The elemental notion
of god - bearing individuals may be spoken
of in an ontological sense when one perceives a sense in which the individual's personality appears to alter or fuse in those «abnormal» «
eccentric»
phases to effect specific outcomes for «the individual in a community
of faith» or for the community
of faith extraneous to the individual.15 When the fusion
of the individual's personality with the alleged divine being is complete and permanent, such an individual may be said to have actualized the ideal state
of union with the divine, which may be reversible or irreversible state
of being.

There are 3
phases of muscle activity when doing an exercise: concentric (when the muscle shortens), isometric (when the muscle is static and held in place under tension) and
eccentric (when the muscle lengthens).

phases of a lift, and those are: the concentric part, isometric part, and the
eccentric part.
«Building momentum by swinging your arms when doing a move like a bicep curl or a tricep push - down sacrifices results by not controlling the
eccentric phase, and also increases your risk
of injury,» says Irv Rubenstein, PhD, exercise physiologist and founder
of STEPS Fitness, a science - based fitness facility in Nashville, Tenn..
You can place them at the beginning
of your chest or triceps routine and perform a lower number
of reps with emphasis on the
eccentric phase, or you can use them as workout finishers and get a great final pump!
For example, when you do the squat, the
eccentric phase is when you lower the bar to the bottom
of the squat position, and the concentric
phase is when you push it back up.
During the downward portion
of the movement (
eccentric phase) the musculature
of the anterior deltoids (shoulder) and pectoralis major (the pecs) along with your core are activated.
Kettlebell swings are ideal for strengthening the posterior chain because
of the way their
eccentric phase increases innervation
of intrafusal muscle fibers.
The muscle can produce and sustain more tension during the lengthening (
eccentric)
phase of the exercise, which increases the chances
of a strain occurring.
Eccentric --(Negative) The lowering
phase of an exercise, when the muscle lengthens.
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.
The first number is the
eccentric or lengthening
phase of the exercise.
The
eccentric phase (muscle stretching)
of any exercise is when most
of the muscular damage occurs and the main cause
of post-training soreness.
When you perform the
eccentric phase, stretch the muscles as far as possible without letting the shoulders round or the spine move out
of position.
With efficient
eccentric isometrics, focusing on concentric positioning is almost unnecessary as the muscles have been properly activated on the lengthening
phase and will stay so throughout the rest
of the movement / shortening
phase.
A plyometric effort is, when the body makes use
of the so called stretch - shortening cycle where the muscle is rapidly stretched in the
eccentric phase, followed by a rapid shortening
of the muscle in the concentric
phase.
On the muscular system, because the
eccentric phase is done with additional loads, on the nervous system, because there is a potentiation effect when you let go
of the dumbbells and the nervous system sends a stronger signal to the muscle fiber to fire.

of time during the
eccentric and concentric
phases of your lifts.
Tempo Changes: Change the amount
of time during the
eccentric and concentric
phases of your lifts.
Many
of these reviews have discussed the unique effects
of eccentric training, which seem to arise from the differences between
eccentric and concentric
phases of an exercise.
Increasing muscle fascicle length through
eccentric training could therefore be a valuable method for improving athletic performance in movements that have peak contractions at long muscle lengths, such as the terminal swing
phase of sprinting, or the ground contact
phase of sharp change
of direction (COD) maneuvers.
This means that force production is greater (and more efficient) in the
eccentric phase than the concentric
phase, because passive elements resist lengthening
of the muscle fibers in the
eccentric phase, but not in the concentric
phase.
Eccentric training is strength training using only the lowering
phase of an exercise.
In contrast, with the same absolute load (load lifted in both movements equal to 90 %
of overhead squat), there was no difference in gastrocnemius muscle activity during the concentric
phase yet greater muscle activity during the
eccentric phase when performing the overhead squat.
When training with plyometrics (or any
of the other power strategies you're about to discover), the delay between the stretching,
eccentric phase, and the shortening, concentric
phase needs to be very short — no longer than about a quarter
of a second.
• 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.
As far as the brain is concerned, the concentric
phase of movement is different from the
eccentric and isometric
phases of lifting, yet we all measure strength by how much an athlete could concentrically move!

eccentric (lowering)
phase of resistance training leads to the lion's share
of the overall training stimulus, especially regarding hypertrophy.

phase (holding
phase) and then take 4 seconds to lower the weight (the
eccentric phase — lengthening
of the muscle) and then pause for 1 second.
