In this study, it was aimed to compare the effects of low load blood flow restriction exercise (LL-BFRE) training versus high load resistance exercise (HL-RE) training in healthy young individuals on the parameters of lower extremity muscle strength, dynamic and static postural balance, functional performance and cognitive performance.
In this randomized controlled study, there will be two study group. Study group 1 will recieve low load blood flow restriction exercise training and Study group 2 will recieve high load resistance exercise training for 6 weeks, 2 exercise sessions weekly.
At baseline assessment, individuals who met the inclusion criteria, informed by the researcher and accept the participate in the study, researcher will record the participants' sociodemographic and physical informations and then, asess the lower extremity muscle strength with Hand-held digital dynamometer, dynamic postural balance with Y-Balance Test-Lower Quarter, static postural balance with Single Leg Stance Test (Eyes open/closed condition), functional performance with 6-Minute Walking Test and cognitive performance with Stroop Word and Colour Test and Trail Making Test.
At the end of the 6 week exercise training all participants will undergo the same assessments.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Blood Flow Restriction Exercise Training (BFRT) | Experimental | Exercises will be performed under the supervision of a researcher physiotherapist, at low intensity and progressively, under blood flow restriction for 6 weeks, 2 days a week, for a total of 12 exercise sessions. The 1 MT method will be used to determine the amount of resistance in strengthening exercises. Blood flow restriction will be made by wearing a pneumatic tourniquet from the proximal thigh, within a safe pressure range specific to each individual. Blood flow restriction United States Food and Drug Administration Using the (FDA) approved H+Cuff device, it will be applied for 20 minutes, with a 1-minute break between exercises. The cuff pressure will be maintained during the rest period, and after the application, individuals will rest for 15 minutes to ensure reperfusion and other exercises will continue. |
|
| Conventional Exercise Training | Experimental | Participants who will be included in the conventional exercise group will apply the same exercise program as the participants in the blood flow-restricted exercise group, without blood flow restriction, for 6 weeks, 2 days a week, in a total of 12 sessions, at medium-high intensity. |

| High Load Resistive Exercise Training (HL-RE) | Other | HL-RE is a conventional, well known exercise method to enhance muscle strength and improve physical performance. It's performed by using resistance bands or weights applying on the extremity. |
|
| Baseline to 6 weeks after exercise training |
| Cognitive Performance | Cognitive performance will be assessed by using Trail Making Test. | Baseline to 6 weeks after exercise training |
| Cognitive Performance | Cognitive performance will be assessed by using Stroop Colour and Word Test. | Baseline to 6 weeks after exercise training |
Height (cm), body weight (kg) and body mass index (BMI) (kg/m2) will be measured. Height will be measure via stadiometer, body weight will be measure via weighing device and BMI will be calculated using with the formula "weight/height (m)2". |
