26岁女孩长期久坐，患上“死臀综合症”，网友：狠狠代入了……

The 26-year-old woman, who prefers to be called Dai, had been experiencing discomfort in her lower back for the past two months. The discomfort escalated to unbearable pain during extended periods of sitting.

Initially, Dai attributed the discomfort to a lack of exercise. However, she noticed knee pain after jogging recently, prompting her to seek medical help. 

During her hospital visit, doctors observed that Dai had weakened buttock muscles. She revealed that as an interior designer, she often worked long hours, sitting for over 10 hours a day.  

The doctor diagnosed her with "dead butt syndrome," also known as gluteal amnesia. 

gluteal /ɡluːˈtiːəl/ adj. 臀肌的

"Dead butt syndrome" primarily occurs when the gluteus medius, one of the three main muscles in the buttocks, weakens due to prolonged sitting. This weakening can impair the muscles' ability to function optimally, leading to poor shock absorption and reduced motion control of the hip and leg.

It marks a tug of war in your body: Over time, a sedentary lifestyle can cause your hip flexors to tighten — and the gluteal muscles to lengthen, which leads to inefficient muscle activation. 

sedentary /ˈsed(ə)ntri/ adj. （人）惯于久坐不动的

Both muscles need to shorten and lengthen in an opposing fashion. But that interconnected function is compromised when range of motion is restricted, It also makes other muscles work harder to compensate. 

It doesn't mean your butt is "dead": The term is symbolic. "Your muscles are still there, It's more that they're not activating efficiently." Such "death" or deconditioning occurs far more quickly than the time required to reverse the effects. It takes nearly twice as long to revive a dying butt with exercise and movement than it does to develop the condition.

It may cause symptoms elsewhere: Some people with dead butt syndrome feel discomfort in places far from the namesake spot. That's because, physically speaking, "everything is connected," Tight hip flexors can trigger back pain. Weak glutes can cause balance issues as well as knee and foot pain.
