What is the strongest muscle in human body? By strength: The quadriceps. By size to power ratio: The masseter (jaw). In ordinary parlance, muscular strength usually refers to the ability to exert a force on an external object—for example, lifting a weight. By this definition, the masseter or jaw muscle is the strongest. If strength refers to the force exerted by the muscle itself, e.g., on the place where it inserts into a bone, then the strongest muscles are those with the largest cross-sectional area. By this definition, the strongest muscle of the body is usually said to be the quadriceps femoris or the gluteus maximus. http://en.wikipedia.org/wiki/Muscle Post last edited by Terry on Sep 17 2016.

What does exercise do for muscle performance? How fast the muscle can develop its maximum strength is the power of muscle contraction. The power of muscle depends on strength and speed; the equation for that is: power = (force x distance)/time. The body can have extreme power from muscles (7,000 kg-m/min) for a short period of about 10 seconds. Then power gradually reduces by 75 percent within 30 minutes.

Muscle Power and Fitness Training to improve power can include lifting weights, throwing implements such as medicine balls, running against a resistance, and plyometrics (depth jumping and bounding). Muscle Power is one of the main fitness components, important for success in many sports. Certain sports, such as weightlifting, boxing and weight throwing, it is one of the most important physical attributes. In many other sports, including football, good power is also very important as part of the overall fitness profile.

What's the strongest muscle in the human body? Masseter. The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars. Muscles of the Uterus.The uterus sits in the lower pelvic region.here are three types of muscles in the human body: cardiac, smooth and skeletal. Cardiac muscle makes up the wall of the heart and is responsible for the forceful contraction of the heart. Smooth muscles make up the walls of the intestine, the uterus, blood vessels, and internal muscles of the eye.

- How skeletal muscles adapt to a repeated stimulus depends, to a large extent, on the inherent characteristics of the muscles themselves. Specifically, the types of fibers that make up individual muscles greatly influence the way your athletes will adapt to their training programs.hese fibers are also capable of producing more power than ST fibers. Like the FT-A fibers, FT-B fibers have a large motor neuron and fiber diameter, but a low mitochondrial and capillary density and myoglobin content. They also are high in creatine phosphate and glycogen, but low in triglycerides.

Define Strength, Power & Muscular Endurance Muscular strength is the ability of a muscle or muscle group to exert force to overcome the most resistance in one effort. Strength can be measured based on the amount of weight lifted. Upper-body and lower-body strength are measured separately.

The underappreciated role of muscle in health and disease Although it is debatable whether it is muscle strength or simply muscle mass that is important in determining bone strength and mass, it is significant that skeletal muscle mass was correlated positively with bone mineral content and bone mineral density in MINOS (Mediterranean Intensive Oxidant Study), a prospective study of osteoporosis and its determinants in men .

lever The muscles of the body produce the forces that move the levers. The basic components of a lever are the fulcrum, the force arm, and the weight arm. A first-class lever, such as the joint between the base of the skull and the first cervical vertebra, has a fulcrum between the weight and the applied force. The body contains few second-class levers, which have the weight between the fulcrum and the force.

House Passes 56th Anti-Obamacare Measure House Passes 56th Anti-Obamacare Measure. WASHINGTON -- The House of Representatives on Tuesday voted for the 56th time to repeal or undermine the Affordable Care Act. The vote was largely symbolic, because the measure is unlikely to pass the Senate and would face a certain veto from President Barack Obama if it did.

How to Improve Your Power-to-Weight Ratio The more power an athlete has per pound, the higher the power-to-weight ratio. Generally, athletes measure their power-to-weight ratio by pounds per watt. They take the amount they weigh and divide it by the amount of power they can produce, measured in watts.

- Force-velocity Relationship. The force generated by a muscle is a function of its velocity. Historically, the force-velocity relationship has been used to define the dynamic properties of the cross-bridges which cycle during muscle contraction. The force-velocity relationship, like the length-tension relationship, is a curve that actually represents the results of many experiments plotted on the same graph. Experimentally, a muscle is allowed to shorten against a constant load.

Sarcomere Two of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament. Myosin has a long, fibrous tail and a globular head, which binds to actin. The myosin head also binds to ATP, which is the source of energy for muscle movement.Myosin can only bind to actin when the binding sites on actin are exposed by calcium ions. Actin molecules are bound to the Z line, which forms the borders of the sarcomere. Other bands appear when the sarcomere is relaxed.A muscle fiber from a biceps muscle may contain 100,000 sarcomeres. The myofibrils of smooth muscle cells are not arranged into sarcomeres.wo of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament.

- Power factor Also given on the nameplate as P.F. or PF, power factor is the ratio of the active power (W) tothe apparent power (VA) expressed as a percentage. It is numerically equal to the cosine of theangle of lag of the input current with respect to its voltage, multiplied by 100.he nameplate provides the power factor for the motorat full load.Active power is the power that does work; apparent power has a reactive component. Thisreactive component is undesirable-the utility company must supply it, but it does no work.

What is the effect of hormones on muscles? Muscles are mostly genetically programmed, but they are also influenced by hormones such as testosterone, which makes muscles grow. Because women do not have high testosterone levels, they do not bulk up the way men do when they lift weights.Other hormones influence muscle mass, too.uscles are mostly genetically programmed, but they are also influenced by hormones such as testosterone, which makes muscles grow.
