One of the main things that will inhibit muscle contraction is the build up of lactic acid during aerobic exercise. Lactic acid will inhibit the bodys ability to break ATP down into ADP and therefore restrict the amount of useable energy available to the muscle.
The mechanism for muscle contraction involves the creation of cross-bridges (binding) between myosin and actin filaments. Skeletal muscle contraction is prevented by tropomyosin, a protein which covers the binding sites on the actin filament - preventing myosin from binding.
This tropomyosin moves out of the way when calcium binds to troponin.
Muscle inhibition by Golgi spindle apparatus located inside the musculotendin.
Muscle fatigue is the main factor that inhibits muscle contraction. Muscles need oxygen and energy to contract and muscle fatigue is the lack of oxygen in a muscle. The build up of lactic acid is a factor of muscle fatigue.
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
Load placed on the muscle
Isometric contraction
constant contraction of a muscle is called the muscle tone
The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
Factors are, skeletal muscle contraction, breathing movements and vasoconstriction of veins.[venoconstriction].
Skeletal Muscle contraction, breathing movements, and vasoconstriction.
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
Muscle contraction is affected by four factors:1. The number of muscle fibers stimulated 2. The relative size of the fibers 3. Frequency of stimulation 4. The degree of muscle strength
