Squatting position

(Redirected from Squatter's palsy)
For other uses, see Squat (disambiguation).
"Haunch" redirects here. For a part of an arch, see Haunch (arch).

Squatting is a versatile posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves supporting the weight of the body on the ischial tuberosities of the pelvis, with the lower buttocks in contact with the ground or a horizontal object. The angle between the legs when squatting can vary from zero to widely splayed out, flexibility permitting. Another variable may be the degree of forward tilt of the upper body from the hips. Squatting may be either full or partial.

Crouching is usually considered to be synonymous with squatting. It is common to squat with one leg and kneel with the other leg.[1] One or both heels may be up when squatting. Young children often instinctively squat. Among Chinese,[2] Southeast Asian and Eastern European adults, squatting often takes the place of sitting or standing.

Etymology

edit

Squatting comes from the Old French esquatir/escatir, meaning to "compress/press down".[3] The weight-lifting sense of squatting is from 1954.[3]

Resting position

edit

Full squatting involves resting one's weight on the feet with the buttocks resting on the backs of the calves. It may be used as a posture for resting or working at ground level particularly where the ground is too dirty or wet to sit or kneel.[1]

Most Western adults cannot place their heels flat on the ground when squatting because of shortened Achilles tendons which may be caused by habits:[4][5][6][failed verification]

  • sitting on chairs or seats
  • wearing shoes with heels (especially high heels)

For this reason the squatting position is usually not sustainable for them for more than a few minutes as heels-up squatting is a less stable position than heels-down squatting.[7] See also dorsiflexion.

Desmond Morris distinguished seven variant forms of squat as: Squat-kneel; Flat-footed Squat (the Asian squat,[8] or Slav squat); Tiptoe Squat (the Western squat,[9] or heels-raised squat[10]); Squat-sit; Legs-fold; Lotus position; and Legs Side-curl.[11][relevant?]

Equivalents to the Slav squat (see Gopnik) in Western culture, sometimes with the hands together in a prayer position, are the rap squat, prison pose, and jail pose. They are often used as photographic poses.[12][13][14]

Exercise

edit

Strength training

Main article: Squat (exercise)

In strength training, the squat is a full body exercise that trains primarily the muscles of the thighs, hips and buttocks, 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.

The pistols squat is a one legged squat common in crossfit exercises in which the non-working leg is kept horizontal.

The burpee is a full body exercise used in strength training and as an aerobic exercise that involves a squat. The basic movement is performed in four steps and known as a "four-count burpee".

Mālāsana or upavesasana in yoga

Upaveśāsana (literally "sitting down pose"), also known as Mālāsana meaning "garland pose", or simply the yoga squat, is an asana.[15]

The āsana is a squat with heels flat on the floor and hip-width apart (or slightly wider if necessary), toes pointing out on a diagonal. The torso is brought forward between the thighs, elbows are braced against the inside of the knees, and the hands press together in front of the chest in Añjali Mudrā.[16]

Tai Chi

edit

In Taoist Tai Chi, the "Dan Yu" (spine stretching) exercise involves squatting. It is intended to work primarily the pelvic region, the legs and the lower back. Fifty or more repetitions may be performed in advanced classes. The feet are placed in a stance wider than the shoulders. When squatting the knees move in the direction of the feet.[17][18][19]

Urinating and defecating

edit
 
 
 
 
Wolves and foxes urinate in a squatting position.[20][21][22]

The squatting defecation posture involves squatting by standing with the knees and hips sharply bent and the bare buttocks suspended near the ground. Squat toilets are designed to facilitate this posture and are common in various parts of the world.

When not urinating into a toilet, squatting is the easiest way for a female to direct the urine stream. If done this way, the urine will go forward. Some women use one or both hands to focus the direction of the urine stream, which is more easily achieved while in the squatting position.[23][failed verification]

A partial squatting position (or "hovering") while urinating is often done to avoid sitting on a potentially contaminated toilet seat, but it may leave urine behind in the bladder[24] and it is not good for the pelvic floor muscles.[25]

Canids often urinate in a squatting position, but usually raise their legs while scent marking.[20]

Health

This European woman's heel lifts off the ground when she is squatting. While Caucasians tend to flex the forefoot when kneeling or squatting, East Asians are more likely to keep the foot flat on the ground.[10]

In East Asian cultures such as Chinese, Japanese, Korean and Vietnamese, postures with high flexion including kneeling and squatting are used more often in daily activities, while in North America, people kneel or squat less frequently in daily activities, unless for occupational, religious, or leisure practices. The favored style of those high flexion postures also differs among ethnic groups. While Caucasians tend to flex the forefoot when kneeling or squatting, East Asians are more likely to keep the foot flat on the ground.[10][26]

In the two common styles of kneeling, the plantarflexed kneel and the dorsiflexed kneel, the lead leg may experience higher adduction and flexion moment, which is associated with increased knee joint loads.[27]

Risk of osteoarthritis

edit

There is increased incidence of knee osteoarthritis among squatters who squat for hours a day for many years. There is increased incidence of knee osteoarthritis among squatters who squat for hours a day for many years.[28] There is evidence that sustained squatting may cause bilateral peroneal nerve palsy.[29] A common name for this affliction is squatter's palsy although there may be reasons other than squatting for this to occur.[30][31][29] For societies who rarely squat, squatting as a different posture may bring health benefits.[32]

In patients with tetralogy of Fallot

edit

Toddlers and older children with the congenital heart disease tetralogy of Fallot will often instinctively squat during a "tet spell" (an episode involving a sudden development of blue skin, caused by a drop of oxygen in the blood), allowing more blood to flow to the lungs.[33] Squatting increases systemic vascular resistance and allows for a temporary reversal of the shunt. It increases pressure on the left side of the heart, decreasing the right to left shunt thus decreasing the amount of deoxygenated blood entering the systemic circulation.[34][35]

Squatting facets

edit

The existence of squatting facets on the distal tibia and talar articular surfaces of skeletons, which result from contact between the two bones during hyperdorsiflexion, have been used as markers to indicate if that person habitually squatted.[36][37]

Childbirth position

edit
Main article: Childbirth positions

Various people have promoted the adoption of these alternative birthing positions, particularly squatting, for Western countries, such as Grantly Dick-Read, Janet Balaskas, Moysés Paciornik and Hugo Sabatino. The adoption of these alternative positions is also promoted by the natural childbirth movement.

The squatting position gives a greater increase of pressure in the pelvic cavity with minimal muscular effort. The birth canal will open 20 to 30% more in a squat than in any other position. It is recommended for the second stage of childbirth.[38]

In ancient Egypt, women delivered babies while squatting on a pair of bricks, known as birth bricks.[39]

Sexual position

edit
Main article: Woman on top

There are versions of the "cowgirl" sex position where a woman is squatting over a man, who is lying on his back, instead of kneeling over him. These are referred to by different names such as Asian cowgirl, frog squat position, and froggystyle.[40] The woman can face forwards[41] or backwards (reverse).[42]
