The Influence of Interval Training Combined With Occlusion and Cooling on Selected Hemorheological Blood Parameters in Young Healthy People

Introduction: Changes in blood morphological and rheological parameters and the related mechanisms in the human body are still not fully understood. They should be subjected to constant revisions and analyses, not only specific, but also modified by external factors.Objectives: The aim of the study was to investigate and compare hemorheological parameters of blood during interval training combined with occlusion and cooling in young healthy people.Material and methods: 30 students of the University of Physical Education in Krakow were examined. The VASPER training system was used, offering the possibility of using occlusion factors and local cryotherapy with HIIT (High Intensity Interval Training) training at the same time. Blood from people participating in the project was collected six times (2 weeks before the start of training, immediately before the start of training, after the first training, after 10th training sessions, after 20th training sessions and two weeks after the end of training sessions). The subjects were divided into 3 groups: with occlusion and local cryotherapy, with occlusion and a control group (exercises only). Each person performed the same HIIT training routine, modified by factors depending on the assigned group.Results: In all groups, positive changes in hematological and rheological parameters were observed, occurring at a similar time and pace, regardless of the occlusion and local cryotherapy modifications used.Conclusions: The use of HIIT training using occlusion and cooling, occlusion alone and without additional modifications, can have a positive effect on hematological and rheological parameters in young healthy people and can be used to improve health and well-being. Further research is necessary to confirm the obtained results.
