Strength is the capacity of the musculoskeletal system to develop tension to overcome, oppose, or withstand external resistance.

Question 2

Musculoskeletal Actions
What types of actions must the musculoskeletal system perform?

Answer 2

The system must perform isometric, concentric, and eccentric actions, with dynamic movements occurring at various speeds.

Question 3

How is force related to strength?

Answer 3

Force is the physical influence that can cause an object to move or change its state. Strength is the ability to exert force against resistance.

Question 4
