Resumo
[Abstract] : The purpose of this study was to compare acute
mechanical and metabolic eff ects of 2 sessions of
resistance training equated by volume and total
resting time but with diff erent set confi guration:
sets to failure (FS) vs. distribution of rest
between each repetition (NFS). 10 male judoists
completed a session consisting of 3 sets to failure
of parallel back squat with 4 repetitions at
maximum load, and a rest of 3 min between the
sets. At least 72 h later subjects developed the
same volume, but total resting time was distributed
among individual repetitions. Before
and after sessions isometric force and mean
propulsive velocity with load corresponding
to maximum propulsive power were assessed.
Results showed that in respect to FS, NFS showed
an 18.94 % ( ± 17.98) higher average mean propulsive
velocity during session (0.42 ± 0.04 vs.
0.35 ± 0.08 m.s − 1 ; p = 0.009), lower blood lactate
concentration after session (maximum average
value 1.52 ± 0.77 vs. 3.95 ± 1.82; session effect:
p = 0.001) and higher mean propulsive velocity
with load corresponding to maximum propulsive
power (mean propulsive velocity immediately
after session 0.64 ± 0.09 vs. 0.59 ± 0.12 m.s − 1 ; session
eff ect: p = 0.019). These data show that distribution
of rest in sessions equated for volume
and total resting time determines differences in
performance during sessions and mechanical or
metabolic acute effects.
