How to Use a Heavy Sled to Build a Sprinter

Our guest for today’s show is Randy Huntington.  Randy is a track and field coach, who has spent his recent years as the national track and field coach for the Chinese athletics association and has over 45 years of coaching experience.  Huntington is rated as a USATF Master Coach in the jumps, has been the coach for many world-class athletes over the years, including eight Olympians and seven World Championship Team members.  Mike Powell and Willie Banks set world records in the long jump and triple jump, respectively, while under his tutelage. More recently, Randy has had tremendous success coaching in Asia, a capstone of which has been Su Bingtian, who recently set the Asian 100m dash record of 9.83 seconds at age 31.  En route to his 100m record, Su broke the world record in the 60m (as a split time) with a 6.29, which converts to around a 4.07s 40 yard dash. When a teenager, or relatively untrained individual takes a few tenths off of their 40 yard dash, or drops a half second in the 100m dash over several years time, this is a normal and natural occurrence, and isn’t something that really demands digging far into.  On the other hand, when an already elite athlete, who is at, or slightly past their “prime” years, moves into their 30s and smashes sprint records, this is something that is truly worth putting a close eye on. On the show today, Randy Huntington speaks on some of the training elements that helped sprinter, Su Bingtian achieve his recent results.  Randy goes into his views on special strength training for speed, particularly on the level of the lower leg, and speaks on the use of banded and wearable resistance in speed training, as well as some nuts and bolts on resisted and sled sprint work.  On the back end of the show, Randy gets into training the elastic and fascial systems of an athlete, and how to optimize an athlete’s elastic response to training in plyometrics and beyond.
