Increase the load to make the muscles more powerful
After a survey of regular fitness groups, the researchers found that if the weight of the training is relatively light, the length of exercise in the muscle and there is not much difference. However, those heavy-duty people, than light-weight people, can better gain power.
In order to understand the reasons, the researchers selected 26 men, the use of leg stretching machine, carried out a six-week training. The final results show that, regardless of light load, or heavy-duty participants, muscle growth are almost the same. But the heavy-duty participants, muscle strength increased by about 10 pounds. In other words, that is, both sides grow the same volume of muscle, but the heavy load the muscles of the participants more powerful.
Stimulate nerves to make exercise more effective
In order to understand the role of nerves in building power, the researchers provided current to stimulate the muscles of the participants' leg muscles. Researchers eventually found that light-weight participants increased their neurological capacity from 90.07% to 90.22%. While the heavy-duty participants rose from 90.94% to 93.29%, a full increase of 2.35%. This suggests that weight-bearing training does help to improve the efficiency of peripheral nerve cells in muscle tissue.
In short, weight training can play a role in stimulating the nerves, prompting the nerves to pass more signals from the brain to the muscles, so that the muscles become more powerful. So, want to become more powerful, usually when the exercise may wish to increase some weight training.
