Outline of Final Research Achievements

Insufficient energy and nutrient intake can lead to serious accidents while mountain climbing. Therefore, we evaluated a meal for mountaineers to reduce such accidents. A fact-finding survey revealed that most mountaineers bring rice balls or sweet bread with them when mountain climbing. This meal costs 300 to 400 yen and weighs less than 500 g. We also studied the effects of diet on physiological responses and found that the consumption of rice balls or sweet bread alone led to a rapid increase in skin temperature, heart rate, and blood glucose levels during exercise compared to a diet consisting of a staple meal, main dish, and side dishes. Based on these findings, we proposed a recipe for a meal for mountaineers that is nutritious, lightweight, and easily preserved. We found that consumption of our proposed meal maintained blood glucose levels during walking and reduced concentration difficulties and fatigue

Academic Significance and Societal Importance of the Research Achievements

毎年，滑落や道迷いによる遭難者は3,000人前後と，増加傾向にある。これらの要因として，エネルギーや栄養素の摂取不足による集中力や思考力の低下が考えられる。本研究では，登山者が多く持参するおにぎりやパン単体を摂取した際の生理応答から，それらの食事の問題点を明らかにした。次にこれらを踏まえ，保存性，重量，嗜好性などを考慮した登山食を提案し，これらが登山中の血糖値の維持や集中力，疲労感の軽減につながる可能性を示した。本研究で得られた知見は，重大な登山事故予防に寄与すると考えられる。
