what is the difference between a strong muscle contraction and weak muscle contraction?

The difference between a strong muscle contraction and a weak muscle contraction is the muscle fibers that contract.

Muscle weakness can be due to pain inhibition (from musculoskeletal conditions like arthritis). In contrast to the weakness accompanying pain, the weakness seen with neuromuscular disorders is more profound and often more progressive.

Muscular strength is the amount of force you can put out or the amount of weight you can lift. Muscular endurance is how many times you can move that weight without getting exhausted (very tired).

When a muscle contracts, the actin is pulled along myosin toward the center of the sarcomere until the actin and myosin filaments are completely overlapped. In other words, for a muscle cell to contract, the sarcomere must shorten. However, thick and thin filaments—the components of sarcomeres—do not shorten.

Another difference between MET and PNF is that the contraction during MET is performed at the initial barrier of tissue resistance, rather than at the end of the range of motion (ROM) of a joint [6].

Braxton Hicks contractions usually are milder than those of real labor are, and they do not occur at regular intervals. True labor contractions occur at regular intervals and are stronger than Braxton Hicks contractions.

What's the relationship between cardiac muscle stretch and force of contraction? What effect does this have on stroke volume? The more cardiac muscle stretches, the more forcefully it contracts. These stronger contractions increase stroke volume.

The distinction between a weak verb and a strong verb is based on how the past tense of the verb is formed. Weak verbs (more commonly called regular verbs) form the past tense by adding -ed, -d, or -t to the base form—or present tense—of the verb, such as call, called and walk, walked.

Although smooth muscle contraction relies on the presence of Ca++ ions, smooth muscle fibers have a much smaller diameter than skeletal muscle cells. T-tubules are not required to reach the interior of the cell and therefore not necessary to transmit an action potential deep into the fiber.

The difference between Frail and Weak. When used as adjectives, frail means easily broken physically, whereas weak means lacking in force (usually strength) or ability.

Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion.

It can also be a way to build strength. Muscle flexing is more accurately known as muscle contraction, because when you flex your muscles, you're creating tension that's temporarily making the muscle fibers smaller or contracted. ... So, instead of moving weights, the muscle is being strengthened by holding still.

In muscle cells, thick filaments made up of myosin and thin filaments made up of actin compose structures called sarcomeres, which are the basic units of muscle contraction.

Muscle Types: Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.

Mg ions have been reported to interfere with muscle contraction in live tissue, but in glycerinated tissues, the addition of KCl and MgCl2 solutions to ATP increases the strength of muscle contraction because of myosin's high affinity for these ions.

Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.

Muscle strength is the ability to exert a maximal amount of force for a short period of time. ... Muscle endurance is the ability to do something over and over for an extended period of time without getting tired. In the gym, that may be doing 50 body weight squats in a row, moving to a rhythm.
