Description

Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation equipment, in particular to a spring shoe for lower limb muscle resistance training. Background Art

[0002] Resistance training is a form of exercise that improves muscle strength and endurance. During resistance training, the limbs have to resist the resistance generated by body weight, gravity, elastic bands, weightlifting barbells or dumbbells. It is well known that when patients lack exercise, muscle atrophy is very rapid. Some patients need effective resistance training for lower limb muscle strength to avoid lower limb muscle atrophy and speed up recovery. It can be seen from the article "Classic Lower Limb Muscle Strength Resistance Knee Extension Rehabilitation Training" introduced at the website https: / / www.sohu.com / a / 274610352_466530 that when resisting knee extension, one method is to tie a sandbag of appropriate weight on the ankle as a load, kick forward with force when extending the knee, and hold for 3-5 seconds when resisting the weight of the sandbag until it is fully extended, which is considered to complete one action. Although this method is simple, it requires a sandbag of appropriate weight. As the ankle moves up and down, the sandbag will also hit the ground when moving down. When used for a long time, the sandbag is easy to be damaged, thereby delaying training. Therefore, in real life, it is urgent to design a convenient training device. Based on this, the utility model designs a lower limb muscle strength resistance training spring shoe to solve the above problem. Utility Model Content
