Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Randomized controlled trial
Primary purpose: SCREENING

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.
