“…The present study reports a PAL for wrestlers of 2.5860.34, 2.4760.42 and 2.7360.06 (mean, light and middle weight class, respectively) during a training period. This is higher than that reported for Japanese adolescents in general (1.9760.31 in subjects who exercised, and 1.8560.27 in subjects who did not exercise) (36). This result suggests that the physical activity of collegiate wrestlers during the winter training season is classified as high physical activity when it is compared with previous studies (30).…”

SummaryEstimated energy requirements (EERs) are important for sports based on body weight classifications to aid in weight management. The basis for establishing EERs varies and includes self-reported energy intake (EI), predicted energy expenditure, and measured daily energy expenditure. Currently, however, no studies have been performed with male wrestlers using the highly accurate and precise doubly labeled water (DLW) method to estimate energy and fluid requirement. The primary aim of this study was to compare total energy expenditure (TEE), self-reported EI, and the difference in collegiate wrestlers during a normal training period using the DLW method. The secondary aims were to measure the water turnover and the physical activity level (PAL) of the athletes, and to examine the accuracy of two currently used equations to predict EER. Ten healthy males (age, 20.460.5 y) belonging to the East-Japan college league participated in this study. TEE was measured using the DLW method, and EI was assessed with self-reported dietary records for ~1 wk. There was a significant difference between TEE (17.962. . The measured PAL (2.660.3) was higher than two predicted values during the training season and thus the two EER prediction equations produced underestimated values relative to DLW. We found that previous EERs were underestimating requirements in collegiate wrestlers and that those estimates should be revised. Key Words doubly labeled water, wrestler, total energy expenditure, energy intake, water turnoverThe sport of wrestling is an individual combat Olympic sport that is practiced all over the world. It is a weight-class sport and as elite athletes are involved in daily training and competition, it is essential to determine their energy and water requirements to aid in maintaining optimal weight (1-4). Other sports based on body-weight classification similar to wrestling, such as judo and boxing, also need accurate measures of requirements to establish an energy-and-water-intake plan to accomplish athletes' target body weight for matches (5-8). The doubly labeled water (DLW) method has been proposed as a criterion method to estimate energy requirement (EER) because it is an accurate and objective method for measuring total energy expenditure (TEE) and water turnover for field athlete studies in free-living conditions with minimum constraints (9, 10). Because of its lower cost, self-reported energy intake (EI) has been commonly used to estimate EER for athletes; however, the self-reported EI measurement has been shown to underestimate EI compared with measured TEE (11). For example, among non-athletes, comparison of self-reported EI with DLW-derived TEE demonstrated that over one-third of individuals underreport EI by more than 25% when using the DLW method in several different population groups (12). The underestimation of EI has also been found in athletes, and the range of error has been reported to be between 0 and 243% (13). Errors in this range plague EI planning for some athletes, because an inadequate ...

“…Therefore, the underrepresentation of developing countries and the lack of published results from Asia has to be underlined. Although there are several studies in the literature on PA evaluated with accelerometry in Asian children and adolescents, these studies employed different accelerometers (e.g., [84,85]) and/or different cutoff points (e.g., [84][85][86]).…”

Associations of Physical Activity and Sedentary Behaviour Assessed by Accelerometer with Body Composition among Children and Adolescents: A Scoping Review

The possible adverse health effects of reduced physical activity (PA) on children and adolescents have been extensively documented as a result of the global obesity epidemic. However, the research has sometimes led to controversial results, due to the different methods used for the assessment of PA. The main aim of this review was to evaluate the association between PA and body composition parameters based on quantitative PA studies using the same equipment (Actigraph accelerometer) and cutoffs (Evenson’s). A literature review was undertaken using PUBMED and Scopus databases. Subjects aged 6–15 were considered separately by sex. Weighted multiple regression analyses were conducted. From the analysis of fourteen selected articles, it emerged that 35.7% did not evaluate the association of sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) with body composition, while the remaining 64.3% found a negative association of MVPA with BMI and fat mass with different trends according to sex. Furthermore, only 7.1% of these studies identified a positive association between ST and fat percentage. Based on the regression analyses conducted on the literature data, ST and MVPA were found to be significant predictors of body composition parameters, in addition to age and sex. Further studies using standardized methodologies to assess PA and body composition are needed. The inclusion of sex-disaggregated data may also be crucial to understand this phenomenon and to provide stronger evidence of the determinants of body composition in order to prevent the risk of obesity.

“…Doubly labeled water (DLW) is the most accurate TEE estimation method under free-living conditions [ 6 , 7 ], but it is expensive and requires specialized analysis equipment [ 8 ], making large-scale data collection difficult. The Japan-DRI refers to only 2 reports of DLW data from Japanese children [ 9 , 10 ]. Consequently, the EER of Japanese children is determined based on other nationalities.…”

BackgroundTo establish Japanese children’s estimated energy requirements, total energy expenditure (TEE) data measured using the doubly labeled water (DLW) method is needed. This study aimed to 1) obtain basic TEE data from Japanese children measured using DLW (TEEDLW), 2) compare TEEDLW with TEE estimated by various estimation formulas to calculate their accuracy, and 3) develop a new equation to estimate TEE using body composition and pedometers.MethodsTEE was measured using DLW in 56 10- to 12-year-old Japanese children (33 boys, 23 girls). Physical activity level (PAL) was calculated by dividing TEEDLW by estimated resting energy expenditure. To assess their physical activity, participants wore pedometers during the 7-d DLW period. Total body water was calculated from 2H and 18O; fat-free mass (FFM) and fat mass (FM) were then determined.ResultsIn boys and girls of normal weight, TEEDLW was 2067 ± 230 kcal/d and 1830 ± 262 kcal/d, respectively. Average PAL was 1.58 ± 0.17. FFM was strongly related to TEE (r = 0.702, p < 0.01). After adjusting for FFM and FM, step count was significantly associated with TEE (r = 0.707, p < 0.01). The TEE estimation formula used in the Dietary Reference Intakes (DRI) for the United States and Canada estimated TEEDLW with high accuracy (bias: 2.0%) in both sexes. We developed new equations for TEE consisting of FFM and step count, which accounted for 68% and 65% of TEE variance in boys and girls, respectively: boys, 47.1 × FFM (kg) + 0.0568 × step count (steps/d) – 122, and girls, 55.5 × FFM (kg) + 0.0315 × step count (steps/d) - 117.ConclusionsThe TEE in 10- to 12-year-old Japanese children measured using DLW was approximately 7% lower for boys and 12% lower for girls compared to the current Japanese DRI. If PAL can be accurately determined, the equation in the DRI for the United States and Canada may be applicable to Japanese children. In addition, TEE could be predicted using FFM and step count.
