Hematological status and functional abilities of the cardiorespiratory system of physically active female vegans

摘要

The aim of this study was to examine the influence of vegan diet on hematological parameters, and to compare the functional abilities of the cardiorespiratory system of vegans and counterparts on a standard diet. The sample consisted of 24 females, divided into two groups: 11 vegans and 13 women on a standard diet. Assessment of the level of physical activity of the participants was estimated by the standard IPAQ questionnaire. Hematological analysis included: complete blood count, blood lipid profile, vitamin B12 and iron. Basic anthropometric variables were monitored, and a submaximal Astrand test on a bicycle ergometer was used to estimate maximal oxygen consumption. The RAMP continuous protocol was used to measure the maximum values of heart rate and blood pressure. The results showed that active vegans have a significantly lower body weight and body mass index compared to active women on a standard diet. The number of erythrocytes and platelets, as well as LDL - cholesterol show lower values in vegans compared to the control group (p<0.01). Indicators of the functional abilities of the cardiorespiratory system do not differ between active vegans and women on a standard diet.
