The purpose of this study was to assess the validity of activity record (AR), accelerometer (AC) and heart rate (HR) methods in comparison with the doubly-labeled water (DLW) method as the criterion measure of total energy expenditure (TEE) in high school students undergoing vigorous activities. Twelve baseball players in Japanese high school (16.5±0.5yrs) were monitored for seven consecutive days. TEE values obtained over a 3-day-period by AR, AC and HR were simultaneously validated against TEE measured by DLW over a 7-day-period. TEE value measured by DLW was 4922±391 kcal/day. The Physical activity level (PAL=TEE/BMR (basal metabolic rate)) was 2.66±0.14. TEE estimated by AR, AC and HR was significantly different from DLW, with mean differences of -13.9±6.5%, 35.3±3.6% and 31.6±23.9%, respectively. However, TEE estimated by AC and AR significantly correlated with that measured by DLW (r=0.73, r=0.70, p<0.05, respectively). The limits of agreement between DLW and AR, AC and HR were from -1350kcal/d to -21kcal/d, -2293kcal/d to -1192kcal/d, and 3875kcal/d to -797kcal/d respectively. AC was superior to the other methods. However, the limits of agreement in AR were similar to AC. These data suggest that on accuracy and precision, AR would be superior to the other two for predicting TEE in high school students undergoing vigorous activities. However, AC has the advantages being able to examine patterns of activity over long periods of time without interfering with normal movement and the ability to store data continuously over long periods of time. Therefore, it was suggested that, simultaneously, the AR and AC methods are accurate predictors of TEE and patterns of activity while undergoing sports vigorous activities.
