TruStrength Tech

Strength Gauge was developed by Texas Kiwi, in conjunction with AUT Professor Dr John Cronin, a world recognised leader in strength and conditioning. Strength Gauge utilises a mobile, wireless strain gauge technology to enable the generation of a reliable uniform set of force data for evaluating a user’s strength qualities while minimising risk to athletes and reducing the costs associated with more expensive technologies and injuries from maximal strength methods. This data is sent to a connected device to be analysed and displayed for coaches/trainers to better manage the implementation of their strength and conditioning regimes.

The Strength Gauge App can provide users and their coaches with real time actionable feedback that will inform them of a user’s maximal strength output, rate of force development and impulse. The APP provides time-stamped data, which lends itself to a great deal of flexibility in determining other variables of interest (shown below):
o Peak force – measures maximal strength of a movement at a certain time
o Rate of force development (RFD) – indicates the explosive force capability of users and we have the capability of identifying this over certain time periods e.g. RFD is important in reactive type tasks such as preventing falls
o Impulse (IMP) – is the amount of force generated in a certain time period and determines the velocity of an object

The Strength Gauge App includes a number of other features to allow the user to collect, organize, and compare a vast range of data.
o Ability to create multiple test profiles
o Ability to capture data and tag various isometric assessments including:
o Groin Squeeze Test
o Isometric Mid Thigh Pull
o Shoulder Internal and External Rotation
o Knee Extension
o Ability to view asymmetries (Left vs. Right)

The Strength Gauge App also enables the user to modify feedback during testing and how the data is processed post collection:
o Pre-Tension Threshold: ability to set a minimum threshold for the APP to
determine when a lift is tested
o Countdown: ability to include a visual countdown of when to begin applying
force
o Hold Duration: ability to include a visual countdown to tell the user how long to apply force for
o Force Goal Range: ability to include a visual feature on the live data stream to see exact force goals
o Ability to determine what time frame to assess RFD and IMP
