13 participants will be in continuous aerobic conditioning training group, who will only perform aerobic exercise. running along with increase duration.
| Study group | Role | What they receive |
|---|---|---|
| Group A | Experimental | 13 participants will be in sprint interval training group, they will only perform repeated sprints exercise and will not perform continuous aerobic conditioning exercise. Receives: Other: sprint interval training |
| Group B | Experimental | 13 participants will be in continuous aerobic conditioning training group, they will only perform running exercise and will not perform repeated sprint exercise. Receives: Other: Continuous aerobic conditioning |
What is being measured
The primary outcome is the main question the study is designed to answer.
Repeated sprint
The Repeated Sprint Test consists of a sequence of maximal sprints (usually 6 to 10 sprints) over a distance of 20 to 40 meters, separated by 20 to 30 seconds of either passive or active recovery
Measured: 6 weeks
Time to exhaustion test
A Time to Exhaustion (TTE) test measures fatigue by determining how long an individual can sustain a specific workload (e.g., power output or speed) before becoming unable to continue
Measured: 6 weeks
6-minute submaximal run test:
A 6-minute submaximal run test on a typical 400-meter outdoor track at a steady speed was used to estimate running economy.
Measured: 6 weeks
Cooper vo2 max Test
The Cooper Test is a 12-minute run test used to measure a person's aerobic endurance and estimate their cardiovascular fitness, specifically their VO₂ max
Measured: 6 weeks

What does the primary outcome measure?
Repeated sprint (time frame: 6 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07726836, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
