I believe you can still get supertraining through perform better, I think. If not i am sure someone on this site will know how to get it. Its a tough read but well worth it.
Science of sports Training was written by Thomas Kurts. Its a decent book, I had a to read it a few times to understand it. The author writes in a different way bu the info is not over the top. Its a book I enjoyed. You can get it here:
I’ve got the second edition of the book. It does a good job of reviewing the basics of the physics of human movement, then goes into detail on the workings of the neuromuscular system, and acute and chronic training adaptations. Its worth picking up if you have the time to read through it all.
Supertraining is on the www.elitefts.com site; however, the shipping costs act as big deterrant not to get the book. The price of the book itself is alright though 70.30 CDN. With the shipping it comes out to nearly 100 CDN 91 CDN I believe; however, if you order 2 books then the additional shipping cost is only an extra 2 dollars american and the more books you order the shipping cost becomes irrelevant.
