Squat (exercise)

In strength training and fitness, the squat is a compound, full body exercise that trains primarily the muscles of the thighs, hips and buttocks, quadriceps (vastus lateralis, vastus medialis, vastus intermedius and rectus femoris), hamstrings, as well as strengthening the bones, ligaments and insertion of the tendons throughout the lower body. Squats are considered a vital exercise for increasing the strength and size of the legs and buttocks, as well as developing core strength. Isometrically, the lower back, the upper back, the abdominals, the trunk muscles, the costal muscles, and the shoulders and arms are all essential to the exercise and thus are trained when squatting with the proper form.

The squat is one of the three lifts in the strength sport of powerlifting, together with deadlifts and bench press.

Squat (Warhammer 40,000)

In the fictional universe of Warhammer 40,000, the Squats are a dwarf-like race descended from the humans that colonised high gravity worlds. Separated from the rest of humanity over the millennia, they evolved their own distinct morphology and culture. Squats were discontinued from the game in the 1990s by Games Workshop though their existence remains somewhat canon. Their omission from the game was explained by a Tyranid invasion of their Home Worlds wiping them out almost to a man. The survivors were then assimilated into the Imperium, however there are rumours that the squats created Tau technology which despite being younger than the Imperium, is more advanced.

Biology

Squats evolved from the human miners and explorers sent to reap the mineral wealth at the center of the galaxy. The high gravity environment, combined with the punishing mining conditions eventually changed their morphology. The subsequent generations became gradually shorter and stockier. The Squat Home Worlds were isolated from the rest of humanity during the Age of Isolation. When they were reunited with the rest of the Imperium, wars were launched against them in the belief that they were aliens. Eventually, the Squats were accepted, along with other abhumans, as being human in nature. They are now considered a separate race, though they are fundamentally human.

Squat effect

The squat effect is the hydrodynamic phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure that causes the ship to be closer to the seabed than would otherwise be expected. This phenomenon is caused when water that should normally flow under the hull encounters resistance due to the close proximity of the hull to the seabed. This causes the water to move faster, creating a low-pressure area with lowered water level surface (See Bernoulli's principle). This squat effect results from a combination of (vertical) sinkage and a change of trim that may cause the vessel to dip towards the stern or towards the bow.

Squat effect is approximately proportional to the square of the speed of the ship. Thus, by reducing speed by half, the squat effect is reduced by a factor of four. Squat effect is usually felt more when the depth/draft ratio is less than four or when sailing close to a bank. It can lead to unexpected groundings and handling difficulties.

Physical exercise

Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and merely enjoyment. Frequent and regular physical exercise boosts the immune system and helps prevent the "diseases of affluence" such as heart disease, cardiovascular disease, Type 2 diabetes, and obesity. It may also help prevent stress and depression, help to promote or maintain positive self-esteem, improve mental health generally, and can augment an individual's sex appeal or body image, which has been found to be linked with higher levels of self-esteem.Childhood obesity is a growing global concern, and physical exercise may help decrease some of the effects of childhood and adult obesity. Some care providers call exercise the "miracle" or "wonder" drug—alluding to the wide variety of benefits that it can provide for many individuals.

Exercise (options)

The owner of an option contract has the right to exercise it, and thus require that the financial transaction specified by the contract is to be carried out immediately between the two parties, whereupon the option contract is terminated. When exercising a call option, the owner of the option purchases the underlying shares (or commodities, fixed interest securities, etc.) at the strike price from the option seller, while for a put option, the owner of the option sells the underlying to the option buyer, again at the strike price.

Styles

The option style, as specified in the contract, determines when, how, and under what circumstances, the option holder may exercise it. It is at the discretion of the owner whether (and in some circumstances when) to exercise it.
