understanding adaptations

Question 1

physical stress theory

Answer 1

OVERLOAD - injury
increased tolerance - adaptation
maintainence
decreased tolerance - atrophy

Question 2

what drives adaptation

Answer 2

• type of force
• magnitude of force
• drequency of force

Question 3

envelope of function

Answer 3

The envelope can represent the upper limits of performance, such as the maximum strength or endurance a person can achieve during workouts.
- above zone of surpaphysiological overload + zone of strutual failure
- below negative adaptations + disuse

Question 4

what can change envelope of function

Answer 4

exercise has the potential to increase the envelope of function.

Injury and illness reduces the envelope of function.

Question 5

capacity v tolerance

Answer 5

Capacity – limits structurally (tissue/system)
Tolerance – how much are you willing to deal with

Question 6

Wolff’s law

bone adaptations to imposed mechnical loading

Answer 6

• when stress/strain is applied to our bones they remodel
• stress is force applied to a tissue, while strain is the amount of deformation (distort, twist, buckle, bend) that occurs in the tissue.
• stress and strain applied to bones = thicker, stronger bones. If stress and strain is not applied bones become thinner and weaker.
