Correlation of spirometry with the six-minute walk test in eutrophic and obese individuals.

Objective: To assess the distance covered by both eutrophic individuals and individuals with different grades of obesity and correlate the data obtained with spirometric values. This study is justified by the existing difficulty in assessing the functional capacity in obese individuals, and by the low cost and good specificity of six-minute walk test (6MWT) in predicting reduced capacity for activities of daily living for any individual.

Methods: One hundred fifty-four individuals of both genders were assessed after being divided into two groups: G1, obese individuals (n = 93, BMI ≥ 30 kg/m²) and G2, eutrophic individuals (n = 61, BMI 18.

Correlation of respiratory muscle strength with anthropometric variables of normal-weight and obese women.

Objective: To correlate anthropometric data and respiratory muscle strength (RMS) of normal-weight and obese women.

Methods: The sample consisted of 103 sedentary women, divided into two groups: 57 obese and 46 normal-weight women. Waist circumference (WC) and hip circumference (HC) were measured to calculate the waist-to-hip ratio (WHR), and maximal respiratory pressures (Pmax) were determined using an analog vacuum manometer to ± 300 cm H2O.
