Correction equations to estimate body fat with plicometer WCS dual hand

Introduction: This study aimed to propose regression equations for the correction of fat percentage values obtained with the WCS Dual Hand skinfold caliper, using the Lange skinfold caliper as a reference. Methods: This study evaluated 112 undergraduate students from the Physical Education and Physical Therapy programs of the Faculdade Dom Bosco, located in Curitiba, Paraná, Brazil. Of these, 58 women were 24.9±5.8 years old and 54 men were 27.6±7.9 years old. The evaluation comprised the following measurements: height, body mass, and nine skin folds with WCS Dual Hand and Lange skinfold calipers used in biceps, triceps, subscapular, suprailiac, pectoral, average axillary, medial thigh, abdominal, and calf measurements. Results: Through the simple linear regression analysis, eight equations were generated to correct the relative body fat obtained with equations commonly used in Brazil. For these correction equations, R2 was between 0.830 and 0.961 and p-value was 0.000 for all measurements. Conclusion: These results indicate the use of equations for the correction of estimated values of relative body fat measured with the WCS Dual Hand skinfold caliper, whenever the Lange skinfold caliper is not available, in order to minimize the difference between them.
