Wearable Personal Activity and Fitness Trackers

Wearable health and fitness tracking devices are giving more information than ever to individuals about activity levels, calorie burning, sleep patterns, heart rate, and other measures, depending on the type of device.  Since the technology is constantly being updated, it is best to research the best devices online for the most current features and price points.  The three types of devices – fitness trackers, smartwatches and running watches – are described in more detail below.  (Note: Although some device brands are shown here, it is solely for illustration. The authors are not endorsing a particular brand).

They focus on athletic performance and fine-tuned goals.  These trackers don’t have access to apps, like other wearables, but they are less expensive, don’t have to be recharged every day or two, and keep the wearer focused on the workout.  (Fitbit shown in photo)

The watches can track daily activity levels, monitor heart rate, and send notifications.  It used to be that running watches were the main choice for serious athletes, but the smartwatch is catching up.  (Samsung watch shown in photo)


running watchRunning watches allow the athlete to track pace information, heart rate information, cadence, and even detailed observations of running style. Most have GPS and some have mapping to track the route and altitude.  Running watches don’t have access to apps and music; instead they are dedicated to in-depth stats and other feedback for the serious runner.

Smart Scales

The following are examples of smart scales – basically fancy bathroom scales — which communicate information about a person’s weight and body composition to smartphones, as well as to sites that help a person manage their fitness goals. More information is available at

Withings – A scale with high-accuracy weight and body fat measurements, body mass index (BMI), and pulse. Data can be uploaded to the MyFitnessPal

Fitbit Aria – A scale that tracks and uploads weight, BMI, lean mass, and body fat percentage. It can sync with the user’s phone, as well as with Fitbit trackers and the Fitbit app.

ihealthiHealth – A scale that measures weight, body fat percentage, lean mass, body water, bone mass and more. Once the scale is connected to a home WiFi network, it communicates the data to the iHealth MyVitals app.

Personal Health Record

Personal health records enable patients to keep track of their health information using a hosted website or smartphone app.  Not only can patients keep all of their health information in one place, but they can share it with their doctors at scheduled appointments, or even with emergency responders in an emergency. More information about this can be found at the Mayo Clinic’s site.

Personal health records generally include:

  • The primary care doctor’s name and phone number
  • Allergies, including drug allergies
  • Medications, including dosages
  • Chronic health problems, such as high blood pressure
  • Major surgeries, with dates
  • Living will or advance directives
  • Family history
  • Immunization history

Consumers can also add information about what they are doing to prevent disease, such as:

  • Results of screening tests
  • Cholesterol level and blood pressure
  • Exercise and dietary habits
  • Health goals, such as stopping smoking or losing weight

Depending on the software or app used, a patient can also store PDFs of lab results or x-rays.

Personal Health Record sites:

Microsoft HealthVault lets the consumer gather, store, use and share health information for an individual or family. Apps compatible with the site help people stay motivated, analyze trends, and receive health education.  Personal health devices such as blood pressure monitors, blood glucose monitors and weight scales can interface with HealthVault.  The diagram below provides a pictorial representation of how each of the data sources interfaces with the app.



WebMD Personal Health Record is a free, standalone personal health record system with options for sharing information with doctors and others.

It doesn’t have a database of information itself, but rather it identifies organizations that do so the patient can log onto each site and access their health history.   The list of organizations participating in the service is expanding all the time, and currently includes some health insurance plans, hospitals or clinics, providers, pharmacies, labs and immunization registries.  Participants show the “Blue Button Connector” link on their website.

 Health Information from the Web

With the abundance of information available on the Internet, how should a consumer judge whether the information they are receiving is accurate?  Some questions to consider are as follows (drawn from

Is it up-to-date? Most web pages will indicate when they were last updated, and smartphone apps will show when the latest version was released.  When reading an article, any references to research should, in most cases, be from the last five years.  This is not always the case since some science goes back years, if not decades (i.e. basic care of cuts and bruises).  In either case the consumer should consider how current the information is.

Whose name is on it and who provides it? While some websites are sponsored by government agencies, non-profit organizations, or educational institutions, others are sponsored by private companies.  The user should keep in mind that the sponsor may have their own agenda and therefore may not objectively describe the topic.

Is the information accurate? Medicine is based on science, but some information on the Internet is not. The patient should consider sources carefully, especially if they point the reader toward a certain treatment option or product.
