![]() Genotypic and allelic frequencies were determined in 123 elite endurance athletes (75 professional road cyclists and 48 endurance elite runners) and 122 male non-athlete subjects (sedentary). The main objective of this work is to approach for the first time the study of genetic variants in liver-metabolizing genes and their role in endurance performance by comparing the allelic and genotypic frequencies in elite endurance athletes to the non-athlete population. “FGF21’s potential as a drug against diabetes, obesity, and similar metabolic disorders is currently being tested, so the fact that we are able to increase the production ourselves through training is interesting.The genetic profile that is needed to define an endurance athlete has been studied during recent years. It is still not clear what happens in the longer-term. One limitation of the new study was that it only looked at changes in the 3 hours following the exercise session. The team now plans to further investigate the links between metabolic hormones and exercise. As a hormone, it helps regulate bile acid production and metabolism of glucose and lipids.Īnimal studies have shown that, as well as helping with muscle growth, FGF19 can aid weight loss, reduce fats and glucose levels in the liver, and improve use of insulin. In fact, researchers have proposed that FGF21 has potential as a drug for treating “metabolic complications such as diabetes and fatty liver disease.”įGF19, which is produced in the gut, is described as an “atypical” member of the FGF family. These include, for example, cell growth, embryonic development, tissue repair, and tumor formation.įGF21 is produced in several organs and is active in weight loss, glucose control, and reducing inflammation. This was a surprise to the researchers who were expecting it to rise, since animal studies suggest that the metabolic hormone helps with muscle growth.įGFs are active in many different biological processes, in addition to helping regulate metabolism. The results also showed that levels of FGF19 fell slightly after strength training. Of particular interest is whether the hormone is directly involved in the health-promoting effects of cardio exercise. ![]() The effect of cardio on FGF21 was so marked that the researchers believe that it warrants further investigation. The results showed that blood levels of FGF21 rose significantly during the cardio or endurance sessions, but not in the strength training sessions. They used the blood samples to measure changes in levels of: blood sugar, lactic acid, several hormones, and bile acid. In the strength training session, they put all major muscle groups through a regime comprising five different exercises repeated between five and 10 times.ĭuring the 3-hour recovery period following each exercise session, the researchers took blood samples from each man immediately after exercise and then at intervals thereafter. In the cardio session, the men cycled at 70 percent maximum intake of oxygen. In the other group, the men did the strength training first and then the cardio.Īll the exercise sessions lasted for about an hour and were intensive. In one group, the men did cardio training first, and then strength training about a week later. They recruited 10 healthy young men and randomly split them into two groups. ![]() So, they investigated this further by examining the impact of two forms of exercise on metabolic hormones, which are the chemical messengers that regulate the processes of metabolism. However, while there is a lot of evidence outlining the various benefits of exercise on health, “the underlying mechanisms remain incompletely understood,” Clemmensen and his colleagues note in their study paper.
