3. What is fatigue????

4. Type
1. Local fatigue
2. General fatigue
22-Sep-14 4

5. Fatigue Assessment
1. Local assessment
2. Systemic assessment

6. 1. Local assessment:
• Muscular fatigue
• Fall strength or firing ability of the
muscle fiber determine fatigue.
22-Sep-14 Fatigue Assessment: Local assessment 6

7. 1. Local assessment: contd..
• Commonly used techniques
follows:
1.Electrophysiological testing:
2.Decremental studies
3.EMG
4.MMT:
5.Endurance testing:
22-Sep-14 Fatigue Assessment: Local assessment 7

8. a) Decremental studies
• Repetitive stimulation of the all muscle
fibers.
• Supramaximal stimulation
22-Sep-14 Fatigue Assessment: Local assessment 8

9. b) EMG
• Voluntary muscle contraction
22-Sep-14 Fatigue Assessment: Local assessment 9

10. c) MMT
• Fatigue the strength generated by
muscle decrease.
22-Sep-14 Fatigue Assessment: Local assessment 10

11. d) Endurance testing:
• Ability to work without rest
• Tendency of the muscle to develop
fatigue.
22-Sep-14 Fatigue Assessment: Local assessment 11

12. 2. Systemic assessment:
a) Anaerobic assessment
b) Measurement of blood lactate level.
c) Measurement of aerobic capacity.
d) Measurement of energy
expenditure.
Fatigue Assessment: Systemic assessment
22-Sep-14 12

13. a) Anaerobic fatigue:
• The hydrogen oxidation in respiratory
chain.
• Anaerobic glycolysis
• lactate accumulates in active muscle
and blood.
• Anaerobic fatigue and Rate of fatigue
22-Sep-14 Fatigue Assessment: Systemic assessment 13

14. a) Anaerobic fatigue: contd..
Test:
1. Katch test
2. Wingate cycle ergometer test:
Fatigue Assessment: Systemic assessment
22-Sep-14 14

15. a) Anaerobic fatigue: contd..
Katch test:
• Time: 40 sec
• Load :
• Anaerobic power:
• Anaerobic fatigue:
Fatigue Assessment: Systemic assessment
22-Sep-14 15

16. a) Anaerobic fatigue: contd..
Wingate cycle ergometer test:
• Very popular and latest test.
• Anaerobic power , fatigue and total
anaerobic capacity.
Fatigue Assessment: Systemic assessment
22-Sep-14 16

17. a) Anaerobic fatigue: contd..
WCET procedure:
Fatigue Assessment: Systemic assessment
22-Sep-14 17

18. a) Anaerobic fatigue: contd..
Test score:
 Peak power output:
 Anaerobic fatigue:
Fatigue Assessment: Systemic assessment
22-Sep-14 18

19. a) Anaerobic fatigue: contd..
 Peck power output:
PPO=force *distance/time
• {no of revolution*distance of
revolution}/time(min)
• 5 sec = 0.0083 min
Fatigue Assessment: Systemic assessment
22-Sep-14 19

20. a) Anaerobic fatigue: contd..
 Anaerobic fatigue:
• Total capacity to produce ATP
• AF = [highest 5 sec pp – lowest 5
sec pp]/highest 5 sec pp*100
Fatigue Assessment: Systemic assessment
22-Sep-14 20

21. b) Measurement of blood lactate level
• Anaerobic metabolism to give
energy.
• Lactate levels reach maximum.
• Energy storing and generation
pathway
Fatigue Assessment: Systemic assessment
22-Sep-14 21

22. c) Measurement of aerobic capacity
• Lack of proper oxygen supply
• Long exercise during programmers.
• Maximal oxygen consumption which
is given by vo2max.
• Measured valve =ml/kg/min
Fatigue Assessment: Systemic assessment
22-Sep-14 22

23. • Fick equation:
Vo2max= cardiac output *arteriorvenous O2 diff
(HR*SV) (Art O2-ven O2)
= Q*(a-v)O2
22-Sep-14 Fatigue Assessment: Systemic assessment 23

24. d) Measurement of energy expenditure
• Open circuit portable spirometry
and telemetry.
• Spirometry testing:
• Telemetry or physiologic radio
transmission:
