Samango-Sprouse, Carole A.; Stapleton, Emily J.; Aliabadi, Farhad; Graw, Robert; Vickers, Rebecca; Haskell, Kathryn; Sadeghin, Teresa; Jameson, Robert; Parmele, Charles L.; Gropman, Andrea L. – Autism: The International Journal of Research and Practice, 2015
Studies have shown an increased head circumference and the absence of the head tilt reflex as possible risk factors for autism spectrum disorder, allowing for early detection at 12 months in typically developing population of infants. Our aim was to develop a screening tool to identify infants prior to 12 months at risk for autism spectrum…

Gonzalez-Aguero, A.; Vicente-Rodriguez, G.; Ara, I.; Moreno, L. A.; Casajus, J. A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
To determine the accuracy of the published percentage body fat (%BF) prediction equations (Durnin et al., Johnston et al., Brook and Slaughter et al.) from skinfold thickness compared to air displacement plethysmography (ADP) in children and adolescents with Down syndrome (DS). Twenty-eight children and adolescents with DS (10-20 years old; 12…

Hannon, James C. – Journal of School Health, 2008
Background: This study examined physical activity (PA) levels of overweight and nonoverweight African American and Caucasian students (n = 198) during game play in physical education classes. Methods: Body fat percentages (%BFs) were determined using the skinfold technique and Slaughter et al prediction equations. Girls were classified as…

Sutton, Robert A.; Miller, Carolyn – College Student Journal, 2006
Body composition measurements vary greatly in degree of measurement difficulty and accuracy. Hydrostatic weighing, chemical dilution or their equivalents were the accepted "gold" standards for assessing fat mass. Dual Energy X-ray Absorptiometry (DEXA) is fast replacing these techniques as the preferred standard. However, these direct measurement…

Vehrs, Pat R.; George, James D.; Fellingham, Gilbert W.; Plowman, Sharon A.; Dustman-Allen, Kymberli – Measurement in Physical Education and Exercise Science, 2007
This study was designed to develop a single-stage submaximal treadmill jogging (TMJ) test to predict VO[subscript 2]max in fit adults. Participants (N = 400; men = 250 and women = 150), ages 18 to 40 years, successfully completed a maximal graded exercise test (GXT) at 1 of 3 laboratories to determine VO[subscript 2]max. The TMJ test was completed…

Hannon, James C.; Ratliffe, Thomas; Williams, Daniel P. – Research Quarterly for Exercise and Sport, 2006
The body mass index (BMI), or the ratio of weight in kilograms to the square of height in meters, is widely used to determine the presence or absence of overweight and obesity in adults. Although many consider BMI an acceptable clinical surrogate of body fatness, it does not differentiate between fat and fat-free tissues. Thus, children and…
