What role does Body-Balance Check | Testosteron-Test play in Sport?

The role of the Body-Balance Check | Testosterone Test in sports is not supported by the provided knowledge context. The available information covers DNA tests for weight, obesity, longevity, and athletic performance (e.g., polygenic scores for endurance), but no specific testosterone test. While measuring testosterone levels (blood or saliva) can offer insights into hormonal status, its direct impact on sports performance optimization is limited. Evidence for performance enhancement through testosterone supplementation without medical indication is weak and carries health risks. Consumer tests often overstate their predictive value. Therefore, the evidence level is 'marketing' or 'unclear'. Athletes should rely on validated training, nutrition, and recovery strategies, and interpret hormone tests only under medical supervision.
