🤸Rules & Play

Since 2006 every routine receives two scores that are added together. The difficulty score, or D-score, has no upper limit and is calculated from the values of the counting elements plus credit for required element groups and for connections performed without a pause. The execution score, or E-score, starts at 10.00 and only falls, with judges deducting 0.1 for a small fault, 0.3 for a medium one, 0.5 for a large one and 1.00 for a fall. The perfect 10 was abolished after the 2004 Athens Games, where a start-value error decided the men's all-around and a crowd protest over Alexei Nemov's high bar score halted competition. The old system could no longer separate gymnasts whose difficulty had outgrown its ceiling.

The two programs developed separately and were standardised at different times. The men's six apparatus — floor, pommel horse, rings, vault, parallel bars and high bar — descend directly from the nineteenth-century German Turnen movement and were essentially fixed by the 1930s, with a strong emphasis on upper-body strength. The women's program entered the Olympics in 1928 and was built around vault, uneven bars, balance beam and floor, emphasising acrobatic tumbling, flexibility and, on beam and floor, an explicit artistry component judged within the execution score. The result is that men contest eight Olympic medal events and women six, an imbalance FIG has been repeatedly asked to address. The apparatus themselves have not changed in principle for roughly a century.

Simone Biles has the strongest case by almost every measure. Through Paris 2024 she holds 41 Olympic and World Championship medals with 30 golds, including a record 23 world titles and six world all-around crowns, plus Olympic all-around golds in 2016 and 2024. Five elements in the Code of Points carry her name, and FIG has deliberately valued her hardest skills below what she argued they were worth in order to discourage imitation. The historical alternatives are serious: Larisa Latynina's 18 Olympic medals remain the gymnastics record, Kohei Uchimura went unbeaten in all-around competition from 2009 to 2016 on six apparatus, and Vitaly Scherbo won six golds at a single Games. The answer usually depends on whether you value accumulation, dominance or difficulty of the task.

Women must turn 16 during the calendar year of the competition and men must turn 18. The women's minimum was raised from 15 to 16 in 1997, after decades in which teenagers as young as 14 won Olympic titles — Nadia Comaneci was 14 when she won the 1976 all-around, a record now permanently unbreakable. The rule was introduced partly on health grounds, since very young gymnasts training elite volumes face growth-plate injuries and disordered eating risks, and partly because minors cannot meaningfully advocate for themselves inside coaching systems. Age falsification has been alleged repeatedly, most publicly against members of the Chinese team at Beijing 2008, and FIG now requires documentary verification through national federations.

The Code of Points catalogues every recognised element, and a gymnast who invents a genuinely new one can have it entered under their own name permanently. The requirements are strict: the element must be submitted to the FIG technical committee in advance, and it must be performed successfully in qualification at a World Championships or Olympic Games, without a fall or a major error. Natalia Yurchenko's round-off vault entry, Yelena Produnova's front handspring double front, Aliya Mustafina's bar transition and Epke Zonderland's release combinations all carry their inventors' names. Simone Biles has five named elements across vault, beam and floor, the most of any woman, including the Yurchenko double pike named Biles II in 2023.

The twisties are a sudden loss of air awareness in which a gymnast cannot sense where their body is during rotation. Twisting skills are performed almost entirely on proprioceptive memory built through thousands of repetitions, and when that mapping breaks down the athlete may over-rotate, under-rotate or freeze mid-air. This is not stage fright: landing a double somersault without knowing which way is down is a realistic route to a spinal or head injury, which is why gymnasts stop competing rather than push through. Simone Biles withdrew from the Tokyo Olympic team final in July 2021 for exactly this reason. The episode changed how the sport treats the condition, which is now managed as an injury requiring graded rehabilitation rather than as a lapse of nerve.
