General Adaptation Syndrome Flashcards
(14 cards)
What is the General Adaptation Syndrome?
It helps explain how biological systems such as our body respond to stressors.
What two principles does GAS account for?
- Homeostasis.
- Allostasis.
What are the three phases of short-term responses?
- Alarm.
- Resistance.
- Exhaustion.
Describe the ‘alarm’ phase of a short-term response.
- The stressor is present.
- The body is managing to cope but the immune system begins to weaken.
Describe the ‘resistance’ phase of a short-term response.
- The body is working in overdrive causing a depressed immune system.
- This increases the chance of illness or injury.
Describe the ‘exhaustion’ phase of a short-term response.
- The body breaks down and can no longer take the neglect.
- This results in illness or injury.
Outline the phases that result in neither a positive nor negative long-term adaptation and describe why this occurs.
- stress > fatigue > recovery > supercompensation > return to baseline
- If the interval between loading bouts is too long or the load is not adequately progressed net adaptation will not occur.
Outline the phases that result in a negative long-term adaptation and describe why this occurs.
- stress > fatigue > incomplete recovery > no super-compensation > further stress > chronic decline > injury
- This occurs as there is an incomplete recovery followed by the re-application of further stress, resulting in a chronic decline.
Outline the phases that result in a positive long-term adaptation and describe why this occurs.
- stress > fatigue > recovery > super-compensation > return to baseline > progressive stress > chronic improvements
- Because progressive stress is applied after an appropriate recovery period this results in chronic improvement overtime.
What is the definition of acute responses?
- Immediate changes in cells, tissue + systems.
- During or immediately following a single exercise bout.
What is an example of an acute response?
Depletion of ATP.
What is the definition of chronic adaptation?
- Adjustments to repeated exposure to a stimulus result in longer-lasting + systematic changes.
- This influences acute responses + performance over time.
What is an example of a chronic adaptation?
Skeletal muscle hypertrophy
What is Progressive overload?
- Continued application of a training stimulus overtime.
- To an intensity not yet adapted to.
