Book Description
This study developed prediction formulas (PF) for residual volume (PRV) and functional residual capacity (PFRC) using the variables age (A), height (Ht), weight (Wt), chest depth (CD), and smoking history (SH)in 100 male subjects between the ages of 18-69 years. A and Ht were the only variables which contributed significantly to PRV. A, Ht, and Wt were the only variables to contribute significantly to PFRC. A test-retest correlation between two trials of RV (r=.99) and FRC (r=.98) determinations indicated that reliable measures were taken by the closed circuit oxygen dilution technique. Through the use of multiple step-wise regression the following PRV and PFRC formulas were developed: PRV (liters)=.0260376(A) + .0256005(Ht) - 3.89794 PFRC (liters) = .0493365(Ht) + .0116958(A) - 00919313(Wt)-6.20966 The standard error of estimation (S.Y.E.) of the PRV and PFRC formulas (241 and 403 mls, respectively) were all lower than those reported by Boren et al . (1966) (B), Crapo et al . (1982) (C), Goldman and Becklake (1959) (GB). and Grimby and Soderholm (1963) (GS). The variation (R ~) attributed to the independent variables was .72 and .4l for PRV and PFRC, respectively. These R' values were higher than those reported by B, C, and GS. Using the data obtained in this study, an ANOVA with repeated measures followed by a Scheffe' post hoc test determined significant differences (p.05) between PRV and the PF of C and GB.

A Comparison of Body Density and Percent Body Fat as Computed Using Four Different Lung Volumes in the Hydrostatic Weighing Technique

ISBN:
Category : Human body
Languages : en
Pages : 132
Book Description
This study compared body density (BD) and percent body fat (%BF) arrived at by using four different lung volumes in the hydrostatic weighing (HW) procedure. The four lung volumes were residual volume as measured in air (RV-dry), residual volume as measured immersed in water (RV-wet), functional residual capacity, as measured immersed (FRC), and total lung capacity as measured immersed (TLC). The closed circuit oxygen dilution technique was used to measure all lung volumes.

A Comparison of Methods Used to Estimate Body Density

ISBN:
Category : Body composition
Languages : en
Pages : 0
Book Description
The reliability of two different makes of skinfold calipers, the Harpenden and the Lange, was tested on a group of physical education students. The reliabilities reported were almost identical. The accuracy of skinfold regression formulas for predicting density of the human body was also tested. The formulas of Young et al (57) and Sloan et al (49) did give an accurate estimate, but that of Katch and Michael (35) reported a non-significant correlation at the .05 level. Different techniques of hydrostatic weighing were examined and reliabilities were reported for each method. The inspiration technique using a measured residual volume gave the highest reliability. The residual volume was estimated and measured directly to determine if there would be a significant difference in body density between these two methods. However, when the mean of the scores was taken there was no significant difference at the .05 level. The body density estimate, obtained by hydrostatic weighing v/as used in three formulas, which had been developed by previous researchers, to estimate the percentage body fat. At the .05 level of significance there was no difference among the three estimates of percentage body fat.
