Thanks, Tim. My first experience with isometric tension was a small booklet I received at age ten, from Charles Atlas. As far as weight training goes, we used to do cheater reps at the YMCA during the late 60's, which is not quite the same. I suppose static contaction is like holding the position you would stop at during a cheater rep, say for 15 seconds. I tried this at the gym today with a variety of compound exercises, finding a point of maximum contraction and holding it there for 15 seconds after eight full reps and the third set. What got me into investigating this topic was a book I thumbed through entitled, Static Contaction, by Peter Sisco and John R. Little. He makes some pretty wild claims and backed them up with real scientific studies using veteran weight lifters who were over age 35. They made some significant gains in muscle mass by using the workout programs featured in the text. What really struck me as odd (and went against my old school-grain) was the text's analysis of full-range motions as coming up very short on peak contraction time. Whereas, the authors propose starting a set at that exact position, where the most muscle fibers are brought into play and holding it there, counting seconds, not reps. That's why I thought this would ultimately lead to tendon and joint problems, and why I thought incorporating this into a set of full-range motions would be better. At my age, I am battling to build new muscle fibers as fast as father time wears down my old ones. Again, thanks for your reply, Tim. I hope to hear from other forum members on this subject, too.
