Are Nordic falls an effective exercise to prevent hamstring injury?



          La resistencia a la fuerza de los músculos ISQUIOSURALES es un factor de riesgo debido a las numerosas lesiones de los mismos en deportistas. Ya vemos diariamente a numerosos futbolistas que sufren lesiones de este tipo por lo que tienen que parar de jugar un largo periodo de tiempo y readaptar la lesión.

 Aquí os muestro un reciente estudio que investigó la efectividad del agarre romano de una sola pierna y las caídas nórdicas para mejorar la fuerza-resistencia del tendón de la corva. 

Doce futbolistas con un historial de lesión de isquiosural fueron aleatorizados en 2 grupos que realizaron 6 semanas de trabajo diferenciado.
Se midió la fuerza-resistencia del puente de glúteo (SLHB) como base para observar las mejoras al termino de las 6 semanas en ambos grupos.




Por un lado, el grupo de silla romana (Single-Leg Roman Chair Hold) mostró una mejora de la magnitud elevada, muy buen rendimiento en SLHB para ambas piernas: (23.7% para la pierna previamente lesionada y 16.9% para la pierna no lesionada).

Por el otro lado, el grupo de caídas nórdicas no mostró apenas cambio  en el rendimiento SLHB: (para la pierna no lesionada -2.1%  y un cambio poco claro, pero posiblemente trivial para la pierna previamente lesionada 0.3%).

Este estudio demostró que el entrenamiento en silla romana de una sola pierna de 6 semanas mejoró sustancialmente el rendimiento de SLHB, lo que sugiere que puede ser una estrategia eficaz para mitigar el riesgo de lesión isquiosural. Por el contrario, el entrenamiento de caídas nórdicas de 6 semanas no mejoró sustancialmente el rendimiento de SLHB, lo que sugiere que esta no debe ser la elección principal para evitar este riesgo de lesión.

The resistance to the strength of the ISQUIOSURAL muscles is a risk factor due to the numerous injuries of the same in athletes. We already see many players on a daily basis who suffer injuries of this type so they have to stop playing a long period of time and readjust the injury.




Here I show you a recent study that investigated the effectiveness of the Roman grip of a single leg and the Nordic falls to improve the strength-resistance of the hamstring.




Twelve players (mean ± standard deviation age, height and mass were 25.17 ± 3.46 years, 179.25 ± 5.88 cm, 85.75 ± 4.75 kg) with a history of hamstring injury were randomized into 2 groups that performed 6 weeks of differentiated work.


The strength-endurance of the gluteal bridge (SLHB) was measured as the basis for observing improvements at the end of 6 weeks in both groups.




On the one hand, the Roman chair group showed an improvement of the high magnitude, very good performance in SLHB for both legs: (23.7% for the leg previously injured and 16.9% for the non-injured leg).



On the other hand, the group of Nordic falls showed little change in SLHB performance: (for the uninjured leg -2.1% and an unclear change, but possibly trivial for the leg previously injured 0.3%).




This study demonstrated that the 6-week single-leg Roman chair training substantially improved the performance of SLHB, suggesting that it may be an effective strategy to mitigate the risk of hamstring injury. In contrast, the 6-week Nordic fall training did not substantially improve SLHB performance, suggesting that this should not be the main choice to avoid this risk of injury.
