We have discovered the secrets of Jasmine Paolini and Yeman Crippa I am the Amazfit Active 2 sports smartwatch and the Amazfit Balance 2
When we watch professional athletes on TV, it’s easy to be amazed. How do they push themselves beyond what rankings or statistics predict? The truth is that the camera shows us only a tiny fraction of their world, just a few moments on the court or a short segment of the race. What we don’t see is what happens beneath the surface, inside their bodies. This is where modern wearable devices, such as smartwatches, come into play, tracking dozens of signals - from training load to recovery, sleep quality to mental readiness - all day, every day. With just one glance at these metrics, coaches and athletes can understand exactly where performance is heading. A recent tennis tournament in China with Jasmine Paolini is a perfect example.
Jasmine Paolini during tennis tournaments: the importance of wearable devices and Amazfit smartwatches
Jasmine Paolini uses the Amazfit Active 2 sports smartwatch to monitor her training and physical condition. A few days after the Chinese tournament, the Wuhan Open, she shared unique metrics recorded by her watch. Numbers don’t tell the whole story, of course, but they offer a new and interesting perspective on how her matches unfolded. The key parameters she shared include physical and mental fatigue levels (the Readiness Score) and heart rate variability (HRV), which indirectly reflects the recovery status of the nervous system. The rule is simple: the higher the Readiness and HRV, the more rested the body is, and the more quickly and efficiently the muscles respond. This is exactly where Paolini’s strength lies: on court, she moves and reacts with exceptional speed. In the first two rounds in Wuhan, Paolini showed remarkable determination and mental resilience, winning two consecutive three-set matches that really tested her endurance. According to Amazfit Active 2 data, her fatigue levels peaked midweek, precisely when she played those difficult matches, making her performance even more impressive.
Key parameters to keep under control
Before the first match, her morning HRV was 58 ms; before the second, 63 ms. On Tuesday (just before the opening match) her HRV had been higher, at 66 ms. The previous Sunday, Paolini had played and won the doubles final in Beijing, then traveled nearly 1,200 km to Wuhan. Her body may have felt the accumulated fatigue and travel stress midweek. Fortunately, she regained balance right when it mattered most. On Friday, she defeated a higher-ranked player 6–1, 6–2, reaching the semifinals. While commentators focused on her opponent’s unforced errors, Amazfit Active 2 data told a deeper story: Jasmine was in much better condition than she had been 24–48 hours earlier. Her Readiness Score hit 99, and her HRV rose to 67 ms. The next morning, her HRV climbed even higher (75 ms). This time, however, she had to acknowledge her opponent’s superiority. The semifinal was intense and played in extreme heat and humidity.
"People often see only what happens on the court, but performance is determined by so many small things behind the scenes. Traveling between tournaments and adapting to new conditions is part of the routine, and it’s what helps me grow as a player," Paolini explains. Experience and a disciplined routine help them manage these challenges, but there’s another crucial factor: the ability to read training and recovery data.
Marathon runner Yeman Crippa uses Amazfit Balance 2
Marathon runner Yeman Crippa trains every day with the Amazfit Balance 2. In addition to standard metrics, Yeman relies heavily on post-training and recovery data. This allows him to manage performance in two important ways: when necessary, he adapts his training based on how his body feels; and even when he changes nothing, he knows exactly what to expect from his body in specific sessions.
Amazfit is not only for professional athletes, but also for sports enthusiasts
And the best part? These benefits aren’t exclusive to professionals. Modern smartwatches like Amazfit Active 2 and Amazfit Balance 2 offer the same advantages to amateur athletes aiming for their personal best. Both devices track dozens of training, post-training and recovery metrics. These signals help us understand how our fitness is developing, how ready we are for the next session, and what to expect from our bodies. Will the day be a breakthrough or a struggle? Are we progressing or about to hit a wall? Thanks to data, performance is no longer a mystery. It’s something we can read, predict and shape in real time.
