Article Synopsis
- The study investigated 22 elite male mountain runners from Brazil, focusing on how specific genetic variants affect their performance and physiological responses during a 105-km ultramarathon.
- Genotyping was done using saliva samples to analyze the ACTN3 R577X, ACE I/D, and CK MM A/G NcoI polymorphisms, and real-time measures of electrochemical and acid-base balance were recorded.
- Results indicated that certain genotypes correlated with differences in potassium levels, hematocrit values, and pH, suggesting that these genetic variations play a significant role in athletes' physiological responses during extreme endurance events.
Although the studied polymorphisms affect muscular proteins, aerobic adaptations, and recovery, their influence on the anthropometric variables and performance in ultramarathon runners is still poorly understood. This study aimed to determine the influence of , , and polymorphisms on the changes in the anthropometric variables and running time of 105 km mountain runners, in which 22 male Brazilian elite athletes (35.9 ± 6.
