Measuring and evaluating faitgue Flashcards
1
Q
What are the characteristics and main causes of transient fatigue?
A
- Lasting less than 80 minutes and results in decrease in performance
- Main causes are acidosis, substrate depletion, electrolyte disturbance and dehydration
2
Q
What are the characteristics and main causes of acute fatigue?
A
- Fatigue resulting in decrease in performance lasting anywhere between 80 minutes up to 72 hours
- Main causes include micro trauma causes by eccentric muscle actions and blunt trauma causes by contact and collisions
3
Q
What are the characteristics and main causes of chronic fatigue?
A
- Fatigue lasting longer than 72 hours
- Main causes include inadequate recovery, excessive training and playing volume / loads and external factors
4
Q
Should you avoid fatigue?
A
- Should avoid chronic fatigue
- Should not avoid acute and transient fatigue as they are needed to allow for a super compensation causing positive adaptations and allows the athletes to improve
5
Q
When observed what and why are the findings for contact vs non contact lower body neuromuscular function?
A
- Upper body neuromuscular function and muscle damage is lower
- There is a greater decrease in lower body neuromuscular function in non contact
- This is due to an up regulation in running as there is no contact and collisions there will be more distance covered and more time spent running, therefore a greater decrease in neuromuscular function of the lower body
6
Q
Report three ways of measuring post exercise fatigue?
A
- Biochemical
- Neuromuscular
- Hormone/endocrine
- Perceptual
7
Q
Why is creatine kinase used as an indirect marker of muscle damage?
A
- It is found in the cells
- Low circulating ck levels in the blood
- Following muscle damage ck leaks from cells and is found in the blood
8
Q
Report two common lower body neuromuscular fatigue tests?
A
- Countermovement jump
- Sprints
- Cycle ergometer
