# Where does the sensor go?
# What are your options for analyzing the results?
# Can you see the data in real time? This makes a huge difference if you're trying to improve your biomechanics. Ideally "Watch" means you want the have real time information so on a the watchwhich is one of the ideal approaches. "Phone" means you get real time data shown on the phone display, which if it's done right can show an awful lot of data. "Audio Coaching" means you get periodic audio messages which I find more annoying than useful. "RTAF" is easy to carryReal Time Audio Feedback, which means that your hearing an indication that you're past a threshold. Having to not only carry a phone but look at For example, the display [[TgForce]] will be if your impact is something I dislikehigher than a given threshold, and it will be part of every footstep.
# Do you have to carry your phone with you? I hate carrying a cell phone when running, so this is a factor for me.
# Phone needed to get anything beyond HRM.
# You can use two pods and compare the data, but the system won't compare the results for you.
# [[Impact ]] can be measured in various places, such as the foot impact, the lower leg (tibia), or the chest. The impact can be measured as peak acceleration (g's) or as rate of change of acceleration (AKA "Jerk").
# This is Rate of Impact, which is slightly different to simple impact g's (see review for a few more details).
# The $200 kit only comes with one sensor, so you'd need to by a second.
# This is the rate of change of acceleration (AKA "Jerk") in three separate axis: up/down, side-to-side, and left/right.
# A sensor that doesn't allow for data export locks you into the vendor's tools.
# A 9-axis sensor can detect twisting motions through its gyroscope, in addition to the acceleration measurement of a 3-axis sensor. # Measuring Vertical Oscillation from a footpod is a dubious proposition and the results seem unsurprisingly poor.
