Summary:
The aim of this study was to determine the physiological responses of Synchronized Swimming athletes, during technical routine in two different conditions of apnea. In this study 17 Junior Synchronized Swimming athletes, members of National Team (Mean age 17,3±1,69 years, body masst 53,9 ± 3,8 kg, height 1,67 ± 0,04 m) participated. The determination of maximal oxygen consumption, during 400m. maximum intensity swimming was performed in the first experimental day. The lactate threshold determined on 4 x 200 m. progressively increasing swimming intensity in another day. In two more different days a synchronised swimming technical routine executed. At the first condition the elements with apnea executed first in contrast with the second condition, where the apnea elements executed last. Heart rate was recorder during the routine and oxygen consumption and lactate concentration was recorded during recovery time. Similar values of oxygen consumption (42,3 ± 5,47 vs 42,94 ± 5,5 ml∙kg-1∙min-1) and lactate concentration (4,39 ± 0,87 vs 5,05 ± 0,84 mmol/l) were found for the athletes in both conditions of apnea. Heart rate was found higher in the condition with apnea last (153 ± 6 vs 136 ± 5 b/min, p<0,05). Furthermore, heart rate as percentage of the anaerobic threshold heart rate was found higher during the condition with the apnea last (29,21% vs 42,33%). This demonstrates that the routine in which the placement of apnea is designed at the end is more difficult for the athletes to execute.
