I personally like the occasional use of Intensive tempo, but overuse leads to injury its a fine edge of beneficial and danger with this 🙁
What are everyones thoughts on Contrast training and Post Activation Potentiation for acceleration development.
We know Bolt, Blake and Asafa’s coaches have them doing a lot of sled and hill training (much more and heavier then that usually advised or coached here in the UK)
I personally love contrast training, both in the gym and on the track. Most athletes/coaches I have read or spoken to really like it and believe it adds something to the mix. I also think its a great way to make improvements in acceleration in a short time. I think its partly about hitting many parts of the force-time curve, and partly about potentiation effects. Some believe you need to be careful as it can be extremely taxing on the athlete, but I haven’t really observed any such issues myself.
I hear what you’re saying about the heavier than normal sleds and steeper than normal hills. I think the 10% rule is very important when you’re training the later stages of acceleration and doing what you might call “resisted Max V” work, but I don’t really see the logic in limiting yourself to the 10% rule when training early stage acceleration.
