Abstract

Abstract Accurate quantification of energy intake is imperative in athletes; however traditional dietary assessment tools are frequently inaccurate. Therefore, this study investigated the validity of a contemporary dietary assessment tool or wearable technology to determine the total energy intake (TEI) of professional young athletes. The TEI of eight professional young male rugby league players was determined by three methods; Snap-N-Send, SenseWear Armbands (SWA) combined with metabolic power and doubly labelled water (DLW; intake-balance method; criterion) across a combined ten-day pre-season and seven-day in-season period. Changes in fasted body mass were recorded, alongside changes in body composition via isotopic dilution and a validated energy density equation. Energy intake was calculated via the intake-balance method. Snap-N-Send non-significantly over-reported pre-season and in-season energy intake by 0.21 (2.37) MJ.day−1 (p = 0.833) and 0.51 (1.73) MJ.day−1 (p = 0.464), respectively. This represented a trivial and small standardised mean bias, and very large and large typical error. SenseWear Armbands and metabolic power significantly under-reported pre-season and in-season TEI by 3.51 (2.42) MJ.day−1 (p = 0.017) and 2.18 (1.85) MJ.day−1 (p = 0.021), respectively. This represents a large and moderate standardised mean bias, and very large and very large typical error. There was a most likely larger daily error reported by SWA and metabolic power than Snap-N-Send across pre-season (3.30 (2.45) MJ.day−1; ES = 1.26 ± 0.68; p = 0.014) and in-season periods (1.67 (2.00) MJ.day−1; ES = 1.27 ± 0.70; p = 0.012). This study demonstrates the enhanced validity of Snap-N-Send for assessing athlete TEI over combined wearable technology, although caution is required when determining the individual TEIs of athletes via Snap-N-Send.

当代饮食评估工具或可穿戴技术能否准确评估职业橄榄球联盟年轻球员的能量摄入?双标签水验证研究

准确量化运动员的能量摄入是十分必要的;然而，传统的饮食评估工具往往是不准确的。因此，本研究探讨了当代膳食评估工具或可穿戴技术在确定专业青年运动员总能量摄入(TEI)方面的有效性。采用三种方法测定了8名职业橄榄球联盟青年男运动员的TEI;Snap-N-Send, SenseWear臂带(SWA)结合代谢能力和双标签水(DLW;intake-balance方法;标准)在10天的季前赛和7天的季前赛期间。通过同位素稀释和经过验证的能量密度方程，记录了禁食体重的变化，以及身体成分的变化。能量摄入通过摄入平衡法计算。Snap-N-Send不显著超额报告季前和季中能量摄入0.21 (2.37)MJ。day−1 (p = 0.833)和0.51 (1.73)MJ。Day−1 (p = 0.464)。这代表了一个微不足道的小标准化平均偏差，和非常大的典型误差。SenseWear Armbands和代谢能力显著低于季前和季中TEI 3.51 (2.42) MJ。day−1 (p = 0.017)和2.18 (1.85)MJ。Day−1 (p = 0.021)。这代表了一个大的和中等的标准化平均偏差，以及非常大和非常大的典型误差。在季前赛中，SWA和代谢能力报告的日误差很可能比Snap-N-Send更大(3.30 (2.45)MJ.day−1;es = 1.26±0.68;p = 0.014)和旺季(1.67 (2.00));es = 1.27±0.70;p = 0.012)。这项研究证明了Snap-N-Send在评估运动员TEI方面比联合可穿戴技术更有效，尽管在通过Snap-N-Send确定运动员的个人TEI时需要谨慎。
