Tissue Flossing and Lower Limb Neuromuscular Function

Not Applicable

Completed

• Conditions: Tissue Flossing; Physical Performance; Neuromuscular Function; Ischemic Preconditioning
• Interventions: Procedure: Tissue flossing

• Registration Number: NCT05219344
• Lead Sponsor: University of Ljubljana

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Two sets of muscle flossing	Tissue flossing	This group will receive two sets of muscle flossing around the thigh with low pressure. Pressure will be individualized based on thigh circumferences.
One set of muscle flossing	Tissue flossing	This group will receive one set of muscle flossing around the thigh with low pressure. Pressure will be individualized based on thigh circumferences.

Primary Outcome Measures

Name	Time	Method
Tensiomyography	20 seconds per single measurement	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.
Countermovement jump	30 seconds per single measurement	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.

Secondary Outcome Measures

Name	Time	Method
Rate of perceived exertion	5 seconds	Rate of perceived exertion will be measured to assess subjective perception of the fatigue from pre-to post flossing procedure
