Description*** RunSafe personal running trainer***
Whether you are training for a 5k, 10k, marathon or ultra marathon, it is not only important to get out and run, it is very important to refine your running style to maximize your efficiency and minimize your chance of injury.
There are many running techniques, often contradictory, that claim to prevent injury such as barefoot running, chi running, POSE, midfoot strike, heel strike, forefoot strike. Independent of which running technique you choose, it is important to understand how your choice influences the stresses that your body receives. Running motions that produce a lot of start and stop activity will produce larger jerk forces which can affect injury rate and running efficiency.
The RunSafe personal running trainer app will record the amount of impact that your body takes while running, jogging, hiking or walking. Impact is determined by the average change in acceleration (known as the jerk force in physics) detected and is displayed as "Mean Impact". RunSafe will train you to run with lower impact through an audible alarm when your impact exceeds a user defined threshold. I have observed the following mean impact values:
Running w/ big stride, heel strike and slow cadence: 300
Running w/ midfoot strike and medium cadence: 220
Running w/ midfoot to forefoot strike and fast cadence: 125
Using RunSafe I have refined my running style to reduce mean impact and I am now running the longest distances I have run injury free for the first time. I can also conclude that running styles that reduce impact also improve running efficiency. As a result of lower impact running, I improved my previous best 5k pace from 10 min/mile to 8.5 min/mile in the course of a week simply from adjusting my running style to minimize impact.

-- Audible alarm when average impact exceeds target
-- Stopwatch like controls (start/stop/reset)
-- Create splits on demand
-- Automatic splits created based on time
-- Share results on twitter (#RunSafe)
-- Save all summary and splits data through email

For best results you should have your phone firmly attached around your waist.
So, if you are experiencing running injuries then try training yourself to run lighter by monitoring the impact of your running style. Track your impact values over time and adjust your style. Whether your injuries are related to your foot, calf, knee, hip, or back, reducing impact could help.

This app uses the accelerometer on your phone. Many phones will incorrectly disable the accelerometer when the display is turned off. While the app is actively collecting data it will disable screen shutoff. Additionally you should NOT put your phone in sleep mode by pressing the sleep button. As long as the screen is on (okay to be dimmed) then the accelerometer will work fine. Some phones work properly with the screen off. If this is your case you can allow your screen to shut off through the app settings
