Lecture #7

Question 1

Isometric Contractions

Answer 1

Static contractions
Active tension developed but joint angles remain constant

Question 2

Concentric Contractions

Answer 2

Muscle shortens as it develops active tension
Muscle develops enough force to overcome applied resistance
Movement and Resistance diff directions

Question 3

Eccentric Exercises

Answer 3

Muscle lengthens under active tension
Force development by the muscle is less than that of the resistance
Movement and resistance same direction

Question 4

Passive Exercises

Answer 4

Movement may occur at any given joint w/out muscle contraction

Question 5

Isokinetic Exercises

Answer 5

Dynamic exercises using concentric and/or muscle contractions
Muscle contractions occur throughout movement
