Guest guest Posted December 29, 2001 Report Share Posted December 29, 2001 They probably mean the 1-6 method where you do a 1 RM followed by a 6 RM and you repeat. If I remember correctly, the theory is that after the 1 RM, you will be able to do greater 6 RM weight. As Dr Siff said, a sinusoid is just the sine function under any linear transformation. I think the only thing it has to do with this terminology is that it goes UUUP and dooown. LOL [No, this is not at all what Dr Basmajian meant. In his book, " Muscles Alive " , he referred to sinusoidally varying mechanical pulses imposed in the laboratory upon ordinary, non lifting subjects at a frequency of 5Hz, as I explained in my earlier letter. The theory to which you are referring is known as " post-tetanic " or " post-activity " facilitation and is also described in " Supertraining " . The latter process and sinusodial vibration are two different methods of neuromuscular facilitation.

Guest guest Posted December 29, 2001 Report Share Posted December 29, 2001 OH! Was there a previous discussion on this topic? I thought this was the first post. Yeah, that was way off base. " Sinusoidal loading " sounded like characteristics of loading parameters. Neeever mind! :-) By the way, is the 1-6 method any good for strength gain?
