What is the precision of muscle produced by movement?
The precision of movement produced by a muscle is due
What is isometric?
what resistance isometric movement is common painful if strain of the wrist muscle present? what resistance isometric movement is common painful if strain of the wrist muscle present?
What happens to the muscle tissue in response to resistance training?
the muscle tissue breaks and then grows back stronger and thicker
Does muscle contraction always promote movement?
No, muscle contraction doesn't always promote movement. For example, in an isometric contraction, the muscle does not change length, so movement is not produced. Additionally, some muscles can contract to stabilize joints without producing visible movement.
Fermentation in muscle cells produces?
Fermentation in muscle cells produces lactic acid. This happens when you have overworked your muscles, which can happen during exercise.
What happens when the supply of energy rich molecules in the muscle is used up?
when a supply of energy-rich molecules in a muscle is used up latic acid is produced
What happens when the supply of energy-rich molecules in a muscle in used up?
when a supply of energy-rich molecules in a muscle is used up latic acid is produced
What are the differences between isotonic, isometric, and isokinetic exercises in terms of muscle contraction and movement?
Isotonic exercises involve muscle contractions with movement, like lifting weights. Isometric exercises involve muscle contractions without movement, like holding a plank. Isokinetic exercises involve muscle contractions at a constant speed, like using a machine that provides resistance throughout the full range of motion.
Explain the relationship between weight training and progressive resistance?
Weight training versus resistance trainingResistance training involves the application of elastic or hydraulic resistance to muscle contraction rather than gravity. Weight training provides the majority of the resistance at the beginning, initiation joint angle of the movement, when the muscle must overcome the inertia of the weight's mass. After this point the overall resistance alters depending on the angle of the joint. In comparison, hydraulic resistance provides a fixed amount of resistance throughout the range of motion, depending on the speed of the movement. Elastic resistance provides the greatest resistance at the end of the motion, when the elastic element is stretched to the greatest extent.
What are the load effort force and the fulcrum in a biceps muscle?
In the biceps muscle, the load is the weight or resistance being lifted, such as a dumbbell. The effort force is generated by the muscle itself to lift the load. The fulcrum is the point in the body where the muscle attaches and pivots to create movement.
Bodily movement produced by skeletal muscles is called?
Skeletal muscles are attached to the bones by tough cords called tendons. When nerve signals are sent from the brain and spinal cord, these muscles contract to produce movement.
What happens to muscle force production when the muscle is too short?
Force produced is reduced, when the muscle is over-stretched or under-stretched it is weaker. Most muscles will produce max force at roughly 90 degrees.
