F57 (classification)
Events open to people in this class include the shot put, discus and javelin.
International Paralympic Committee defined this classification on their website in July 2016, "Athletes who meet one or more of the MDC for impaired muscle power, limb deficiency, impaired passive range of movement and leg length difference, who do not fit any of the previously described profiles, fall into this class.
"[1] The Spectator Guide for the Rio Paralympics defines the class as, "wheelchair athletes (effects of polio, spinal cord injuries and amputations)"[2] People competing in the seated position in this class have mobility limitations that cannot exceed 70 points.
[5] Because of the potential for balance issues related to having an amputation, during weight training, amputees are encouraged to use a spotter when lifting more than 15 pounds (6.8 kg).
[4][5][6] The nature of a person's amputations in this class can effect their physiology and sports performance.
[5][7][8] Lower limb amputations effect a person's energy cost for being mobile.
To keep their oxygen consumption rate similar to people without lower limb amputations, they need to walk slower.
[8] People in this class use around 120% more oxygen to walk or run the same distance as someone without a lower limb amputation.
[5][8] Because of the potential for balance issues related to having an amputation, during weight training, amputees are encouraged to use a spotter when lifting more than 15 pounds (6.8 kg).
[5] Lower limb amputations effect a person's energy cost for being mobile.
To keep their oxygen consumption rate similar to people without lower limb amputations, they need to walk slower.
Common problems with intact upper limbs for people in this class include rotator cuffs tearing, shoulder impingement, epicondylitis and peripheral nerve entrapment.
[4][11] In general, Les Autres classes cover sportspeople with locomotor disabilities regardless of their diagnosis.
This is a standing class for people with weakness in one leg muscle or who have joint restrictions.
[4] There was a large range of sportspeople with different disabilities in this class at the 1984 Summer Paralympics.
[4][20] Sportspeople in this class use wheelchairs on a regular basis as a result of reduced muscle function.
[20] Medically, this class includes people with hemiparesis, and hip and knee stiffness with deformation in one arm.
[21] For the 1984 Summer Paralympics, LAF3 was defined by the Games organizers as, "Wheelchair bound with normal arm function and good sitting balance.
"[22] People with spinal cord injuries compete in this class, including F7 sportspeople.
[27] People with lesions at the L4 to S2 who are complete paraplegics may have motor function issues in their gluts and hamstrings.
[28] Disabled Sports USA defined the functional definition of this class in 2003 as, "Have very good sitting balance and movements in the backwards and forwards plane.
"[23] Field events open to this class have included shot put, discus and javelin.
[29] The shot put used by women in this class weighs less than the traditional one at 3 kilograms (6.6 lb).
Rests can be used on the frame but they need to be present only for safety reasons and to aide in athlete stability.
For other events, organizers generally have the option to use that formula to give all throwers six consecutive throws.
This policy was put into place in 2014, with the goal of avoiding last minute changes in classes that would negatively impact athlete training preparations.
All competitors needed to be internationally classified with their classification status confirmed prior to the Games, with exceptions to this policy being dealt with on a case-by-case basis.
[35] Sometimes the health examination may not be done on site because the nature of the amputation could cause not physically visible alterations to the body.
[7][39] The classification system takes several things into account when putting people into this class.
[40][41] Sportspeople competing in this class include Mexico's Angeles Ortiz Hernandez, Ireland's Orla Barry and Algeria's Nassima Saifi.
