RESUMO
The Nordic Hamstring Exercise (NHE) improves the strength of the
hamstring muscles, as well as prevents and rehabilitates the injuries
of said muscles. However, the eccentric demand of NHE may influence
the athlete’s performance, making compliance with these
programmes difficult. The aim is to analyse the acute impact on
sprint performance after the passing of 24, 48, and 72 hours respectively
since an NHE-based session (4 sets of 10 repetitions) had
taken place. Participants were randomly divided into an experimental
group (EG) (n = 12 male participants) who carried out an NHE
session and a measurement of their 30 m sprint performance in
each of the three subsequent days, and a control group (CG) (n = 12
male participants) who did not take part in the NHE session. The
results show a significant reduction of maximum power within
24 hours (t = 3.57, d = 0.22, P < .0273) as well of the production of
high speed horizontal force up to after 48 hours (t = 4.82, d = 0.22,
P < .0001) in the EG. These results may suggest separating weekly
NHE sessions from competition or demanding training in which
sprint performance should not be affected by at least 72 hours.
