The complete statements and roper order of the muscle contraction while weightlifting is:
1.Frequency.
2.Isometric.
3.Concentrically.
4.Motor units.
The proper order of the sentences are:
3. No immediate movement of the bar is demonstrated despite the production of muscle force, which demonstrates Concentrically contraction.
1. When ready, he initiates neural recruitment of his ankle, knee, and hip extensors by increasing the frequency of action potentials to the lower-limb extensors.
4. Voluntarily exerting more effort, additional Motor units are recruited, which results in the production of greater forces, prior to joint movement.
2. Progressively increasing force production allows the force to exceed that of the bar's inertia. Extensors of the ankle, knee, and hip begin to contract Isometric.
Muscle contractions are available in two types eccentric and concentric. When a muscle contracts concentrically, it shortens and produces force that is larger than the weight being lifted. This permits you to lift the weight by exerting more force than the weight. You cannot lift the weight if the concentric muscle contraction does not provide adequate force. Your bicep contracts concentrically as you lift and draw a weight toward your shoulder, such as when you perform an arm curl.
