Effort nearer than load to fulcrum = mechanical disadvantage., movements of the thigh are accomplished by muscles anchored to the pelvic girdle Movement is achieved through antagonistic muscle pairs The claim that muscles only push and never pull is a common misconception
In reality, muscles work in pairs to create movement by both contracting (shortening) and relaxing (lengthening)
When a muscle contracts, it generates a pulling force on the bones it’s attached to, allowing for movement. The statement that muscles are only able to pull and they never push is true Muscles work by** contracting and exerting** a pulling force They are made up of a pair of opposing muscles, for example, the bicep and tricep in your arm
When one muscle (like the bicep) contracts, it's pulling the forearm up To straighten the arm, the bicep relaxes and the tricep contracts, pulling the forearm. Your muscles can only pull, so your upper arm muscles cannot simply push your lower arm away Instead, you need a different set of muscles to pull your arm in the other direction
Try flexing your arm a few times and see if you can find the muscle that straightens your arm
Try tensing your arm to hold it very straight. Muscles can only generate force by pulling They cannot push, relying on coordinated actions with bones and joints for movement. The muscles that pull things closer to your body are called pulling muscles and vice versa
When you do a bench press the muscles in your chest and arms are pulling on the front of your arms. Basis of judgment muscles function by contracting, which creates a pulling force They lack the structural mechanism to directly push
