Background: Moderate altitudes carry physiological and metabolic
changes that can dampen exercise performance. Fortunately, these
changes can be modulated by an optimal nutritional intervention.
This case study represents the first nutritional intervention of
a moderate altitude athlete. These results may help to establish
well-designed nutritional guidelines for moderate altitude sports
athletes.
Case presentation: This case study examined the effects of a 11-
week nutritional intervention on body composition, muscle
strength, cardiorespiratory fitness, resting and exercise nutrient
oxidation, and subjective sleep quality, in a male high-level moderate
altitude athlete with a very light non-exercise activity thermogenesis.
During the 11-week of nutritional intervention, 2800-3500
kcal/day, 6.8-8.9 g/kg/day of carbohydrates, 1.2-1.7 g/kg/day of
protein, and 1-2.5 g/kg/day of fat were prescribed. Different specific
considerations were also included, such as: iron supplementation,
antioxidants increment in different phases, and ergogenic aids (i.e.
creatine and beta-alanine). Our results demonstrated a decrease in
adiposity and an increase in fat-free mass. In parallel, the athlete
improved muscle strength, and therefore endurance adaptations
after a maximal effort test (i.e. enhancement of the heart rate
recovery). After the intervention, the athlete not only increased
the carbohydrate oxidation during exercise and resting conditions
but also improved his subjective sleep quality.
Conclusions: Our results suggest that a nutritional intervention
based on the endurance nutritional recommendations and adapted
to the altitude physiological peculiarities can induce body recomposition,
improve physiological adaptations to effort, and
upgrade the substrate oxidation in a moderate altitude high-level
athletes.
