Companion studies suggest muscle begins to decline decades before sarcopenia takes hold for keeps. The best part: The process ...

Statins are a cornerstone of heart health, but muscle pain and weakness cause many patients to quit taking them. Scientists have now identified the precise molecular trigger behind these side effects.

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

Calcium is critical for bone health, optimal muscle activity, and other body processes such as blood clotting and heart function. How much calcium you need depends on your age and stage of life. Share ...

Calcium is an essential nutrient needed by all living creatures, including humans. Vitamin D is a prohormone that helps the body absorb calcium, which is essential for bone health. Bones and teeth ...

Making sure that your workout is working for you can be one of the most important parts of planning out your fitness journey, but what is muscle activation and how can you go about achieving it?

Skeletal muscle mechanics and force generation are governed by complex interactions between contractile proteins and passive structural elements. At the cellular level, the sarcomere – the fundamental ...
