In the power sector, the squat is recognized as the ultimate measure of strength, while leg strength is recognized as the measure of body size or strength of the mark. This is because the power of leg strength accounted for the largest proportion of the body, and the most practical.
Maximal Power Training (MPT) Vern Gambetta is well known to many readers as a coach, writer, founder of USATF’s Coaching Education, professional sports consultant, and even ex-editor of this esteemed periodical, among other things. When the call went out for articles, Vern responded immediately, and this piece is an excellent summary of the work of two Australian sports scientists, Greg Wilson and Robert Newton. In our opinion, Gambetta has always been on the cutting edge of training, and you will agree when you read this piece. For more information on what Gambetta is up to, his web site address is http://www.gambetta.com/main.html.

Currently, it comes out six times per year, but it will be bumped up to nine times in 1999. REPRINTED FROM TRACK COACH #145 (Fall 1998) The quest for the development of application.
