Strength Training

Question 1

What is strength

Answer 1

The ability to apply at force

Question 2

What is static strength

Answer 2

The ability to apply a force against a resistance without any movement occurring (isometric contraction)the muscle length remains constant.

Question 3

What is dynamic strength

Answer 3

The ability to apply a force to overcome a resistance where movement occurs (isotonic contraction)the muscle length changes

Question 4

What is strength endurance

Answer 4

What the ability to sustain repeated muscular contraction s (or a single isometric contraction over a period of time)

Question 5

What are the factors that affect strength

Answer 5

The muscle fibre type being recruited and the cross sectional area of the muscle

Question 6

How does the muscle fibre type that is recruited affect strength

Answer 6

Fast glycolytic muscle fibres exert greater force with a greater speed of contracts than other fibre types
Motor units consisting of FG fibres are large(with up to several hundred fibres) and have lager motor neutrons than so motor units `, which send faster impulses, these units have the highest explosive and maximum strength.

Question 8

How does the cross sectional area of the muscle affect strength

Answer 8

The larger the cross sectional area of the muscle, the greater the strength or force of contraction
Age, gender and training all affect the cross sectional size of the muscle.
