Description

Equipment for Blood Flow Restriction Training
Technical field of the invention
The present invention relates to equipment for Blood Flow Restriction (BFR) training.
Background of the invention
BFR (Blood Flow Restriction) training involves training while restricting blood flow to the muscles. BFR training is performed by winding an elastic band or cuff around the extremities (either legs or arms) while performing muscle activating actions, such as walking, cycling or strength training. The elastic band or cuff restricts the venous outflow of blood from the muscles. Thereby, blood will accumulate in the extremity and limit blood flow to the muscles. This will bring a greater metabolic stress in the restricted area, lead to elevated blood lactate levels, and result in the release of growth hormone and IGF-1 . Another benefit of BFR training is that fatigue can be obtained faster while using lightweight loads. By restricting the oxygen supply to aerobic motor units (pool of muscle fibres) a recruitment in anaerobic motor units will take place. Both mechanisms
upregulate molecular pathway signalling and protein synthesis, and BFR training can lead to muscle growth (hypertrophy) similar to what is seen training with heavy loads. The positive side-effect of using lightweight loads is that this reduces the mechanical stress on joints and ligaments making it very helpful in rehabilitating setups. BFR training is currently challenged by the fact that it is difficult to control the clamping of the blood supply to the muscles. If the bands or cuffs are positioned too tight, it is very painful and can in severe cases damage nerves (paresthesia) or arteries. If the bands or cuffs are positioned too loose blood flow restriction will not occur and the training effect will not be as desired.

Detailed Description of the Invention
The following describes a preferred embodiment. Figure 1 shows an BFR training device 100 comprising a valve unit 200 and a cuff 400. The cuff 400 is hereby shown transparent to better see the individual parts of the valve unit 200. The cuff 400 includes an inflatable bladder 300 and is adapted to become attached to an extremity of a human and exert a pressure on the extremity when there is air in the inflatable bladder 300. Here is shown a hook and loop fastener for aiding in the attachment of the cuff 400. However, in one or more
embodiments, the cuff 400 may be formed as a ring, through which the extremity (arm or leg) can be introduced. This configuration prevents the cuff from loosening during the workout. The valve unit 200 is attached to the cuff 400 and is in air communication (air can flow between the valve unit channel and the inflatable bladder) with the inflatable bladder 300. In Figure 1 , the valve unit 200 is mounted at the edge of the cuff. In Figure 2, the valve unit 200 is mounted on the surface of the cuff 400 at the edge of the inflatable bladder 300. In Figure 3, the valve unit 200 is mounted on the surface of the cuff 400 on the surface of the inflatable bladder 300.
The valve unit 200 comprises a valve 220 configured to be in an open position, a loading position, and a closed position. The open position allows air in the inflatable bladder 300 to leave the inflatable bladder 300 through the valve 220. The loading position allows the passage of air into the inflatable bladder 300 when connected to a pump 240. The closed position prevents air in the inflatable bladder 300 from leaving the inflatable bladder 300 through the valve 220.
The valve unit 200 further comprises a pressure sensor 230 configured to determine the air pressure within the inflatable bladder 300.
The valve unit 200 further comprises a transmitter 210 configured to wirelessly transmit the air pressure within the inflatable bladder 300, and measured by the pressure sensor 230, to a handheld computer device (not shown), such as a mobile phone.
The valve unit 200 further comprises an air pump 240 configured to pump air through valve 220 and into inflatable bladder 300 when valve 220 is in the loaded position. The air pump 240 is configured for wireless activation and deactivation.
The valve 220 can be set by a wireless signal to switch between the open position, the closed position, and the loading position, whereby the pressure inside the inflatable bladder 300 can be adjusted.
