Combined Assessment of Body Composition and Neuromuscular Performance in Clinical Practice.

The assessment of body composition and neuromuscular performance provides valuable information for the clinical management of athletes and diverse patient populations. This protocol describes the combined use of a multifrequency bioelectrical impedance analyzer and a force analyzer to obtain biomarkers of muscle mass and function. The bioelectrical impedance analyzer measures the body's impedance to alternating electrical currents at selected frequencies, enabling the estimation of body composition parameters. The force analyzer detects vertically applied forces during sit-to-stand movements, including single, two-times, or three-times chair stand tests, allowing the evaluation of neuromuscular performance. Both assessments are simple to perform, noninvasive, and provide results quickly through automatically generated reports. The combined analysis of body composition and neuromuscular performance offers a practical approach for characterizing physical performance in athletes and functional and health status in clinical populations. This protocol may facilitate routine monitoring and support individualized training, rehabilitation, and clinical management strategies and outcomes.
