Segmental bioimpedance analysis in professional cyclists during a three week stage race
Abstract
Bioelectrical impedance analysis has been widely used in the clinical and sport areas because it is a safe, non-invasive, rapid and inexpensive technique that evaluates some electrical properties of the body, such as resistance (R), reactance (X c ) and phase angle (PhA). The aim of this study is to evaluate body composition changes in professional cyclists, participating at the Giro D'Italia 2012, a three week stage race, and in particular PhA modifications as an expression of fat free mass nutritional status. Data were collected at the beginning, in the middle and at the end of the competition. Body weight, circumferences, skinfold thickness and BIA variables (total and segmental body) were measured. Body composition, measured by skinfold thickness, changed during the competition: fat free mass increased, but not significantly, in the middle and at the end of the competition, whereas fat mass significantly decreased versus the baseline in the middle and at the end of the competition. The total PhA did not significantly change in the middle of the competition but was significantly reduced at the end. The arm PhA did not change significantly at both times of the competition, whereas a significant reduction was reported for leg PhA in the middle and at the end of the competition. These results suggest the use of bioimpedance analysis, in particular PhA measurement, to monitor athletes' fat free mass characteristics during medium- and long-term competitions.
