BACKGROUND To effectively promote physical activity (PA) and quantify the effects of PA interventions for pregnant women, PA measurement during pregnancy needs improvement. The purpose of this study was to assess PA monitor output during a controlled, treadmill walking protocol among pregnant women at 20- and 32-weeks gestation. METHODS Women (N = 43) wore an Actigraph accelerometer, NL1000, ...

OBJECTIVE To evaluate waist-to-height ratio (WTHR), waist girth and body mass index (BMI) as predictors of cardiovascular risk factors in Australian Aborigines. DESIGN Indices were examined as predictors of mean blood pressures (BP), blood lipids, glucose, insulin and as predictors of hypertension, decreased HDL-cholesterol, elevated glucose and type 2 diabetes. SETTING Aboriginal communiti...

To investigate anthropometric characteristics of Chinese professional female marathoners and suitable predicted variables correlated with their personal bests (PB), 96 Chinese female long-distance runners were divided into international (< 2 h 34 min), national (2 h 34 min~2 h 45 min) and average (2 h 45 min~3 h 19 min) levels according to their PB in marathon during the process of talent ident...

Inductive plethysmography (IP) sensors and oscillator modules were assessed for their potential use in the ambulatory monitoring of abdominal girth in subjects with irritable bowel syndrome (IBS) in order to objectively quantify their bloating symptoms. A dedicated microprocessordata logger was designed to record over 24 h the frequency output of IP oscillators connected to a belt around the su...

The objective of the study was to assess the dimensionality of seven linear traits (body condition score, body stature, body length, heart girth, navel height, body depth and flank circumference) in Nguni cows using factor analysis and indicate the relationship between the extracted latent variables and calving interval (CI) and age at first calving (AFC). The traits were measured between Decem...

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
