Get PDF本研究は，大学男子サッカー選手における日常トレーニング後の体内水和状態を２種類の非侵襲的メソッドを用いて検討することを目的とした。被検者は，環太平洋大学体育会に所属する男子サッカー部員15名であった（age: 19.5±1.4 year, height: 173.2±5.9 cm; body weight: 67.0±7.6 kg; BMI: 22.6±1.8 kg/m2, body fat: 11.6±3.6 %）。サッカートレーニングはボールハンドリング，シューティング，その他の技術練習及びゲームから構成された。それらの練習は，約３時間に及んだ。サッカートレーニング前後で，脱水症状の指標となる尿比重値と尿浸透圧値を測定した。二元配置分散分析により，サッカートレーニング後で，尿比重値及び尿浸透圧値は有意に増加することが判明したが，練習日間による差はみられなかった。また，尿比重値と尿浸透圧値との間に，有意な相関が認められた。これらの結果から，尿比重値だけでなく尿浸透圧値も間欠的運動が長時間続くサッカーのようなトレーニング形態で，体内水和状態を評価する指標として応用することが可能であることが示唆された。The purpose of this study was to determine the effects of habitual soccer training on hydration status in male collegiate players based on two types of non-invasive methods. Fifteen male collegiate soccer players (age: 19.5±1.4 year, height: 173.2±5.9 cm; body weight: 67.0±7.6 kg; BMI: 22.6± 1.8 kg/m2, body fat: 11.6±3.6 %) served as the subjects. The soccer training consisted of routine ball handling, shooting, other specialized skill training and games. Spot urine was collected within 10 minutes before (Pre) and after (Post) each training session over three consecutive days (Day 1, Day 3, and Day 5). For analysis of hydration status, urine specific gravity (Usg) and osmolality (Uosm) were determined with a handheld refractometer and osmometer, respectively. Each training session lasted approximately 3 hours. A two-way analysis of variances (ANOVA) showed significant main effects for time before and after the soccer training session, but no difference across days in Usg (g/mL) or Uosm (mOsm/kg H2O). Moreover, linear regression analysis of the present data demonstrated a significant correlation between Usg and Uosm. These findings indicate that noninvasive measurements of Uosm as well as Usg could be applicable to the field settings with regard to hydration status over three consecutive days of soccer training
