Abstract
This chapter presents the possibility of using multifrequency bioimpedance analysis (MFBIA) in sports practice. It is structured in the following sections: Introduction, The Use of BIA in Sports and Characteristics of the Selected Parameters of the Bioimpedance Method in Sports-The Use of Directly Measurable Parameters in Sports, The Use of Indirectly Measurable Parameters for Assessment of Performance and Measurement of Morphological Asymmetries Using BIA.
This chapter presents bioelectrical method in sports in terms of description of its potential use in sport, conditions for the use of BIA in athletes and validity and reliability. The authors present effect of a given sport on active components (lean body mass, body cell mass, muscle mass, intracellular mass, intracellular water, phase angle) and inactive on fat mass.
Part of the chapter is to practice outputs of elite male and female athletes and the differences between higher- and lower-level performance athletes, gender differences and differences during ontogenetic development and before and after sport performance. The chapter concludes with a special subchapter while discussing morphological asymmetries detected using multifrequency bioimpedance (proportion of muscle mass, fat mass and phase angle in the limbs where the BIA can be a useful tool for identification of morphological asymmetries in "unilateral" uncompensated sport activity).
