| Concentric | When a muscle exerts more force than is being placed on it, which leads to the shortening of the muscle |
| Length-tension relationship | Refers to the length at which a muscle can produce the greatest force |
| Force-couple | synergistic action of muscles to produce movement around a joint |
| Proprioception | Information that the nervous system utilizes to gather information about the environment to produce movement |
| Sensorimotor integration | ability of nervous system to gather and interpret information and select and execute the proper motor response |
