The implementation of regular exercise has proven and confirmed great benefits and it enables long and independent life. Providing healthy musculoskeletal system can be crucial when trying to maintain a healthy life. Practicing resistance training has proven to be an excellent training operator for maintaining bone and muscle mass as well as for increasing muscle mass. In order to encourage significant changes in the body, especially in lockomotor system, it is recommended to practice resistance training with loads heavier than 70% of 1 repetition maximum (1RM). Higher loads stimulate the activation of fast Type 2 muscle fibers and lead to changes in the muscle such as the occurrence of hypertrophy and an increase in strength. But to perform this type of training it is necessary to be physically healthy so that the body can withstand great efforts. Such training is not recommended for the elderly, people in the process of rehabilitation or anyone who should not work with heavy loads. That is why the appearance of occlusal or training with reduced blood flow is of great interest to scientists. With this type of training, with the help of an external device that is placed on the extremity that performs the work which can be a cuff or tensioning band, the effect of occlusion is achieved by reducing the blood flow with the aim of achieving this in venous but not arterial flow. This way blood can enter the muscle and come out in a much smaller amount or be completely retained in the muscle. This leads to the accumulation of blood, which leads to swelling of the cells in the muscle and the creation of anaerobic working conditions or a feeling of work with a heavy load. A significant part of the implementation of this type of training is that the exercise can be performed at 20% 1RM to a maximum of 50% 1RM and the changes and effects in the body are similar to working with a large load of 70% 1RM onwards. For these reasons, the potential of this method of training is very significant as it can be applied to the elderly, injured individuals and people who are in the process of rehabilitation. A lot of research has been done on this topic both on people who practice exercising regularly, on the elderly and even on people who do not have the ability to move. In most of the results, the blood flow restriction training showed positive results, especially when it comes to muscle growth and no negative consequences were recorded.
