摘要

耐力运动员越来越多地采用纯素饮食模式,然而研究这种饮食模式对运动相关生理的影响是有限的。因此,本初步研究旨在探讨有氧训练的成年男性在有氧运动中遵循素食和杂食饮食模式的营养状况、饮食质量和心血管和炎症反应。采用渐进式坡道跑步试验评估18-55岁、每周训练>4小时的男性的峰值耗氧量(vo2峰值)。运动测试在步行和稳态跑步条件下进行(vo2峰值的60%和90%)。参与者按饮食模式类型分组,年龄、训练量和最大摄氧量相等。与杂食性组(n = 8,年龄35.6岁,VO2peak 55.7 mL/kg/min)相比,纯素食组(n = 12,年龄33.4岁,VO2peak 56.4 m/kg/min)从碳水化合物中消耗的能量更多(p = 0.007),从蛋白质中消耗的能量更少(p = 0.001),同时表现出更高的整体饮食质量评分(p = 0.008)。在跑步前后,炎症生物标志物没有观察到差异。纯素饮食组的总红细胞计数、血红蛋白和红细胞压积水平较低。总之,经过有氧训练的男性,在长期的纯素饮食之后,与杂食者相比,可以忍受短时间的长距离跑步。应该探索更艰苦的耐力运动条件,以进一步揭示食用纯素饮食模式和运动相关生理的潜在结果。

A comparison of diet quality and cardiovascular and inflammatory responses between aerobically trained male adults following either a long-term vegan or omnivorous dietary pattern.

Vegan dietary patterns are increasingly being adopted by endurance athletes, yet research examining the influence of this dietary pattern on exercise-related physiology is limited. This pilot study, therefore, aimed to explore nutrient status, diet quality and cardiovascular and inflammatory responses in aerobically trained adult males following vegan and omnivorous dietary patterns during aerobic exercise. An incremental ramp running test was used to assess peak oxygen consumption (VO2peak ) in males aged 18-55 years, engaging in >4 h training/week. Exercise testing was performed during walking and steady-state running conditions (60% and 90% of VO2peak ). Participants were grouped by dietary pattern type and were equivalent for age, training volume and VO2peak . When compared to the omnivorous group (n = 8, age 35.6 years, VO2peak 55.7 mL/kg/min), the vegan group (n = 12, age 33.4 years, VO2peak 56.4 m/kg/min) consumed more energy from carbohydrates (p = 0.007), and less energy from protein (p = 0.001) while exhibiting a higher overall diet quality score (p = 0.008). No differences in inflammatory biomarkers were observed before or after running. Total red blood cell count, haemoglobin and haematocrit levels were lower in the vegan dietary group. In summary, aerobically trained males, following a long-term vegan diet, can tolerate a short bout of running broadly comparatively to their omnivore counterparts. More arduous endurance exercise conditions should be explored to further uncover potential outcomes of consuming a vegan dietary pattern and exercise-related physiology.
