ICMR-NIN Study Reveals Athletic Training Impacts Body, Metabolism, Gut Health
A study by the National Institute of Nutrition found that long-term athletic training changes the body in different ways depending on the type of sport.
Endurance athletes, like runners, are leaner and burn more fat at rest.
Strength athletes, like weightlifters, have more muscle and stronger bones.
The study also found that the gut bacteria of athletes are different from those who are not active, and even differ between endurance and strength athletes.
This shows that exercise benefits the body in many ways, including how it uses energy and supports digestion.
The researchers suggest that personalized nutrition and training plans could help athletes perform better and stay healthier.
Long-term athletic training significantly influences body composition, metabolism, and gut microbiome.
Endurance athletes are leaner and burn more fat at rest.
Strength athletes have greater muscle mass and higher bone mineral density.
Gut microbiota differs between endurance and strength athletes, as well as compared to sedentary individuals.
Personalized nutrition and training strategies could optimize athletic performance and health.
