Which is a potential consequence of overexertion while diving?

Overexertion while diving can lead to increased oxygen consumption due to the body's heightened physical demand for energy. As a diver exerts themselves more than is ideal, such as by swimming too fast or struggling against currents, the muscles require more oxygen to function effectively. This increased demand can lead to rapid exhaustion and may compromise the diver's ability to safely manage the dive, as physiological stress responses kick in.

Normally, divers need to maintain a controlled pace to use their air supply efficiently. When oxygen consumption rises, it may also lead to potential risks such as a quicker ascent to the surface to attempt to breathe, which can result in additional hazards like decompression sickness. Understanding the relationship between physical exertion and oxygen consumption is essential for divers to ensure their safety and enjoyment of the sport.
