In this article, we introduce the different tools and methods used to measure physical activity.
Measuring physical activity levels can reveal lots of useful information about a patient, and can help inform exercise prescription. For example, it might be possible to find out if someone accumulates most of their physical activity during the week, or at the weekend, through occupational activities or active transport. Measurements of physical activity can also reveal what level of intensity of physical activity a patient is engaging in, and whether they are meeting physical activity guidelines. In other words, tools used to measure physical activity have the capacity to measure the frequency, intensity, time and type of physical activities being performed. However, not all tools used to measure physical activity can measure all of these variables. For the purpose of this article we will concentrate on methods used to measure physical activity which are used in clinical situations. Whole room calorimetry, indirect calorimetry, observation and doubly labelled water are expensive methods of measuring physical activity and require training and skill to administer and analyse. These methods are generally reserved for research and will not be covered in this step. Common clinical methods of measuring physical activity include heart rate monitoring, questionnaires, accelerometers, and pedometers.
Heart rate monitorsHeart rate monitors are an excellent method of indirectly measuring the intensity of physical activity as well as the duration and frequency. On their own they do not give you information on the type of activity being performed but can easily be used in combination with an activity diary to gain this information if needed.
Estimation equations have been developed to convert heart rate to energy expenditure. This way you can determine how many calories are being expended. Remember however that this is just an estimation of calorific expenditure and subject to assumptions and error. With such equations the person’s age, fitness, gender and body mass will all effect the accuracy of results. AccelerometersAccelerometers are small light devices and can be attached almost anywhere on the body, and give you information on the duration, frequency, time and intensity of physical activities. They do not however give information on the type of activity being performed.
The most common sites for attachment are at the level of the hip, on the ankle and on the wrist. Since physical activity patterns vary so much it is advisable to wear the monitor for a minimum of four days. Preferably one of these four days should be a weekend day. PedometersPedometers count steps taken. They are simple and affordable, and are frequently used in public health initiatives and in large-scale research.
As pedometers are now readily available on smart phones, they are a good first step with which patients can learn to monitor their own physical activity levels. New generation activity monitorsSome devices have combined several methods of measurement together in order to provide a more accurate representation of physical activity levels.
QuestionnairesQuestionnaires can be very subjective, and unfortunately the accuracy of questionnaires and surveys often falls victim to recall bias. They are however affordable, easy to use and administer, and often don’t take long to complete. Some are completed in private by the patient, while others are administered in an interview format by the clinician.
Despite this, questionnaires can help you gather essential information quickly and should be encouraged over no measurement of physical activity at all and over simple informal probing. If you work a lot with a particular patient population, have a look at the literature, and see if you can find a questionnaire which is commonly used and validated in that population. Some examples of questionnaires include:
Measuring physical activity in paediatric populationsFinally a note on the physical activity levels of children. The behaviour of children differs from that of adults, as we will see in this article as well as this. Physical activity can be vigorous, spontaneous, short-lived and is often associated with play. Objective tools such as accelerometers are recommended to measure the physical activity levels of children rather than questionnaires, especially if used to inform an individual exercise prescription. |
