When you take a muscle through the full range of motion, it goes through three phases of muscle contraction: eccentric, isometric, and concentric. Placing more attention on one phase can yield ...

When you supplement with creatine or eat creatine-rich foods, it doesn’t stay in your body indefinitely. How long it lasts in ...

How does nitrate affect muscle contraction? Based on the mouse experiments, the researchers suggest that it has to do with the muscle fiber's response to calcium, which is an important signalling ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study.

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly ...

Normally, people's muscles do a lot of work that they're hardly aware of--lifting their bodies and maintaining posture against gravity. In space, that constant muscular work is removed.

After all, hypertrophy (the technical term for muscle growth) is largely a numbers game, and getting the equation right can equal maximum gains in minimal time. You want to work hard, but your goal ...
