About NASE

Learn about the establishment of NASE, what we do, and how we became the world’s leading authority on speed improvement.

Membership in the NASE is a DIFFERENCE MAKER for your high school program! Every issue of the Sports Speed Bulletin contains information that will make your program better! If you have any questions or concerns about speed training, Dr. Dintiman and the NASE staff is readily available to assist you! I think it is the BEST national certification on the market and the best return on your time and money.

The online speed and explosion certification course is the only speed certification today that I have truly obtained useful information for teaching my athletes how to become faster. As a former Olympian, this certification has helped my staff and I reach higher levels in coaching, this is by far the best certification I have ever taken as a coach!

Backed by time-tested science and experienced coaches, NASE provides the most practical and useful information to equip any coach at any level to improve their team’s speed.

The NASE certification program has taken our track team to a new level of performance. In the past several years, using the information I have gained through the NASE, our team has won 4 state championships, had two national champions, and 9 high school all-americans. I am absolutely convinced this is the premier speed certification in the country.

The NASE puts you in touch with what your athletes need: playing speed and explosion. Many thanks to Dr. Dintiman for his continued effort to promote our field.

The NASE is the best speed training certification in the country. The certifications of our three trainers has greatly improved our sports Enhancement Program designed to help young athletes prepare for college and H. S. athletics.

The NASE is the single best association in the U.S. for coaches, athletes, and other professionals at all levels.
