Tim mobilized the Tour de France bigger than usual

A recent study by the French University of Rennes showed that the hearts of the athletes participating in the Tour de France's largest bicycle race are 20% to 40% larger than the hearts of ordinary people.

The reason is that this race is the most intense bicycle race, while cycling is a top energy sport, so the Tour de France athletes' hearts have to be bigger and thicker to be able to Pump more blood to the body.

The study also added that after Tour de France athletes retired, their hearts gradually returned to normal size. The study also found that athletes with such large hearts are more likely to experience cardiovascular problems if they use stimulants.
