Pfaff also noted new research on short burst activity and applications for aerobic adaptation quality and even lactic acid tolerance. A block start ladder ??? 4-5 x 10m, 20m, 30m, 40m – yields
portable blood lactate values over 16mml. without running over 40 meters! There is a more specific way to train lactate work and keep on the track for short sprint work!
As mentioned before in an earlier thread (https://elitetrack.com/index.php?option=com_smf&Itemid=94&topic=114.msg26942#msg26942) I believe this workout is very beneficial and a key in developing sprinters. I believe Quik or JJ pointing out that the Italians used similiar work in 70's and 80's. I learned this workout while in military in the early 90's from a former sprinter whose time in the military could have subjected to him to these italian influences in his training.
One concern that I have come by thru research is that the introduction of lactate work can interfere with the motor learning process. Therefore before this workout should be done, the required skill set inventory for a sprinter should be near completely taught. Meaning that acceleration mechanics should be above average before you ever use this type of workout. Just by chance in my own coaching experiences I have had this workout come later in the season, now I can introduce it earlier to the athletes who have the skills to execute properly during it, and may even not introduce it to those that are beginners now that I have a better understanding.
