In the picture above i’ve displayed muscle oxygen saturation (SmO2) workout data from one of my athletes performing the same exact workout on two different days, separated from one another by three weeks. The specific workout they performed was as follows:
400m Run @76-78 seconds per set; Rest 30 seconds x8 Sets *These repeats were done at around this individual’s 3200m PR-pace.
In the interim period between the first and second time this athlete performed the workout we prioritized (1) respiratory muscle endurance training and (2) general cardiac output development with the end goal being to improve their speed-endurance and improve their 3,200m run time. The reason we prioritized (1) and (2) so heavily is that this athlete needs to improve their cardiovascular control. Since this individual is diverting such a high percentage of their cardiac output to their respiratory muscles (to support extended hyperventilation) the simplest way to improve cardiovascular control is to increase th…
