Estimating the reliability of glycemic index values and potential sources of methodological and biological variability
glycemic index variability healthy volunteers insulin index glycated hemoglobin
2016/9/7
Background: The utility of glycemic index (GI) values for chronic disease risk management remains controversial. Although absolute GI value determinations for individual foods have been shown to vary ...
Differing Roles of Functional Movement Variability as Experience Increases in Gymnastics
Task experience inter-trial variability performance inter-segmental coordination gymnastics
2016/7/7
Current theories, like Ecological Dynamics, propose that inter-trial movement variability is functional when acquiring or refining movement coordination. Here, we examined how age-based experience lev...
Variability in commercial ginseng products: an analysis of 25 preparations
Ginseng ginsenosides eleutherosides
2016/6/13
Because dietary supplements are not subject to
the same regulations that pharmaceuticals are, there is concern
among medical professionals that these products may lack purity
or potency.
Heart rate variability and fatty acid content of blood cell membranes: a dose-response study with n−3 fatty acids
sudden cardiac death cardiac arrest ventricular arrhythmias
2016/6/1
Dietary intake of long-chain n23 polyunsaturated
fatty acids (PUFA) may protect against sudden cardiac
death, an event that may be predicted by measurement of heart
rate variability (HRV).
Ultra-Short-Term Heart Rate Variability is Sensitive to Training Effects in Team Sports Players
Court sports athletic monitoring cardiac autonomic system futsal
2016/1/9
The aim of this study was to test the possibility of the ultra-short-term lnRMSSD (measured in 1-min post-1-min stabilization period) to detect training induced adaptations in futsal players. Twenty-f...
Non-Linear Heart Rate Variability and Risk Stratification in Cardiovascular Disease
heart rate variability risk stratification non linear post myocardial infarction congestive heart failure
2015/7/31
Traditional time and frequency domain heart rate variability (HRV) have cardiac patients at risk of mortality post-myocardial infarction. More recently, non linear HRV has been applied to risk stratif...

2014/12/4
Reference point indentation (RPI) has emerged as a novel tool to measure material-level biomechanical properties in vivo. Human studies have been able to differentiate fracture versus non-fracture pat...
Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the...
