Abstract
Description
Technical Field
[0001] The utility model belongs to the field of exercise equipment, in particular to a hamstring muscle trainer. Background Art
[0002] The hamstrings, as the main muscle group on the back of the thigh, including the semitendinosus, semimembranosus and biceps femoris, play an important role in the body's motor function. They are not only involved in hip extension and knee flexion, but also play a key role in maintaining knee stability, improving sports performance and preventing sports injuries. Insufficient hamstring strength may lead to imbalance in movement and increase the risk of anterior cruciate ligament injury, especially during high-speed movement and change of direction. Therefore, hamstring strength training is crucial for both athletes and ordinary fitness enthusiasts.
[0003] Traditional hamstring strength training methods focus primarily on eccentric training, which is a training method in which muscle fibers are stretched during muscle contraction. This training method is effective in improving hamstring strength and endurance, but often overlooks the importance of concentric training (muscle fibers shorten when muscles contract) and isometric training (muscles generate force without changing length). Concentric training helps improve muscle power, while isometric training helps increase muscle stability and endurance. In addition, multi-angle training can more fully activate different parts of the hamstrings, improving their adaptability in various sports scenarios.
[0004] Currently, there are few devices for Nordic hamstring training, and the only patents have certain limitations. Document number CN209734857U "A Hamstring Eccentric Trainer" provides a hamstring trainer with an auxiliary elastic band, which is suitable for ordinary training subjects with weak core strength through the auxiliary elastic band. The device provides a safety guarantee for training, but cannot provide additional load resistance and cannot monitor training parameters. Document number CN115253189A "A Nordic Hamstring Eccentric Training and Detection System" is equipped with a tension sensor and a pressure sensor, which can measure the force of the left and right legs in real time, and can provide additional resistance and buffering force, and monitor the training parameters in real time. However, the device can only achieve eccentric and concentric training under remote fixed conditions, which cannot meet the needs of athletes and rehabilitators for comprehensive training. In addition, there are problems with the design of the ankle fixation device, which may cause discomfort and skin damage during training. Utility Model Content
