What is the benefit of interval training in swim instruction?

Interval training is an effective method in swim instruction designed to enhance physical performance, specifically by building both stamina and speed. This training approach involves alternating periods of intense swimming with shorter recovery periods. By pushing the swimmers to exert themselves during the intense intervals, they develop muscular endurance and improve cardiovascular efficiency. The recovery periods give them a chance to rest briefly, enabling them to maintain a higher overall training intensity over time.

The key to interval training lies in its structure; the swimmer is taught to swim at varying intensities, which not only helps improve their speed but also trains their body to recover efficiently, thereby building stamina. This system prepares swimmers for the demands of competitive swimming as it mimics the varying pace and effort levels they will face during swim meets. Thus, incorporating interval training into swim instruction can significantly enhance a swimmer's performance and overall swim skills.
