BACKGROUND: The correlation between arch structure and injury may be related to the fact that foot structure influences foot function. Foot structure is often defined by arch height, although arch flexibility may be just as important to form a more complete description. We propose an arch flexibility classification system, analogous to arch height classification, and then use the classification system to examine the relationship between arch flexibility and arch height. METHODS: Arch height index was calculated in 1,124 incoming military cadets, of whom 1,056 had usable data...

A high proportion of children have overweight and obesity in the United States and other countries. Accurate assessment of anthropometry is essential to understand health effects of child growth and adiposity. Gold standard methods of measuring adiposity, such as dual X-ray absorptiometry (DXA), may not be feasible in large field studies. Research staff can, however, complete anthropometric measurements, such as body circumferences and skinfold measurements, using inexpensive portable equipment. In this protocol we detail how to obtain manual anthropometric measurements from children, including standing and sitting height, weight, waist circumference, hip circumference, mid-upper arm circumference, triceps skinfold thickness, and subscapular skinfold thickness, and procedures to assess the quality of these measurements...

Our objective was to describe patterns and predictors of sedentary behavior (sitting time) over 10 years among a large Canadian cohort. Data are from the Canadian Multicentre Osteoporosis Study, a prospective study of women and men randomly selected from the general population. Respondents reported socio-demographics, lifestyle behaviors and health outcomes in interviewer-administered questionnaires; weight and height were measured. Baseline data were collected between 1995 and 1997 (n = 9418; participation rate = 42%), and at 5- (n = 7648) and 10-year follow-ups (n = 5567)...

BACKGROUND: Under normal nutritional and health conditions, body height, weight and head circumference are significantly related. We hypothesize that the apparent general association between weight, height and head circumference of the growing child might be misleading. METHODS: We re-analyzed data of 7444 boys and 7375 girls measured in East-Germany between 1986 and 1990, aged from 0 to 7 years with measurements of body length/height, leg length, sitting height, biacromial shoulder breadth, thoracic breadth, thoracic depth, thoracic circumference, body weight, head volume, percentage of body fat, and hip skinfold vertical, using principal component analysis...

BACKGROUND: Foot anthropometry may be altered during pregnancy. Pregnant women often report lower-extremity pain that may be related to these alterations. The Arch Height Index Measurement System is a common method of foot arch assessment; however, the required calipers are costly and are not widely available. Thus, we compared the reliability of a digital photogrammetry method of arch height index (AHI) assessment with that of the Arch Height Index Measurement System. METHODS: Ten pregnant women (mean ± SD: age, 29 ± 4 years; height, 166...

Background and purpose - When children with irregular body proportions or asymmetric limbs present, it may be unclear where the pathology is located. An improved understanding of the clinical ratio between upper extremity, lower extremity, and spine length may help elucidate whether there is disproportion between the trunk and limbs, and whether there is a reduction deficit of the shorter limb rather than hypertrophy of the longer limb. Patients and methods - We used the Brush Foundation study of child growth and development, which was a prospective, longitudinal study of healthy children between the 1930s and the 1950s, and we collected serial clinical measurements for 290 children at 3,326 visits...

Anthropometry and neuromuscular fitness have been shown to relate with taekwondo (TKD) performance; however, little information is available on the variation of these fitness components by sex and age in athletes practicing this sport. The aim of the present study was to examine the anthropometry and neuromuscular fitness of TKD athletes by sex and age. A total of 393 athletes (7-48 years old), separated into six age groups (7-9, 10-11, 12-13, 14-17, 18-32, and 33+), were examined for anthropometry and performed a series of neuromuscular fitness tests (flexibility, agility, muscle power, and isometric strength)...

It has been suggested that foot type consider not only foot structure (high, normal, low arch), but also function (over-pronation, normal, over-supination) and flexibility (reduced, normal, excessive). Therefore, this study used canonical regression analyses to assess which variables of foot structure, function, and flexibility can accurately discriminate between clinical foot type classifications. The feet of 61 asymptomatic, healthy adults (18-77 years) were classified as cavus (N=24), rectus (N=54), or planus (N=44) using standard clinical measures...

During school hours, children can sit for prolonged and unbroken periods of time. This study investigated the impact of an 8-month classroom-based intervention focusing on reducing and breaking-up sitting time on children's cardio-metabolic risk factors (i.e., body mass index, waist circumference, blood pressure) and perceptions of musculoskeletal discomfort. Two Year-6 classes (24 students per class) in one primary school were assigned to either an intervention or control classroom. The intervention classroom was equipped with height-adjustable desks and the teacher was instructed in the delivery of pedagogical strategies to reduce and break-up sitting in class...

Major challenges to the current childhood obesity epidemic include availability of prevention and/or treatment programs that are affordable and acc5essible. We evaluated the change in several modifiable, obesity-related cardiovascular disease risk factors after participation in Fit2Play™, a structured afterschool program housed in a large urban county parks system. Children ages 6-14 who participated in Fit2Play™ in one of 34 parks for one school year during a five-year period (2010-2015) had height, weight, 4-site skinfold thicknesses, systolic/diastolic blood pressure (SBP/DBP), fitness tests, and a health/wellness behavior/knowledge test collected at the beginning and end of the school year...

[Purpose] The purpose of this study was to determine the effects on the trunk length and pelvic torsion of healthy individuals that arise from crossing the right leg while sitting. [Subjects and Methods] The subjects in this study were 30 healthy individuals consisting of 18 males and 12 females. The subjects were instructed to sit on a chair, the height of which was adjustable, so that their knee and hip joints were bent at 90°. For the study, they sat stripped to the waist, with the back and hips bare. They were then instructed to perform a one-leg-crossed sitting posture by placing the right leg on the top of the left knee...

OBJECTIVE: The shape of the current physical and computational surrogates of children used for restraint system assessments are based largely on standard anthropometric dimensions. These scalar dimensions provide valuable information on the overall size of the individual, but do not provide good guidance on shape or posture. This study introduced development of a parametric model, which statistically predicts individual child body shapes in seated postures with a few given parameters...

PURPOSE: An athlete's ability to recover quickly is important when there is limited time between training and competition. As such, recovery strategies are commonly used to expedite the recovery process. The purpose of this study was to determine the effectiveness of both cold water immersion (CWI) and contrast water therapy (CWT) compared to control on short-term recovery (<4h) following a single full-body resistance training session. METHODS: Thirteen males (age, 26 ± 5 years; weight, 79 ± 7 kg; height, 177 ± 5 cm) were assessed for perceptual (fatigue and soreness) and performance measures (maximal voluntary isometric contraction (MVC) of the knee extensors, weighted and unweighted countermovement jumps) prior to and immediately following the training session...
