Cycling: dicovering brand new horizons with Wimu and Moxy

Continuing with our multidisciplinary work with WIMU; last days we had the opportunity to work in an always exciting and challenging sport: cycling.


For this discipline, there are multiples parameters used for monitoring and follow up for both the cyclists and the bicycle. We are talking about: speed, heart rate, cadence, pedal power and…  muscle oxygen saturation (SmO2).
Those are just a few of the many available parameters.

Each parameter gives value information. It’s a practical tool for the athlete and his coach when they are facing training to improve the performance.  Never the less, it’s the fusion of all those parameters the real high value. When you can have synchronized metrics such as impacts, bike and cyclist inclination, rotation speeds, accelerations or oxygen consumption in each leg; is when you are dealing with High Performance and an authentic Smart Training.
This fusion of sensors (internals and externals) is what makes WIMU unique to plan and analysis the physical training.

Without any doubts, pedal power is a huge advance to train at the correct intensity in each moment. If you add muscle oxygen saturation, it’s possible not just to have the muscle work, but how that work is affecting it.

Training based on power allows to analysis quality of the workout; without taking in concern facts such as weather conditions or the field. Adding the SmO2, we can know how much it takes to full muscle exhaustion and recovery time.

Analysis of shocks on Mountain bike

The practice of mountain bike cycling is wide spreading increasingly as a leisure and free time activity. Currently more progress and development are being applied to this sport, looking for lightweight materials (stronger and less rigid), cyclist position (ergonomics) and shocks on the rider (front and rear suspensions).

In this situation we have used WIMU (two units) for shock intensity analysis over the rider simultaneously in 2 points (bicycle’s handlebar and rider’s body) on a stairs descent (the steps height is approximately 18 cm).

The importance of WIMU in this session relates to the study of the shocks over the bike, and analyses how the cyclist’s arms send the intensity of the impacts to his body (relates to the importance of using a good technique of arms and body).

On the other hand, WIMU allows us to see the functions of the front suspensions (it’s about 100 mm). We can see that when using suspension systems, there are no rebounds when facing impacts. This is a great improvement to the rider’s control.

Maximum intensity measured on the rider: 4.4 G
Maximum intensity measured on the bike: 6.6 G
