Outline of Final Research Achievements

In this study, we examined the combination effects of providing high animal protein foods (20 g of protein/day) and exercise on body composition and physical function in the elderly person cared. Providing high animal protein foods significantly increased the estimated animal protein intake evaluated by the brief self-administered diet history questionnaire, compared to that of before intervention. The muscle mass and grip strength (right hand) were significantly increased and the body fat percentage was significantly decreased, following increased high animal protein foods intake plus exercise once or twice a week (180 min each time) for 3 months, compared to that before intervention. However, 3-months after interruption of food intervention, muscle mass was significantly lower than that after food intake plus exercise intervention. There was a significant positive correlation between the changes of muscle mass and estimated dairy products intakes increased by food intervention.

Academic Significance and Societal Importance of the Research Achievements

たんぱく質平均20g/日分の食品の提供および週1に2回のリハビリセンター（デイサービス）内で行われている筋力運動教室への参加の3ヶ月間と食事提供をやめた3ヶ月間を比較したところ、食事＋運動介入した期間で要支援・要介護高齢者の筋肉量および握力（右手）が増加し、運動のみ介入後には筋肉量の低下が見られた。高たんぱく質含有加工食品等の提供および運動負荷を組み合わせることで要支援・要介護高齢者の筋肉量の増加が認められ、フレイルを予防できることが示唆された。これらの結果を広く汎用すべくICTを活用したプログラムの開発が高齢者の自立支援に貢献できると考える。
