This is related to something that I was thinking about in response to some of the (anonymous) comments on the post the other day about interval training. If you can get the same effects from intervals as from long duration exercise (and that is how I read this reseach ) then why spend the extra time on the endurance training?
You need to do enough, but not more. More means more chance of injury. More means more recovery time.
It seems we all preach more is not better but then when it comes down to it we end doing more. As my good friend and colleague Gary Winckler so succinctly states “volume is not a biomotor quality.” I think there must be some comfort in doing more. What we need to focus on instead is the concept of the stimulus threshold. I define that as is the threshold amount of work that is the optimum amount to elicit a training response. If I can continually train at the threshold and push that threshold then I should be able to make continual adaptation. What good does it do to exceed the stimulus threshold and not be able to recover to do a subsequent session? Another way to describe this is to determine a training target in the context of the whole training plan and hit the target. I think part of the problem is that many people are unsure how to determine the target so they do more to cover themselves. We should be able to workout the stimulus thresholds for various qualities based on the training age of the athlete and their competition objectives. It is certainly not an arbitrary figure like 100 miles a week for a runner or x number of thousand yards for a swimmer; rather it is the actual breakdown and composition of the sessions with a distribution among the performance factors in the context of the training plan. Certainly it is necessary to overload, but remember that it is possible to overload by manipulating volume, intensity and density. Manipulating the means of overload will insure a positive adaptive response.
Perhaps another way to express this concept is to seek optimum training loads rather than maximum training loads.
What do you think?
