What else can I help you with?
Does the triceps contract concentrically during the down phase of a push up?
No, the triceps do not contract concentrically during the down phase of a push-up. Instead, they are involved in an eccentric contraction as the elbows flex and the body lowers toward the ground. This eccentric action helps control the descent and stabilize the movement. During the upward phase, the triceps contract concentrically to extend the elbows.
What muscle contract during inhalation and what muscles contract during exhalation?
The intercostal muscles, (muscles between the ribs), contract.
Is a press up concentric eccentric or isometric?
A press-up (or push-up) involves both concentric and eccentric muscle contractions. During the upward phase (pushing away from the ground), the muscles in the chest, shoulders, and triceps contract concentrically. Conversely, during the downward phase (lowering the body), these muscles lengthen and contract eccentrically as they control the descent. There is no isometric phase involved in a standard press-up unless you hold a position at a specific point in the movement.
When performing push ups the concentric phase is?
when you push yourself away from the floor, the lowering phase is the eccentric phase concentric = shortening of muscles - i like to think of this as when the muscles are "working" eccentric = lengthening of muscles - i like to think of this as when the opposite muscles would work to perform the action - e.g. when biceps brachii is eccentric in a bicep curl it is on the lowering phase (i.e. elbow extension - usually performed by triceps brachii)
What happens in the wall of the uterus to push the baby out.?
The muscles contract which in turn push the baby out.
Can individual muscles pull in only one direction?
all of them, muscles can only contract and relax
Why does my stomach hurt when I do push-ups?
When you do push-ups, the pressure on your abdominal muscles can cause them to contract and tighten, which may lead to discomfort or pain in your stomach. This is a normal response as your muscles are working hard to support your body during the exercise.
How air exhaled?
The muscles in your diaphragm contract to push the air out of your lungs.
How muscled move bones?
Muscles contract and relax to pull/push
Do muscle push and pull?
No. Muscles only pull (contract) and relax.
Based on this activity do skeletal muscles pull or push to allow movement?
not push only pull or contract
What muscles are worked during dumbbell push-ups?
During dumbbell push-ups, the muscles primarily worked are the chest muscles (pectoralis major), triceps, and shoulder muscles (deltoids).
