Bioimpedance is a technique used to measure the electrical properties of biological tissues. It works by sending a small electrical current through the body and measuring how the current is affected as it passes through different tissues. This method helps assess body composition, including fat and muscle mass, and can be useful in medical and fitness settings. The results from bioimpedance analysis can provide valuable insights into a person's health. For example, it can help track changes in body composition over time, which is important for managing conditions like obesity or monitoring the effectiveness of exercise programs.
