But energy system wise is the aerobic contribution in the 6X300m @42s with 90s recovery sesion listed not significantly greater than that of a 100m race?
For example take two 10.00 sec pb athletes: Athlete one’s training is influenced and as able to complete the session within the relm of extensive tempo. Athlete two’s training is not influenced and has to work at intensive tempo levels to complete it.
You could look at it from a time perspective and and say 6X(42second runs) but athlete A will still have an inherent advantage as soon as demands begin to be placed upon the aerobic system.
The main thing I think everyone should take away is from this is from your last statement, even to this day most people do not acomadate their training to themselves.
