HUR pneumatic strength instrument is widely used in competitive sports, fitness rehabilitation, muscle system strength detection and evaluation and other fields.

HUR replaced the cam technology used in the counterweight trainer with unique technology, thus realizing the simulation of actual movement on the instrument. In sports training, muscle changes with the changes of muscle movement range, contraction speed and load. At the beginning of the movement, due to the influence of inertia, the conventional counterweight trainer needs a lot of force to move the counterweight. Once the counterweight moves, it only needs a small force to maintain the movement, and at the end of the movement, it needs a force in the opposite direction to make the counterweight move from the movement to the rest. Therefore, the counterweight training equipment can only have a large initial resistance, and once it moves, the resistance will soon fail, and the training effect is not ideal.

HUR uses pneumatic technology instead of counterweight and cam technology, and provides resistance for trainers through computer-controlled pneumatic pump. No matter whether the movement speed is high or low, HUR equipment can provide stable load resistance that changes according to the actual movement law, which realizes high-speed training under high intensity and greatly improves the quality and effect of strength training. High-speed training is very important in competitive sports strength training. No matter running, jumping, throwing and kicking, the muscle system must produce strength in a short time, and how to maintain the balance of the body also requires the ability of coordination and control in the state of rapid movement. High-speed training is also of great significance to athletes' injuries, because a large number of studies show that many injuries occur because the injured neuromuscular system does not respond quickly enough to external forces that may cause injuries.

Therefore, HUR equipment, whether it is slow or high-speed training, will get very ideal training results, especially suitable for training high-level athletes to improve special strength.
