Postactivation Potentiation & Complex Training
An appropriate warm-up prior to physical exertion has been shown to improve subsequent performance however multiple muscular contractions will cause fatigue and reduce subsequent performance capability. If the resultant fatigue can be reduced while still maintaining the "potentiation" caused by prior muscular activity subsequent performance can therefore be increased. This phenomenon has been termed postactivation potentiation.
Complex training involves the execution of a heavy strength exercise followed by a biomechanically similar power movement e.g. bench press followed by medicine ball chest pass. The goal of complex training is to use the principles of PAP to potentiate the muscle for subsequent power-based efforts within the prior heavy strength exercise.
The learning resources below are all on this topic and cover a range of contemporary issues such as what the mechanisms are that lead to PAP, the difference between PAP and PAPE and guidelines related to the exercise prescriptions and timings that have been shown to optimise a PAP effect.
