Summary:
- Ultramarathons are long-distance running events that exceed the traditional marathon distance of 26.2 miles. These races can have significant impacts on the human body.
- A recent study examined the metabolic changes that occur during an ultramarathon, including increases in fat and carbohydrate burning, as well as changes in various hormones and enzymes.
- The study found that runners experienced a shift towards greater fat burning during the race, which helps to preserve limited carbohydrate stores. This adaptation helps runners maintain energy levels over the extended distance.
