Young runners showed different training adaptations over two seasons. While maximal oxygen uptake improved in the first year, running economy enhanced in the second year, despite similar training.
Area of Science:
- Sports Science
- Exercise Physiology
- Pediatric Sports Medicine
Background:
- Endurance training adaptations in adolescent athletes are crucial for performance.
- Understanding how training affects physiological markers over time is important for optimizing athletic development.
- Previous research often focuses on single training seasons, limiting insights into long-term adaptations.
Purpose of the Study:
- To evaluate changes in endurance performance markers in young track-and-field runners over two consecutive training seasons.
- To compare physiological adaptations between male and female adolescent athletes.
- To investigate the impact of consistent training volume and intensity on different performance indicators.
Main Methods:
- Nineteen male and sixteen female athletes (aged 15-17) specializing in middle and long-distance running participated.
- Key parameters measured included maximal oxygen uptake, running economy, and the second ventilatory threshold.
- Measurements were taken three times during each of the two training seasons, with training load analyzed prior to tests.
Main Results:
- In the first training season, significant improvements in relative maximal oxygen uptake were observed in both male and female athletes.
- During the second training season, running economy showed significant improvement in both genders, while maximal oxygen uptake remained unchanged.
- Training volume and intensity were comparable across both seasons and between male and female participants.
Conclusions:
- Consistent endurance training, even with similar volume and intensity, can yield different physiological adaptations in young runners across consecutive seasons.
- Adolescent athletes may experience distinct improvements in maximal oxygen uptake and running economy in different training years.
- This highlights the complex nature of training adaptations in developing athletes and suggests periodization may influence specific outcomes.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
