Fatigue

Question 1

fatigue?

Answer 1

gradual and multifactorial process.

Question 2

fuel depletion

Answer 2

depletion of the body’s energy fuels which allows ATP resynthesis to occur

Question 3

central fatigue?

Answer 3

occurs when muscular function is decreased due to CNS.

Question 4

peripheral fatigue?

Answer 4

at the muscles, when muscle function is disrupted.

Question 5

Factors that affect the rate of fatigue?

Answer 5

• type of activity
• intensity
• fitness levels

Question 6

factors contributing to fatigue?

Answer 6

thermoregulation
fuel depletion
by products

Question 7

Anaerobic system likely cause of fatigue

Answer 7

lactic acid - impaired muscle contraction force, impaired velocity force
accumulation of H+ ions - makes muscles more acidic,

Question 8

Aerobic system likely causes of fatigue

Answer 8

fuel depletion - moving from glyocgen to fats, meaning you will hit the wall for energy supply
thermoregulation - evaporation sweat produced trying to cool the body results in reduced muscle strength and endurance, convention, radiation
neuromuscular factors - decreased CNS firing, weaker signals to working muscles reducing intensity and slow down work rate, loss of electrolytes, DOMS
