Super accurate energy expenditure insights of normal daily life

Objective and accurate information about a patient’s energy expenditure during daily life is of fundamental importance for research in addition to clinical practice. Such information can help to gain a clear insight into the lifestyle of a patient and the effectiveness of weight and activity intervention programmes, supports in evaluation and optimization of therapy on both an individual and group level. There are other methods that provide rough indications of a persons energy expenditure, however VitaMove with it’s fundamentally different method of measuring, which provides extremely precise results. Therefore VitaMove can also be of relevance for athletes and sports medicine.

Method

VitaMove’s activity recognition is used to classify the type of activity (lying, stand, walk, running, cycling, etc.). These activities are converted into their energy equivalent using M.E.T. (Metabolic Equivalent Task) tables. These are tables where by each activity type corresponds with a certain energy range. These MET tables are widely referred to in medical publications. In addition to this by using the Metabolic Rest Rate of a subject which depends on gender, height and weight, M.E.T. values become subject specific. The movement intensity or motility is used to narrow the range in M.E.T. values for each activity type thereby giving an increased accurate estimation of the energy consumed. Due to this it is possible to discriminate between slow, medium and high energy expenditures. For example, Nordic walking as opposed to strolling. An ECG signal is also present. The heart rate is used to make the energy expenditure even more precise. The heart function helps to discriminate between normal walking and walking with a heavy backpack. These three steps lead to one of the most accurate energy expenditure estimated today available in the market.

Outcomes

Accurate energy expenditure quantification

Total Energy Expenditure is the sum of Rest Metabolic Rate and physical activity based energy expenditure. The current VitaMove energy expenditure report shows cumulative energy expenditure over the total measurement period or over 24 hour time periods. However it is also possible to only look at the physical activity energy expenditure consumed per minute or per hour of day.

Energy intake

A care provider can easily enter energy intake levels of the various meals and snacks in case the subject keeps a simple food diary, often standard practice in weight management programs.

Energy balance in time

Display the energy balance as a function of time from energy (food)-Intake and energy expenditure. If this E-Balance level is above zero, there is an excess of energy and below zero there is an energy deficit. The cumulated E-Balance, after a number of days, should be below (or above) zero to reduce (or gain) weight over that period of time. This can help dieticians to provide valuable feedback to the subject on how often and how much to best eat.

Energy expenditure per activity

The energy expenditure per activity is provided, including its total duration and percentage contribution to the total energy expenditure.

Accurate and advanced Rest Metabolic Rate

The VitaMove software supplies advanced methods to calculate Rest Metabolic Rate via various anthropometric measures.
