States that metabolic responses to exercise occur most specifically in those muscle groups being used
Specificity
Type of adaptation will be reflective of
Mode and intensity of exercise
Reflects the importance of incorporating adequate
Mode and intensity of exercise
Reflects the importance of incorporating adequate rest to accompany harder training bouts
Periodization
Resting energy expenditude skeletal muscle
20%
Kcal/min
Human body
70 kg
1.2 kcal/min
Intense exercise
Total energy expenditure
Energy expenditure
15-25x above resting values
18-30 kcal/min
Exercising muscles can inc energy requirements by a factor of
200
ATP skeletal muscles can fuel ___ secs of high-intensity work
5-10 secs
3 metabolic pathways of ATP
Creatinine phosphate system
Rapid glycolysis
Aerobic oxidation
Transfers a high-energy phosphate from creatinine phosphate to rephosphorylate ATP from ADP
Creatining phosphate
Can provide ATP rapid rate
CPS
CPS limitation
Limited supply of CP
CP storage can supply ___ sec of high-intensity work
25 sec
