Estimating the reliability of glycemic index values and potential sources of methodological and biological variability
glycemic index variability healthy volunteers insulin index glycated hemoglobin
2018/12/14
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...
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...

CARDIO-VASCULAR REACTION AFTER EXERCISE TEST AND SELECTED PARAMETERS OF HEART RATE VARIABILITY
cardio-vascular reaction exercise test heart rate variability
2009/4/2
The aim of our investigation was to check up the dependence between a type of cardiovascular reaction after exercise test and some selected parameters of heart rate variability (HRV) analysed during...
Monitoring of the autonomic nervous system activity during post-marathon recovery by spectral analysis of heart rate variability: a case study
heart rate variability exercise marathon recovery
2009/4/2
Introduction: Vigorous physical exertion, such as a marathon, evokes long lasting changes in the autonomic cardiac regulation and peripheral fatigue.Aim of the study: We investigated changes in the ...
