I’m interested to see if some have used heart rate measures as an indication of full recovery between sprint work? I understand that the CNS will take longer to recovery than metabolic recovery of course which is why, it would seem to me, it might not be such a great way to determine full recovery.
Tony Wells-the successful club coach from Colorado-advocates commencing with the next sprint when the HR is within a range of 108-114. I’d like to know how well such a range corresponds with what be consdered complete recovery by Charlie and others. The literature he pulled that information from was a Russian article from the early 90’s in Legaya Atletika by Jushko (I think) and another author I can’t recall right now.
Wells indicated that such a range usually has his girls running their next sprint in approx. 4-6 minutes for 30m and around 9 min. for 60m. To be sure, he has coached some of the best high school age female sprinters and hurdlers in the U.S. over the last 20 or so years.
I don’t know how accurate such a method is but if it were, it could certainly take some of the guesswork out of determining RI’s for different athlete’s sprint work.
