Skeletal muscle is pivotal not only for movement but also for systemic metabolic regulation. Its physiology encompasses intricate networks of contractile machinery, mitochondrial dynamics, and ...

The sarcoplasmic reticulum (SR) is a specialised organelle in skeletal muscle fibres that plays a pivotal role in regulating calcium dynamics crucial for muscle contraction and relaxation. Acting as ...

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 ...

Interrupting prolonged sitting with periodic activity 'snacks' may help maintain muscle mass and quality, according to a new study. Interrupting prolonged sitting with periodic activity "snacks" may ...

The Bround Lab studies mitochondrial biology with an emphasis on heart and skeletal muscle physiology and disease. Mitochondria are important organelles which serve as the powerhouse and molecular ...

A study in the Journal of Applied Physiology suggests quick bursts of moderate-intensity exercise can help your body use amino acids from your meals, which helps you build muscle. Researchers found ...

Icing muscles after strenuous exercise is not just ineffective, it could be counterproductive, a new study in mice suggests. Credit...Melody Melamed for The New York Times Supported by By Gretchen ...
