Basic metrics

For these basic metrics, you don't even need the ARION wearable. Just download the free app from the App Store or Google Play and start logging your running sessions with the following metrics:

  • Pace (or speed)
  • Distance
  • Duration
  • Mapping
  • Altitude

Advanced metrics

The following metrics will be available to you with the ARION wearable. 

Footstrike

Footstrike indicates where on the foot initial contact is made as it is placed on the ground. Typically runners are categorized into forefoot, midfoot and rearfoot runners. This type of information can be important to understand what injuries you might be at higher risk of incurring and, for certain types of running, can influence performance. 

Cadence

Cadence is a measure of how often your feet touch the ground each minute. It is a critical part of running influencing the loading on the body and your overall performance. Elite runners commenly adopt a higher cadence suggesting that this can be an important element of running economy.

Step length 

Step length is a measure of how big the steps you take are. It differs depending on your length and influences the angle your feet hit the ground. Step length has an influence on your running performance, efficiency, the loading you experience with each step and may affect the risk of injury.

Balance 

Balance indicates how symmetrically the feet are used. When one foot is used substantially more than the other, for the average body type and during normal running conditions, it may be a sign that there is an underlying injury, restriction to the range of motion or imbalance in the musculature. 

Stability

Stability is an indication of how consistently the foot is placed on the ground during running or walking. Someone who places their foot very differently with every step they take will have a low stability, whereas someone who always places their foot on the ground in the same way will have a much higher stability. This can help you to understand whether you are at an increased risk of injury, and help you to select the right shoes for you. 

Contact time

Contact time refers to the time that the foot remains in contact with the ground during each step. Research has indicated that for any given speed, shorter contact times often correlate with better running efficiencies. Many elements of running technique can influence contact time, but however it is achieved it can be an indicator of how you are progressing.

Flight time

This is the amount of time both feet are off the ground. During running there is a phase of the gait cycle when both are airborne whereas during walking you will have a flight time of zero. It is affected by parameters such as step length, cadence and vertical oscillation.

Heart rate 

Heart rate is, rather simply put, the measure of how fast your heart is pumping. It is a good indicator of how hard you are working. Heart rate training zones are commonly used to influence the source of energy your body will utilize (e.g. the ratio of energy sourced from fat, carbohydrate and protein) and whether you are working aerobically or anaerobically (i.e. whether you are running on oxygen or whether you are accumulating lactic acid). It can also be important for regulating interval training, pacing yourself during distance running and understanding your fitness and capacity for exercise.
