Physical literacy assessment for youth

Valid and reliable

24
Q

Peak pur

A

Highest mechanical power that is generated during exercise Los

25
Q

Mean power

A

Aug mechanical power that is generated during 30 seconds of a task

26
Q

Reasons why anaerobic performance is lower in children

A

Smaller muscle mass → ability to produce power, typ I fibers i in children
Lower glycolytic activity→ difference in alycolutic storage is 50%- lower in kids

27
Q

How can we asses glycogen utilization

A

Max blood lactate
Ph
Baseline/resting quyrogen
Muscles can’t butter h’ ions and ph falls to 6.3

28
Q

How Pa helps brain

A

Change structure
Greater brain volume in hippo and basal ganglia
Quay matter
Communication between white and quay
Active kids can switch on regions for high level thinking
