Your third exercise you select a peak - contraction exercise, which challenges the muscle to
contract against resistance.
PNF (proprioceptive neuromuscular facilitation) stretching is one where muscle group is passively stretched, then isometrically
contracted against resistance while in the stretched position, and then is passively stretched further on.
When a muscle
contracts against resistance it becomes stronger.
Not exact matches
To perform PNF stretching, you need to passively stretch the given muscle, then
contract it in an isometric way
against the
resistance in the stretched position.
When forced and when top one half and one - quarter reps have been completed then
contract isometrically
against resistance to again fatigue the muscles.
The muscle must
contract in order to move the bone that it is attached to or to provide
resistance against a force.
Active Isolated stretching involves having a muscle
contract against some form of
resistance.
While isolating the weak muscle as during muscle testing, the patient is taught to
contract and resist as the practitioner gives verbal cues and the appropriate isometric
resistance against the weak muscle's direction of movement.
Weight training is
resistance training — both isotonic movements (
contracting muscles through a range of motion, like lifting dumbbells) and isometric movements (
contracting your muscles
against each other or a fixed object, like a plank or wall sit.)
-- muscle - building exercises (or a system of muscle - building exercises) involving muscular contractions
against resistance without movement (the muscles
contracts but the length of the muscle does not change)
Now reduce the stretch ever so slightly and begin to
contract the target muscles
against the
resistance being used, increase the contraction from the fourth second until it reaches its peak at 10 seconds and then instantly relax the muscles.
Types of Exercise You want to choose physical activities in which you move
against gravity and your muscles
contract to provide
resistance against your bones.
The only difference is that instead of promoting relaxation to reach your maximum range of movement as you do in passive stretching in isometric stretching you deliberately
contract your muscles
against a form of
resistance for a number of seconds (normally between 8 and 10) to deliberately tire out the muscles and then when you relax you have a short window of opportunity in which you can stretch further before the stretch reflex reasserts itself.
The reason being is that a muscle fiber has tissue with the ability to
contract and expand
against resistance and that is its ability to induce action while using nutrients and body materials as energy sources.
With
contract - relax agonist -
contract (Figure 6), the opposite muscle group (hip flexors) is
contracted against applied
resistance.
