Study summary

The long-term purpose of an on-going participatory action research program "The KLUB-study" in Sweden, that involves scientists and representatives from all levels of athletics, is to develop a sustainable framework for safe athletics (track and field) training for child athletes born 2002-2006. The first part of the research program, a 1-year longitudinal study analysing training and injury data, was completed in November 2017. The present study sets out to evaluate a website that aims to support coaches and caregivers in their role as adult key stakeholders to foster young athletes to become adult athletes who possess the tools to maintain a healthy sporting lifestyle.

Read the detailed description

The intervention will be implemented in youth athletics and evaluated in a randomised controlled trial (RCT). It will follow the consensus guidelines for studies in athletics and be reported according to the CONSORT checklist. The participating clubs will be randomly allocated into active and control group. The active group will be provided the intervention program, i.e. access to a website, aimed to support coaches, caregivers´ and athletes' and improve knowledge and health literacy to make more informed choices that promote health. The control group will continue to train according to their routines and will get access to the website after 4 months.

The participants will be assessed at three times, at the beginning of the study (T1), after four months (T2), at ten months (T3) and additional prospective data on training and injury will be collected during the first four months (T1b).

Interventions

  • OtherActive group

    For this study, the Frisk.Friidrott (Healthy.Athletics/Track\&Field) website has been developed. The purpose of the website is to provide an easy-to-use tool that can assist coaches and parents involved in youth athletics with information how to structure training and recovery planning, provide guidance on possible injuries, and provide other information on health for youth athletes.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2018 to primary completion in Jul 2018, 4 months.

Of 119 non-industry interventional studies with no phase under Athletic Injuries, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 14. This study's 4 months is below that.

Counting every sponsor, half of 121 studies reached it within 5 months; a quarter within 2 and three quarters within 14.

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 Oct 1, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
