Fatigue and Recovery process
- Fatigue and factors that can cause it.
- A reduced capacity to complete work brought about
by a lack of oxygen, energy or muscle tiredness
- depletion of fuels; fats,
carbohydrates, proteins
- Depletion of muscle glycogen stores
- Accumulation of waste products
- A reduced capacity to complete work brought about
by a lack of oxygen, energy or muscle tiredness
- Centeral governor theory
- theory suggests that fatigue is an
emotional response by the brain to
stop muscles from being exhausted
- The role of lactic acid in the fatiguing process;
does not intially impair performance but instead
provides a fuel source for working muscles.
However continued production of lactic acid
increases the pH of the blood/ muscle cells and
eventually causes exercise to stop.
- Muscle fibre
recruitment; current
research shows that
the body does not
recruit more muscle
fibres as fatigue sets in
- Muscle glycogen depletion; shows that
muscles never totally run out of glycogen
stores during exercise. this fatigue can
be delayed by teaching the Centeral
Governor that going fater wont do the
body harm
- Also a link with dehydratin
and temperature regulation
- theory suggests that fatigue is an
emotional response by the brain to
stop muscles from being exhausted
- Process of recovery/EPOC/DOMS
- Two phases of recovery; fast
component and slow component
- Fast component; concerned with
restoration of muscle phosphagen
stores and takes up to four minites
- Slow component; this is the process
of returning the body to pre-exercise
condition; including heat dissipation,
energy replenishment, rehydration
and removal of lactic acid
- Fast component; concerned with
restoration of muscle phosphagen
stores and takes up to four minites
- Excess Post
Oxygen
Consumption
refers to elevated
ventialtion and
breathing rates
after exercise
- Cool Down; significantly increase recovery time. Light exercise keeps
capillaries dilated to oxidise lactic acid and remove waste product
- DOMS; muscle stiffness after exercise. Caused by microscopic tears
and trauma to muscles from high intensity training. This can be
minimised by buillding training intensity gradually, cross training
- Two phases of recovery; fast
component and slow component
