Muscular Adaptation structural and architectural changes |
RT increases myofibrial volume, cytoplasmic density, sarcoplasmic ret and t tubule density, and sodium potassium ATPase activity
sprint training enhances calcium release
ressistance training increases angle of pennation |
|
mechanical loading (ML) |
contribution of mechanical forces (pressure, friction, bending) |
|
Bone modeling: |
1. Bone bends due to force 2. Osteoblast lay down additional collagen fibers 3. dormant osteoblast migrate to the straining area 4. collagen fibers become mineralized, and the bone's diameter increases. |
|
Type of bones |
trabecular -cancellous -spongy cortical -compact
|
|
back squat stimulates bone formation in? |
vertebral column and legs but not the wrist
specificity of loading |
|
factors that stimulate bone growth |
intensity
speed of loading
volume
direction of force
|
|
what two training types stimulate bone growth |
aerobic and resistance |
|
how can athletes stimulate bone formation |
exs that directly load particular regions of skeleton
structural exercises
overload the musculoskeletal system and progressively increase the load
vary in exercise selection to change distribution
|
|
improvements in performance from anaerobic exercise |
motor performance aerobic capacity |
|
excessive training on a short term basis |
overreaching |
|
mistakes that can lead to anaerobic overtraining |
chronic use of high intensity/volume or a combination of the two
too rapid a rate of progression |
|
detraining |
strength losses appear related to neural mechanisms intitally, with atrophy predominating as the detraining period extends
amount of strength retained is higher than prevalues
muscle memory may have some validation |
