Based on your sport demands learn how to engage your kinetic chains effectively
Every muscle in our body is chained to the rest. In a movement, some act as Prime movers, others as Antagonists, or Synergists. The main effect this chaining has on our body is counterbalance.
The strength and flexibility of every muscle is less a determinant for faster a response than it is a healthy nervous system. Motor neurons are responsibles for muscle contractions. So focus and channel your nervous energy.
That mysterious force that keep us attached to Earth. Instead of fighting it we should see it as our ally. We can use our weight aligned with the vertical force of gravity as the initiator of a particular movement.
We are a bipedal species. However we tend to favour more one side than the other; which causes imbalances in our body. These are only noticeable when we want to reach to Elite level. Why to wait until then to make corrections...
Allowing our bodies to continually perform high demand activities from a predominant unilateral control might result in injuries. We should spend longer time training our weaker side to counteract this tendency.
If one of our sides is much weaker than the other we will get tired much faster. The amount of stress we have to deal with when the body senses tiredness is tremendous, which makes us even more tired.
Eccentric and concentric training offers different advantages to the participant. The timing and intensity exerted in the Eccentric phase can bring a new dimension to the Skeletal Muscle kinetic chain.
Overloading the kinetic reaction in the eccentric phase will increase its response during the concentric phase. This is due to the fact that during the eccentric phase active and passive elements of muscle fibers are both engaged.
The main gain for training the kinetic chain during the eccentric phase is endurance for the muscles involved learn to be more efficient as more fibres are recruited to perform a movement.
The advantages of this approach are numerous. Gain in high-velocity strength, muscle size, increase of collagen expression, increase on lateral force transmission, neural adaptations and voluntary activation improvements.
