Blod flow restriction training is a unique training method with visible results even with low load. Ishemic stimulus that occurs in blod flow restriction training can have hypertrophic effects already with 20% 1RM. In addition to the increase of the cross-sectional area and muscle mass, studies also report of increased aerobic capacity, increased muscular strenght and increased maximal muscle strenght. Partial occlusion in the limb generates ishemic and hypoxic environment, which causes certain physiological adaptations to the training. Studies have shown that blod flow restriction training also affects the nervous system activity, where we can affect the activation and recruitment of fast-twitch muscle fibers. Despite scepticism regarding disrupted hemodynamics and concerns about ishemia-reperfusion injuries, blod flow restriction training proved to be safe. Correct application and exectution should not present any greater health risks than classic weight training. Its usefulness can in any case be seen in the early stages of rehabilitation. Using this method is also suitable when working with older population, for whom high intensity training presents too much physical burden. Some authors even emphasize the suitability of blod restriction training for cardiac rehabilitation. Considering the reduction of cardiac preload (ventricular filling), blod flow restriction training could be performed by patients with cardiovascular diseases.
