No Evidence of Short-Term Changes in Postural Balance and Muscle Strength With Application of the Floss Band

Introduction:The Floss Band is a tool that has been growing in the sports world in order to improve various parameters to improve performance.Objective: to investigate the effects of the Floss Band technique applied around the ankle associated with resisted heel raising exercises on postural balance and maximum isometric strength of the plantar flexors.Methods: 22 volunteers, men and women, randomly divided into two groups: Floss Band group (GF) and Sham group (GS).Everyone performed pre-and post-intervention tests, namely static postural balance through the displacement of the center of pressure (CoP) measured by a Wii Balance Platform, and maximum voluntary isometric contraction (MVIC) using a load cell.In the GF, the Floss Band was applied around the tibiotarsal joint with a pressure of 160 mmHg and in the GS group, the Floss Band was placed in the same region, but with 0 mmHg pressure.Participants in both groups performed a plantar flexion exercise in CCF, with 3 sets of 12 repetitions.At the end of the interventions, the tests were repeated.Results: In the CoP displacement variable, only GS improved, while in the MVIC variable there was no improvement in both groups.Conclusion: it was concluded that as an acute effect, the Floss Band does not generate an improvement in static postural balance and MVIC, while the GS demonstrated an improvement in balance, attributed to Post-Activation Potentiation (PPA).
