Resumen
[ES]OBJETIVOS: El objetivo principal fue realizar un análisis descriptivo a través de la medición del dolor de espalda, la estabilidad postura! y la resistencia muscular, en un grupo de corredores de fondo (montaña o asfalto). Los objetivos específicos fueron analizar diferencias entre sexos, entre distinta especialidad y entre grupos de edad, además de valorar los factores que pueden influir en el dolor de espalda. MATERIAL Y MÉTODOS. Estudio transversal descriptivo con 55 fondistas. Se realizó la valoración del dolor mediante la Escala Numérica, Escala de Incapacidad por Dolor Lumbar de Oswestry y algometr ía; de la estabilidad postura! mediante estabilometr ía y de la resistencia muscular lumbar mediante el Test Biering-Sorensen . RESULTADOS Y CONCLUSIONES En cuanto a la comparación entre géneros, los hombres tienen un mayor umbral del dolor que las mujeres, al igual que una mejor estabilidad postura!. Sin embargo las mujeres poseen mayor resistencia muscular que los hombres. Con respecto a las diferencias entre especialidades, los corredores de montaña tienen mayor umbral del dolor que los corredores de asfalto. En relación a la edad el umbral del dolor es menor en el grupo más joven que en el resto de grupos. Se concluye también que una menor estabilidad postura! está asociada a un mayor dolor de espalda, que existe relación entre los años de experiencia y una mejor estabilidad postura! y que hay una correlación negativa entre la resistencia muscular y el peso, la estatura y el IMC de los sujetos.
[EN]OBJECTIVES: The main purpose of this study was to perform a descriptive analysis through the measurement of back pain, postura! stability and muscular endurance on a group of long-distance runners (mountain runners or road runners). The specific purposes were to establish if there are differences between men and women, different specialities and age groups, as well as to assess the factors that can have influence on back pain. MATERIAL AND METHODS: A descriptive cross-sectional analysis was conducted on 55 long-distance runners. The Numeric Rating Scale, the Oswestry Low Back Pain Disability Questionnaire and algometry were used to evaluate the pain, stabilometry was used to evaluate the postura! stability and the Biering-Sorensen Test was used to evaluate the low back muscular endurance. RESULTS AND CONCLUSIONS : The gender comparison shows that men have a higher pain threshold than women, as well as better postura! stability. However, women have greater muscular endurance than men. Regarding the differences between specialities, mountain runners have a higher pain threshold than road runners. As far as age is concerned, the pain threshold is lower in the youngest group than in any other age group. lt can also be concluded that a lower postura! stability is related to a greater back pain, that there is a relation between the years of experience and a higher postura! stability and that there is a negative correlation between muscular endurance and the weight, height and BMI of the subjects.
