This is my issue with ARP for sprinting (I think it works well for team sports). I’m not sure how you combine it optimally with sprint training at the levels required to make an Olympic final. The contact times are so short and the power output so high that I cannot envisage training like Schroeder suggests when you are hitting 12m/s. However of course I would like to decrease the recovery time needed and achieve a greater number of very high quality sessions (increased density) in a year as this is what allows the learning to occur for the best performances.
