I am of the firm belief that for each athlete, training each individual biomotor quality that there is an individual stimulus threshold. By Stimulus Threshold I mean a point where the adaptive response diminishes rather than increases. Unfortunately I do have a way of quantifying this except by close observation and training results. In essence it is stressing optimum rather maximum. It is hitting the target, not too much, not too little.
And least we forgot it always must be in the context of the plan. This is very important when you consider the cumulative training effect. The sum of the adaptive response from a cycle of workouts is more than the actual number of workouts provided the stimulus threshold is considered. I have learned the hard way over the years that one workout can break an athlete, but one workout can make an athlete. As the Texas Tornados said “ a little bit is better than nada.” Less is more.
