Foam Rolling and Tissue Flossing of the Cuff Muscles

Study Overview
=================
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.

Detailed Description
-----------------
Foam rolling provides beneficial results in ankle range of motion, muscle flexibility or muscle sourness. Tissue flossing is popular in athletic training and physical therapy, as an effective strategy for ankle range of motion or performance. However, there is a lack of knowledge about the use of foam rolling and tissue flossing during a 60 minutes post-intervention examination on the performance and soft tissue stiffness. The main aim of this study is to investigate the effect of foam rolling and tissue flossing of the cuff on sprint performance, jump height and Achilles tendon stiffness at different time points. The second aim is to assess the effectiveness of those self-myofascial release methods (SMR). This study will include healthy, recreational active subjects aged between 20 and 25 years old.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Foam rolling<br>Foam rolling of cuff muscles. | Other: Foam rolling<br>* 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 |
