Abstract (eng)
The aim of this study was to find out which of the 3 different methods: a 7-dayactivity
protocol, an acceleration measurement instrument (accelerometer, 1
week) or an IPAQ (International Physical Activity Questionnaire, on the last
day), is most suitable to display the energy use of Austrian adults.
For this purpose the listed questionnaires and a 3-day-dietary record for
measuring the food intake were answered and the accelerometer was worn by
76 persons (18 to 64 years old).
In order to declare the adequacy of the methods the calculated and measured
energy use was compared with the energy intake (in kilocalories) and the PAL
(Physical Activity Level).
These measurements showed, that the energy use (in kcal) can be measured
by the accelerometer (p=0,01) and the activity protocol (p=0,01). However, the
investigation with the IPAQ did not show significant results like the other
methods.
In addition, the PAL calculation also showed a presentability of the energy use
by the accelerometer (p=0,05) and the activity protocol (p=0,05).
Due to the good results for the accelerometer and the less extensive activity
protocol, it could maybe be possible to use the protocol frequently for energy
measurements in the future.
In summary the study showed, that in order to create a representative energy
balance it is necessary to do a daily protocol or wear a device for measuring the
energy use.
