METHODS
Nine p o essional male olleyball playe s ook pa in his
s udy. The neu omuscula pe o mance was es ima ed by
unloaded (CMJ) and loaded coun e mo emen jumps
(CMJloaded) heigh (cm); and by eloci y o displacemen in he
concen ic phase o ull squa (FS) (m•s-1). T aining ook place
2 d•wk-1 du ing 8 weeks (16 sessions) ( able 1). The esis ance
exe cises we e FS, hang powe clean and loaded jump. In FS,
2-3 se ies o 4-6 epe i ions we e ealized wi h a load which
was g adually inc eased om 50% o 65% o 1RM. In powe
clean, 3 se ies o 4-6 epe i ions we e ealized wi h he
maximum load ha allows a co ec echnical execu ion. In
loaded jump, 2-3 se ies o 4-5 epe i ions we e ealized wi h a
load which was g adually inc eased om 50% o 80%
acco ding o he weigh wi h which he a hle es eached a
heigh o abou 20 cm.
RESULTS
The e was a signi ican inc ease in CMJ and CMJloaded (3.4%
and 5.8%; p<0.05; espec i ely). No signi ican changes we e
obse ed in FS (0.14%; p>0.05).
PRACTICAL APPLICATIONS o CONCLUSION
