Why elite cyclists should talk to astronauts

It is well known that the bones of astronauts can become weak from being in space. But did you know that elite cyclists can lose a similar amount of bone density during a racing season? A new study by our sports science experts has found that something called Relative Energy Deficiency in Sports (RED-S) is the main culprit. RED-S not only puts the cyclists at risk of fragile bones and fractures but can also negatively affect their race results. However, there is a way to combat this and our researchers have looked at what works. Race performance Cyclists who improved their nutritional intake and added strength exercises into their training improved their race performance, gaining an average of 96 British Cycling racing points over six months, compared to those who didn't adapt their training plan. Their bone density in their lumbar spine (lower back) was also much better compared to the cyclists who kept their diet and training plan the same. Adequate fuelling before, during and after training sessions made a difference, including intake of protein and carbohydrates within 30 minutes of a session.
