Lifting heavy weights may help you enhance your muscle strength more than light weight training because the nervous system facilitates improvements in strength during high-load training, researchers suggests. The study aimed to find out how the brain and motor neurons cells that send electrical signals to muscle adapt to high versus low-load weight training. The findings showed that despite similar increases in muscle thickness, high-load training may be superior for enhancing muscle strength than low-load training.
The nervous system activates more of the motor neurons or excites them more frequently when subjected to high-load training. This increased excitation could account for the greater strength gains despite comparable growth in muscle mass, the researchers said. If you're trying to increase strength whether you're a gym rat or an athlete training with high loads is going to result in greater strength adaptations.
Although, low-load training remains a viable option for those looking to simply build mass or avoid putting extreme stress on joints, still, when it comes to building strength especially amid a busy schedule heavier is better.High-load training is more efficient" and "it's more time-efficient. We're seeing greater strength adaptations. And now we're seeing greater neural adaptations.
