Resistance Training Principles

Question 1

Overload

Answer 1

In order for muscle to become stronger, load placed on it must be greater than what it is normally accustomed to.

Question 2

SAID principle

Answer 2

Specific adaption to imposed demands. Body will adapt according to specific type of training. Training needs to mirror specific goal.

Question 3

Transfer of training

Answer 3

There can be carryover effect from one exercise or task to another. For example, an exercise for strength can also improve endurance.

Question 4

Reversibility

Answer 4

Adaptions seen with strength training are reversible if the body is not regularly challenged with the same or greater level of resistance. These effects begin within 1-2 weeks of stopping an exercise program.

Question 5

Length-tension relationship

Answer 5

Ability to produce force depends on length of the muscle. If muscle is lengthened or shortened, it will produce less force.

Question 6

Force-velocity relationship

Answer 6

Speed of a muscle contraction affects the force that the muscle can produce. During a concentric contraction, as the speed of contraction increases, the force of contraction decreases. During an eccentric contraction, as the speed of contraction increases, the force of contraction also increases.
