論文Effects of Trehalose Solutions at Different Concentrations on High-Intensity Intermittent Exercise Performance査読有その他国内共著Naomi Hamada, Tsuyoshi Wadazumi, Yoko Hirata, Hitoshi Watanabe, Nobuko Hongu, Norie AraiNutrients2022, 14(9), 17762022年4月 23日Trehalose solution ingested during exercise induces gradual increases in blood glucose levels and the insulin response compared with glucose solution. Trehalose solution aids in the maintenance of performance in the later stages of prolonged exercise. The purpose of this study was to identify the lowest concentration at which the properties of trehalose could be exploited. Groups of 12 healthy men (21.3 ± 1.3 years) and 10 healthy men (21.1 ± 0.7 years) with recreational training were included in experiments 1 and 2, respectively. Both experiments followed the same protocol. After fasting for 12 h, the participants performed a 60 min constant-load exercise at 40% V˙O2 peak using a bicycle ergometer and ingested 500 mL of a trial drink (experiment 1: water, 8% glucose, and 6 or 8% trehalose; experiment 2: 4 or 6% trehalose). They performed four sets of the Wingate test combined with a 30 min constant-load exercise at 40% V˙O2 peak. The experiment was conducted using a randomized cross-over design; trial drink experiments were conducted over intervals of 7 to 12 days. The exercise performance was evaluated based on mean power in the Wingate test. Blood was collected from the fingertip at 12 points during each experiment to measure blood glucose levels. During the high-intensity 5 h intermittent exercise, no differences were found between the groups in exercise performance in the later stages with concentrations of 8, 6, and 4% trehalose solution. The results suggest that trehalose could be useful for making a new type of mixed carbohydrate solution. Further studies to determine the trehalose response of individual athletes during endurance exercise are needed.
論文Carbohydrate Mouth Rinse and Spray Improve Prolonged Exercise Performance in Recreationally Trained Male College Students査読有その他国内共著Asako Shirai;Tsuyoshi Wadazumi;Yoko Hirata;Naomi Hamada;Nobuko Hongucarbohydrate mouth rinseSportsSports 2022, 10(4), 512022年3月 29日～2022年3月 29日https://doi.org/10.3390/sports10040051Mouth rinsing with a carbohydrate (CHO) solution has emerged as a sports nutrition strategy to increase endurance performance. This study aimed to clarify the effects of two forms of CHO sensing in the mouth (i.e., CHO mouth rinse (CMR) and CHO mouth spray (CMS)) on exercise performance during prolonged exercise, including ultra-high intensity intermittent exercise over time. We conducted the following experimental trials: (1) 6% glucose solution (G), (2) 6% CMR, (3) 6% CMS, and (4) water (WAT). These trials were conducted at least 1 week apart in a randomized crossover design. Eight male college students performed constant-load exercise for 60 min (intensity 40% VO2peak), four sets of the Wingate test (three 30 s Wingate tests with a 4 min recovery between each test), and a constant-load exercise for 30 min (intensity 40% VO2peak). The mean exercise power output (Watt), ratings of perceived exertion, and blood glucose levels were measured. We found that the mean power values of the CMR and CMS in the third and fourth sets was significantly higher than that of WAT (p < 0.05), and that the G trial did not show a significant difference from any other trial. Thus, when compared to G or WAT, CMR and CMS can help improve endurance exercise performance.
論文Effect of Paprika Xanthophyll Supplementation on Cognitive Improvement in a Multitasking Exercise: A Pilot Study for Middle-Aged and Older Adults査読有その他国内共著Asako Shirai;Tsuyoshi Wadazumisupplementation; cognitive function; multitasking exercise; xanthophyll; erythrocyte deformability; oxygen transport efficiencyHealthcare2022, 10(1), 812022年1月 1日Ingestion of paprika xanthophyll supplement (PX), which has antioxidant effects, has been recently reported to maintain red blood cell deformability and improve oxygen delivery efficiency. Therefore, we hypothesized that the brain activation induced by multitasking exercise in middle-aged and older participants along with the improved erythrocyte oxygen-carrying efficiency induced by PX supplementation would show a synergistic effect, increasing oxygen supply to the brain and improving cognitive function more effectively. In study 1, cerebral blood flow measurements were conducted during the multitasking exercise and cognitive function tests to verify their effect on cognitive function. The results confirmed that cerebral blood flow increased during the exercise and cognitive function improved after the exercise. In study 2, we compared the effects of the multitasking exercise on cognitive function before and after PX supplementation in middle-aged and older participants to evaluate the effects of PX supplementation. The results suggested that PX supplementation enhanced the effects of active multitasking exercise on cognitive function. We speculate that the improvement of oxygen transport efficiency by PX resulted in more effective oxygen supply, allowing the multitasking exercise to occur more effectively, which was reflected as an improvement in the cognitive function.
論文炭水化物マウスリンスが等尺性掌握運動パフォーマンスに及ぼす影響査読有学術雑誌国内共著平田 庸子, 弘原海 剛, 濱田 尚美, 白井 麻子, 渡辺 一志体力科学2021 年 70 巻 4 号 p. 269-2762021年8月 https://doi.org/10.7600/jspfsm.70.269 本研究の目的は，マウスリンスの効果特性について明らかにするため，等尺性掌握運動を用いて，疲労耐性の違いによるマウスリンス効果について検討した．その結果，疲労耐性が低い L 群においてマウスリンスによるMVCの低下抑制が確認された．このことにより，マウスリンスには，運動性疲労の低下を抑制する効果特性があることが明らかとなった．加えて，マウスリンス効果には炭水化物の持つ甘味による影響も含まれる可能性が示唆された．
論文Single Ingestion of Trehalose Enhances Prolonged Exercise Performance by Effective Use of Glucose and Lipid in Healthy Men査読有その他国内共著Naomi Hamada;Tsuyoshi Wadazumi;Yoko Hirata;Mayumi Kuriyama;Kanji Watanabe;Hitoshi Watanabe;Nobuko Hongu;Norie AraiNutrients2021, 13(5), 1439; https://doi.org/10.3390/nu130514392021年4月 24日A single ingestion of trehalose helped to maintain prolonged exercise performance.
論文Effects of a Single Ingestion of Trehalose during Prolonged Exercise査読有その他国際共著WADAZUMI,TsuyoshiSports — Open Access JournalSports 2019, 7(5), 100; https://www.mdpi.com/2075-4663/7/5/1002019年4月 29日The aim of this study was twofold. First, we examined exercise performance following ingestions of either GLU, TRE, or water (WAT). The second purpose was to investigate the effects of TRE energy metabolism during prolonged exercise.
In conclusion, we provide novel data that a single TRE ingestion was effective in improving prolonged exercise performance by effective use of glucose and lipids.
