Learn how genetics and lifestyle factors influence muscle growth from resistance training. Covers the science behind strength gains, from molecular pathways to genetic applications backed by research.
The ACTN3 gene codes for actinin alpha-3, a protein found in fast-twitch muscles. Some people don’t produce this protein, which changes the composition of their muscles. Elite athletes may be limited by this genetic change.
Do you end up getting sore after pretty much every workout at the gym? It could be that a deficiency caused by the AMPD1 genetic variant is the cause.
PPARδ is a key player in how and when your muscles burn fat for fuel. Genetic variants in the PPARD gene impact how well your muscles utilize fatty acids. These variants also impact how much of a fat-burning benefit you get from exercise.
Genes control the formation, composition, and type of muscle fiber. Learn how to optimize your training when genetics comes into play, affecting muscle composition and endurance.
