Background. Occlusion pressure intensity influences the blood flow intensity. Immediately after the cuffpressure is released, reactive hyperaemia occurs. Increased blood flow and nutritive delivery are critical for ananabolic stimulus, such as insulin. The aim of study was to find which occlusion pressure was optimal to increase thehighest level of post occlusion reactive hyperaemia.Methods. Participants were randomly assigned into one of the four conditions (n = 12 per group): control groupwithout blood flow restriction, experimental groups with 120; 200 or 300 mmHg occlusion pressure. We used venousocclusion plethysmography and arterial blood pressure measurements.Results. After the onset of 120 and 200 mm Hg pressure occlusion, the blood flow intensity significantlydecreased. Occlusion induced hyperaemia increased arterial blood flow intensity 134 ± 11.2% (p < .05) in the groupwith 120 mmHg, in the group with 200 mmHg it increased 267 ± 10.5% (p < .05), in the group with 300 mmHg itincreased 233 ± 10.9% (p < .05). Applied 300 mmHg occlusion from the 12 minute diastolic and systolic arterialblood pressure decreased statistically significantly.Conclusions. Occlusion manoeuvre impacted the vascular vasodilatation, but the peak blood flow registeredafter occlusion did not relate to applied occlusion pressure. The pressure of 200 mmHg is optimal to impact thehigh level of vasodilatation. Longer than 12 min 300 mmHg could not be recommended due to the steep decrease ofsystolic and diastolic blood pressures.
