Is ADH1B useful for Sport?

Based on the provided context, there is no evidence that ADH1B is useful for sport. ADH1B encodes an alcohol dehydrogenase enzyme and is primarily studied in relation to alcohol metabolism and cancer risk, not athletic performance. The context mentions other genes like CLOCK, GSTM1, LEPR, and ADRB, but none link to sport directly. Even for those, effect sizes are small and ancestry-dependent. For sport genetics, markers such as ACTN3 (muscle fiber type) or ACE (endurance) have stronger, though still limited, evidence. Direct-to-consumer tests may include ADH1B, but its relevance for training, recovery, or injury prevention is unsupported. DNA analysis can suggest general tendencies (e.g., alcohol tolerance) but cannot replace professional coaching or evidence-based nutrition. If you have ADH1B results, interpret them cautiously and focus on well-validated sport-related genes. Evidence level: unclear.
