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. understanding of the validity of consumer-based physical activity monitors and also evaluate the potential of estimating energy expenditure using built-in technology in Smartphones. 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.

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).

Get this from a library. The validity and reliability of heart rate as a measure of daily energy expenditure. [Richard A Washburn]. Background. Accurate measurement of free-living energy expenditure is vital to understanding changes in energy metabolism with aging.

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.

by having a large sample of people rate a measure in terms of whether it appears to measure what it is intended to—it is usually assessed informally. 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. m Heart rate thresholds also have been used to determine the time or percent of time that individuals spend above.

e people. 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. Sawatzky BJ, Miller WC and Denison I (). Measuring energy expenditure using heart rate to assess the effects of wheelchair tyre pressure.

The three portable systems capable of providing a continuous measurement of ˙VO 2 and ventilation for long periods are (1) the Total Energy Expenditure Measurement system (TEEMAeroSport, Ann Arbor, Mich.), (2) the COSMED K2 (Vacumed, Ventura, Calif.), and (3) the Oxylog (P.
