Here, weâre concerned, like Lord Chesterfield, with âthe average cat.â On average, female cats live one to two years longer than male cats. On average, indoor cats live longer than outdoor cats. On average, wild, homeless, and feral cats live dramatically shorter lives than domestic cats.
During contraction, myosin heads bind to actin molecules of the. thin filaments. Flexing of the myosin heads pulls the thin filaments over the thick. filaments - shortening the sarcomere. Muscle contraction requires.
Flexibility is a derivative of strength. Muscle tightness is secondary to muscle weakness. Wherever you see a limitation in motion is an indicator that one or more of the muscles that cross that axis cannot contract efficiently. When a muscle, or group of muscles, cannot contract efficiently it means that they cannot effectively shorten. When a muscle or group of muscles cannot effectively shorten, then the muscles on the opposite side of the axis cannot fully lengthen. This inefficiency in muscle contraction is expressed as muscle tightness.
