Ten years ago, Jelle Reichert, founder of JOHAN Sports, ventured into uncharted territory with the very first version of the JOHAN GPS tracker for athletes: the V1 — a prototype that was far from perfect. However, one team, De Graafschap, under the guidance of head coach Jan Vreman, was willing to take on the challenge. Now, a decade later, both GPS technology and the use of data in sports have evolved significantly. In a twist of fate, Vreman is once again the head coach of De Graafschap, making this moment a fitting occasion to celebrate not only JOHAN Sports' 10-year anniversary but also a decade-long collaboration with De Graafschap.

Understanding the menstrual cycle is key to smarter training for female athletes. Johan Sports now integrates cycle tracking with GPS, heart rate, and RPE. Helping athletes log symptoms and adapt training to each phase. This leads to better performance, faster recovery, and fewer injuries.

The Johan Sports PACER system gives athletes the freedom to train solo, anytime, anywhere. Using the Live App, data is synced to the cloud, allowing coaches to monitor GPS and heart rate performance remotely. Ideal for camps, rehab, or off-season programs.

Cold weather significantly affects heart rate responses in football players. For teams using GPS and heart rate monitoring systems, it’s crucial to understand how lower temperatures influence cardiovascular load. In this article, we explain how cold conditions impact heart rate, what it means for interpreting training data, and how to adjust load monitoring for winter sessions.

Traditional team targets treat all players the same, but not every player has the same role or physical condition. In modern performance monitoring, using individual benchmarks allows for smarter coaching decisions and tailored development, especially when working with GPS and heart rate data. Discover how personalized targets can boost both team results and player well-being.

Perfect for coaches and analysts seeking actionable, data-driven guidance.

Heart Rate Variability (HRV) is a crucial tool for evaluating athlete recovery outside of training and matches. Unlike subjective measures, HRV provides an objective insight into recovery and stress levels by assessing the autonomic nervous system's balance. Regular HRV monitoring helps optimize training loads and improves overall performance by offering a precise measure of recovery and readiness.

JOHAN Sports extends the partnership between JES Soccer Performance. This will include Free Access to Soccer Fitness Courses and Masterclasses exclusively for JOHAN clients.

To confirm the JOHAN PACER's high accuracy and reliability in monitoring football performance, JOHAN Sports tested the PACER system against a LPM system during a training session. The results are shared in this blog.

We tested the JOHAN PACER system against the Polar H10 sensor during an Interval Shuttle Run Test (ISRT). The comparison aimed to evaluate the accuracy and reliability of these heart rate monitoring technologies.
