In my current study, I analyzed AIDA and CMAS competition data to present comprehensive descriptive statistics on freediving disciplines for the first time. I think even the pure distributions are interesting for many divers, as they allow a relatively fair and comprehensive comparison. These values are now available for the three disciplines STA, DYN and CWT. This can be used, for example, to show how good your own results are compared to the population. It should be noted, of course, that freediving is not about better or worse and that safety and fun are the most important personal factors. These analyses should therefore be seen as complementary to the previous AIDA “rankings”.
Furthermore, comprehensive correlations and predictions of the three disciplines are now available. These analyses are very useful for identifying your own strengths and deficits, for example, questions such as: I have a STA time of 3 minutes, what DYN can I expect? can be answered in this way. It should be emphasized that these are average values and deviations are natural.
Finally, I also looked at gender effects. It is interesting to note that these differences are very small, especially in the middle and lower performance range. The results also show that only a very small proportion of the differences in the results can be attributed to gender. All descriptive results are available separately by gender for more information.
