Skeletal muscles are by far the largest organ of the human body, accounting for up to 40%–50% of the body weight. In the past much of our knowledge on muscle contraction and relaxation was obtained from experiments with isolated frog muscle or single muscle fibers stimulated with electric pu...

The mind-muscle connection refers to the conscious effort to focus one’s attention on the contraction of a specific muscle or muscle group during exercise. This practice involves mentally engaging with the working muscle, aiming to isolate and enhance its activation without relying solely on the ...

In the late 19th century the principle ofconservation of energywas derived in part from observations that fermentation and muscle contraction are essentially problems in energetics. Biological energetics began with studies that established the basic equation of respiration as:Fuel + oxygen → carbon dioxi...
