Strong Support

Even though your nerves fire faster after training, they still respond to how hard you’re trying at the same rate—your brain’s control system didn’t get more sensitive.

The increase in muscle force after 4 weeks of strength training is mediated by adaptations in motor unit recruitment and rate coding

Randomized Controlled Trial
Human
2019 Apr

After four weeks of strength training, the participants’ muscles fired more signals, but the way those signals matched how hard they were trying to push stayed the same — like turning up the volume without changing the music’s rhythm.

After four weeks of strong, held ankle lifts, your nerve signals to the muscle get faster during moderate efforts, making your muscle stronger without needing more muscle mass.

After training, your tendons get a bit looser, so your muscles can start working sooner when you try to push, making you feel stronger faster.

When young men do isometric leg exercises for 12 weeks, their thigh muscles get bigger—and that bigger muscle size helps explain about 1 in 5 of their strength gains, even if their nerves aren’t getting better at telling muscles to work harder.
