     View Summary

    Athletes experience high total energy expenditure; therefore, it is important to understand the characteristics of the components contributing to this expenditure. To date, few studies have examined particularly the volume and activity intensity of non-exercise activity thermogenesis (NEAT) in athletes compared to non-athletes under real-life conditions. This study aimed to determine the volume and intensity of NEAT in collegiate athletes. Highly trained Japanese male collegiate athletes (n = 21) and healthy sedentary male students (n = 12) participated in this study. All measurements were obtained during the athletes' regular training season under real-life conditions. NEAT was calculated using metabolic equivalent (MET) data using an accelerometer. The participants were asked to wear a validated triaxial accelerometer for 7 consecutive days. Physical activity intensity in NEAT was classified into sedentary (1.0–1.5 METs), light (1.6–2.9 METs), moderate (3.0–5.9 METs), and vigorous (≥6 METs) intensity. NEAT was significantly higher in athletes than in non-athletes (821 ± 185 kcal/day vs. 643 ± 164 kcal/day, p = 0.009). Although there was no significant difference in NEAT values relative to body weight (BW) between the groups (athletes: 10.5 ± 1.7 kcal/kg BW/day, non-athletes: 10.4 ± 2.2 kcal/kg BW/day, p = 0.939), NEAT to BW per hour was significantly higher in athletes than in non-athletes (0.81 ± 0.16 kcal/kg BW/h vs. 0.66 ± 0.12 kcal/kg BW/h, p = 0.013). Athletes spent less time in sedentary and light-intensity activities and more time in vigorous-intensity activities than non-athletes (p < 0.001, p = 0.019, and p = 0.030, respectively). Athletes expended more energy on vigorous- and moderate-intensity activities than non-athletes (p = 0.009 and p = 0.011, respectively). This study suggests that athletes' NEAT relative to BW per day is similar to that of non-athletes, but athletes spend less time on NEAT, which makes them more active in their daily lives when not exercising and sleeping.

  • Resting energy expenditure is lower in Japanese female athletes with menstrual disorders than in eumenorrheic athletes

     View Summary

    Menstrual disorders are health problems in female athletes. It has also been reported that amenorrhea can lead to metabolic suppression. However, studies regarding resting energy expenditure (REE) in Japanese female athletes with menstrual disorders are lacking. The purpose of this study was to investigate whether REE was suppressed in female Japanese athletes with menstrual disorders. In total, 22 highly trained intercollegiate athletes participated in this study; and body composition, REE, thyroid and reproductive hormone levels, and nutritional intake levels were measured. Predicted REE (REEp) was calculated using two different equations based on fat-free mass (FFM) and organ-tissue mass measured by dual-energy X-ray absorptiometry (DXA). Individuals with menstrual disorders (MD group) had significantly lower height, body weight, and fat mass than those in the eumenorrheic (EU) group; however, the FFM did not differ between the groups. Both the measured REE (REEm) and REEm adjusted for FFM in the MD group were lower than those in the EU group. The REEm to REEp ratio, which indicates energy deficiency, was also lower in the MD group. In addition, although the MD group had lower triiodothyronine and progesterone levels, they were still within the normal range. Japanese female athletes with menstrual disorders may have lower REE than eumenorrheic athletes, even if thyroid and reproductive hormones are within the normal range.

  • 大学生競技者の低エネルギー問題解決に向けた栄養指導の効果

    2022   田口 素子

     View Summary

     本研究の目的は、競技者を対象にエネルギー不足の改善を目的とした栄養指導介入がエネルギー代謝及び血液生化学指標に及ぼす効果を明らかにすることであった。 女性競技者6名を本研究の対象とした。スクリーニング時にはすべての対象者のenergy availability (EA) が低い状態にあり、かつすべての対象者がエネルギー不足を起因とする健康問題を1つ以上有していた。その後、対象者に栄養指導介入を実施した。介入前後に身体組成、EA、安静時代謝量及び血液生化学指標を測定・評価した。介入後測定は終了しており、今後は得られたデータの解析を進め、栄養指導の効果について明らかにする予定である。

  • 競技者の増量食の摂取は食事誘発性熱産生を増大させるか?

    2022   田口 素子

     View Summary

     本研究の目的は、競技者の増量食の摂取が食事誘発性熱産生 (diet induced thermogenesis: DIT) を増大させるかどうかを検討することであった。 本年度は被験者の選定とプロトコールの検討を行った後、男子大学生競技者と一般男子大学生 (非競技者) を対象としDITを測定した。ダグラスバッグ法を用いて安静時の代謝量を測定した後、600 kcalの液体食を摂取させ、食後3時間のDITを測定した。その結果、競技者と非競技者の食後3時間のDITに統計的な有意差は認められなかった。今後はデータの解析を進め、本研究で得られた研究成果は論文としてまとめて学術雑誌へ投稿する予定である。
