Actical ®

Activity and Caloric Expenditure, Now with Step-Count.

(Actual Size: 28 x 27 x 10 mm)

Actical Physical Activity Monitors provide an objective, quantifiable measure of Physical Activity and Energy (Caloric) Expenditure for your research. Activity level thresholds (cut point) determination and quantitative activity analysis are recognized as being important components of weight management and sports medicine research. They can be a valuable measurement tool in any area where exercise plays a critical role.

Actical is a physical activity monitor based on our proven Actiwatch actigraphy-based data logging system, using an omnidirectional accelerometer. Digital integration data acquisition incorporates intensity of movement into the Activity Count total.

Actical Applications:
  • Weight Management
  • Nutrition
  • Exercise
  • Rehabilitation
  • All General Physical Activity Monitoring Requirements
The Actical Advantage
  • Waterproof - bathe, shower and swim with no fear of data loss or damage
  • Digital Integration - Accurately incorporates both intensity and duration
  • Omnidirectional sensor
  • Compact size & weight - 28mm x 27mm x 10mm and only 17 grams!
  • 64k memory (45 days using one minute epoch)
  • 6-month battery life (user-replaceable)
  • Repeated calibrations not required
  • Built-in event marker

"The Mini Mitter [Actiwatch] not only has the advantage of being omnidirectional, but it is also smaller [than the other product used in the study] and waterproof."

Actical Energy (Caloric) Expenditure Analysis

Actical software includes Active Energy Expenditure (AEE) and Metabolic Equivalent (MET) Algorithms based on carefully validated studies in which a wide range of subjects performed a variety of tests ranging from keyboarding to treadmill running. Actical's activity count data is converted into minute-by-minute energy expenditure. This is used to calculate daily, hourly, and custom interval caloric consumption.

Actical Activity Analysis

Collected activity data can be evaluated in many ways. Multiple-day actograms, actogram zoom, and actogram average functions provide graphical and statistical presentation of activity count data. Activity data can be exported in an ASCII data format for additional analysis.

Example Actical Activity Screen

This is an expanded actogram showing the activity levels from a participant during the 2003 New York City Marathon. Note the high levels of sustained activity.

Actical Software gives you a number of ways to look at your data. Here are just a few of them:
  • Total Energy Expenditure (kcals)
  • Average Energy Expenditure (kcals per minute)
  • Total Activity (counts) * Average Activity (counts per minute)
  • Time Interval Duration (minutes)
  • Total Energy Expenditure Within Each Activity Range (kcals)
  • Sedentary, Light, Moderate, and Vigorous activity ranges
  • Average Energy Expenditure Within Each Activity Range (kcals per minute)
  • Accumulated Time Within Each Activity Range (minutes)
  • Ratio of Accumulated Time Within Each Activity Range to Total Time (%)
Statistics are computed in the software for:
  • The whole data set
  • Each day
  • Each hour of each day
  • Custom time intervals selected by the user

ActiReader™

 

ActiReader directs communication between your PC and Actical. It is connected to the PC via an RS-232 serial cable, and communicates with Actical using a short range telemetric link.
