Swimming provides cardiovascular benefits and high calorie expenditure

Swimming is recognized as a highly effective sport for improving endurance, building musculature, and enhancing cardiovascular fitness while minimizing impact on joints. Due to the buoyancy of water, it is particularly beneficial for individuals with back or joint issues, obesity, or asthma.

Caloric expenditure varies significantly by stroke and intensity. An 80 kg person may burn approximately 344 kcal per hour with slow breaststroke, 768 kcal with brisk breaststroke, and up to 900 kcal per hour with fast crawl strokes. To support weight reduction, organizations such as the European College of Sport Science (ECSS) and the American College of Sports Medicine (ACSM) recommend approximately 250 minutes of moderate weekly training.

For sustainable performance gains, experts suggest structured training cycles and precise monitoring of heart rate zones. Rather than relying on general formulas like '220 minus age,' individual field tests or sports medical diagnostics are preferred to determine maximum heart rate and manage training intensity across different physiological zones.
