title: Anthropometric and health-related fitness characteristics in middle-aged obese women.
abstract: The purpose of this investigation was to determine the possible relationships between anthropometrical and health-related fitness parameters in obese middle-aged women. Twenty one obese (BMI > 27 kg/m2) and 12 control (BMI < 27 kg/m2) middle-aged females (35-45 yrs) participated in this investigation. Three series of anthropometrical measurements on the right side of the body were taken according to the O-scale physique assessment system. The Heath-Carter anthropometric somatotyping method was used and the ratio of waist to hip circumferences was calculated. The body composition was measured using bioelectrical impedance method (Bodystat-500, UK). The following health-related fitness tests used were: dynamic sit-up, hand grip, sit-and-reach, single leg balance and plate tapping. Physical working capacity (PWC) was measured using single ergometer test. Obese women possessed significantly higher (p < 0.05) values for skinfold, girth and breadth measurements. While the differences in somatotype indices were not statistically significant (p > 0.05) between obese and control groups, the transformation of somatotype characteristics to the effect sizes (ESs) revealed that these differences were large (ectomorphy: ES = 1.73; endomorphy: ES = 1.64; mesomorphy: ES = 1.71). Relative aerobic fitness (VO2max/kg, calculated from PWC) and dynamic sit-up were higher (p < 0.05) in control subjects, while obese women presented significantly higher values for hand grip strength. The thicker skinfold thicknesses increased the absolute value of PWC in obese group (r = 0.39-0.57; p < 0.05). In contrast, the thinner skinfold thicknesses in suprailiac and mid-thigh significantly increased the absolute value of PWC in control women. There were only a few significant correlations between girth and breadth measures, and health-related fitness parameters. In addition, somatotype characteristics seldom influenced the results of health-related fitness tests. Stepwise multiple regression analysis demonstrated that health-related fitness test items were more dependent on the anthropometrical parameters in obese than in control women.
