人体工程学又称人机工程学，指的是合理地在设计中应用人机工学，能够提高老

Ergonomics, also known as ergonomics, refers to the rational application of ergonomics in the design, which can improve the safety factor and comfort level of the elderly during exercise. When designing fitness equipment for the elderly, it is necessary to reduce the safety risk of the elderly when using the fitness range according to the physical strength of the elderly. Ergonomics is not only the theoretical basis for designing fitness equipment for the elderly, but also the design principle that makes fitness equipment easy to use, reasonable in size design, more complete structure, and more ornamental. Because of the decline in body function, the aging of different body parts such as muscles and joints, and the decline in perception, it is difficult for the elderly to complete strong and sustained movements. Therefore, when designing fitness equipment for the elderly, we must fully understand the range of activities that each part of their body can withstand. For example, the elderly prefer the easy-to-operate spacewalk machine, which allows the elderly to exercise the muscles of the abdomen and legs, but at the same time it is also easy to cause the elderly to be injured during exercise. Older people have less water in their leg muscles and lack elasticity and toughness. When swinging their legs, they tend to hurt the muscles around the spine. , 3-4 seconds / time is more suitable. The grip strength of the elderly is 38.83kg for men and 18.79kg for women; the back strength is 51.48kg for men and 28.79kg for women; the leg strength is 25.31kg for men and 26.13kg for women. Therefore, when designing fitness equipment for the elderly, pay more attention to the range of strength that the various parts of the elderly body can bear, so that the operation is simple, safe to use, and moderate in strength, and fully consider the experience and feelings of the elderly when using. Considering the comprehensiveness of ergonomics, the design of fitness equipment should allow the elderly to have a pleasant, relaxed, and peaceful state of mind during exercise, to avoid the elderly from feeling unwell, irritable, and psychologically Unexpected situations caused by the ups and downs of It is necessary to make use of the ergonomic theory to make the structure design of outdoor fitness equipment more perfect, ensure safety and reduce the difficulty of operation.

人体工程学又称人机工程学，指的是合理地在设计中应用人机工学，能够提高老年人运动时的安全系数和舒适程度。在为老年人设计健身器材时要根据老年人身体强度的承受范围，降低老年人使用时的安全风险。人机工学既是为老年人设计健身器材时的理论基础，也是让健身器材使用方便、尺寸设计合理、结构更加完善、观赏性更强的设计原理。因为身体机能的下降，肌肉、关节等不同身体部位的老化，感知力的下降，老年人很难完成力量型和持续性较高的动作。所以在为老年人设计健身器材时要充分了解他们身体各部位所能承受的活动范围。比如说老年人比较喜欢容易操作的太空漫步机，它可以让老年人锻炼腹部和腿部的肌肉，但同时它也很容易使老年人在锻炼时受伤。老年人的腿部肌肉中水分较少，缺乏弹性和韧性，在摆动腿部时容易拉伤脊柱周边的肌肉，所以太空漫步机摆腿结构处的夹角应为45°左右，速度不能太快，3-4秒/次较合适。老年人的握力平均为男38.83kg、女18.79kg；背力平均为男51.48kg、女28.79kg；腿部力量平均为男25.31kg、女26.13kg。所以在给老年人设计健身器材时要较多的注意老年人身体各部位所能承受的强度范围，做到操作简单、使用安全、强度适中，充分考虑老年人在使用时的体验和感受。以人机工学的综合性来考虑，健身器材的设计应当可以让老年人在锻炼时有一种愉快、轻松、平和的心境，避免老年人在锻炼时因心情不畅、气血不顺、心理上的大起大落导致的意外情况发生。要利用人机工学的理论，让户外健身器材的结构设计更加完善，保障安全的同时降低操作难度。

Ergonomics, also known as ergonomics, refers to the reasonable application of ergonomics in the design, which can improve the safety factor and comfort level of the elderly when they exercise. In the design of fitness equipment for the elderly, it is necessary to reduce the safety risk of the elderly when using according to the bearing range of their physical strength. Ergonomics is not only the theoretical basis for the design of fitness equipment for the elderly, but also the design principle of making fitness equipment easy to use, reasonable size design, more perfect structure and more ornamental. Because of the decline of body function, the aging of muscles, joints and other different body parts, and the decline of perception, it is difficult for the elderly to complete high strength and sustained movements. Therefore, when designing fitness equipment for the elderly, we should fully understand the range of activities that their body parts can bear. For example, the elderly prefer the easy-to-use space walkers, which can let the elderly exercise their abdominal and leg muscles, but at the same time, it can also easily hurt the elderly during exercise. The leg muscles of the elderly have less water, lack of elasticity and toughness, and are easy to pull the muscles around the spine when swinging the legs. Therefore, the included angle of the leg swinging structure of the space walking machine should be about 45 ° and the speed should not be too fast. 3-4 seconds / time is more appropriate. The average grip strength of the elderly is 38.83kg for men and 18.79kg for women; the average back strength is 51.48kg for men and 28.79kg for women; the average leg strength is 25.31kg for men and 26.13kg for women. Therefore, when designing fitness equipment for the elderly, we should pay more attention to the strength range that each part of the elderly's body can bear, to achieve simple operation, safe use, moderate strength, and fully consider the experience and feelings of the elderly when using. In consideration of the comprehensive ergonomics, the design of fitness equipment should enable the elderly to have a happy, relaxed and peaceful mood during exercise, so as to avoid the unexpected situation caused by the old people's poor mood, Qi and blood, and psychological ups and downs during exercise. It is necessary to make use of the theory of ergonomics to make the structural design of outdoor fitness equipment more perfect, ensure safety and reduce the operation difficulty.<br>
