Can lifters use supportive gear such as belts or knee sleeves?

Supportive gear, such as belts and knee sleeves, is permitted in competitions governed by the International Powerlifting Federation (IPF) as long as it adheres to the specifications outlined in the IPF rules. These specifications dictate the materials, construction, and dimensions of the gear to ensure fairness and safety among competitors. This means lifters can enhance their performance and safety during lifts with the appropriate gear, provided it meets the defined criteria.

The option that states that supportive gear requires approval from referees is not accurate, as lifters do not need individual approval for their properly specified equipment; they simply need to ensure it conforms to regulatory standards. The suggestion that supportive gear is completely banned contradicts the IPF's regulations, which actively allow for the use of certain supportive equipment. Lastly, the idea that such gear is permissible only during warm-up is misleading, as lifters can use it throughout the competition phase, again as long as the gear complies with IPF specifications.

Thus, the correct answer underscores the importance of adhering to the IPF's defined standards for supportive gear, which is essential for maintaining a standardized and fair competition environment.
