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
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 This study
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 Results may not be published yet.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

Summary

This study compared supramaximal interval running (SIR) and small-sided games (SSG) in 40 elite male football players over six weeks of preseason training. Both methods improved fitness, but SIR led to greater gains in aerobic capacity, body composition, and anaerobic markers. The results can help coaches tailor training programs for better performance.

What this could mean

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

Active substance
Exercise training (supramaximal interval running and small-sided games)
What this could lead to
If this shows one method is clearly better, coaches could design more effective preseason training for elite football players.
What could go wrong
This is a small, completed study in healthy male athletes, so results may not apply to other groups or real-game conditions.
