L9, Specificity of Strength Training

Question 1

What is strength?

Answer 1

How much force can be produced with the muscle we have

Question 2

What are the 6 strength and power components?

Answer 2

• Force
• Work
• Torque
• Power
• Endurance time
• ROM

Question 3

What is reactive strength?

Answer 3

The combination of eccentric and concentric strength. The athlete must overcome negative momentum before reversing the movement to generate force in a positive direction.

Question 4

What is muscle activity principle 1?

Answer 4

Direction of movement determines the type of activity we see

Question 5

What is muscle activity principle 2?

Answer 5

Muscle and tendon can have different actions

Question 6

What is muscle activity principle 3?

Answer 6

• Mechanical force is non-linear over muscle range of length
• Isotonic (uniform) muscle force does not exist in human movement

Question 7

What is muscle activity principle 4?

Answer 7

• Not all muscle actions involve contraction

(Eccentric movement still involves muscle action, but it is not a contraction)

Question 8

What is muscle activity principle 5?

Answer 8

Isokinetic= Constant rate of movement

(Does not occur in sports skills, sport skills are complex and nonlinear)

Question 9

What is contraction?

Answer 9

The process of becoming shorter

Question 10

What 3 phases make up the stretch-shortening cycle

Answer 10

• Eccentric phase
• Isometric phase
• Concentric phase
