Question 41

Joint angle specificity?

Answer 41

If you only train one specific joint, only those muscle fibers will be stimulated to adapt and develop strength in that ROM.
For all muscle fibers being worked to improve all around strength, multiple joints should be trained to increase muscle fibers activated during the movement.
Layman’s terms: the muscle will only adapt to the respective joint angle(s) in which the muscle is being activated.

Question 42

How does joint angle affect exercise selection?

Answer 42

depending on the angle in which the muscles are being worked, muscles may be stronger at one specific angle compared to another.
Being able to demonstrate increased strength at multiple joint angles allows for versatility.
ex. only practicing wide grip bench press, but struggling to increase normal grip bench press.

Question 43

Characterize Concentric muscle action and sport relationship

Answer 43

Muscle shortens b/c contractile force is greater than resistive force.
Forces generated within muscle and acting to shorten it are greater than the external forces acting at its tendons to stretch it.
Agonist muscle is shortened and elastic energy generated from eccentric phase is released.
SR: demonstrate improved ability during acceleration movements.

Question 44

Characterize Eccentric muscle action and sport relationship

Answer 44

Muscle lengthens b/c contractile force is less than the resistive.
Forces generated within muscle and acting to shorten it are less than the external forces acting at its tendons to stretch it.
SR: demonstrate improved ability during deceleration movements.

Question 45

Characterize Isometric muscle action and sport relationship

Answer 45

Muscle length does not change, b/c contractile force is equal to resistive force.
Forces generated within muscle and acting to shorten it are equal to external forces acting at tendons it.
SR: improved elasticity and strength maintenance.

Question 46

How does the force-velocity curve impact exercise selection?
https://www.scienceforsport.com/force-velocity-curve/

Answer 46

depending on the training goal (e.g. strength or power), higher required force = lower velocity and vice versa.
If only one side of the curve is trained, the other while be reduced (e.g. only training max strength improves force production, but reduces muscle contractile velocity).
Increased force (strength) shifts right while speed (velocity) shifts left.
Increased speed shifts right while force shifts left.
