Extreme physical strain: Tour riders lose muscle mass

Cyclists participating in the Tour de France reportedly lose muscle mass during the race. This phenomenon is caused by extreme physical strain, in which the body breaks down proteins from muscles to meet the high energy demand.

According to Bicycling Nederland, this is a normal process during prolonged, intense exertion. The body uses all available energy reserves, including muscle tissue, to maintain performance.

Sports scientists call this phenomenon catabolism. It is an adaptation mechanism to survive during the tough stages of the Tour. Riders can limit this loss by following a balanced diet and getting enough rest.

It is unclear whether this loss of muscle mass is dangerous for the riders. It is a common phenomenon among top athletes who undergo extreme strain.
