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 ...

Research in exercise physiology has significantly advanced our understanding of muscle fatigue – the exercise‐induced decline in the ability of a muscle to generate force. This phenomenon encompasses ...

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 ...

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 ...

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 ...
