Summary
Young triathletes exhibit high maximal oxygen uptake (VO2max) comparable to elite single-sport athletes. Their ventilatory threshold on a treadmill was lower than typically seen in runners.
Area of Science:
- Sports Physiology
- Exercise Science
- Endurance Sports
Background:
- Triathlon is a multi-sport event requiring high levels of cardiovascular fitness.
- Understanding the physiological characteristics of athletes who specialize in triathlon from a young age is crucial for training and performance.
- Few studies have comprehensively assessed the physiological profiles of young triathletes who have no prior experience in single-sport disciplines.
Purpose of the Study:
- To determine the physiological profile of young male triathletes who commenced their athletic careers in triathlon.
- To compare cardiorespiratory fitness levels between cycle ergometer and treadmill testing in this cohort.
- To evaluate the cardiorespiratory fitness of elite young triathletes against established benchmarks for single-sport elite athletes.
Main Methods:
- Twenty-nine male competitive triathletes (regional, national, and international ranks) participated.
- Maximal oxygen uptake (VO2max) was measured using both a cycle ergometer (CE) and a treadmill (TM).
- Ventilatory threshold (Th(vent)) was assessed during both CE and TM protocols.
Main Results:
- No significant difference was observed between cycle ergometer VO2max and treadmill VO2max in the triathletes.
- Elite triathletes demonstrated VO2max values comparable to elite athletes in single-sport disciplines (swimming, cycling, running).
- While ventilatory threshold was similar across testing modalities, treadmill ventilatory threshold was lower in triathletes compared to normative data for runners.
Conclusions:
- Young triathletes possess a physiological profile, particularly VO2max, that is competitive with elite single-sport athletes.
- The findings suggest that triathlon training effectively develops cardiorespiratory fitness.
- The lower treadmill ventilatory threshold in triathletes warrants further investigation regarding sport-specific adaptations and testing protocols.
