There is no study investigating different volumes, that is various sets of the configuration of tissue flossing on neuromuscular function. Previously, investigators found that 3 sets of TF impaired neuromuscular function assessed with TMG. Therefore, the aim is to compare the effects of one and two sets of TS on countermovement jump (CMJ) performance and muscle contractile properties.
The primary purpose of the study will be to examine the differences in one and two sets of applying tissue flossing to the thigh muscles on neuromuscular function using tensiomyography (TMG) and CMJ, while considering several measurement points after flossing application (i.e., +0.5min, +3min, +6min, +9min, +12min, +15min). A better understanding of the effects of flossing on acute performance enhancement as well as on individual muscle contractile properties could help practitioners to develop specific pre-conditioning activities and consequently improve athletic performance on the field. The investigators hypothesized that: (i) the application of tissue flossing will improve the contraction time of the vastus lateralis muscle as well as the maximal jumping performance, regardless of sets of configuration.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| One set of muscle flossing | Experimental | This group will receive one set of muscle flossing around the thigh with low pressure. Pressure will be individualized based on thigh circumferences. |

| Tissue flossing | Procedure | After the standardized warm-up, participants will be instructed to stand still with their legs shoulder-width apart. The floss band (1.3 mm thick, 50 mm wide, 2 meters long, and strength level 3), consisting of a thick elastic latex band (COMPRE Floss, Sanctband), will be applied bilaterally around the distal third of the thigh. The applied pressure will be individualized by thigh circumferences, whereas low target pressure was chosen for this study, showing potential to elicit the most beneficial outcomes following flossing. The pressure will be monitored by the PicoPress device, which was placed at the middle distance of the application of the floss band to ensure that the entire surface of the pressure sensors was always completely covered. The flossing will be applied for 2 minutes with 2 minutes rest between sets. During flossing application subjects will be instructed to conduct 10 deep squats followed by 15 repetitions of knee extensions without added weight. |
| Measure | Description | Time Frame |
|---|---|---|
| Tensiomyography | We will use TMG to assess PAP from pre to post-different tissue flossing procedures. The contractile properties of the individual muscles will be assessed by the non-invasive TMG method. We will measure the vastus lateralis muscle of the dominant leg only. | 20 seconds per single measurement |
| Countermovement jump | Countermovement and squat jumps will be used to assess muscle fatigue from pre to post-different Vo2max testing procedures. Jumping ability will be assessed by vertical jump tests, using a bilateral force plate (model 9260AA6, Kistler, Switzerland) with Kistler MARS software to record ground reaction force data. | 30 seconds per single measurement |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of perceived exertion | Rate of perceived exertion will be measured to assess subjective perception of the fatigue from pre-to post flossing procedure | 5 seconds |
