The provided context contains no information about the LCT gene (lactase). Lactase is essential for digesting lactose in dairy. In sports, dairy can be a convenient source of protein, calcium, and carbohydrates, but lactose intolerance (often linked to the LCT-13910 C/T variant) may limit these options. Athletes with intolerance might choose lactose-free products or lactase supplements. However, the evidence for a direct role of LCT in athletic performance is weak and based on general nutrition principles rather than sport-specific genetic studies. Without relevant context, the answer remains conservative: LCT affects lactose tolerance, but its impact on sports performance is not well-established. Safety note: If lactose intolerance is suspected, consult a healthcare professional before making dietary changes.
