What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

• Standardized Warm-UpOther

  2 minutes jogging and 4x30m side run; dynamic stretching for main locomotive lower limb muscles (2x10 hip adduction, 2x10 hip abduction, 2x10 butt kicks, 2x10 knee raises and 2x10 straight leg march), dynamic strength exercises (2x10 deep squats, and 2x10 forward lunges); incremental intermittent sprints and agility runs as follow: 2x10m pace, 2x20m pace, 2x30m pace, 1x30m with 10 decelerations (both feet), 1x30m with 10 decelerations (one foot), 2x30m with 4 changes of direction pace (90˚), 1x20m full pace and 1x30m full pace. The total time ofthe WU will be approximately 15 minutes.

• Elastic Band ExercisesOther

  Squats (10 reps), Hip Flexion (10 reps, each leg), Hip Extension (10 reps, each leg), Hip Abduction (10 reps, each leg), Hip Flexion with Knee Flexion (10 reps, each leg), Cross Walks (10 reps, forth and back) (All exercises are with elastic bands looped around the lower limbs)

What is being measured

The primary outcome is the main question the study is designed to answer.

1. Vertical jump

   Jump height and power will be evaluated using force plates (ForceDecks, Vald). The players will perform the countermovement jump, where they will begin from an upright position; a rapid downward movement to a knee angle of ∼90°, immediately transitioning to propel themselves upwards into the air.

   Measured: The evaluations will be conducted at baseline (before the warm-up), immediately after the warm-up intervention, and 10 minutes post-intervention.

2. Sprint Speed

   Sprint performance will be measured over 10 m and 20 m using photocell timing gates (Microgate). Players will begin from a standardized starting position, with the front foot placed 50 cm behind the first timing gate. Upon their own cue, athletes will accelerate maximally through the course, ensuring consistent running mechanics while crossing both the 10-m and 20-m gates at full speed for accurate measurement of short-distance sprint times.

   Measured: The evaluations will be conducted at baseline (before the warm-up), immediately after the warm-up intervention, and 10 minutes post-intervention.
