The “5-Star System”. Comprehensive Running Form Analysis. Simplified.

Defining a good running form is not Rocket Science, but it’s still extremely subjective. However, most experts agree that good running form is key to better performance and an injury-free running experience. And they also agree that the five fundamental vectors – Cadence, Ground Contact Time, Foot Strike, Body Balance and Impact Stress – form the key to good running form.

Stridalyzer Smart Devices, coupled with Stridalyzer Analytics and guidance solutions, is the ONLY solution that measures, analyzes and provides you an insight into all these vectors, and provides a proprietary rating system, that we call the “5-Star System“. This system was developed with feedback and guidance from veteran runners, coaches, trainers, sports physiotherapists and orthopedic doctors.

When you run with Stridalyzer Insoles or PODs, at the end of every run, Stridalyzer App works with the cloud-based Analytics system to analyze your entire run for the 5 areas, and provides a rating to each area:Activity_summary_iOS_alt

  • Cadence: Are you taking the recommended number of steps per minute – about 160-180?
  • Ground Contact Time: The lower your GCT, the better, as that means you are utilizing the knee & hip spring action optimally.
  • Foot Strike & Stance: While heel strike in itself is not a big problem, if your heel strike tends to cause you to overstride, that’s a concern.
  • Body Balance: Stridalyzer detects the load distribution on each leg, and calculates the avg. distribution throughout the run. Needless to say, a disbalanced loading will increase injury risk on the leg that’s overloaded.
  • Impact Stress: Stridalyzer senses and measures impact stress through out your run. A uniformly distributed stress pattern ensures no part of the leg is taking undue burden, as excessive loading on any one area increases injury risk significantly.

If you score a rating of 4 and above – you’re doing good! Otherwise, you might want to look into our guidance and recommendation for fixing some of the issues!
