Discussion

The aim of this study was to investigate the acute effects of wrapping floss band around the upper-thigh, while using different degrees of wrapping pressure, on ASLR, MVC, and TMG contractile characteristics of the knee extensors and flexors.
The findings of the present study show a statistically significant improvement in knee extensors MVC up to 30 minutes after the intervention (resulting in small to medium benefit) and a significant shortening in RF TMG contraction time (Tc_RF) immediately after the intervention (small benefit), where the LOW wrapping pressure condition was applied. In addition, medium benefits were associated with the LOW condition compared to HIGH for extMVC and Tc_RF, and medium benefits also discovered for RF displacement (Dm_RF) in the LOW condition compared to CON immediately after the floss application. Despite there being no statistically significant differences when CON and HIGH wrapping pressures were applied, there were medium benefits in BF displacement (Dm_BF) associated with the HIGH condition compared to CON. The results show an acute improvement in neuromuscular performance, particularly after the LOW condition compared to CON and HIGH conditions.
To the best of our knowledge, this is the first study investigating the effects of tissue flossing on MVC or other neuromuscular parameters, when the floss band was wrapped around the thigh. However, similar short-term benefits for tissue flossing applied over the ankle joint on athletic performance in recreationally trained individuals were recently reported; \citet*{Driller_2017} demonstrated a significant increase in single-leg vertical jump test after only 2 minutes of floss band application; in addition, \citet{Driller_2017a} observed an increase in countermovement jump force and sprinting time up to 45 minutes after flossing. In contrast, tissue flossing seems to be less effective when applied to elite athletes \cite{Mills_2020}.
