Post Content
Chapter Goals:
- Describe the functions of activation techniques in programs for corrective exercise.
- Find the techniques for activation for use in programming the corrective exercise.
- Describe the guidelines of application for the techniques in activation.
Introduction
Phase one and two of the continuum addressed the overactive and the shortened myofascial tissues that restrict our range of motion in the joints and end up decreasing our ability to move.
The third phase is going to be activation.
This refers to the stimulation of the underactive and the lengthened myofascial tissues.
Due to the impairments present in the human movement system, we must address these underactive muscles after finding the ones that are shortened and overactive.
Isolated Strengthening
These exercises are used for isolating certain muscles for increasing the production of force capabilities through the use of concentric and eccentric actions.

We apply these exercises to the underactive muscle through the process of assessment.
Scientific Rationale for Isolated Strengthening
This is a technique used for increasing the intramuscular coordination of specified muscles.
We achieve this through the combo of enhanced motor unit activation, synchronization, and firing rate.
Synchronization is the synergistic activation of multiple motor units.
Firing rate is the frequency to which the motor unit is activated.
Motor unit activation is the progressive activation of the muscle by successive recruitment of contractile units for the accomplishment of increasing gradations of contractile strength.
Each of the previous parameters have been found to increase the strength of a muscle contraction.
And we develop intramuscular coordination through traditional resistance exercises that focus on specific muscles.
It is important for us to achieve increased activation of the specific muscle prior to integrated exercise, so that we can avoid synergistic dominance.
Isolated strengthening can be done immediately following the inhibition and lengthening techniques.
There is no actual research supporting this, but it has clinically shown the results we are looking for.
Mennell’s Four Basic Truisms
1: when a joint is not free to move, the muscles that move it cannot be free to move it.

2: Muscles cannot be restored to normal if the joints that they move are not free to move.
3: normal muscle function depends on normal joint movement.
4: impairments in the function of muscles perpetuates and may even cause deterioration in abnormal joints.
When doing isolated strengthening exercises, it is important that we emphasize the eccentric portion of the moves, as these slow tempo eccentrics have beneficial physiological and mechanical properties.
It is also shown that these help in times of needed recovery for muscle injuries.
Another important note is that eccentric focused exercise has been associated with muscle damage and increases in delayed onset muscle soreness.
Precautions and Contraindications for Activation/Isolated Strengthening
Precautions for Isolated Strengthening
- Special populations
- Neuromuscular disorders
- Clients that have poorer core stabilization strength
Contraindications for Isolated Strengthening
- Acute injuries or muscle strains or tears of a muscle that is to be stretched
- Acute rheumatoid arthritis of the joint that is affected
- Impairments in the motion of the joint
- Pain found when doing the movements
Acute Training Variables for Isolated strengthening
- The frequency should be 3 – 5 days per week
- The sets should be in 1 – 2 sets
- Repetitions are 10 – 15 reps per set
- The duration of the reps is described as a 4/2/1. This means four seconds for the eccentric portion, 2 seconds for the isometric hole at the end, and then lastly the one second for the concentric contraction.
