For elite and performance athletes, recovery is as important as training itself. A well-balanced autonomic nervous system (ANS) — particularly through strong parasympathetic activation — supports faster recovery, better performance, and reduced injury risk. Heart rate variability (HRV), and specifically the RMSSD component, is one of the most reliable ways to measure this recovery capacity.
A recent study led by Antonio Robustelli evaluated the effects of the NanoVi® Exo device on HRV in 20 performance athletes. After completing a standard training session, each athlete’s HRV was measured, then reassessed following either a 20-minute NanoVi® Exo session or a 20-minute passive rest. The RMSSD metric served as the primary measure of recovery, and results were analyzed using a two-tailed t-test.
The results were clear:
- HRV improved in 19 out of 20 athletes after using NanoVi® Exo.
- Average RMSSD increased by over 15%, with a quarter of athletes improving by at least 20%.
- The only athlete who did not improve had the highest baseline HRV in the group.
- The improvement was statistically significant (p = 0.0001).
The authors concluded that NanoVi® Exo effectively enhances parasympathetic activation and supports recovery in performance athletes. Integrating NanoVi® sessions between workouts or after intense exercise may help speed up recovery and optimize athletic performance.
