fatigue and recovery
causes (muscular fatigue)
depletion of energy sources- glycogen, phosphocreatine
increase in acidosis due to lactic acid, hydrogen ion and carbon dioxide build up- decreased enzyme function
accumulation of waste products
dehydration
electrolyte
causes (neuromuscular fatigue)
depletion of acetylcholine (ach)-
decrease calcium ion release- allow for actin and myosin to bind together
key principles
restoration of phosphagen stores (ATP and phosphocreatine)
removal of lactic acid
replacement of glycogen
replenishment of myoglobin stores with oxygen- found in heart and skeletal muscles
EPOC
fast components
slow components
restoring ATP and creatine phosphate as quickly as possible
during first 3 minutes
99% of ATP and creatine phosphate are restored that have been used during exercise
the amount of oxygen required to remove lactic acid from muscle cells and the blood
can take several hours
intensity of exercise
active or passive recovery?
