you muscles are made of many individual muscle fibers. When you lift a weight or exert a force over and over again you damage these fibers (more specifically actin and myosin). When your body repairs the damage, you get more muscle mass!
your muscles burn when you exert yourself because when you lift heavy or lift for an excess ammount of reps you get a build up of lactic acid in your muscles
When you stretch an elastic band, your muscles exert a pulling force on the band. The force is generated by the contraction of your muscles, which results in the stretching of the band.
Muscle cells are the tissues that shorten and exert force. This is achieved through the sliding of actin and myosin filaments within the muscle fibers, causing them to contract and generate tension. This contraction allows muscles to exert force to produce movement or maintain posture.
Muscle strength refers to the ability of muscles to exert an external force. It is typically measured by the maximum amount of force a muscle or group of muscles can generate in a single effort.
Endurance strength refers to the ability of muscles to exert force repeatedly or sustain force over an extended period of time. It is closely related to muscular endurance, which is the ability of a muscle or group of muscles to perform repeated contractions over a prolonged period without fatigue.
The ability of muscles to exert a force one time.
