OPTIMIZING SPEED ENDURANCE DEVELOPMENT IN YOUNG TRIATHLETES UNDER THE AGE 15–16

Abstract

This research aimed to develop and experimentally validate a specialized training methodology for enhancing speed endurance in young triathletes aged 15–16. Speed endurance is a critical physical quality in triathlon, determining the athlete’s ability to sustain high-intensity efforts across swimming, cycling, and running segments. The research employed an eight-week pedagogical experiment involving two groups—control (traditional training) and experimental (specialized methodology)—each consisting of ten athletes. The experimental program integrated circuit training, interval work, plyometrics, and technical-tactical exercises, with progressively reduced rest intervals to induce pronounced fatigue. Pre- and post-test assessments included 400 m swim time, 20 km cycling time, 3 km and 5 km run times, stroke/step frequency, and overall endurance scores. Results indicated that the experimental group showed significantly greater improvements in speed endurance indicators compared to the control group, with notable gains in swimming, cycling, and running performance, as well as enhanced muscular endurance and movement efficiency. The findings confirm that a structured, fatigue-based circuit training approach effectively develops speed endurance and specialized physical preparedness in young triathletes. The study provides practical recommendations for coaches to optimize training programs during this sensitive developmental period.
