Bioelectrical impedance analysis is a method used for estimating body composition. This method estimates body composition based on the degree of current flow in the body, allowing noninvasive and rapid measurement, and is used in home-use body composition monitors and other devices.

However, existing estimation methods might not be sufficient for accurately assessing skeletal muscle mass in individuals such as athletes and active men, whose muscle quality and composition differ from those of the general adult population.

In this study, researchers from the University of Tsukuba evaluated the validity of bioelectrical impedance for estimating skeletal muscle mass specifically in athletes and active men.

Results revealed a strong correlation between and bioelectrical impedance indices, confirming that bioelectrical impedance is a useful tool for this purpose. The work is published in The Journal of Nutrition.

In addition, bioelectrical impedance is effective for estimating intracellular water levels. This finding is likely to encourage broader adoption of bioelectrical for assessments in medical institutions and fitness facilities, making evaluations easier and more accurate.

In the future, researchers anticipate the development of more precise estimation formulas, which will facilitate the evaluation of the effectiveness of training and nutritional interventions for . Moreover, the adaptability of these new formulas for diverse populations will be further investigated.
