The Athens Games staged three gymnastics disciplines across two venues. Artistic gymnastics and trampoline filled the Olympic Indoor Hall, the largest arena of the Athens complex, between August 14 and 23. Rhythmic gymnastics took place a few kilometers away at the Galatsi Olympic Hall from August 26 to 29. In all, 252 gymnasts from 45 nations came to compete. The format tightened the rules of team and individual qualification: for the first time a six-member team could send only three gymnasts to each apparatus, with all three scores counting, and each country was held to two gymnasts in the all-around and apparatus finals - changes meant to spread the medals more widely among nations.

The first crisis came in the men's all-around. South Korea's Yang Tae-young performed his parallel-bars routine, but the judges misidentified one of its elements and set his start value at 9.9 instead of 10.0 - a tenth of a point that, in a sport decided by hundredths, mattered enormously. The Korean Olympic Committee appealed to the Court of Arbitration for Sport. The court found the error real but dismissed the case anyway: the protest had come after competition ended, too late under the rules, and there was no evidence of corruption or bad faith strong enough to overturn a result settled on the field of play. The principle held, but the unease lingered.

Then came the high-bar final. Nemov, the great Russian who had ruled the apparatus four years earlier in Sydney, unleashed a routine of six release moves, four of them strung together in a breathtaking sequence - three Tkatchev variations and a Gienger. But he took a large step on his landing, a clear two-tenths deduction, and the judges scored him 9.725, dropping him to third with competitors still to come. The crowd erupted. For some fifteen minutes the booing made it impossible to proceed. Swayed by the uproar, the judges revisited the routine and nudged the score to 9.762 - but it changed nothing, and Nemov, the night's hero, finished without a medal.

What happened in that hall did not stay there. The Athens controversies exposed the breaking point of the old ten-point scoring system, where a perfect score capped how much difficulty could ever be rewarded. In 2006 the sport overhauled its entire scoring framework, separating the difficulty of a routine from its execution and removing the ceiling that had penalized the most ambitious gymnasts. The change is credited with pushing athletes toward greater acrobatic risk and harder skills, especially on the high bar - the very apparatus where a defiant Athens crowd had refused to stay quiet. The medals were settled that summer; the argument reshaped the future.
