Smartphone apps help your fitness goals stay on track

 

Smartphone apps can monitor everything from blood pressure to calories consumed.

Blanca Famadas has discovered a new way to “stay faithful and true” in her decision to have a healthier life: her smartphone.

The teacher at St. Philip’s Episcopal School in Coral Gables has joined millions of people who are using smartphone apps to monitor everything — from exercise to blood pressure to blood sugar levels to the number of calories consumed.

“I have always walked a lot, from 45 minutes to an hour every day, but until now I never really knew how much,” Famadas says. “A colleague recommended the app Nike + Running. You download it to your cellphone and it keeps track exactly of how much you have walked and how long it has taken you.

“Knowing that motivates me to continue and allows me to know whether I have to speed up my pace or slow down to reach my daily three miles. I love knowing this and the best part is that the app does not interfere with you using your phone to talk or listen to music while you walk.”

Doctors, too, often recommend them for their patients.

“There are more than 100,000 apps related to health issues available through the operating systems of Apple, Android and Microsoft,” says Dr. Joseph Gutman, endocrinologist at Mount Sinai Medical Center in Miami Beach. “Not all are good or cover everything, but I encourage my patients to explore whatever is available because the best patient is an informed patient.”

The apps can be particularly good in tracking diet and exercise.

“I recommend them to people who have smartphones because several studies have demonstrated that keeping a log is crucial for losing weight and staying motivated to exercise,” says Sonia Angel, a nutrition specialist at Memorial Regional Hospital in Hollywood. “Before, we used to ask people to keep a journal and they had to have a pencil and paper all the time, which ended up becoming an excuse for not doing it.’’

A study by Northwestern University published in December 2012 by the Archives of Internal Medicine showed that a year after following 70 people with an average age of 58, those who used apps lost up to 15 pounds more than those who kept a log by hand.

In South Florida, preliminary results of a recent initiative sponsored by Florida Atlantic University’s Exercise Science and Health Promotion demonstrate that “those students who use apps are more enthusiastic and participate actively in the process of logging calories to lose weight,” said Natalie Díaz, one of the researchers of the project, led by Dr. Tina Penhollow.

Here are some apps recommended by users and medical experts:

•  Epocrates : Features a database of all available medications in the United States. The free version allows users to review possible contraindications and generic alternatives, identify pills and check out their interaction with up to 30 medications at the same time. There is also a $159 yearly subscription that provides specialized information about specific diseases, clinical studies and laboratory guidelines.

•  My Fitness Pal: Features a database with calories and nutritional values of more than two million foods and meals, from bananas to elaborate pasta dishes prepared by national restaurant chains. It allows users to log their weight, calculate the calories they must consume daily, and keep a log of food and of exercises performed. It also provides progress reports and allows sharing information with friends.

•  CalorieKing: Provides nutritional information for more than 70,000 foods and meals available in 260 restaurant chains in the United States. Novelties include comparing calories, carbohydrates and fat content of two meals.

•  Fooducate: By scanning barcodes of various foods it shows their nutritional values and other important data such as sodium, preservatives and fructose content. Based on these values, it assigns a category (A, B, C or D) and offers recommendations of similar but healthier options. It also allows users to keep a log of their food intake and the amount of exercise they perform daily. There is a free version, but the specialized options for patients with diabetes or gluten and other food allergies cost $3.99.

•  Lose It!: Users choose how much weight they want to lose and in how much time. Based on this information the program indicates the quantity of calories to consume every day and the level of exercise. It also allows sharing the information with friends so that they can follow each other’s progress.

•  MapMyRun: Uses the phone’s GPS to establish the distance users jog, as well as speed and calories consumed. It also allows sharing the details of the jog on social networks.

•  Nike + Running : Registers distances jogged, speed and time, informing users of statistics at every mile.

•  Sleep Cycle Alarm Clock: You place the phone with the app in a corner of the bed, preferable under the pillow, and after a week of “observation” it helps users identify sleep cycles and keeps a log of the hours slept.

•  HeartWise: Allows users to keep a log of their blood pressure with alerts to take certain medications or take measures. It also generates reports for doctors. It costs 99 cents.

•  Glucose Buddy: Allows patients with diabetes to keep a complete log of their glucose levels and of the activities affecting them from the time they wake up, including the level of exercise performed and meals eaten. It also incorporates other measures such as blood pressure and cardiac frequency, generating reports that can be emailed to doctors.

•  SoundAmpR: Allows use of your phone as a hearing device when connecting its headphones.

•  Water Your Body : Keeps a log of the amount of water consumed during the day, with special alerts to remind users when to drink more. It costs 99 cents.
