Document Summary
Length of muscle matters, innervation matters towards force production. Velocity at which a muscle contracts matters towards force. 2-2. 25 micrometers is where muscle has the most force. Muscle fibers can be between 10 micrometers to 30 cm long. Think about it like a rope or onion. If you place a little bit of load on a muscle, it substantially changes and it is not proportional. Relationship between stress and strain becomes disproportionate to the point of failure. Muscles react in a totally different way than any other material. Power of a muscle at fmax at different v. Fmax isometric like trying to lift a bolted down chair, there is load and force exerted but the chair is not actually lifting. Getting faster, produce force but not the same force as isometric, steep curve as velocity gets bigger (moving faster, less weight) We can create isometric force if the muscle is lengthening. Tendons to connect muscle to bone.
