Question

2. For the exercise below, write the type of contraction (isometric, concentric, eccentric) if any, in the space of the muscle group that is contracting. Place a dash in the space if there is no contraction occurring. (Hint: you may have more that once type of contraction in the same muscle group through varying portions of the exercise. If so, list them in the order of occurrence.

Stand on one leg and move the other knee as directed:

Exercise	Quadriceps	Hamstrings
Maintain your knee in full extension
Very slowly flex your knee maximally
From the fully flexed position, slowly extend you knee fully.
From the fully flexed position, extend your knee fully as fast as possible.

Answer 1

Isometric contraction - It is a type of muscle contraction in which there is no change in the length of the muscle fibres while undergoing tension

Eccentric contractions- It is a type of muscle contraction when the length of the muscle elongates or lengthens while undergoing tension

Concentric contractions- it is a type of muscle contraction when the length of the muscle shortens while undergoing tension

Exercise	Quadriceps	Hamstrings
1.	Isometric	Passive
2.	Eccentric	Concentric
3.	Concentric	Eccentric
4.	Concentric	Eccentric
