What are the signs of an overexerted diver?

The signs of an overexerted diver include rapid breathing, fatigue, and difficulty keeping up with the diving group. When a diver is overexerted, their body requires more oxygen, which leads to an increase in breathing rate. This rapid breathing is a physiological response to the added stress and effort the body is experiencing. Additionally, fatigue is a common symptom as energy is consumed quickly during strenuous activity underwater. A diver may struggle to maintain pace with a group due to exhaustion, impacting their safety and enjoyment of the dive. Recognizing these signs is crucial, as they indicate that the diver may need to slow down, rest, or ascend to a shallower depth to recover.

The other options do not reflect signs of overexertion in diving. A calm demeanor and controlled movements are typically indicative of a well-adjusted and comfortable diver. Excessive buoyancy and slow ascent may be indicative of other issues, such as equipment problems or proper buoyancy control, rather than overexertion. Frequent adjustment of equipment can occur for various reasons during a dive, but it is not a direct sign of overexertion. Understanding these signs helps divers recognize when to take necessary precautions for their safety and well-being underwater.
