Testimony of Julien Chorier (double winner of the Grand Raid de La Réunion, 4 times in the Top 8 of the UTMB)
Finally, a tool to objectivize quadriceps fatigue! I used the Myocene during the two months I spent preparing for my UTMB this year. Thanks to daily measurements taken before and after my training sessions, I was able to observe the amount of muscular fatigue produced by these training sessions and my speed of recovery from this fatigue. The good news was that the fatigue amplitude always remained within reasonable limits and recovery was always good, a sign that I had the right plan and that the preparation was going very well.

On the eve of a 2-week training camp in Val Thorens, a marked feeling of fatigue made me doubt whether I should take part or not. Perhaps a prolonged rest would have been more appropriate, even though we were very close to the UTMB and lack of training could be detrimental to my performance.. This type of problem has often occurred to me, and for the first time I had a way of making the right decision on an objective basis. So I took a Myocene measurement: the result showed that I had no peripheral fatigue, my muscles were at 100%, completely ready! So I decided to go ahead with the camp, which enabled me to achieve a time of 23:32, perfectly in line with my goal of under 24 hours! I also observed that the sessions during this camp had generated a little more fatigue than the rest of the preparation. However, the monitoring of my muscular fatigue level showed a very good recovery at the end of the camp.
All in all, the Myocene is particularly well suited to preparing for a competition such as the UTMB. The Myocene provides excellent support for load management in intense blocks, and for monitoring muscular fatigue generated by PPG sessions in athletes unaccustomed to them. On a routine basis, it also helps to clarify the situation and see if we’re on the right track, i.e. to confirm that there is little or no muscular fatigue over long sessions.
Legend: The measurements taken during preparation show that effort and recovery are well managed. It is interesting to note that, on day 27, the PPG session generates more fatigue than the other sessions. Similarly, the Val Thorens training camp, which starts on day 54, generates more fatigue than the rest of the training sessions, but recovery is very good thereafter (from day 59).
