How Genetics Shape Sports Performance: Endurance, Power, and Injury Insights

What is it about?

The study conducted a narrative literature review analyzing the interaction between genetic polymorphisms and environmental factors, such as training and nutrition, to determine their impact on athletic performance and injury risk. The research reviewed various sports, including football, rugby, and soccer, identifying significant genetic polymorphisms like ACTN3 rs1815739, ACE I/D, and VEGFA rs699947 that influence performance outcomes and injury susceptibility. It explored the role of nutritional supplements such as iron and caffeine, emphasizing the personalized nature of training and nutrition for optimal performance. Despite establishing correlations between genetic factors and athletic performance, the study acknowledged that elite performance results from a complex mix of genetic predisposition and environmental influences. The research highlighted advancements in genetic testing technologies, such as genome-wide association studies and Total Genotype Scores, but noted the need for further studies to understand the interaction of genetic and environmental variables. The findings confirmed the importance of genetic polymorphisms in athletic traits but stressed the necessity of additional research to make more precise associations.
