Effects of resistance training frequency on body composition and metabolics and inflammatory markers in overweight postmenopausal women.

The present study aimed to determine the importance of resistance training frequency on body composition and metabolics and inflammatory markers in sedentary overweight postmenopausal women (PW). Thirty subjects finished the resistance training-protocol (60% to 80% of 1-RM) and had all the evaluations (anthropometry, strength, food intake and biochemistry) done. Groups were assembled according to the week-frequency of attended sessions (G1-1 day/wk, N.=9; G2-2 days/wk, N.=11 and G3-3 days/wk, N.=10). The strength-training protocol resulted in similar changes on body composition and strength gains in all groups. However, the plasma markers responses differed among groups with G1 showing an increase of both CRP and glucose, with G2 increasing CRP and G3 keeping the baseline values. The results suggest that resistance exercise increases strength and muscle mass independently of the frequency. Moreover, highest resistance training frequency (3 days/week) prevented the rise of plasma glucose and CRP profile after 16 weeks of training in sedentary overweight PW.

Accuracy of sagittal abdominal diameter as predictor of abdominal fat among Brazilian adults: a comparation with waist circumference.

AIM: We aim was to compare the sagittal abdominal diameter (SAD) with waist circumference (WC) as a predictor of central obesity among adults and to identify the sensitivity and specificity of the best cut-off point for SAD. METHODS: A cross-sectional study of 266 Brazilians adults (euthrophic and overweight), aged 31-84 years old, of which 89 men and 177 women, was carried out. Anthropometric measurements such as SAD, weight, height, waist and hip circumferences, waist and hip ratio, body mass index, body fat percentage were performed. Receiver Operating Characteristics (ROC) curve was used to identify the sensitivity and specificity of the best cut off point for SAD as a predictor of central obesity. Statistical analysis were considered significant with a value of p < 0.05. RESULTS: The SAD measurement was positively correlated with WC for both genders, although stronger among overweight and obesity women (r = 0.71; p < 0.001 and r = 0.79; p < 0.001, respectively) than men. ROC curves identified the best cut-off points for SAD of 23.1 cm and 20.1 cm for men and women (96% and 85% sensitivity, 86% and 84% specificity, respectively). CONCLUSION: SAD measurement may be used as an anthropometric tool to identify central obesity among women for presenting adequate sensitivity and specificity.

Objetivo: Nuestro objetivo es comparar el diámetro abdominal sagital (DAS) con la circunferencia de la cintura (CC) como predictor de la obesidad central entre los adultos y para determinar la sensibilidad y la especificidad de la mejor punto de corte para el DAS. Métodos: Estudio transversal de 266 adultos brasileños (eutróficos y con sobrepeso), de entre 31-84 años de edad, de los cuales 89 hombres y 177 mujeres, se llevó a cabo. Las medidas antropométricas como la DAS, peso, talla, circunferencia de la cintura y cadera, relación cintura-cadera, índice de masa corporal, porcentaje de grasa corporal se llevaron a cabo. Receiver Operating Characteristics (ROC) curva se utilizó para determinar la sensibilidad y la especificidad del mejor punto de corte para el DAS como predictor de la obesidad central. El análisis estadístico se consideró significativo un valor de p < 0,05. Resultados: La medición del DAS se correlacionó positivamente con CC para ambos sexos, aunque más fuerte entre las mujeres con sobrepeso y obesidad (r = 0,71, p < 0,001, r = 0,79, p < 0,001, respectivamente) que los hombres. De curvas ROC identificado las mejores puntos de corte para el DAS de 23.1 cm y 20.1 cm para los hombres y mujeres (96% y el 85% de sensibilidad, 86% y el 84% de especificidad, respectivamente). Conclusión: La medición DAS puede ser utilizada como una herramienta antropométrica para identificar la obesidad central entre las mujeres para la presentación de la sensibilidad y especificidad adecuadas (AU)
