Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
30 young, healthy people will take part in the study. They will be divided into 2 research groups: 2 intervention groups. Participants will be recruited through an advertisement posted at the University of Physical Education in Krakow. Allocation of individuals to different groups will be made by sampling volunteers. The subjects will be included in the research program after obtaining the consent of a rehabilitation physician and after consulting a physiotherapist (assessment of health and functional status).

The research will cover a group of 30 people:
1. 15 people Vasper Systems LLC training with the use of occlusion - interval effort consisting of 3 intervals of 6 minutes with maintaining an individually selected level of heart rate and 60 seconds of rest between intervals (about 20 minutes).
2. 15 people Vasper Systems LLC training with the use of occlusion and cooling - test scheme as in point 1 combined with a continuous cooling system provided by the cuffs used in the occlusion and cooling mats placed under the feet and in the sitting area.

Participants will be asked to alternate limb movements for 3 intervals of 6 minutes with individually adjusted heart rate and 60 seconds of rest between intervals, with calf and arm cuffs on. The pressure in the cuffs will be increased during the activity to limit blood flow to the legs and arms.

For both study groups:
the method of administering the interval training: one on one (individual training)
individually selected heart rate in consultation with a physiotherapist - lactate level test
training room temperature of 20 degrees Celsius
the cuffs temperature of 10 degrees Celsius
frequency and duration of sessions: 20-minute sessions three times a week
total duration of the intervention is approximately 10 weeks
strategies used to assess or monitor adherence to the intervention: session attendance checklists (100% attendance mandatory)

Outcomes
