N2  - Heart rate alveolar gas partial pressures and blood lactate (BLa) concentration were measured during synchronized swimming in six subjects. During upside-down breath-holding lasting 50 s, heart rate fell progressively from 98+/-14 to 70+/-7 beats/min (X+/-S.D.). While breath-holding during the compulsory figures, the subjects heart rate increased to 142+/-5 beats/min and then fell to 72+/-10 beats/min. At the end of breath-holding, alveolar oxygen pressure had fallen significantly (60 mmHg), whereas alveolar carbon dioxide pressure showed only minor changes (48 mmHg). The increase in BLa concentration due to the execution of compulsory figures was approximately 1 mM; in the free routines, BLa concentration increased by 3.4+/-0.5 mM. The net energy cost of completing a compulsory figure lasting 45 s was 34.6 kJ. Verf.-Referat
