Effect of Tissue Flossing on Recovery Time After Intense Physical Exercise Causing Delayed Onset Muscle Soreness

The aim of the study is to assess whether soft tissue flossing therapy will alleviate eccentric muscle-destroying influences. Men aged 20-25 will be tested. Suddenly taking up activity in untrained people and performing the fatigue protocol is a heavy burden for the body, and its effects may have a negative impact on the body. The assessment of the processes taking place in the body under the influence of this type of physical activity with the use of soft tissue flossing will broaden the scope of knowledge about this therapeutic method and will allow assessing whether it has an impact on accelerating regeneration after intense physical exertion.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: soft tissue flossing therapy right lower limb; The study will be conducted in two rounds, 4 weeks apart. In round one, subjects will have their right leg flossed while performing the fatigue protocol.	Procedure: soft tissue flossing therapy; BFRT and tissue threading is a therapy that involves applying external pressure below or above a joint or muscle of a selected limb, usually with a circumferential elastic band. The pressure provided by the rolled band securely maintains arterial blood supply but reduces or blocks venous outflow distal to the site.; Other Names: Blood Flow Restriction Training; BFRT
Experimental: soft tissue flossing therapy left lower limb; The study will be conducted in two rounds, 4 weeks apart. In round one, subjects will have their left leg flossed while performing the fatigue protocol.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Isokinetic muscle strength	Measurements will be performed on an isokinetic dynamometer (Biodex Medical System 4-PRO, New York, USA). According to the manufacturer's protocol, the dynamometer will be calibrated before each test session. The gravity correction will be performed before each series of measurements. Before the intervention, participants will perform a 5-minute warm-up on the bicycle ergometer with a power of 120 W.	40 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Soft tissue assessment	Changes in quadriceps femoris stiffness will be assessed by myometry performed separately for six points marked on the muscle before the test.	40 days
Range of motion	Knee Range of motion will be measured with a 360° 14- inch hand held metal goniometer (Fabrication Enterprises, USA). During the measurement, the tested person will be in the supine position. A stabilizing belt will be placed at the height of the sacrum. The axis of rotation of the goniometer will be set at the height of the space of the knee joint. One arm of the goniometer will be aimed at the greater trochanter and the other arm at the lateral malleolus of the fibula. Landmarks for subsequent measurements will be marked on the first day on the subjects' bodies with a semi-permanent marker. Participants will be asked to perform maximum full knee flexion. The knee angle measurement will be repeated three times, and the average result will be included in further analysis.	40 days
Visual Analogue Scale (1-100 mm)	A Visual Analogue Scale will be was used to assess pain - the subjects will mark the level of pain perception on a colour scale (1-100 mm) immediately after all exercise tests where a value of 1 is attributed to no pain at all, and a value of 100 is the worst pain imaginable.	40 days
Pain assessment - Algometer	Measurement of the pain threshold under the influence of pressure on the muscle will be tested with a digital algometer "Digital Force Algometer" at six points marked on the muscle before the tests.	40 days
Triple hop jump test	In the triple jump test, subjects will perform the longest possible jump on one leg three times in a row. During the test, they must not lose their balance and must land safely. The distance will be measured from the starting line to the supporting heel.	40 days
