First of all, thanks for the many emails asking whether I gave up the forum discussions as many seems to use some of our ideas from the forum .
No we did not stopped the forum. It was juts me having to regroup and rethink many great discussions I had the fortune to enjoy during our week in San Diego at the ACSM . So we will be back with many great feed backs and critical ideas. I like as so often give some thoughts on what my personal biased experience is or was after over 20 years of visiting a meeting, where an incredible amount of Brain power is available.. It is as well really interesting to see, how ideas and directions can get influenced by individual names but as well by new directions. First what has changed. a) the 20 years back situation, where ACSM is the temple and the gospel we hear there is what is the truth and only that is the truth has very extremely changed. There is very little truth anymore available as we have a much more open debate now on all different directions in sport science. Anything is now much more open discussed. Nobody really defends anymore with all force the idea of VO2 max testing as the golden standard. People actually in most presentations as well as in nearly all of the hundreds of posters avoid using VO2 max and replace it with VO2 peak tested . 20 plus years ago lactate threshold was the real truth and now there was actually one single poster in hundreds of postures , who tried to somehow justify the existence of a LT and it was interestingly enough a German presentation. In a personal discussion with the great person behind the poster , the discussion very fast showed, that he himself had some major problems to defend what he had on the posture as conclusions. Many many poster started to look at energy demand and delivery and as such there was an incredible increase in studies presented, where NIRS is used. Great ideas and great questions where presented and the clear indication in many of the presentations was. We are just at the start of a new direction in physiological bio feedback ideas. The expo showed how the technology is moving ahead no matter, whether the scientific world is able to follow this fast pace. This changed the whole dynamic in the EXPO itself. I never had so many people stopping by a booth and actually asking questions and would stay a long time at the booth. We had great people from great universities visiting MOXY and where ready to come back and would discuss and look at the ideas over 30 plus minutes up to 1 hour. We had people bringing in files from test they do for studies and asked for interpretations. . Nirs won the fun competition in T. shirts for noninvasive ideas. Another huge change is sport specificity. There is very little discussion anymore. but nearly all agree, that a VO2 " max " test on a game sport athletes is of minimal to any value other than data collection for a presentation. The idea to assess on the field during a race and using the same equipment for assessment and for training control is the future. Main problem is for many still on how to apply it. Many struggle with the fact, that old ideas may have to be reviewed and justification for classical principles may have to be rewritten. Ideas like how to justify cool down or warm up, ideas like tolerance training and whether anaerobic is really anaerobe, ideas like periodisation based on weeks and month and days versus periodisation based on physiological reactions. Much more to talk about but to come to an end here. One of the last presentations form a key not speaker was an incredible great reminder on what we often forget. In very very short words. what he tried to get over to the many people. :If you do NOT know the history you will repeat many great studies to find the same information all over again and you as well will repeat the same mistakes we all did and still do since generations. He has some great examples from studies done in the 1920 - 30 which are forgotten and are repeated now all over again. Some use the same ideas and repeat the same mistakes and some use newer ideas to find the same outcome.His final conclusion really was to avoid trying to justify what we use as a common idea when applying new technology into the world and let the new technology critically open questions we need to ask us n our old ideas. The most impressive situations I had, when talking to some of the older generation, the big brains in sport science, which now do not need anymore to defend themselves . They all agree, that there has to be a much more openness to new directions and that the classical concepts have to be reviewed including many they set up. . So the outcome is that many of the great brains tell us, that they do now accept that they do not know a lot anymore. The scary part on the other side is that many young " researcher" and let's name them "kids' seem to know everything and defend hat they just learned. and have minimal information on the history on what they try to learn. . Hmmm reminds me on myself , when looking back and in the mirror. As longer I work in this field as less do I really know but as more interesting questions we can ask. Looking 30 - 40 years back and I had all the answers..It was easy I had all the knowledge, I had all the proper answer and now I have very few answers ,but many many more questions. As such we will be back on the forum asking more questions and having limited ideas or answers but rather new directions.. I am looking forward to the next few month and years in the explosion of more practical applications. As well I look forward to the ongoing discussion on physiological reactions versus physical performance. So stay tuned as I try to show up again regular on here. If I am somewhere behind in trying to give a feedback on ideas please remind me and I will try to pick up where I left. Last but not least , Thanks to Jiri for his incredible great poster and presentation in San Diego. Jiri Dostal is the most likely most advanced NIRS user and has a data collection in the over 1000 range and had the first real big data presentation on the ASCM. See pic.

Nice discussion and presentation. I don't know if you used it for your analysis, but time series clustering is a technique which you can use for this type of data
