ATP high intensity intermittent exercise and team sports

Question 1

Team sports characteristics

Answer 1

long overall durations of effort 
multiple sprints 
repetitive 
unpredictale 
variable

Question 2

Energy system involvement in team sports

Answer 2

Repeated back to back hard exercise
Contributions of anaerobic glycolysis declines
Relative contributions of PCr and oxidative metabolism increase
Exercise model generalisable to team sports
PCr reynthesis after high intensity exercisee

Question 3

Fatigue

Answer 3

First bout of exercise- capacity for using PC system using 35% faster in type 11
Short term fatigue in repeated sprints is related to depletion of type 11pcr

Question 4

HIIT

Answer 4

enhanced form of interval training
tried high intensity anaerobic exercise (for 85% to 250% VO2 max for 6 seconds to 4 mins)
Separated by brief but slightly longer bouts of low intensity aerobic rest (from 20% to 40% vo2 max for 10 seconds to 5 mins)
