Trained vs. Untrained: Lower Extremity Pressure Changes
Research shows that how well oxygen moves from the lungs into the blood (called lung diffusing capacity) is linked to a person's aerobic fitness and endurance training. People who exercise regularly often have different lung and heart responses than people who do not. The exact reasons for these differences are still unclear. This study will test one possible explanation: highly trained people may handle changes in the amount of blood returning to the heart differently than people who are not trained. We want to learn how the blood vessels in the lungs react when the amount of blood entering the heart changes, and how this reaction is affected by fitness level. To do this, we will change how much blood returns to the heart by applying air pressure around the legs, similar to a light vacuum. These changes are expected to be similar to what happens when someone moves from lying down to standing up.

Physiological and Biochemical Responses to Blood Flow Restriction Training
This study is designed to examine the short-term and long-term effects of blood flow restriction exercise training on physiological and biochemical markers in individuals who are new to strength training and in experienced athletes training at different load levels. This exercise method involves placing a special inflatable cuff around the upper part of the thigh. The cuff partially limits blood flow to the area, which helps the muscles work more effectively during exercise. The cuff will be applied only to the individual's dominant leg (the leg you use more often in daily activities), but all exercises will be performed using both legs. The exercise program will last for a total of six weeks and will be carried out twice per week. The pressure applied by the cuff will be individually adjusted based on each participant's physical characteristics to ensure safety and comfort. The study will include a total of 30 healthy participants aged between 18 and 40 years. Participants will be divided into two groups: individuals who have recently started strength training and experienced athletes with different levels of training experience.
