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 This study
Registered, but not yet taking participants.
By invitation only
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two exercise programs in college students: high-intensity functional training (HIFT) and moderate-intensity continuous training (MICT). The goal is to see which approach better improves body composition, physical fitness, and blood vessel health compared to no exercise. Participants will be randomly assigned to one of three groups and will follow their program for eight weeks, with measurements taken before and after to track changes.

What this could mean

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

Active substance
High-Intensity Functional Training (HIFT) and Moderate-Intensity Continuous Training (MICT)
What this could lead to
If successful, this could help identify the most effective exercise type for improving cardiovascular health and fitness in young adults, potentially guiding future exercise recommendations.
What could go wrong
The trial is relatively small and short-term, and results may not apply to all populations. Exercise programs may also have varying adherence rates, affecting outcomes.

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 90 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Jun 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

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

18 to 35 years

Sex

Anyone

Healthy volunteers

Accepted

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

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

Inclusion Criteria: * Age 18 to 35 years. * Currently enrolled college or university student. * Able to provide written informed consent. * Able to attend baseline and post-intervention testing visits and participate in assigned intervention sessions. * Cleared for exercise participation based on the health screening form and investigator review. Exclusion Criteria: * Known cardiovascular, metabolic, pulmonary, renal, neurological, musculoskeletal, or endocrine disorder that would make exercise unsafe or confound outcome measures. * Current pregnancy or planning pregnancy during the study period. * Current smoking, vaping nicotine products, or use of tobacco products. * Uncontrolled hypertension or resting blood pressure values that make exercise testing unsafe based on investigator judgment. * Use of medications known to substantially affect cardiovascular function, vascular tone, or exercise responses, unless approved by the PI. * Any injury, orthopedic limitation, or medical condition preventing safe participation in HIFT, MICT, or physical fitness testing. * Currently participating in structured high-intensity interval, functional, or endurance training more than two days per week during the previous three months. * Do not speak English.
