Što može otkriti analiza sastava tijela o snazi inspiracijskih i perifernih mišića?

Introduction: Body composition analysis measured with bioelectrical impedance analysis (BIA) is a method which has been frequently used in body composition assessment. The goal of this research is to determine the correlation of the derived measurements with the help of BIA with the strength of peripheral and inspiratory muscles as well as with the diaphragm’s function and thickness in healthy population. Participants and methods: Participants in this research were healthy individuals. They were tested on body composition with the help of bioelectrical impedance on Tanita MC-780MA device, maximal inspiratory pressure (MIP) with the POWERbreathe device, dynamometry of forearm muscle flexor and tibia extensor with the help of a dynamometer as well as ultrasound evaluation of diaphragm’s function. Results: The study sample consisted of a total of 50 participants, including 31 females (62%) and 19 males (38%) with a mean age of 41 years. The results have proved that the strength of peripheral and inspiratory muscles together with the diaphragm’s thickness and mobility are in strong correlation with muscle mass, sarcopenic index and phase angle measured by BIA. Conclusion: Bioelectrical impedance analysis is a reliable and practical method for assessing body composition and detecting early signs of muscle dysfunction. The established associations with muscle strength and diaphragmatic function highlight its potential as a simple screening tool for maintaining muscular health in clinical and preventive settings.
