Introduction:
There is growing evidence supporting the use of interval training and/or low-impact blood flow restriction exercises for musculoskeletal rehabilitation. The aim of this study was to evaluate the effect of interval training combined with occlusion and cooling on lipid profile changes.
Materials And Methods:
The study included 30 young, healthy, and untrained people. The Vasper training system was used-high intensity interval training with the simultaneous use of occlusion and local cryotherapy. Blood samples were collected from the participants six times (2 weeks before the start of training, on the day of training, after the first training session, after the 10th training session, after the 20th training session, and 2 weeks after the end of training). The subjects were randomly divided into three groups: exercises only (controlled), occlusion, and occlusion with local cryotherapy.
Results:
Analysis of the results showed changes in the mean HDL values in the OCC-COO (F = 3.6868, p = 0.007744, Eta-squared = 0.315467) and OCC (F = 3.1597, p = 0.020789, Eta-squared = 0.344959) groups. Training in both groups resulted in a decrease in HDL levels, followed by stabilization.
Conclusions:
HIIT with occlusion and cooling, or occlusion alone, may negatively impact HDL levels in young, healthy individuals. Regular, submaximal interval exercise without additional modifications appears to be safe and has no negative impact on lipid profiles. Changes in HDL levels are observed after a series of training sessions, not after a single training session.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
