Here is an incredible summary from Yvon and some may remember the part , where we compared lactate with "stress" resp, endorphine release and how it goes up together, and that it needs a certain time and intensity to create this reactions.
Well read this info here and you see, that we a have on Yvon a jewel in our group with incredible knowledge and input, which makes not just sense , but keeps as honest and thinking and puts many "cookbook" ideas on the back burner. Thanks a lot Yvon and I like to share this with our regular Forum readers, as it opens the doors wide for more discussions and ideas.
I keep reading all your forums and specially the one on the Lactate; so let me express some comment on this issue. From a neuropsychological perspective Lactate is at the same time a source of anxiety and more and more indication lead to believe that it is also the result of it. One thing is thus sure: from a neuropsychological perspective Lactate and anxiety are somehow link together.
Knowing that we can then reasonably assume that the psychological reaction to Lactate must have the same pattern as the reaction to anxiety (to stress) which mean that we should not be looking for a universal threshold point but rather to an idiosyncratic one; as it is the case for stress, I suggest that the right level of lactate (the one required for optimal performance) should depend at the same time on the physiological characteristic of the person and on the characteristic of the activity perform.
We cannot denied that the increase in Lactate is not linear but it is the same with stress were you find rather and inverse “u” pattern (∩) – for each person and for each situation there is a point were the stress in relation to performance maximal and that range is very narrow – so you have a lot more probability of maintaining not enough or too much stress. That is why it is often difficult to find the right range of stress needed. But this model emphases the fact that there can not be such a think as a “universal threshold of stress”.
Moreover, knowing the effect of the Lactate on the physiological systems, I suggest that we should investigate the means the adjust, in parallel, “stress” and “Lactate” level – ideally what we surely want is that these two reach their maximal efficiency level at the same intensity. I am sure that practice can achieve that over time but their may be a way to help the CGS to realize this apprenticeship.
