The efficacy of heart rate as a surrogate for energy expenditure is rooted in the assumption of a linear function between heart rate and energy expenditure, but its validity and reliability in older adults remains by: Pearson correlation between usual daily energy expenditure measured by the instrument and the mean of the 24 hour recalls was After subdividing the self-reported daily energy expenditure and the mean of the 24 hour recalls into quintiles, % of the participants remained in the Cited by: The lowest variation in heart rate occurred in the fourth stage ([almost equal to]90% maximum heart rate) with heart rate varying 5 +/- 2 b[middle dot]min-1 (95% confidence interval for.

Introduction. Physical activity energy expenditure (AEE) is the most variable component of total energy expenditure (TEE). In very active individuals daily TEE can be twice as much as resting energy expenditure, 1 and during heavy sustained exercise in the Tour de France a fivefold increase has been described.

t exercise and recovery would be useful in team sports. Fourteen state-level male rugby union players (mean ± SD: age, 22 ± 4 years; body mass, ± kg; height, ± m, body fat, 18 ± 6%) participated in this study.

Energy expenditure was measured by the SenseWear Armband (SWA) and validated against indirect calorimetry as the criterion measure during a minute rugby. This relation serves as the foundation for existent calibrated heart rate measures developed to provide estimates of energy expenditure in kcal/day or kJ and that can be used to discriminate between different activity intensities.

Methods: Two hundred twenty-four older adults (% women, % men, mean age ± yr) were randomly selected from the Guangzhou Biobank Cohort Study, a prospective cohort of older Chinese in Southern China.

To examine the test-retest reliability, the participants completed the IPAQ-C twice during a 7-d interval. The criterion validity of the IPAQ-C was tested with pedometry.

Improving the accuracy of a survey is the focus of Mark S. Litwin's book, which shows how to assess and interpret the quality of survey data by thoroughly examining the survey instrument used.

He explains how to code and pilot test new and established surveys. In addition, he covers issues such as: how to measure reliability (including test-retest, alternate form, internal consistency, inter.

Energy Expenditure Measuring Activity Energy Expenditure with the Actiheart. The Actiheart is a compact, chest-worn device that records ECG and physical activity in one combined, light-weight waterproof unit and uses a system of branched modelling to use both the activity and heart rate to calculate Activity Energy Expenditure (AEE).

CHAPTER 3 VALIDITY AND RELIABILITY 3 VALIDITY AND RELIABILITY INTRODUCTION In Chapter 2, the study’s aims of exploring how objects can influence the level of construct validity of a Picture Vocabulary Test were discussed, and a review conducted of the literature on the various factors that play a role as to how the.

Summary. Total energy expenditure of the heart can be directly determined by cardiac oxygen consumption (Vo 2) according to the energy equivalence of oxygen in aerobic metabolism (1 ml O 2 = J).

However, Vo 2 determination of an in situ heart is invasive and not always possible, particularly in clinical settings.

To circumvent this problem, various methods to predict Vo 2 have been Cited by: 9. Heart Rate Monitor. Heat rate monitors, usually worn on the chest or wrist, have an electrocardiogram (ECG) transmitter that sends signals to the receiver which calculates average heart rate within 5 to 15 seconds intervals and displays it as beats per gh more expensive than pedometers and accelerometers, data obtained from heart rate monitors can be transferred to a computer, are.

The first study (Chapter 3) specifically evaluated the utility of various. an activity monitor for concurrent validity, and with aerobic fitness and body composition for construct validity.

Validity has been defined as the extent to which an instrument assesses the true exposure of interest4. This definition is frequently referred to as internal validity and implies an absolute measure of the variable of interest.

UCLA School of Medicine, Los Angeles Aimed at helping readers improve the accuracy of their survey, Litwin's book guides in assessing and interpreting the quality of their survey data by thoroughly examining the survey instrument used.

The book also explains how to code and pilot test new and established surveys. In addition, it covers such issues as how to measure reliability (e.g., test 5/5(1). quality on energy expenditure (EE), heart rate (HR) and EE:HR when fed near maintenance and fasting. The experiment consisted of four simultaneous crossovers, with 21d for adaptation before measures.

Reliability Measure for Multi-Item Scales Total scale variance = sum of item variances and all item covariances [k/(k-1)]* [1- (sum of item variances/total scale variance) − Where k = number of items Range between 0 and 1 Criteria for assessment − ≥ = adequate reliability for group comparisons − ≥ = adequate reliability for File Size: KB.

But a good way to interpret these types is that they are other kinds of evidence—in addition to reliability—that should be taken into account when judging the validity of a measure. Here we consider four basic kinds: face validity, content validity, criterion validity, and discriminant validity.

The weaknesses in assessing accurate energy expenditure by accelerometry are mainly due to the applied algorithms, and to a much lesser extent, due to the technology of the accelerometers.

Therefore, it is necessary to improve the calculation of energy expenditure by using different regression equations for different kinds of by: The first question is related to validity and second to reliability. Validity and reliability are two important characteristics of behavioral measure and are referred to as psychometric properties.

It is important to bear in mind that validity and reliability are not an all or none issue but a matter of degree. Validity.

The Wii Balance Board (WBB) is designed to test balance, but there is little software used in balance tests, and there are few studies on reliability and validity.

Thus, we developed a balance assessment software using the Nintendo Wii Balance Board, investigated its reliability and validity, and compared it with a laboratory-grade force by: The 7th question of IPAQ-SF and its total score were used in statistical analysis of the current study since this question investigates the sedentary behavior time.

Heart rate is a measure of the number of heart beats occurring over a 60 second period and can be measured at rest and during exercise. Resting heart rate is measured in order to get a baseline that can be used to assess and monitor a person against over time.Reliability is the degree to which your measure is free of random error--reliability tests always measure things twice and check for variation 4.

Validity refers to the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure.Yuan, J. et al.: THE RELIABILITY AND SENSITIVITY OF INDICES RELATED Kinesiology 40() heart rate (P 2) was measured using the same inter-val length.
