What would be the effect of splitting sets of exercises for one muscle group up throughout the day? For example do one set of an exercise in the morning, one at noon, and a third set in the evening? Would this be good for hypertrophy? Alternatively, would this technique be good for running(example:run 400m 10 times throughout the day)?
Andrew, it is important to remember the SAID principle. Your body will adapt to the demands that you impose upon it.
I think I understand why you are asking the question as a consequence of the questions you posed on blood pressure and the interaction we had regarding BP.
Just remember what the exercise response is to resistance training with the objective of hypertrophy. (Increase in systolic BP, avoid Valsava).
Too, years ago Wayne Westcott undertook some research on one set training and its benefits. I will look it up and get back with you. He really is knowledgeable as far as physiological adaptations to resistance training is concerned.
However, thanks for a great question.
