Theoretical and Practical Aspects of Strength Power Potentiation Complexes Presented by G. Gregory Haff, Ph.D., C.S.C.S.*D, FNSCA, ASCC @Doc_Haff

PAP: A Tool For Improving Elite  Performance? • To achieve high levels of  strength and power in elite  athletes is there something  we can do? • Strength Power Potentiating  Complexes may offer a mixed  method tool to maximize  performance and engage a  PAP response

PAP: Factors Affecting Performance There are specific factors that impact the ability of SPPC to improve performance

Tillin NA, Bishop D. Sports Med 2009;39:147‐166.

PAP: Fitness Fatigue Paradigm • Since fatigue dissipates at a faster rate than the PAP effect the time course between the condition activity and the performance is of particular importance – The magnitude of work encountered in the conditioning activity will greatly affect this time course • The greater the amount of work the larger the fatigue effects which mask the PAP effects • The greater the work the longer the time delay before potentiation occurs Stone MH, Sands WA, Pierce KC, et al.. Int J Sports Physiol Perf 2008;3:55‐67. Sale DG. Exerc Sport Sci Rev 2002;30:138‐143.

PAP: Fitness Fatigue Paradigm • The volume or workload encountered in the conditioning dictates the time frame needed before potentiation can be realized – Low volume conditioning activity = shorter time delay before potentiation occurs (window 1) – Higher volume conditioning activity = longer time delay before potentiation occurs (window 2)

PAP: What Subject Characteristics  Underpin? • There appears to be  variable responses to  SPPCs so what is the  subject characteristics  that could impact ones  ability to utilize this  training tool?

PAP: Training Experience has an  Impact?

Seitz LB and Haff GG.  Sports Medicine, a head of press.

PAP: Is it Training Experience or  Something Else? • Trained athletes are often – Better trained – Stronger – Have specific physiology to  match their sport

• So is it training experience  or these factors which  impact PAP responses?

PAP: Is it Strength or Something Else? • Stronger people often have  different physiological  attributes – Higher Type II percentages?

• So is it strength or  physiological make‐up which  impact PAP responses?

PAP: Impact of Individual Fiber Type  Distribution • Type II fibers – are associated with muscular strength r=0.5-0.93, p1.5

SPPC: Practical Applications • Based upon acute studies and the physiological mechanisms associated with postactivation potentiation the most logical application of strength-power-potentiating complexes would be in phases of the periodized training plan which target power or speed development
