Physiologic testing is needed to more precisely determine the demands and adaptions in synchronized swimming. Because physique is important in performance scores, full anthropometric profiles are necessary to understand the optimal characteristics for this sport. Energy requirements and nutritional practices are unknown and the only controlled study suggests that underreporting food intake may confound future studies. Opportunities for fluid replacement and intake of nutrients and/or supplements may be limited in this sport, both by the physical limitations of training and the drive to achieve a certain physique. Nutritional education is hampered by the lack of information.
