Myths vs facts: Body-Balance Check | Testosteron-Test and Sport

Myths vs. facts: Body-Balance Check and testosterone tests for sports. Many companies claim that a DNA test can reveal your 'testosterone potential' or 'body balance' and provide personalized training. The scientific reality is sobering: testosterone levels are influenced by many factors – age, sleep, stress, diet, exercise type and intensity. Genetic variants (e.g., in AR or SHBG genes) usually have very small effects and are insufficient to derive individual training recommendations. The evidence for such tests is mostly mechanistic or based on weak association studies; randomized controlled trials proving benefit are lacking. Moreover, DNA tests do not measure current hormone levels – a blood test is required. A body-balance check based on genes is therefore more marketing than evidence-based medicine. Rely on proven methods: regular strength training, adequate sleep, stress management, and a balanced diet. For specific hormone concerns, consult a physician.
