Pauline Ferrand-Prevent's back accessory during the Tour de France Femmes—what was it exactly?
The cycling world is witnessing a significant shift with the introduction of the Tymewear VitalPro, a heart rate monitor strap equipped with additional breathing, motion, and elevation sensors. This multi-sensor system, worn on the chest, is currently being utilised by the Visma-Lease a Bike women's cycling team, including Pauline Ferrand-Prevot, who recently clinched a historic victory at the Tour de France Femmes [6].
The VitalPro sensor's circular sensor, discreetly visible under riders' skinsuits, measures chest expansion and contraction to calculate key metrics such as breathing rate, tidal volume (air intake per breath), and minute ventilation (total air moved in and out per minute) [1][3]. These metrics offer valuable insights into the internal workings of the body, reflecting the transition between aerobic and anaerobic metabolism.
By detecting metabolic thresholds through breathing rate and ventilation, the Tymewear system enables the creation of more accurate and effective training zones [3]. This innovation surpasses traditional heart rate-based zones, leading to improved training effectiveness and performance management.
The sensor's data seamlessly integrates with Garmin devices for real-time monitoring during rides, and through an app, athletes can perform threshold tests and set ventilatory threshold targets for ventilation, breathing rate, heart rate, power, and speed [1][3][5]. This allows for the tailoring of training intensity according to physiological responses rather than relying solely on power or heart rate data.
The UCI has approved this transformational breathing sensor technology for use in competition, highlighting its potential to provide a gold standard measure of metabolic output during races [2][4]. The Visma-Lease a Bike team, known for being at the forefront of cycling technology, is one of the pro teams that may be using Tymewear threshold zones in training [7].
For those interested in the Tymewear system, the VitalPro strap can be purchased for €299, or with a training membership at $150 per year [8]. As wearables continue to fill in more gaps around physiology, nutrition, and training, the Tymewear sensor marks a significant advancement in endurance training and race monitoring.
For further reading, the Tymewear website includes an interesting validation study [1]. The controversy surrounding the Superspiens glucose monitoring system, which led to Kristen Faulkner being stripped of her Strade Bianche podium, serves as a contrasting example in the realm of wearable technology in cycling [4].
