James- I have a few points for your consideration. 1. You did not specifically talk about the relative contribution of the anaerobic system and the extent to which it can, as a system, be improved to deliver more energy (as opposed to enhancing tolerance, buffering capacity etc) 2. Sprint intervals obviously involve the anaerobic system but you only looked at the training effect via mitochondrial function and oxygen re saturation. 3. The sprint protocols were very wide with no elaboration on the specific effects of 6 second intervals v 30 second intervals or the vastly different protocol of a 1:2 work/rest ratio v a 1:8 ratio. 4. There was no discussion of transferability of modality. I would be cautious to assert a carry over between a lower body training modality and an upper body dominant sport. Time to fatigue improvement in a specific activity may result simply from better efficiency and tolerance and have next to no carry over to an entirely different activity.
Love your input Peter. I covered a bit of your first 2 points in a previous video I believe on lactate. I wanted to convey how high-intensity training isn't an anaerobic activity as it's believed to be. And we cant look at exercise as aerobic vs anaerobic since O2 is used and lactate produced at all intensities. Good point on the practical recommendations, I went in more detail in an older video but just provided general guidelines here and yes, efficiency is everything which is why I mentioned at the end about practicing your sport enough etc. Also mentioned you can use a grinder for upper body. Or can just use an airbike for example
I should add doing these videos is helping me piece all this info together in my head so I'm sure there's a lot I'm missing and will be iterated over time 😅
@@sweetscienceoffighting James- if I may, let me try to push you on one physiological issue which I mentioned and find troublesome and that is use of the terms anaerobic capacity and power which I take to mean producing more ATP via glycolysis and producing it more quickly. I can find no confirmation that such exists or how improvements can be measured other than indirectly by, for example, time to fatigue which can of course be due to other factors. Is this something you may have considered?
It's one of the issues I have with the traditional energy system model as the terminology doesn't make sense. Regarding increasing ATP production through that pathway directly I'll have to do some digging
Nice work. Thanks for flagging that paper "Use of NIRS to explore skeletal muscle oxygenation.... " that looks like an interesting read. I am interested in inter-round recovery in both sparring and padwork as my karate system has a grading with a standard of 20x3 min rounds of essentially kickboxing with 12 padwork then 8 sparring rounds on a 45 second 'rest'. I noted the graph showed in sparring the 6th round had a way lower start compared to bagwork or padwork, but yet the metrics showed so many less strikes were thrown in sparring.
Yea that's one of the implications from that study showing pad or bag work likely isn't suitable for fight preparation for conditioning unless modified
@@sweetscienceoffighting - yeah, I think it comes down to showing neither are singular cure-alls for fight prep, but rather all are parts of the overall jigsaw puzzle, along with other components, like the sprint intervals, and the zone 2. The trick is to having the right number of the right pieces to solve your athletes version of the puzzle.
What if you have a vo2 max between 40-50? Would you focus more on bumping it up? UFC PI data suggests many of their top fighters have a vo2 max over 60.
Yep if your VO2max is low then basically anything is going to improve it. It'd be more about training more often or adding a couple of long or short HIIT sessions. Zone 2 is another option but takes a lot of time

Last longer between rounds
