What techniques can improve students' endurance while swimming?

Implementing interval training is an effective technique for improving students' endurance while swimming because it involves alternating periods of high-intensity exercise with periods of lower intensity or rest. This approach can help build both aerobic capacity and muscular endurance, as it challenges the body to adapt to varying levels of exertion. When students consistently perform interval training, they can enhance their stamina and overall swimming performance, allowing them to swim longer distances and with greater efficiency over time.

While other techniques listed may offer benefits in specific areas—like buoyancy aids helping with flotation, fins providing propulsion, or diving exercises targeting skills and speed—interval training focuses directly on building endurance. This method can be tailored to fit different levels of swimming proficiency and can be easily adjusted based on individual progress, making it a versatile approach for instructors looking to enhance their students' swimming endurance effectively.
