stroke efficiency

Stroke efficiency refers to how effectively the energy generated by a swimmer's arm movement translates into forward motion. It measures how well a swimmer converts the power of each stroke into distance traveled with minimal wasted effort or drag. High stroke efficiency means the swimmer moves smoothly and quickly with less energy expenditure, resulting in better performance and endurance. Factors influencing stroke efficiency include technique, timing, body position, and strength. Improving stroke efficiency allows swimmers to swim faster and longer with less fatigue, making it a key aspect of effective and sustainable swimming.
