Abstract

AIRES FERREIRA, Sandra et al. Association between relative muscle strength and indicators of obesity in university professors. Cienc Trab. [online]. 2018, vol.20, n.61, pp.31-35. ISSN 0718-2449.  http://dx.doi.org/10.4067/S0718-24492018000100031.

The aim of the study was to verify the association between relative muscular strength and indicators of obesity in university professors. 71 teachers (37 men and 34 women) were submitted to measurement of waist circumference (WC) and the handgrip test. Based on body mass (BM) and height was calculated Body Mass Index (BMI). Relative muscle strength (% FM) was determined by ratio of the averaged val ues of right and left handgrip by MC. Based on the values of the % FM, the sample was stratified into tertiles according to gender for comparison of MC, BMI and WC using the Kruskal-Wallis test; to identify the difference between two groups was used the Mann- Whitney test and for correlation was used the Spearman coefficient. Men of the 3rd tertile showed lower values significantly on indicators of obesity when compared to the 1st and 2nd tertile. There was no difference for women in obesity indicators, although the values found were lower with increasing level strength. The inverse correlations were observed for MC, BMI and WC in both genders. The performance of strength palmar prehension suggests higher importance in the pre vention of obesity between men than women professors.
