Increase explosive power: Is it better to have a large weight or a light weight?

The effect of large weight and light weight on increasing explosive power!

　　Is it better to increase explosive power to use large weight or light weight to train?

　　In fact, they have played different roles in enhancing explosive power. This is also the focus of cycle training. All training methods have their meaning at different stages.

　　For increasing the speed and power rate of the entire force performance, training methods for large weight and light weight are necessary.

　　In the first stage, training CNS (central nervous system) can be Recruiting the maximum number of fast-constriction muscle fibers. This usually occurs during the maximum muscle strength period, using more than 70% of the weight of 1RM and explosive movements. The weight of this training will greatly stimulate the neuromuscular system to recruit a large number of fast-constriction muscle fibers.

　　Let us discuss the buffering or conversion stage between centrifugal and centripetal during the stretch-constriction cycle (SSC). From the end of the centrifugal contraction stage to the beginning of the centrifugal contraction action, there is a delay between centrifugal and centripetal. At this time, the Ia type cardiac nerve and the abdomen root of the spine (Ventral) root) α motor neurons are connected, and then the signal is transferred from α motor neurons to the active muscle group.

　　This stage in SSC may be the key to producing a greater explosive force. This period must be as short as possible. If the buffering stage lasts too long, the elastic energy stored in the centrifugal contraction stage will be lost in the form of thermal energy, and the stretching reflex cannot increase the activation of the centripetal contraction stage.
