1. Field Hockey Physiology By Margaret Winter

2. 80% of field hockey is aerobic & 20% is anaerobic (2) Stick skills and semi-crouched running with stick increases energy expenditure (4) Anaerobic systems needed for changes in motion that occur every 5.5 sec (6)

3. Field hockey is an intermittent sport  Often changing between aerobic and anaerobic movements  Shuttle tests are good for field hockey because they simulate game like movement (2)  Lactate in blood after tests  VO 2 max increases with training (1)

4. Summary  FH mostly aerobic (frequently running/walking)  ATP-PC for stick work and changing direction  Glycolytic for longer sprints and repeated sprints
