemoglobin levels
- Oxygen intake
- Muscle hypertrophy
- Effect on muscle fibres
- Resting Heart Rate
- Stroke Volume
2
Q
Resting Heart Rate
A
- Number of beats per minute
- Athlete resting heart rate < Non-athlete resting heart rate
- Aerobic training decreases resting heart rate
3
Q
Stroke Volume
A
- Volume of blood leaving heart with each heartbeat
- The greater the stroke volume, the longer and faster an athlete can exercise
- Training increases ventricle size
4
Q
Haemoglobin Level
A
- Haemoglobin levels increase as a result of training
- Blood plasma and red blood cells increase as a result of training
5
Q
Oxygen Intake / VO2 Max
A
- Amount of oxygen that is absorbed into blood stream
- VO2 max measures maximum oxygen intake in litres per minute
- Tested using submaximal test
E.g.12 minute run
6
Q
Lung Capacity
A
- Amount of air moving in and out of lungs in 1 breath
- More air moving in / out means more O2 absorbed into blood stream
- Total lung capacity is about 6L
- Vital Capacity
7
Q
Muscle Hypertrophy
A
- Increase in diameter of the muscle
8
Q
Effect on Muscle Fibres
A
- Red slow twitch: Many capillaries, slow ATP production
- White fast twitch: Few capillaries, fast ATP production
