Prediction equations for body composition of Japanese adults by B‐mode ultrasound

Abstract

A total of 117 Japanese subjects (62 men and 55 women) volunteered for the study. Subcutaneous adipose tissue (AT) and muscle thicknesses were measured by B-mode ultrasonography at nine sites of the body. Body density (BD) was determined the hydrodensitometry. Reproducibility of thickness measurements by ultrasonography was high (r = 0.96-0.99). Correlations between AT thickness and BD ranged from -0.46 (gastrocnemius) to -0.87 (abdomen) for males and -0.46 (gastrocnemius) to -0.84 (abdomen) for females. A higher negative correlation (r = -0.89) was observed for the sum of AT thicknesses (forearm, biceps, triceps, abdomen, subscapula, quadriceps, hamstrings, gastrocnemius, and tibialis anterior) both in males and in females. Slightly lower coefficients were observed between muscle thickness and LBM (r = 0.36 to r = 0.70 for males and r = 0.44 to r = 0.55 for females). Prediction equations for BD and LBM from AT and muscle thickness were obtained by multiple regression analysis. Cross-validation on a separate sample (33 men and 44 women) showed an accurate prediction for BD. The present findings suggest that B-mode ultrasonography can be applied in clinical assessment and field surveys. © 1994 Wiley-Liss, Inc.

Eight days KAATSU-resistance training improved sprint but not jump performance in collegiate male track and field athletes

“…Validity of the image reconstruction and distance measurements was established by comparing the ultrasonic and manual measurements of tissue thicknesses using human cadavers (Fukunaga et al, 1989). The CV of this MTH measurement was 1% (Abe et al, 1994).…”

Maternal abdominal subcutaneous fat thickness as a predictor for adverse pregnancy outcome: a longitudinal cohort study

“…13,14 The significance of fat distribution is obvious, with central abdominal obesity (adipose tissue around the trunk) increasing the risk of cardiovascular disease, hypertension and diabetes, [15][16][17][18] whereas peripheral adiposity (adipose tissue around the bottom and thighs) appears to be protective. 17,19 Although impractical for pregnancy, central adiposity can be reliably assessed with computed tomography, magnetic resonance imaging or body densitometry. Abdominal subcutaneous fat thickness (SFT) correlates significantly with a range of obesity-related diseases such as diabetes and cardiovascular disease.…”

Association of vigorous physical activity with age-related, site-specific loss of thigh muscle in women: the HIREGASAKI study

“…12 The measurements were taken while the subjects stood with their knees extended and relaxed. A 5-MHz scanning head was placed on the measurement site without depressing the dermal surface.…”

“…Subcutaneous fat thickness was also measured using ultrasound at 6 sites, as described previously. 12 Percent body fat was estimated from subcutaneous fat thickness using an ultrasound-derived prediction equation, 12 and fat-free mass (FFM) was calculated. Body mass and standing height were measured to the nearest 0.1 kg and 0.1 cm, respectively, by using a height scale and an electronic weight scale.…”
