Kneeling is a type of position in which one or both knees are in direct contact with the ground. Though similar to squatting in that both positions bring the individual closer to the ground by bending the legs, kneeling uses the knees to support the body whereas the knees do not provide this level of support, nor do they come into contact with the ground while squatting. There are a variety of reasons that might cause someone to kneel, such as kneeling to rest, as an expression of reverence or submission, during sexual intercourse, and even during childbirth. Many other animals can kneel as well, such as horses, elephants, and other four-legged mammals.
Knee pain is usually caused by inflammation or an injury. The most common cause for knee pain while kneeling is Knee Bursitis, when repeated pressure on a bursa (the small fluid filled sacs that reduce friction between bones and soft tissue) can cause it to swell and become inflamed. Other causes may be Knee Arthritis, Patellar Tendonitis, and Osgood Schlatters.
Since August 2016 American athletes have protested against police brutality and racism by kneeling on one knee during the U.S National Anthem. Since 2017, many players have taken a knee to protest against President Donald Trump’s policies. The protests started in the NFL after San Francisco 49ers quarterback, Colin Kaepernick, sat and knelt during the anthem before his preseason games in 2016.
A kneeling chair is an ergonomically designed chair with the thighs dropped to 60 or70 degrees from vertical (as opposed to 90 degrees in a standard chair); some of the bodyweight is supported by the shins. The chair reduces back pain by dividing the weight between the shins and the glutes. Other benefits are improving posture, developing core muscle, and increasing comfort and concentration.
