Final answer:
In powerlifting competitions, if a lifter successfully lifts a mis-loaded bar that's heavier than intended, they are granted a successful lift at that weight.
Step-by-step explanation:
If a lifter's attempt is mis-loaded too heavy but the attempt is a successful lift, according to powerlifting competition rules, the lifter will be granted a successful lift at the mis-loaded weight. This situation falls under the purveyance of the sport's regulations, which seek to preserve fairness while acknowledging the lifter's effort and success under the unintended challenge. Notwithstanding, the lifter is typically not granted an immediate re-attempt, a no lift ruling, or a re-attempt at the end of the round unless the rules of the specific competition state otherwise. However, it's crucial for the lifter and the officials to verify the weight and communicate clearly to ensure the accuracy of the competition's proceedings.
