SSC is characterized by lengthening the muscle (plyometric exercise) immediately
following a muscle contraction (weight training exercise).
This store of phosphocreatine is also replenished by the mitochondria
following muscle contraction and a measure of mitochondrial efficiency is the time taken for replenishing these stores: better mitochondrial function is linked to shorter times of phosphocreatine recovery.

A tiny quiver in the joint
followed immediately by an extension and
contraction of the
muscle being worked.
The cyclists in the Montmorency tart cherry group maintained
muscle function (as measured by maximum voluntary isometric
contraction) and experienced a reduction in certain inflammatory responses
following the simulated cycling race, compared to those consuming the placebo drink.
They
follow individual proteins in clusters of stem cells, trace cellular migration in a developing fruit fly larva, and observe
muscle contractions in a nematode embryo (see video, above), among other tasks.
In addition, the altered rates of force development and relaxation suggest alterations in the regulation of intracellular calcium levels
following maximal
contractions, as are noted to occur in slow skeletal
muscles (44).
Following isometric
contractions, the
muscles remained in oxygenated Ringer's for 5 minutes prior to the repeated - stimulation fatigue protocol.
Priometric exercises are a combination of involuntary reflex
followed by rapid volitional
muscle contraction.
The downward phase of a push - up involves an eccentric
contraction of the chest
muscles, which is immediately
followed by a strong concentric
contraction to push back up and clap the hands.
As such it is a powerful method to relax
muscle contraction and inflammation
following exercise.
For example, during the
follow through of a baseball pitch, the involved
muscle groups must provide important decelerative
contractions to preserve healthy arthrokinematics (joint functioning).
• Takes advantage of the stretch shortening cycle → Uses energy stored by eccentric
muscle contraction (lengthening phase) quickly
followed by concentric
muscle contraction (shortening phase) to generate high amounts of power.
During the stretch - shortening cycle a
muscle gets stretched or lengthened (eccentric
contraction),
followed by an instant shortening (concentric
contraction).
The cyclists in the Montmorency tart cherry group maintained
muscle function (as measured by maximum voluntary isometric

Proprioceptive neuromusclar facilitation, or PNF for short, «uses the nervous system by involving a
contraction against light resistance,
followed by release of the
muscle,» says Campbell.
However, isometric force is greater than expected when
contractions follow eccentric
contractions compared to when they
follow concentric
contractions at the same
muscle length (e.g. Morgan et al. 2000).
More specifically, most PNF stretches involve a shortening
contraction of the opposing
muscle followed by an isometric
contraction of the target
muscle.
With contract - relax (Figure 5, top), the stretched target
muscle group (hamstrings) is placed into a static
contraction,
followed by a relaxation.
Suppose that, in accordance with this view, each
muscle were to maintain that the nervous system had no right to interfere with its
contraction, except to prevent it from hindering the
contraction of another
muscle; or each gland, that it had the right to secrete, so long as its secretion interfered with no other; suppose every separate cell left free to
follow its own «interest,» and laissez - faire lord of all, what would become of the body physiological?
