Résumé
Background: Movement velocity has been proposed as an effective tool to prescribe
the load during resistance training in young healthy adults. This study aimed to
elucidate whether movement velocity could also be used to estimate the relative load
(i.e., % of the one-repetition maximum (1RM)) in older women.
Methods: A total of 22 older women (age = 68.2 ± 3.6 years, bench press 1RM = 22.3 ±
4.7 kg, leg press 1RM = 114.6 ± 15.9 kg) performed an incremental loading test during
the free-weight bench press and the leg press exercises on two separate sessions.
The mean velocity (MV) was collected with a linear position transducer.
Results: A strong linear relationship between MV and the relative load was
observed for the bench press (%1RM = -130.4 MV + 119.3; r2 = 0.827, standard
error of the estimate (SEE) = 6.10%1RM, p < 0.001) and leg press exercises
(%1RM = -158.3 MV + 131.4; r2 = 0.913, SEE = 5.63%1RM, p < 0.001). No
significant differences were observed between the bench press and leg press exercises
for the MV attained against light-medium relative loads (>70%1RM), while the MV
associated with heavy loads (>80%1RM) was significantly higher for the leg press.
Conclusions: These results suggest that the monitoring of MV could be useful to
prescribe the loads during resistance training in older women. However, it should be
noted that the MV associated with a given %1RM is significantly lower in older
women compared to young healthy individuals.
