NCT04367532

Brief Summary

The hypothesis is that self-myofascial release (SMR) intervention on the cuff muscles would affect positively sprint performance and jump height, as well as, decrease Achilles tendon stiffness. The second hypothesis is that tissue flossing would be more effective than foam rolling. The participants will be randomly assigned to foam rolling, tissue flossing, and control group (without any intervention). After the intervention, repeated measures will be performed (15m sprint, countermovement jump (CMJ) and Achilles tendon stiffness). This will aim to improve sprint time, jump height and decrease tendon stiffness.

Outcome Measures

Primary Outcomes (3)

  • Change in counter-movement jump (CMJ)

    A maximum vertical jump with counter-movement.

    Baseline, 5 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes

  • Change in 15-meter sprint run

    The 15-meter sprint involves a participant starting behind a timing gate and running through a second timing gate 15 meters away.

    Baseline, 5 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes

  • Change in viscoelastic properties of the Achilles tendon.

    Stiffness measured on (1) Achilles tendon origin, (2) Achilles tendon on the center ankle joint, and (3) intermuscular septum between medial and lateral head of the gastrocnemius muscle.

    Baseline, 5 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes

Study Arms (3)

Foam rolling

EXPERIMENTAL

Foam rolling of cuff muscles.

Other: Foam rolling

Tissue flossing

EXPERIMENTAL

Tissue flossing of cuff muscles.

Other: Tissue flossing

Control group

NO INTERVENTION

Without any intervention.

Interventions

Foam rollingOTHER

Foam rolling performed on cuff muscles in 3 sets of 30 seconds per each muscle part in duration with a 15-second rest between sets. The first sets on the central part of the cuff muscles, the second on the medial and third on the lateral side of the cuff.

Foam rolling
Tissue flossingOTHER

A standard cuff muscle bandaging technique on cuff muscle. After the application, each participant is asked to perform a 2 min ankle-exercise program.

Tissue flossing
