Analysis of body composition and autonomic function of the heart of schools from northern Mexico by gender

Abstract

Normative values of body composition (CC) and autonomic profile of Mexican schoolchildren are presented. The design corresponds to a study with a quantitative, descriptive approach. The CC was determined using the Poortmans and Slaughter equation, the HRV was in records of short duration. Significant differences were found in muscle mass when comparing: 13.13 ± 3.57kg for women vs 15.79 ± 3.50kg for men with a significance of p = .01. The autonomic profile did not show significant differences, the mean of the mean R-R intervals (MRR) was 616.16 ± 81.52 ms in girls and 611 ± 72.27 ms in boys.
