Abstract:

The body fat percentage and muscle mass were measured in 6687 samples from 15 populations in the Northwest Ethnic Corridor using the bioelectrical resistance method. It has been found that the degree of obesity has little effect on grip strength, heart rate, and postprandial blood glucose in the Northwest Ethnic Corridor population,which would lead to the increase of hypertension rate, decrease of blood oxygen saturation and lung capacity, promote the increase of fasting blood glucose and increase the incidence of diabetes. Correlation analysis showed that muscle mass was significantly and positively correlated with systolic and diastolic blood pressure in males. In females, muscle mass was not significantly correlated with systolic blood pressure and was significantly positively correlated with diastolic blood pressure. Muscle mass had no significant effect on fasting blood glucose and postprandial blood glucose. Body fat percentage was significantly and positively correlated with systolic and diastolic blood pressure in males and females, and significantly and negatively correlated with oxygen saturation and lung capacity. Muscle mass was significantly positively correlated with both grip strength and lung capacity. A two-way ANOVA showed that there was a main effect of body fat percentage and muscle mass on the effect of blood pressure, and no interaction effect of the two on the effect of blood pressure. The results of the study suggest that the formation and evolution of populations can have a significant impact on the values of physiological indicators.

Key words: body fat percentage, muscle mass, blood pressure, blood glucose, population evolution
