What is the consequence of failing to meet the depth requirement in a squat?

The depth requirement in a squat is pivotal in powerlifting, as it defines whether the lifter has performed the movement correctly according to the standards set by the International Powerlifting Federation. In powerlifting, a successful squat requires the lifter to lower their body until the tops of their thighs are at or below the horizontal level of their knees. This ensures that the lift meets the technical standards necessary for it to be valid.

When a lifter fails to achieve the required depth, the lift does not conform to the IPF rules. Hence, the consequence is that the lift will be deemed unsuccessful. This decision by the referee is not arbitrary; it stems from the imperative that all lifts must adhere to uniform standards to maintain fairness and integrity in the competition. Therefore, the correct answer reflects the fundamental rule that the performance must meet depth criteria to be recognized as a valid lift.
