The speed at which humans can swim varies depending on factors such as swimming technique, physical fitness, and the distance being swum. Elite competitive swimmers can achieve impressive speeds, while recreational swimmers typically swim at slower speeds. Here are some general guidelines:
Freestyle (Front Crawl): This is the fastest and most commonly used swimming stroke for speed. Elite swimmers can reach speeds of around 5-6 meters per second (18-21 kilometers per hour or 11-13 miles per hour) over short distances. Average recreational swimmers typically swim at speeds ranging from 1.5-2.5 meters per second (5-9 kilometers per hour or 3-6 miles per hour).
Backstroke: The backstroke is generally slightly slower than freestyle. Elite swimmers can swim at speeds similar to freestyle, while recreational swimmers may swim at slightly slower speeds.
Breaststroke: Breaststroke is typically slower than freestyle and backstroke. Elite swimmers can swim at speeds around 2-3 meters per second (7-11 kilometers per hour or 4-7 miles per hour), while recreational swimmers often swim at slower speeds.
Butterfly: Butterfly is generally the slowest of the four competitive swimming strokes. Elite swimmers can achieve speeds similar to or slightly faster than breaststroke, while recreational swimmers may swim at slower speeds.
It's important to note that the speeds mentioned above are general ranges and can vary significantly depending on individual factors. Additionally, swimming speeds can be affected by other variables such as the distance swum, fatigue, water conditions, and the swimmer's age and experience.
Overall, achieving faster swimming speeds often requires a combination of proper technique, strength, endurance, and training.
