Is TSH Schilddrüse useful for Sport?

TSH (thyroid-stimulating hormone) is a marker of thyroid function. Thyroid disorders can affect metabolism, energy, and recovery, which are relevant for sport performance. However, TSH alone is not a direct performance biomarker. Routine testing in asymptomatic athletes is of unclear benefit. Evidence is mechanistic, not sport-specific. Caveat: single TSH values without clinical context are not actionable. If you experience fatigue or performance decline, consult a physician for proper evaluation.
