What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Repeated sprint
Time Frame: 6 weeks
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
6 weeks
Time to exhaustion test
Time Frame: 6 weeks
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
6 weeks
6-minute submaximal run test:
Time Frame: 6 weeks
A 6-minute submaximal run test on a typical 400-meter outdoor track at a steady speed was used to estimate running economy.
6 weeks
Cooper vo2 max Test
Time Frame: 6 weeks
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
