Q

In advanced lifters,
the CNS might adapt by allowing these well-trained athletes to recruit some motor units in a nonconsecutive order, by recruiting smaller/larger ones first to promote greater production of power or speed in a movement.

Q

Skeletal muscle adapts to anaerobic training and these change result in

A

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

These changes result in
enhanced muscular strength, power, & muscular endurance.

21
Q

Muscle Hypertrophy
is primarily due to an increase in

A

CSA in existing fibers

22
Q

Process of muscle hypertrophy involves an increase in the:

A

net accretion of the contractile proteins actin & myosin within the myofibril.
number of myofibrils within a muscle fiber.
synthesis of structural proteins such as titin & nebulin.

timing of nutrient intake.
mechanical stress of the weight training workout.
muscle cell hydration levels.
anabolic hormonal response.
subsequent receptor response to hormones.

resistance training result in increase in type I, Type II or both muscle fiber area and which one has greater increase in size

A

both, type II

28
Q

Training & activation of high-threshold motor units:
result in the transition of Type IIx muscle fibers to , this mean that a shift of the type of

A

type IIa, this means that a shift of the type of myosin ATPase & heavy chains takes place during training.

29
Q

Resistance training has been shown to:
increase

A

30
Q

The combination of resistance, sprint, & jump training has been shown to:
increase

Sprint & jump training have been shown to:
increase

A

fascicle length in vastus lateralis muscle.

32
Q

Resistance training has been shown to increase

A

myofibrillar volume,
cytoplasmic density,
sarcoplasmic reticulum density,
T-tubule density,
sodium-potassium ATPase activity.

33

34

Heavy resistance training has been shown to:
reduce

A

35
Q

Resistance training has been shown to

A

decrease capillary density
increase resting CP and ATP concentration
increase glycogen content

36
Q

how can athlete stimulate bone formation

A

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.

37
Q

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

A

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.

38
Q

How Can Athletes Stimulate Adaptations in Cartilage?

A

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.
