The complication of "less exercise" can affect anyone, and if it is not diagnosed or treated, it can affect sports performance and cause serious and long-term health problems.

The symptoms of this disease in women have been better studied; Only last month, Navarro, a tennis player, announced that he was suffering from it and announced that he would retire from the competition by 2027.

But men are equally exposed to this syndrome, and due to social stigma and the lack of clear warning signs, the disease may remain unknown for a longer period of time; For this reason, many of them, like Smith, suffer in silence.

BBC Sports explains what this disease is, how it affects men and women, and why, despite its prevalence and severity, wasting in sport is still an under-reported and somewhat neglected area of sports science.

Lack of physical activity can lead to bone loss, sleep disturbances, fatigue and low mood. If this disease is not treated, it can lead to serious and long-term problems such as osteoporosis, cardiovascular diseases and fertility problems.
