Q

Connective tissue increases in size and strength are contributed by what factors?

A

Increase in collagen fibril diameter
Greater number of covalent cross links within the hypertrophied fibre
Increase number of collagen fibrils
Increased packing density of collagen fibrils

17
Q

An increase in the size and strength of connective tissues through the contributing factors does what as an overall positive?

A

Increases tendon stiffness which aids increasing ground reaction force.

18
Q

What intensity of exercise needs to be performed to stimulate connective tissue adaptations?

A

High intensity - results in net growth of connective tissue.
