Which of the following measures can help prevent overexertion during a dive?

Maintaining a steady pace is essential in preventing overexertion during a dive. Diving can be physically demanding, and sudden bursts of speed or effort can lead to fatigue and increase the risk of accidents or emergencies. By pacing oneself, divers can manage their energy expenditure effectively, allowing for a more controlled and sustainable dive experience. This approach ensures that divers can enjoy their underwater exploration without pushing their physical limits, reducing the likelihood of exhaustion and promoting safety.

In contrast, descending rapidly can lead to increased physical strain, potentially causing stress on the body and affecting buoyancy control. Performing frequent equipment checks, while important for safety, can lead to unnecessary exertion if done excessively or incorrectly during the dive. Using a heavy weight belt can also contribute to fatigue, making it more challenging for a diver to maintain buoyancy and stability, which ultimately can lead to overexertion. Thus, maintaining a steady pace emerges as the most effective measure for preventing overexertion during a dive.
