Brief Summary

Purpose of the Study This study looked at how two popular warm-up techniques-tissue flossing and foam rolling-affect muscle flexibility, muscle properties, and jumping ability in young male handball players. The goal was to see which method might be better for preparing athletes for performance. What Are These Techniques? Tissue flossing: Wrapping a special elastic band tightly around a muscle or joint for a short time while moving. This temporarily reduces blood flow, and when the band is removed, blood rushes back in, which may boost muscle readiness. Foam rolling: Using your body weight to roll muscles over a firm foam cylinder. This applies pressure to the muscle and fascia, helping to relax tight areas and increase flexibility. Who Took Part? 30 male handball players, around 17 years old, who were healthy and injury-free. None had regularly used tissue flossing or foam rolling before. How Was the Study Done? Each player tried all three conditions on separate days: Tissue flossing Foam rolling Control (no special technique, just exercises) Before and after each session, the researchers measured: Active range of motion (AROM) - how far they could move their leg muscles without help Muscle properties - stiffness and tone of key thigh muscles Jump performance - height and speed of force production in a countermovement jump Measurements were taken before, 2 minutes after, and 15 minutes after each warm-up.

Outcome Measures

Primary Outcomes (1)

• Active Range of Motion

  Measured using the Active Knee Extension (AKE) test for both legs to assess hamstring flexibility.

  Before the intervention, 2 minutes after, and 15 minutes after the intervention.

Secondary Outcomes (2)

• Jump Performance - Jump Height

  Before the intervention, 2 minutes after, and 15 minutes after the intervention.

• Jump Performance - Braking Rate of Force Development

  Before the intervention, 2 minutes after, and 15 minutes after the intervention.

Other Outcomes (2)

• Viscoelastic Muscle Properties - Stiffness

  Before the intervention, 2 minutes after, and 15 minutes after the intervention.

• Viscoelastic Muscle Properties - Tone

  Before the intervention, 2 minutes after, and 15 minutes after the intervention

Tissue Flossing conditioning

EXPERIMENTAL

Tissue flossing using a 5 cm x 3.5 m green Sanctband Comprefloss band was wrapped around the thigh area. After the floss band was applied, the participants did 10 bodyweight squats, making sure to bend their knees to a 90-degree angle. Next, they did 10 dynamic lunges on each leg, switching legs after each lunge. After finishing these exercises, the floss band was removed.

Other: Tissue Flossing conditioning

Foam rolling conditioning

EXPERIMENTAL

Each participant rolled the quadriceps on the right, then the left, for 30 seconds each, and did the same for the hamstrings, starting with the right and then the left, also for 30 seconds each side.

Other: Foam Rolling

No intervention

NO INTERVENTION

Participants perform standard dynamic warm-up exercises (bodyweight squats and lunges) with no additional device or treatment.

Interventions

Foam Rolling OTHER

Using a firm foam roller to roll the quadriceps and hamstrings for 30 seconds per side.
