HOW IS TUNE UNIQUE

Wearing TUNE is like turning on a mini-lab right under your feet. TUNE uniqueness is HOW  it collects and analyzes information from your runs through its sensors built directly into a pair of insoles.




HEEL STRIKE

Percentage of strides in which your feet contact the ground heel-first.

Why is this important for me?

Heel strike can be a result of overstriding, a common cause of injuries. Touching the ground heel-first can also reduce your speed.


STEP LENGTH

Average length of each step, calculated by dividing the total distance by the total number of steps.

Why is this important for me?

There are two ways to run faster: moving your legs at a higher cadence (higher number of steps per minute) or taking longer steps. If you are able to maintain a cadence above 150 steps per minute, it is possible to achieve both.


STANCE DYNAMICS

It’s an index that represents the ability to explore the ground underneath the foot in each step so as to move forward (propulsion).

Why is this important for me?

The higher your stance dynamics, the better you are using the ground underneath your feet to move yourself forward. Try to avoid excessive vertical oscillation (bouncing up motion) to fully benefit from improvements in stance dynamics.

CADENCE

Number of steps per minute. Recreational runners have a cadence between 150-190 steps/minute. The lower the cadence, the higher the risk of overstriding with potential harmful consequences.

Why is this important for me?

Optimal running cadence is considered the easiest way to improve your form, minimize risk of injuries, and improve overall performance. To avoid overstriding, you need to increase gradually your cadence (5 to 10% each time) and be able to maintain it above 150 steps per minute during a run.


STANCE TIME

Also known as Ground Contact Time (GCT), it’s the average time your foot is in contact with the ground during each step. Contact time decreases as cadence increases (and vice versa).

Why is this important for me?

Not all runners have the same ground contact time at the same speed or pace. Faster runners tend to have the shortest ground contact time, leading to faster force and applying the foot faster on the ground. Running ground contact time normally ranges between 160-300 milliseconds. With proper muscle training it is possible to improve your force and elasticity to improve your stance time.

HEEL TIME

Represents the time that just the heel is on the ground in each step. Shown in percentage of stance time (ground contact time).

Why is this important for me?

As a runner, if you spend more time with your heel than your forefoot on the ground it may cause overstriding. Overstriding, in turn, causes the foot to land too far in front of the knee and encourages heel striking, increasing your risk for injury. Training to propel forward can reduce your heel time. Good fitness, proper cadence, and training uphill and downhill helps improve your heel time.


GAIT CYCLE

Two successive placements of the same foot on the ground. Includes two phases: Stance (while the foot is in contact with the ground) and Swing (while the foot is in the air).

Why is this important for me?

The faster you run, the shorter your gait cycle and the lower the percentage of time spent in stance phase. This is due to spending less time on the ground and making good use of your propulsion force, making your runs more efficient.

TUNE uses GPS on your phone or watch to collect and analyze the following metrics during your runs.



PACE

Represents the rhythm of a run. Refers to the time it takes to cover each mile or kilometer.

DISTANCE

The length of a run, gathered from smartphone or smartwatch GPS. Programmable to be presented in miles or kilometers.

ELEVATION

Shows the variation of altitude during the run, gathered from smartphone or smartwatch GPS.

SPEED

Represents how quickly the running distance is covered and is calculated by dividing the distance by the duration. Programmable in the settings to be presented in miles or kilometers per hour.


AUDIO CUES

TUNE app includes audio cues for real-time information on runs and evolution (through ear buds). They are programmable in the app settings. The real time feedback contributes directly to being able to make immediate corrections to your technique.


SHOES

In case you use different shoes, the brand and model of the shoes used on each run can be registered to further analyze the effect of different shoes on TUNE metrics. This way, you have info and metrics for different shoes and can assess lifespan for each pair.
