Theories & Methods of Coaching Weight Training

When weight is being lifted, major muscles involved are shortening 

When weight is being lowered in controlled manner, major muscles involved are developing force and lengthening 

When muscle is activated and develops force but no visible movement at the joint occurs.

One complete motion of an exercise.

Consists of two phases:

Concentric muscle action- lifting

Eccentric muscle action- lowering of resistance

Group of repetitions performed  continuously without stopping or resting

Typically range from 1-15

Maximal number of repetitions per set that can be performed in succession with proper lifting technique using a given resistance

Heaviest resistance that can be used for one complete repetition of an exercise 

Maximal amount of force a muscle or muscle group can generate in a specified movement pattern at a specified velocity

Force multiplied by the distance a weight or resistance is moved.

Can be increased by increasing the distance a weight is moved or increasing the weight or resistance being moved

Is the rate of doing work (work/time)

Can be increased by increasing the distance a weight is moved or increasing the weight or resistance being moved or by decreasing the time in which a certain amount of work is performed

Is a measure of the total amount of work (in joules) performed in a training session, a week of training, a month of training, or some other period of time. 

between sets of an exercise, between exercises, and between training sesssions allow recovery and are important for success of any program

Concept that resistance training produces its greatest strength and power gains at velocity at which training is performed
