POST-ACTIVATION POTENTIATION OF HORIZONTAL JUMPING – 2016


Seitz, Laurent B.; Mina, Minas A.; Haff, G. Gregory
METHOD
– 14 rugby league players performed a contrast PAP protocol comprising 4 sets of 2 paused box squats accommodated with bands alternated with 2 standing broad jumps
– The rest period between the squats and the jumps and between the sets was 90 seconds
– A control protocol with standing broad jumps only was performed on a separate session
– A standing broad jump was performed ∼2 minutes before each protocol and served as a baseline measurement
RESULTS
1. Standing broad jump distance was significantly greater (4.0 ± 3.4% to 5.7 ± 4.7%) than baseline during the 4 sets of the contrast PAP protocol with the changes being medium in the first, second, and fourth sets and large for the third set
2. Conversely, no PAP effect was observed in the control protocol.
3. The stronger players displayed a larger PAP effect during each of the 4 sets of the contrast PAP protocol and a larger mean effect across these 4 sets
CONCLUSIONS
1. Horizontal jump performance is potentiated after only 90 secs of rest after an accommodating exercise, and this PAP effect can be elicited across 4 sets
2. PAP response is largely mediated by the individual’s strength level
