The hole size in the middle of the disc must not exceed how many millimeters?

In powerlifting, the specifications for the equipment used, including the size of the discs, are crucial for ensuring fair competition and safety. The correct answer states that the hole size in the middle of the disc must not exceed 53 millimeters. This standard is established to accommodate the barbell’s diameter, which ensures that the discs fit securely on the bar without wobbling or shifting during lifts.

Using the correct hole size is essential not only for maintaining stability during the lift but also for uniformity across all equipment used in competitions sanctioned by the International Powerlifting Federation (IPF). Adhering to this standard helps uphold the integrity of the sport, as any deviation could lead to discrepancies in performance and measurement during competitions.

In competitions, ensuring that all equipment meets IPF regulations is vital for fairness among athletes, and having the disc hole size properly specified is part of maintaining that standard.
