What is the joint action during the concentric phase of reverse fly?
horizontal abduction
During the concentric phase of the triceps bench dip is the shoulder joint experiencing flexion or extension?
Flexion
What is the joint action during the eccentric phase of a biceps curl?
A concentric movement would be flexing the elbow and curling a dumbbell towards the shoulder, an eccentric contraction would be the opposite movement ie bringing the dumbbell back down towards the thigh.
What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
What muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
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 muscles are eccentric and concentric when doing incline bench press?
The bench press has two phases: eccentric and concentric. The first phase, as you lower weight toward your chest, is called the eccentric, or muscle-lengthening motion. The second phase, as you raise the weight back up, is called the concentric, or muscle-shortening phase. It is during the concentric phase that you can feel your chest getting tight. Learning which muscles are used during the concentric phase of the bench press is beneficial for focusing your mind on the correct area and therefore improving your exercise technique.The primary concentric mover of the bench press is the pectoralis major, which you may better know as the chest. Depending on which version of the bench press you are doing, you will be recruiting a specific part of the muscle group. The regular bench press on a flat surface mainly works your middle pecs. The incline and decline versions mainly work your upper and lower pecs, respectively.
What phase is the muscle the strongest eccentric concentric or isometric?
Isometric
In concentric phase of squat what muscle arr contracting?
The quads
What is the muscle group that stabilises the knee joint during the stance phase?
Quadriceps femoris
Why do not action potentials occur during the repolarization phase?
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
What is postactive instruction in education?
The post active phase in education is the last phase of instruction. During post action, students are evaluated on how well they learned the material during the interactive phase.
