context_page_description: The uneven bars or asymmetric bars is an artistic gymnastics apparatus. It is made of a steel frame. The bars are made of fiberglass with wood coating, or less commonly wood. The English abbreviation for the event in gymnastics scoring is UB or AB, and the apparatus and event are often referred to simply as "bars". The bars are placed at different heights and widths, allowing the gymnast to transition from bar to bar. A gymnast usually adds white chalk to the hands so that they can grip the bar better.
context_section_description: Gymnasts are permitted to tape their hands or use grips or hand guards on bars level 4 through elite. Their coaches are also permitted to apply chalk and/or water to the bars to ensure gymnasts don't slip off.
  Unlike high bar and rings in MAG, gymnasts may not be lifted to the uneven bars to begin their routines. They may mount the apparatus with either a simple or a difficult skill, on either the high or low bar; running mounts and springboards are permitted.
  Once the routine has started, the coach may not physically interfere with the athlete in any way, however he or she is permitted to stand on the mat during release moves and dismounts. If the gymnast falls on one of these skills, her coach is allowed to catch her or break her fall; the coach is also allowed to lift her back to the high bar to continue her routine. If a springboard has been used for the mount, the coach is supposed to quickly step in and remove it so that it does not interfere with the routine.
  If a gymnast falls from the apparatus, she has 30 seconds to re-mount. Within this time limit, she is allowed to readjust her grips or chalk her hands again, if necessary. However, if she does not return to the bars within 30 seconds, her routine will be finished. Many judges are flexible with this rule, especially if the gymnast took a hard fall and needs a minute to shake it off and re-gain her focus. Often the judge or judging assistant will give the gymnast a ten-second warning.
