Class development that encourages "awareness" of the perspective of coexistence in dance classes at the teacher training stage

Water balance and energy expenditure in top-level Japanese college female naginata athletes during training
Get PDFDue to various factors, water balance may vary across seasons. These effects may be particularly prominent in athletes and depend on energy expenditure during training. This study assessed water balance by season for a group of top-level Japanese college female naginata athletes during training. Seven top-level Japanese college female naginata athletes were also evaluated for water balance during their training sessions. Participants were observed over three days for each of their seasons of training, i.e., in spring, summer, and winter, with energy expenditure monitored using the heart rate method. Data regarding the total amount of sweat, sweat rate, amount of water intake, and water intake rate were collected for each season, and the differences were assessed using one-way ANOVA. Seasonal differences were calculated using the amount of sweat and water intake per energy expenditure.
The amount of sweat and sweat rate showed high values in summer, and significant differences were observed between each season (p<0.05). A seasonal difference in the amount of water intake and intake rate was also recorded, with high values being shown only in summer (p<0.05). A seasonal difference in the amount of dehydration and dehydration rate was also recorded, with low values only in winter (p<0.05). No seasonal differences in energy expenditure were evident. Results also indicated that the amount of sweat per energy expenditure showed the highest value in summer, followed by spring and then winter, with a significant difference between all seasons (p<0.05). The amount of water intake per energy expenditure differed by season, showing high values in summer (p<0.05). The rehydration rate during training was calculated as 39% in spring, 56% in summer, and 43% in winter.
This study's results suggest that for top-level Japanese college female naginata athletes to maintain water balance, increased water intake is essential during training in summer. Moreover, sufficient hydration is necessary posttraining in spring, summer, and winter.原著論文departmental bulletin pape
