Brian Glancy, a senior investigator in the Muscle Energetics Laboratory, researches how mitochondrial and contractile networks are optimized within muscle cells to maintain energy balance.

Increasing muscle temperature through warm-ups enhances contractile function and power, but maximum force remains unchanged, ...

Though many people experience muscle twitching, it's often incorrectly identified as a muscle spasm. While both are involuntary contractions of a muscle, muscle spasms and muscle twitching aren't ...

A research group has uncovered important details about how platelet-activating factor (PAF)—a powerful molecule involved in inflammation and allergic reactions—triggers contractions in the smooth ...

A new study provides evidence that COVID-19 patients' heart damage is caused by the virus invading and replicating inside heart muscle cells, leading to cell death and interfering with heart muscle ...
