| Outline of Final Research Achievements |
The purpose of this study was to examine the feasibility of calculating short-term total energy expenditure (TEE) using the doubly labeled water (DLW) method. TEE was determined at 6 and 12 hours, and at 1, 5, and 7 days, in healthy adults. At 6 and 12 hours, some subjects showed negative TEE values, thus making the values unreliable. At 1 day, although the unevenness of the TEE value was reduced, the physical activity level (PAL) of some subjects exceeded the theoretical values. Furthermore, in endurance athletes, the short-term TEE was determined during normal training and tapering training. Similarly, repetition analysis showed that for periods of less than 1 day, TEE values appeared to be uneven, and to vary among the subjects. However, the average TEE values at 2 days were similar to those at 7 days, including days of rest from training. These results indicate that inventions for increasing the measurement accuracy for short-term TEE calculation may be feasible.
