The article presents active mass quality (fat free mass, muscle mass) and segmental distribution of body fluids as a prerequisite of performance in elite female basketball players, silver medallists at 2010 World Championship. The collected data indicated the level of fat free mass (60.96 ±5.35 kg) and muscle mass (57.07±5.0 kg) at the level of elite athletes.
Fat mass showed lower percentage proportion than it is presented by available literature (14.34±2.37 %). Based on the gained data, it is not possible to definitely express a trend in proportion for individual playing positions.
Segmental distribution of body fluids revealed asymmetry in favour of a dominant upper limb (p ˂ 0.01), which indicate the need to perform exercises in order to compensate the detected bilateral deficit. In conclusion, the authors discuss the necessity of continual monitoring changes in body composition quality in terms of monitoring individual components of water or directly and indirectly measurable parameters in bioimpedance measurement, respectively.
