Which action is essential when teaching backfloat to beginners?

When teaching backfloat to beginners, supporting their head and encouraging relaxation is essential because it helps to build their confidence in the water. Many beginners may feel anxious or unsure about floating on their back, as this position can be intimidating if they are not accustomed to it. By providing head support, the instructor ensures that the beginner feels secure and is less likely to panic. This support aids in maintaining proper body alignment and helps the beginner focus on relaxing their body, which is crucial for floating successfully.

Encouraging relaxation further allows beginners to experience buoyancy without tension, making it easier for them to find their balance in the water. Instructors can create a supportive environment that fosters learning, making the backfloat an achievable skill for students. This approach sets a positive foundation for later swimming skills, enhancing their overall comfort in the water.
