Quite often we are asked the same question: how does Checkmylevel differ from Heart-Rate Variability (HRV)? It’s a good question since there are significant differences.

The similarity is that both methods provide data about recovery status and how one should optimize training. Also both systems are giving information about training readiness of an athlete and also recommendations for training intensity. Big difference is that HRV measures the CNS (central nervous system) whereas Checkmylevel measures data via PNS (peripheral nervous system). In combat sports, PNS provides more real-time and accurate feedback.

Check the following chart to find out how this plays out.

HRV vs. Checkmylevel

The picture above represents data from a male combat fighter. He was preparing for a tournament and collected readiness data 80 days before the contest by using both HRV and Checkmylevel assessments. The red graph displays HRV data and the green data is collected with Checkmylevel system.

The scale used by both systems was similar and all results shown were from a 0-100 rangeThe Readiness -value indicates the recovery level of the athlete: e.g. a high score means that the athlete is fully recovered whereas a very low score means that the athlete is exhausted and not recovered at all. Both assessments were done in the morning before a workout sessions.

It seems that both data sets follow more or less the same trends. However, an interesting remark is that even though the athlete was having a very intense training period, the variation with HRV measurement is quite low. All the HRV measurement were within the range 70-90 which indicates a medium-to-high recovery.

This doesn’t reflect reality very well since the athlete was doing some very high-intensity training sessions during the period and had some mixed feelings about high readiness scores given by HRV. For some reason, HRV suggests that these high-intensity sessions were not affecting the overall readiness and thus recommended the athlete to keep on training. This was in conflict with the athlete's own feeling as well as with data collected by Checkmylevel.

Checkmylevel was showing a lot greater variation in terms of readiness. As you can see, the highest readiness value was 100 and the lowest 20. According to the athlete Checkmylevel was able to show readiness changes that were also consistent with his own feelings especially after high-intensity training sessions. Many of these sessions involved speed, skill and coordination -type of training and was focusing on explosive strength qualities instead of endurance.

Of course this is just a data chart from one athlete. But the interesting finding is that even though these two methods seems to follow the same trend, there are significant differences in the way HRV and Checkmylevel interprets the effect of explosive power training sessions of high-intensity. After interviewing the athlete he was in favor of Checkmylevel results in having a stronger correlation with his own feelings.
