Enhancing endurance capacity in youth swimming

Abstract

This study examines the development of aerobic endurance in young swimmers aged 16-17 years through an 8-week training programme incorporating strength and speed-strength endurance exercises. Sixteen qualified male athletes with 6-8 years of training experience participated in the investigation. Aerobic endurance was assessed using three indicators – endurance index, speed reserve, and endurance coefficient – measured over a 25 m reference segment and a 400 m freestyle distance.
