larger

Skeletal muscle adapts to anaerobic training and these change result in

Answer 20

primarily by increasing its size,
facilitating fiber type transitions, &
enhancing its biochemical & ultrastructural components.

Question 36

how can athlete stimulate bone formation

Answer 36

Select MJ structural exercises that involve many muscle groups at once. Select exercises that direct axial force vectors through the spine & hip. Use the principle of progressive overload to stress the musculoskeletal system. Use both heavy-load exercises & ballistic or high-impact exercises to expose the bone to different intensities of force. Vary the exercise selection to change the distribution of force insults & to present a unique stimulus for new bone formation.

Question 37

How Can Athletes Stimulate Adaptationsin Tendons, Ligaments, & Fascia?

Answer 37

High-intensity exercises (loads) should be used because they markedly change the collagen content of connective tissue. Forces should be exerted throughout the full ROM of a joint. MJ exercises should be used whenever possible.

Question 37

How Can Athletes Stimulate Adaptationsin Tendons, Ligaments, & Fascia?

Answer 37

High-intensity exercises (loads) should be used because they markedly change the collagen content of connective tissue. Forces should be exerted throughout the full ROM of a joint. MJ exercises should be used whenever possible.

Question 38

How Can Athletes Stimulate Adaptations in Cartilage?

Answer 38

Moderate-intensity anaerobic exercise seems adequate for increasing cartilage thickness. Strenuous exercise does not appear to cause degenerative joint disease when progressively overloaded appropriately. Adopt a variety of exercise modalities & ensure that the load is applied throughout the ROM to maintain tissue viability.
