Analysis of Sport Supplement Consumption and Body Composition in Spanish Elite Rowers.
Abstract: The aim of this study was to analyze the anthropometric characteristics and sport supplement (SS) consumption patterns of heavyweight and lightweight international rowers. Methods: The 13 heavyweights (11 males) and seven lightweights (five males) of the Spanish National Rowing Team were recruited for the study. Body composition was measured by bio-impedance analysis, and the questionnaire used in this investigation was previously validated to assess SS consumption. According to anthropometrics parameters, it was reported that male heavyweight rowers were heavier (p < 0.001) and taller (p < 0.001), but no statistical di erences were reported for % body fat (p = 0.104) or % lean body mass (p = 0.161). All rowers reported consumption of at least one SS. Based on the Australian Institute of Sport’s classification, higher medical supplement consumption was observed when comparing heavyweight rowers to lightweight rowers (2.5 1.1 vs. 1.7 0.5, p = 0.040). There were no di erences in the totals of group A (strong scientific evidence for sports scenarios, p = 0.069), group B (emerging scientific support, deserving of further research, p = 0.776), or group C (scientific evidence not supportive of benefit and/or security amongst athletes, p = 0.484). The six most consumed SSs were iron (85%), ca eine (85%), -alanine (85%), energy bars (85%), vitamin supplements (80%), and isotonic drinks (80%), with no statistical di erences between heavyweight and lightweight rowers (p > 0.05). These results suggest that the absence of di erences in body composition (expressed as a percentage) do not represent anthropometric disadvantages for heavyweight rowers. In addition, SS consumption was similar between rowers, reporting only higher medical supplement consumption in heavyweight rowers.
