Full Extension, Maximum contraction For Muscle Stimulation
Eccentric
- Movements
- Slower
- Full extension
Tempo is slower on the eccentric or negative phase of the rep.
Concentric
- Faster
- Movements
- Full contraction
Tempo is faster than negative phase of rep, for example 3 secs.
Maximum
- Max Fibers used
Using as many of your muscle fibers all at once to apply force in the same direction.
Muscle fibers are binary meaning that they either contract/fire or they don’t – there’s no such thing as a partial contraction, or partial firing. Thus, the most important factors in determining power output are the types of muscle fibers you fire and the number of motor units used.
Â
Doing full range movements, with slower negatives and full hard contraction at end of the positive phase of a repetition can go a long way to recruiting more muscle fibers and breaking down tissue.
With rest / recuperation and proper nutrition muscle growth will take place.
