Abstract:
OBJECTIVES: This study aimed to (1) compare the
effectiveness of a Nordic hamstring exercise (NHE) versus
single-leg Romanian deadlift (SLRDL) exercise programme
on a hamstring injury risk surrogate; (2) compare
the muscle soreness experienced by both exercise
programmes; and (3) assess compliance to remote injury
prevention exercise protocols through video software.
METHODS: Twenty participants (10 women and 10 men:
21.45±1.6 years; 176±23 cm; 70±10 kg) were randomised
into an NHE or SLRDL programme for 6weeks. Single-leg
hamstring bridge (SLHB), a hamstring injury surrogate, was
the primary outcome for exercise efficacy. Muscle soreness
and exercise adherence were also assessed. Significance
was set at p<0.05.
RESULTS: Both exercises increased SLHB performance
resulting in an overall effect (p=0.013) with no effect
for group (p=0.470) and no interaction effect (p=0.709),
indicating both groups improved but there was no
difference in improvement between interventions. There
was no difference in muscle soreness between groups
(p=0.087). Finally, both groups had 100% adherence to the
programme.
CONCLUSIONS: Both the NHE and SLRDL are equally
effective in increasing SLHB performance and demonstrate
a similar level of muscle soreness. This suggests that
SLRDL may be a viable option as a preventative exercise to
mitigate the risk of hamstring injury. Finally, implementing
injury prevention programmes remotely has the potential
to enhance adherence.
