Resumo
The purpose of this study was to compare the
acute effect of 2 different resting intervals (RI)
between sets of isokinetic knee extension exer-
cise on peak torque (PT) and total work (TW) in
breast cancer survivors (BCS) and control group
(CNT). 16 BCS (52 ± 4 years) and 14 CNT (53 ± 6
years) performed 3 sets of 10 unilateral isoki-
netic knee extension repetitions at 60 °.s − 1 on 2
separate days with 2 different RI between sets (1
and 2 min). There was a significant interaction
between groups vs. exercise sets (p = 0.03) and RI vs. exercise sets (p < 0.001) for PT. PT was greater
in CNT at 1 st and 2 nd sets compared to BCS group
(CNT, 133.4 ± 20.8 and BCS 107.6 ± 19.9 Nm,
p = 0.012 and CNT, 118.9 ± 19.6 and BCS,
97.1 ± 15.9 Nm, p = 0.045, respectively). The TW
of the knee extensor was significant greater in
CNT than BCS group for all 3 knee extension
exercise sets. In conclusion, the present study
suggests that Breast Cancer Survivors women
may need a longer rest interval (longer than
2 min) to be able to fully recover during a 3 sets of
isokinetic knee extension exercise training ses-
sion.
