lecture 34 Flashcards
when is peak physiological performance
20s
why are we strongest at 20
muscle cross section area at largest
what is the LTAD model
diagramed when qualities or specific skills should be targeted
when does LTAD and YPD say you should target endurance
LTAD : 12F and 14M
YPD: 18+
when does LTAD and YPD say you should target speed
LTAD: two diff. 6F, 7M or 11.5F and 13M
YPD: less focus post adolescene phase.
when does LTAD and YPD say you should target power/strength
LTAD: after growth spurt
YPD: equal focus all ages (except young children)
when does LTAD and YPD say you should target agility
LTAD: 5-11F, 6-12M
YPD: reduced focus early childhood late adolescene
when does LTAD and YPD say you should target skill
LTAD: 8-11F, 9-12M
YPD: FMS> focus before 8F, 9M
SSS> focus adolescene
key ideas of LTAD
10,000 hours or 10 years
crictical and sensitive periods exist which accelerated adaptation can take place.
early and late specialisation in sports
ypd key ideas
constraints based approach
no focus on endurance until adulthood
nine physical qualities included.
what happens when we get older
regression
genetic regression theory
aging controlled by genes
regression - wear and tear theory
repair cannot keep up with damage
regression - immune system theory
ability to fight infection is reduced with regression.
hormonal theory of regression
atrophy of the thymus gland influences immune function. decrease in oestrogen and growth hormone also influential.
