If you feel that some people are better at exercising or just have it easier, then, you might actually be right. While some are always ready for a jog to the nearest gym, others might find themselves feeling daunted by the idea of doing something which causes shortness of breath or perspiration.
According to scientists, a link has been found between a person’s ability to efficiently workout and certain genes. Published in the New England Journal of Medicine, the researchers discovered that some people have a genetic mutation which makes it harder for them to exercise. Cellular oxygen sensing is impacted by genetic mutation and is linked to an individual’s ability to effectively workout.
The King’s College London researchers involved have found that certain people that have the gene had a high number of red blood cells, a limited workout capacity, persistent low blood sugar, and a reduced rate for growth.
One case study was tested by the research to determine why people had a limited capacity to exercise and behaved in such a way. Numerous tests were conducted which include high-altitude testing and genetic analysis. The scientists managed to discover that the Von Hippel-Lindau (VHL) gene is the mutated gene.
This VHL gene plays a huge role in genetic make-up because it helps cells survive when the ability to inhale oxygen gets reduced. People who struggle to exercise are believed to have a VHL gene that has been impaired according to scientists. The reason behind this is the fact that the gene is associated with the mitochondria as it does not fire on all cylinders in people that have the mutated VHL. Thus, it becomes difficult for such people to people.
According to Dr. Federico Formenti of the School of Basic and Medical Biosciences, the discovery of such mutation and the phenotype offers a much deeper understanding of our human physiology, especially when it comes to our senses and the way our body responds to a reduction in the availability of oxygen. The study also goes a long way in explaining why certain individuals can run for a marathon through training, while others might struggle and would not be mentally motivated to train.
This study provides a greater understanding of genes and their impact on our ability to exercise. However, more research will be needed to find out just how much of this gene mutation affects people. But, it is a great place to start and study more about the link between genes and our ability to exercise.
