The present study investigated the effects of different conditioning contractions (CC)
on lower body acute potentiation of counter movement jump (CMJ) performance.
Acutely enhancing muscle performance through the use PAP would allow complex
training to be implemented within programmes designed by strength and
conditioning coaches. A total of 8 male university rugby union players (Height
178.6±9.6cm; Weight 89.6±12.6kg; 1RM 170kg±40kg) took part in 3 separate trials
in which they performed either a 90%, 30% or plyometric (PLYO) CC in a repeated
measures design with a baseline performance measure and post-CC performance
measure present with a total of 10mins rest utilised between baseline performance
measure and CC and a 7min rest period utilised between CC and post-CC
performance measure. The performance measure consisted of 3 CMJ with 1 minute
rest between each measure. There was no significant difference in Ppeak (Peak force)
among the PLYO, 30% and 90% trials (p= 1.000, p=1.000, p=1.000 respectively),
again no significant difference in dmax (maximal displacement) among the PLYO,
30% and 90% trials (p=1.000, p=0.097 and p=1.000 respectively). Likewise there
was again no significant difference in RFD (rate of force development) across the
PLYO, 30% or 90% trials (p=1.000, p=1.000, p=1.000 respectively) and again finally
there was no significant differences in RelF (relative force) in the PLYO, 30% or 90%
trials (p=1.000, p=0.326, p=1.000 respectively). These findings suggest that neither
the PLYO, 30% or 90% has no effect on lower body acute potentiation of counter
movement jump in trained male university rugby players.
