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 ...

To understand what causes muscle fatigue, it’s worth looking at what exactly muscle fatigue is. If you exercise regularly, you may be familiar with the sensation of a dull ache in your muscles or ...

Instead, CICR acts as a dormant but dangerous silent risk factor, staying quiet under normal conditions yet becoming a major driver of pathology when RyR1 signaling is disrupted. This model resolves a ...

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 ...

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 ...

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 ...

The study of fish exercise physiology and muscle metabolism encompasses the examination of how mechanical activity and varying swimming intensities affect muscle growth, cellular structure, and ...

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 ...
