Summary

This study investigates the effects of blood flow restriction (BFR) training combined with low-intensity aerobic exercise on muscle oxygenation, total hemoglobin (THb), and blood lactate levels in elite athletes, comparing them with healthy sedentary individuals. BFR training, which partially restricts arterial and fully restricts venous blood flow using a pneumatic cuff, creates a hypoxic environment, leading to muscle strength and endurance improvements with lower-intensity exercise. The study aims to determine whether BFR-induced occlusion enhances muscle adaptation and how these physiological responses differ between elite athletes and sedentary individuals.

Conditions

  • Blood Flow Restriction Training
  • Muscle Oxygenation
  • Physiological Adaptations

Interventions

DEVICE

Blood Flow Restriction Kaatsu Training Device

The Blood Flow Restriction (BFR) intervention uses a pneumatic cuff to partially restrict arterial and fully restrict venous blood flow, creating a hypoxic environment that enhances muscle activation and strength at low exercise intensities. In this study, BFR will be applied intermittently during low-intensity treadmill walking with controlled pressure adjustments. The Moxy Muscle Oxygen Monitor is a non-invasive NIRS device that measures muscle oxygen saturation (SmO₂) and total hemoglobin (THb). Placed on the quadriceps femoris muscle, it will track oxygenation changes before, during, and after BFR exercise, helping assess muscle metabolism and performance adaptations.
