How does physical fitness impact a lifeguard's emergency response?

Physical fitness significantly enhances a lifeguard's ability to respond effectively during emergencies, which is why the correct choice highlights the increase in their chances of success in rescues. A well-conditioned lifeguard possesses greater strength, endurance, and agility, allowing them to perform rescues more efficiently. They can swim faster, navigate through challenging conditions with ease, and sustain the physical demands of potential rescues, especially those involving struggling swimmers or rough water.

Improved physical fitness also contributes to mental alertness and quicker reaction times, essential attributes when seconds count during an emergency situation. A lifeguard who is physically fit is generally more confident in their abilities, which can further enhance their performance when responding to a crisis. This holistic improvement in both physical and mental readiness underscores the importance of fitness for lifeguards in ensuring safety and effective emergency responses.
