and Health
Bodybuilding has been around since ancient times, but it has evolved greatly over the years and continues to do so. Genetics are an important factor in how successful one is in their bodybuilding journey. While genetic makeup is something one cannot change, understanding its effects can maximize potential gains and help achieve desired body composition goals.
Genetic Variations
Different genetically-based conditions can affect a person’s capacity to build muscle and strength. Muscle fiber type is one such factor determined by genetics. There are two types of muscle fibers: fast and slow. The ratio of fast-twitch to slow-twitch muscle fibers affects an individual’s ability to build muscle quickly or have endurance-based results.
Genetic Predisposition
Genes are responsible for programming the way the body works and processes different types of physical activity. Endomorphs are naturally predisposed to having a higher body fat percentage, while ectomorphs are slimmer with less body fat.
It should be noted that these predisposed body types are not set in stone, and an individual’s lifestyle factors play a much larger role in shaping their body composition.
The Impact Of Genetics On Health
Genetics play a major role in a person’s overall health and wellness. Genes can influence everything from calorie burn rates to chronic illness. For example, a person’s ability to effectively metabolize cholesterol or efficiently rid their body of toxins may be genetically predetermined.
While genetic testing can be beneficial in informing lifestyle choices, it’s important to remember that genetic makeup is not a definitive indicator of overall health. Lifestyle habits, such as diet and exercise, will have a greater impact on general health and body composition than genetic predisposition.
Final Thoughts On Genetics & Bodybuilding
Genetics are undeniably a powerful factor in an individual’s bodybuilding progress and overall health outcomes. Knowing how genetic markers play into physical goals can be useful in creating a customized plan to help achieve those goals. Ultimately, an individual’s success in bodybuilding and health is contingent on lifestyle factors like adherence to diet and exercise, and not just genetics.
