What do studies say about TSH Training?

The query about 'TSH Training' cannot be answered from the provided context. The documents contain no studies or statements regarding TSH (thyroid-stimulating hormone) in relation to training. TSH is a hormone of the thyroid axis that can be influenced by exercise, diet, and circadian rhythms, but the given texts only cover DNA variants (MTHFR, VDR, APOA5, LEPR, TCF7L2), biomarkers (AMH, IL-6, CRP), and general nutrigenetics. Without specific sources or data, an evidence-based response is not possible. It would be speculative to answer about TSH training based on this information. Instead, one should refer to endocrinological literature or training studies that include TSH measurements.
