A mountaineering expedition is not limited to the strenuous ascent but also to the accompanying climatic conditions. Together, these factors influence the increased energy demand during the trip. Proper nutrition planning is crucial to derive not only satisfaction but also health benefits from the mountain hike. Therefore, it is advisable to carefully consider which foods to bring when preparing provisions, in order to ensure a sufficient amount of energy and nutrients.
Is that truly the reason that mountains necessitate a higher amount of energy?
In mountainous conditions, therefore, greater exertion is required to maintain the body's homeostasis, which is the balance necessary to maintain a balance of all physiological processes. The higher our route is above sea level, the lower the oxygen availability in the air, and the greater the increase in hypoxia. In addition to the altitude of the body, the additional challenge is the exposure to specific climatic conditions such as temperature, precipitation, and humidity. The largest portion of energy is dedicated to maintaining the body's basic functions and sustaining a stable body temperature. This last task becomes a significant challenge in colder climates. Heat dissipation is a crucial factor in maintaining the homeostasis of the entire organism. The height of 3000 meters above sea level results in an increase in basal metabolic rate, and the organism can then use up to 25% more energy than during activities in lowlands. In mountainous conditions, the caloric requirement is amplified by unfavorable weather conditions. During physical exertion in low temperatures, the organism must work hard to achieve the same intensity - it therefore requires more energy.
