6. Conclusion and practical applications
In conclusion the present data suggest that training using the Romanian deadlift appears to enhance 1RM performance
of the Romanian deadlift but does not specifically strengthen the lumbar extensors.
Therefore, coaches and athletes should ideally employ isolated lumbar extension exercise in addition to the Romanian deadlift if strength increases in the lumbar muscles are also desired.
Given the well documented potential of this area for injury, and the debilitating
effects of injury to the lumbar region, we argue that protection of this vulnerable area should certainly be a priority
for athletes engaged in sports as well as the lay person wishing to remain injury free.
As previous research has shown that isolated lumbar extension exercise can be effective in both prevention
and treatment of lower back injuries (see, for example, Bruce-Low et al.
, 2012; Choi et al., 2005; Leggett et al., 1999; Mooney, Kron, Rummerfield & Holmes; 1995),
we suggest that this exercise would be a valuable addition to many athletes’ strength training regimens,
even when performed in low volume and low-frequency (e.g. 1/week).
In application, although the Romanian deadlift can be a valuable exercise,
strength coaches should not assume that this will be sufficient exercise
for the lumbar extensors as well as for the posterior chain.
