What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study asks how exercise intensity affects body temperature regulation in children and youth (ages 9-16) compared to young adults (ages 20-25). Participants will exercise at light, moderate, and vigorous intensities in a hot room (36°C) while researchers measure heat loss and body temperature. The goal is to understand if children's bodies handle heat differently during exercise, which could inform safer physical activity guidelines.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Exercise at different intensities (light, moderate, vigorous) in a hot environment
What this could lead to
Could improve guidelines for safe exercise in hot weather for children and youth, helping prevent heat-related illness.
What could go wrong
This is a small, early-stage study (12 participants) that measures physiological responses, not health outcomes. Results may not apply to all children or real-world conditions.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 12 people

The number the study aims to enrol. It can still change while the study runs.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

9 to 25 years

Sex

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Healthy male or female. * Aged 9-16 years or 20-25 years. * Habitually active, defined as participating in regular physical activity at least 3 times per week for at least 20 minutes per session over the previous 6 months. * Able to understand and communicate in English or French. * For participants younger than 18 years, written parental or guardian consent and participant assent are required. Exclusion Criteria: * Acute illness at the time of testing (e.g., cold, flu, or infection). * History of a chronic medical condition that may affect thermoregulation, cardiovascular function, or exercise capacity (e.g., cardiovascular disease, metabolic disorders, respiratory disease including asthma requiring regular medication, or neurological disorders). * Use of medications known to affect thermoregulation, hydration status, or cardiovascular responses. * History of heat-related illness (e.g., heat exhaustion or heat stroke). * Digestive abnormalities or gastrointestinal conditions that may contraindicate ingestion of a telemetry pill. * Any condition that, in the opinion of the investigators, would compromise participant safety or the integrity of the data.
