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 Results may not be published yet.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.

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.

Summary

This study compares a 'weekend warrior' exercise schedule—two days of combined resistance and jogging—to regular weekly exercise and usual lifestyle in sedentary female university students. Over eight weeks, researchers measure changes in aerobic capacity, muscle strength, body composition, sleep quality, and mood. The goal is to see if a condensed weekend workout can offer similar fitness benefits to spreading exercise throughout the week.

What this could mean

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

Active substance
Weekend Warrior Exercise (resistance training and jogging on two consecutive days per week)
What this could lead to
If effective, this could show that a weekend-only exercise schedule is a practical way for busy people to improve aerobic capacity and muscle strength.
What could go wrong
This is a small, short-term trial in healthy young women, so results may not apply to other groups. The exercise program may not be as effective as regular weekly exercise.

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: * Female university students aged 18 to 25 years. * Self-reported sedentary time of at least 6 hours per day, further assessed using the International Physical Activity Questionnaire (IPAQ). * No cardiovascular, pulmonary, neurological, metabolic, or musculoskeletal diseases. * Relatively regular menstrual cycles. * Able to understand the study procedures, willing to complete the intervention and assessments, and willing to provide written informed consent. Exclusion Criteria: * Any condition identified through clinical assessment or health screening that makes participation in moderate-intensity exercise or exercise-to-exhaustion testing inappropriate. * Participation in regular exercise training, a systematic weight-loss or body-shaping program, or another exercise intervention study within the previous 3 months. * Recent substantial body-weight fluctuations that may affect body-composition assessment. * Cardiovascular, pulmonary, neurological, metabolic, or musculoskeletal diseases, or current use of medications that may affect exercise performance, heart-rate responses, or muscle function. * Irregular menstrual cycles. * Inability to complete the 8-week intervention, post-intervention assessments, or required study records.
