Which entry technique involves running and diving into the water?

The stride jump is the entry technique that involves running and diving into the water. This method is particularly effective in situations where a lifeguard needs to quickly enter the water to rescue someone or respond to an emergency. By running before diving, the lifeguard can maintain a forward momentum that helps them effectively penetrate the water and reach their target faster.

The stride jump allows the lifeguard to get into a streamlined position as they enter the water, which minimizes resistance and helps them to quickly submerge. It is useful in shallow water as well as situations where immediate access is needed without excessive splashing, making it ideal for quick responses.

The other techniques mentioned serve different purposes or are suitable for different conditions. For instance, the long shallow dive is typically employed in deeper water where a more controlled entry is needed, while a compact jump is used for smaller waves or places where the depth is uncertain. The back jump is generally used for entering the water in a controlled manner from a height, such as from a boat. Each technique has its own applications, but the stride jump specifically emphasizes the action of running followed by a dive.
