Definition & Meaning of "survival backstroke"in English

What is the "survival backstroke"?

The survival backstroke is a swimming technique used for long-distance swimming in open water or survival situations. It is similar to the regular backstroke but is performed at a slower, more relaxed pace to conserve energy. The swimmer uses a gentle flutter kick while keeping the arms moving in a smooth, alternating motion. The swimmer's face stays above the water, allowing for easy breathing. This stroke is designed to help a swimmer stay afloat and move steadily without tiring quickly, making it ideal for situations where endurance and energy conservation are important.
