椭圆机的缺点[摘抄]

买了台椭圆机，FE500，可以边踩边看视频，然而，椭圆机也不可运动过度。

椭圆机的缺点，百度/so/sogou搜索到的信息很有限，翻墙用Google，查到椭圆机有如下缺点，

尽管椭圆机在锻炼身体方面有诸多好处，但椭圆机并不适合每个人，并且不应该成为唯一的运动来源。

• low-impact exercise you obtain does not provide an effective way to gain muscle strength，low-impact workout does not provide the bone-strengthening of weight-bearing exercises. 低冲击力锻炼并不能有效强化肌肉力量，不能提供负重锻炼的骨强化。您可能需要在日常工作中添加肌肉和骨骼强化练习。
• 尽管椭圆机器通常在膝盖上安全，但如果膝盖受伤或受伤，它们可能会导致膝盖疼痛

• The most common overuse injury on the elliptical involves the knee. Rick Kaselj, a kinesiologist and rehabilitation expert, says the elliptical forces your body to be in a fixed position that may not naturally be in your proper alignment. If your hips are wider than the foot pedals, then your knees may bow inward, putting stress on the medial area of the joint. The elliptical forces you to exercise on the balls of your feet, which engages the quadriceps muscles. This can pull on the patella, or kneecap, and can cause sharp pains on the top of the knee, also called patellar femoral syndrome. 椭圆上最常见的过度使用损伤涉及膝盖。 运动学家兼康复专家Rick Kaselj说，椭圆形强迫你的身体处于一个固定的位置，这可能不会自然地处于适当的位置。 如果你的臀部比脚踏板宽，那么你的膝盖可能会向内弯曲，对关节的内侧区域施加压力。 椭圆形的力量可以锻炼你的脚上的四肢，从而锻炼四头肌。 这可以拉髌骨或膝盖骨，并且可以引起膝盖上的剧烈疼痛，也称为髌骨股骨综合症。Exercising on the elliptical may exacerbate certain conditions and cause further harm. Whether the elliptical solely responsible for these injuries or they are only aggravated by it, it’s best to avoid the elliptical if you have them. According to Damien Howell Physical Therapy, these include any type of foot injury with pain on the ball of the foot such as collapsed arches, Morton’s neuroma, bunion or arthritis, because most elliptical work requires being on your toes. Avoid the elliptical if you have pain in the hips or bottom, also called piriformis syndrome, because the elliptical can further tighten the piriformis and worsen the condition. 在椭圆形上锻炼可能会加剧某些疾病并导致进一步的伤害。 无论是单纯为这些伤害负责的椭圆，还是仅由它们加重，最好避免使用椭圆。 根据达米恩霍威尔物理疗法，这些包括任何类型的足部疼痛，如摔倒的拱门，莫顿的神经瘤，拇囊炎或关节炎，因为大多数椭圆形工作需要在脚趾上。 如果你的臀部或臀部疼痛，也称为梨状肌综合征，避免椭圆形，因为椭圆形可以进一步收紧梨状肌并使情况恶化。The best way to prevent overuse injuries is the change your mode of exercise. The American Council on Exercise recommends 30 minutes of cardiovascular exercise on most days of the week. Change it up to include swimming, treadmill or cycling. It will keep you from falling into a rut and elicit better health benefits than just using one mode. Stretch after every workout to prevent muscle imbalances. After using the elliptical, stretch your quadriceps, calves, hamstrings and back to prevent excessive tightening. 防止过度使用伤害的最好方法是改变你的锻炼方式。 美国运动委员会建议在一周中的大部分时间进行30分钟的心血管锻炼。 改变它包括游泳，跑步机或骑自行车。 它不会仅仅使用一种模式，而使您不会陷入窘境并获得更好的健康益处。 在每次锻炼之后拉伸以防止肌肉不平衡。 使用椭圆形后，拉伸你的四头肌，小腿，腿筋和背部，以防止过度拧紧。

• Repeated flexion and twisting of the spine is known scientifically to encourage degeneration and cause pain.反复弯曲和扭曲的脊柱被科学地称为鼓励退化并导致疼痛。Individuals with lumbar disc problems should probably refrain from using the elliptical (just because it puts you in such a forward posture, something that should be avoided when at all possible if you are somebody with lumbar disc issues). She suggests that walking would be a much better form of exercise over an elliptical for people with lumbar disc problems.患有腰椎间盘突出问题的人应该不要使用椭圆形（只是因为它会让你处于这种前向姿势，如果你是腰椎间盘突出问题的人，应该尽可能避免这种情况）。她建议，对腰椎间盘突出症患者来说，步行是一种比椭圆形更好的锻炼形式。

• people tend to flex forward more while using the elliptical machine (hello tight hip flexors!!). And, even worse still, the elliptical forces people to twist in their lumbar spine, which if we’re speaking from a biomechanical standpoint, isn’t ideal given there’s only 13 degrees (roughly) of “acceptable” rotation in that area in the first place. 人们在使用椭圆机时倾向于向前弯曲（你好紧髋屈肌!!）。 更糟糕的是，人们在腰椎中扭曲的椭圆形力量，如果我们从生物力学的角度来讲，这是不理想的，因为在这个区域中只有13度（大致）“可接受”的旋转 第一名。
