 The life expectancy of athletes depends on the sport they play. The entropagate concept, which has been successful in previous nutritional studies, will be used to assess the relationship between athletes' longevity and nutrition. Based on their calorie requirements, diets are designed for each athlete group according to the latest guidelines during their career and for the post-retirement period. Metabolic entropy generation is then calculated for each group. The expected average lifespan for male athletes is 56 years for cyclists, 66 years for weight lifters, 75 years for rugby players, and 92 years for golfers. If these athletes begin consuming a retirement diet at age 50, the cyclists can extend their lives by 7 years, weight lifters by 22 years, rugby players by 30 years, and golfers by 8 years.
