ObjectiveThe purpose of the study was to compare actual energy expenditure, using the Actiheart, Actiband and Indirect Calorimetry, with predicted energy expenditure using traditional methods of calculating and assessing people's energy expenditure with diet and activity diaries and pedometers
Design
The study was an observational design, whereby subjects' habitual dietary intakes and physical activity levels were assessed using multiple methodologies; the aim being to compare and validate these methodologies. Dietary intake was assessed using a 7 -day diet diary and physical activity was assessed using Indirect Calorimetry, pedometers, Actiband and Actiheart. All the data collected was recorded using the data collection form.
Results
Twenty three people were screened for potential participation in the study and all of the twenty three screened were used in the study. Ten of the subjects were tested more than once, creating 33 sets of data. Of the twenty three subjects 15 females (1 Ethnic original, 1 Asian, 12 Caucasian) and 8 male (1 Ethnic origin, 7 Caucasian). Their mean age, height and weight were 27.3 (plus or minus 5.29 years) 1.70m (plus or minus 0.09 m and 67.2kg (plus or minus 12.8kg) respectively.
The mean energy expenditure measured by the Actiheart was 2118 kcals/day with a S.D 607.5, te mean energy expenditure from the Actiband was 2624 kcals/day, S.D. 607.5 and the mean of the diet diary energy intake measurement was 2198kcals/day and S.D 710
Conclusions
This study provides preliminary data suggesting that Actiband and Actiheart are valuable tolls in assessing daily physical activity. The results gained indicate that the Actiheart is a good indicator for physical activity levels of an individual and is a good guide as to actual energy expenditure and thus energy intake. It can also be concluded that these trends support previous research (Brage et al, 2003) that the Actiheart appears to be a promising tool for the assessment of physical activity in populations. The data collected in the current study does not support pedometry as a reliable method of assessing physical activity but pedomoeters would appear to be a good method in health promotion initiatives for promoting physical activity. The diet diaries proved to be a helpful validation tool of actual energy intake compared to energy expenditure as all subjects were wight stable. - presented at
