Study summary

The goal of this observational study is to determine if physical activity and the adherence to a Mediterranean diet have a relationship with body composition, growth, and maturation status in youth triathletes. The main question it aims to answer is:

  • Is body composition (fat and muscle) determined primarily by growth and biological maturation or by physical activity and the Mediterranean diet in youth triathletes? Participants already have been evaluated in body composition, mediterranean diet adherence and practical of physical activity during 3 years.
Read the detailed description

Triathlon is an individual, multidisciplinary and resistance sport with three stages: swimming, cycling and running, linked by two transitions. The importance of knowing body composition, eating patterns, level of physical activity and maturational state, will allow influence on training, increasing sports performance.

Regarding body composition and its relationship with performance, it has been observed that the greater the body fat, the lower the physical performance of triathletes. In each sport, athletes have different composition somatotypes. For triathlon, it is difficult to establish a specific somatotype, since it is a modality that encompasses three sports, among which the anthropometric characteristics of the athletes who practice them are not similar. In addition, since it is a relatively new category, there are not enough bibliographical references regarding anthropometry and body composition.

During biological maturation, there is an increase in the basal metabolic rate, so an optimal diet helps the growth process and improves the performance and recovery of athletes. Therefore, in the early stages of childhood and adolescence, adherence to the diet plays an important role in the acquisition of healthy lifestyles to determine an optimal state of health. The Mediterranean Diet model is associated with healthy eating habits, high levels of quality of life and physical benefits.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Acceptation of by parents

Exclusion criteria

Exclusion Criteria:

  • No attendance to body composition evaluation
  • Reporting less than 80% of assistance to physical activity sessions reported by trainer
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Ran from Nov 2021 to primary completion in Nov 2021, 0 months.

Of 100 non-industry observational studies under Feeding Behavior, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 62. This study's 0 months is below that.

Counting every sponsor, half of 101 studies reached it within 24 months; a quarter within 8 and three quarters within 62.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 5, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
