Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Aerobic capacity (VO2max). Timepoint: Measurements will be taken before the start of the intervention and after 8 weeks. Method of measurement: Aerobic capacity will be assessed using the 30–15 Intermittent Fitness Test (30–15IFT). In this test, the final running velocity achieved (VIFT) will be recorded, and maximal oxygen uptake (VO2max) will be estimated using a standard equation. All measurements will be performed before the intervention and after the 8-week intervention period. | — |
Secondary
| Measure | Time frame |
|---|---|
| Isokinetic strength performance of knee extensors and flexors. Timepoint: Measurements will be taken before the intervention and after 8 weeks. Method of measurement: The strength of the knee extensor and flexor muscles of the dominant leg will be assessed using an isokinetic dynamometer (Biodex System 4 Pro) in concentric mode at an angular velocity of 60°·s?¹. The indices of absolute and relative peak torque will be recorded, and measurements will be performed before the intervention and after 8 weeks. | — |
