D3 - Forcing the issue Flashcards
What is the best way to train the productive application of force?
The best way to train the productive application of force is through functional movements
How is power calculated according to the provided information?
Power is calculated using the formula Power = Force x Distance over Time.
What prevents injury when facing large compressive forces during exercise?
Proper exercise technique in the face of large compressive forces prevents injury because it allows bones to support the weight
What is an additional perk of bone-on-bone movement?
Bone-on-bone movement provides more effective force transfer as an additional perk.
What happens when exercises with compressive characteristics are done progressively?
When done progressively
How does tension relate to hanging on a high bar?
If someone hangs on a high bar
What represents a safeguard against extreme joint movement?
Ligaments represent a safeguard against extreme joint movement
What occurs with regular progressive performance of exercises that produce tension?
Regular progressive performance of exercises that produce tension results in gains in tolerance as the loaded ligaments become stronger and thicker.
Why is torsion (torque) considered a normal part of human activities?
Torsion (or torque) is considered a normal part of human activities
What problems can arise from applying torsion to joints not designed for rotational movement?
Applying torsion to joints not designed for rotational movement can lead to problems
What is the distance between the point of resistance and the point of force application called?
The distance between the point of resistance and the point of force application is called a moment arm.
When is shear force present in the body?
Shear force is present when one segment of the body has a force applied to it in one direction
Why are exercises for vertebral column stabilization important?
Exercises directed at the development of the musculature that accomplishes vertebral column stabilization are important for fitness
What is tested by leg extension and leg curl exercises?
Leg extension and leg curl exercises
What is the difference between a balanced force across a joint and a strength balance between agonists and antagonists?
A balanced force across a joint is not the same as a strength balance between agonists and antagonists. A precisely balanced force across a single joint would result in an isometric muscle action and not move. Antagonist muscles are not recruited extensively or are inhibited in force production to allow the agonist to drive movement.
