|
|
Term
|
Definition

|
|
Term
|
Definition

|
|
Term
|
Definition
| the amount of the tension produced by the muscle is constant but the length of the muscle changes |
|
|
Term
|
Definition

|
|
Term
|
Definition
| decreased capacity to do work and reduced efficiency of performance |
|
|
Term
|
Definition
