Why the study?
It was unclear whether postactivation potentiation increases voluntary performance.
Does postactivation potentiation (PAP) increase voluntary performance?
Does postactivation potentiation (PAP) increase voluntary performance?
Postactivation potentiation does not guarantee improved voluntary performance, suggesting other mechanisms may be more relevant for acute performance increases following conditioning contractions.
PAP occurrence alone warrants no performance-enhancement changes; leaves open whether extreme levels or other mechanisms drive acute gains.
The occurrence of PAP does not necessarily mean that the voluntary performance will be improved. Improvement in voluntary performance is sometimes observed when the PAP level reaches extremely high values. Other mechanisms may be more relevant than that for PAP in the manifestation of acute increases in performance following a conditioning contraction.
