Limited ranges of motion (ROM) have been considered as a relevant risk factor for team sports injuries. The main purposes of the current study were to describe the lower extremity ROM profile, muscular tightness and asymmetries in elite inline hockey players and to examine sex-related differences. Twenty professional inline hockey players from 2 Spanish National Teams (male and female) were measured of passive hip extension [HE], hip adduction with hip flexed 90° [HAD-HF], hip flexion with the knee flexed [HF-KF] and extended [HF-KE], hip abduction with the hip neutral [HAB] and hip flexed 90° [HAB-HF], hip external [HER] and internal [HIR] rotation, knee flexion [KF], ankle dorsiflexion with the knee flexed [ADF-KF] and extended [ADF-KE] ROMs of the dominant and non-dominant leg ROMs were taken. A paired t-test was carried out to assess asymmetries. ROM values were classified as “normal versus tightness”, and “normal versus asymmetry” according to the proposed reference values. The effect size for each variable was analyzed. Male team exhibited asymmetry in HF-KF (133.2° dominant vs. 129.8° non-dominant; p = 0.042; d = 0.7243 [moderate effect sizes]) and female team in ADF-KF (38.8° dominant vs. 41.0 non-dominant; p = 0.001; d = 0.6 [moderate effect sizes]) and HAB ROM (41.2° dominant vs. 38.8 non-dominant; p = 0.005; d = 1.1767 [moderate effect sizes]). Male players reported asymmetry in HAD-HF (n = 5), HER (n = 4) and HE (n = 3), whereas female players presented asymmetries in HER (n = 4), HE (n = 3) and KF (n = 2). Overall, 20–100% of all participants showed limited KF, HF_KE, HIR, HE, ADF_KF, HAD-HF, HF-KF, ADF_KE, HTR and HER ROM. The results of this study reinforce the requirement of prescribing exercises aimed at improving hip, knee and ankle ROM within everyday inline hockey practices. In addition, as some asymmetries were found, unilateral flexibility training should be considered where appropriate.

Flexibility in Spanish Elite Inline Hockey Players: Profile, Sex, Tightness and Asymmetry

“…The differences between our study and those reported previously may be explained by the sport-specific movements performed by athletes. In this sense, a large number of studies have confirmed that flexibility is specific to each sport [ 85 , 86 ] and tactical position [ 87 , 88 ] and may also depend on the competitive level of the players [ 89 , 90 ]. Skating is a unique pattern of movement in sport and the most important basic skill in IH.…”

External and Total Hip Rotation Ranges of Motion Predispose to Low Back Pain in Elite Spanish Inline Hockey Players

Low back pain (LBP) is a common ailment in competitive athletes. Although the association between limited range of motion (ROM) and prevalence of LBP has been widely investigated in other sports, there is no research about this topic in inline hockey (IH). The main purposes of this study in IH players were (1) to analyze the association between hip ROM and LBP and (2) to establish a diagnostic cutoff for ROM of high risk of LBP. Twenty elite IH players from the two Spanish National Teams (male and female) were assessed for passive maximum hip ROMs; the movement evaluated were the hip external [HER] and internal [HIR] rotation, hip flexion with flexed [HF-KF] and extended [HF-KE] knee, hip adduction with flexed hip [HAD-HF], hip abduction with neutral [HAB] and flexed [HAB-HF] hip, and hip extension [HE]. LBP was retrospectively monitored for the last 12 months before the date of ROM assessment by using a questionnaire. The data were analyzed via a binary logistic regression and receiver operating characteristic curves. The 70% of players had developed LBP during the retrospective study period. Significant differences between LBP group and asymptomatic group for HER (p = 0.013, d [Cohen’s effect size] = 1.17) and hip total rotation [HTR] (p = 0.032, d [Cohen’s effect size] = 1.05) were observed. The cutoff points with the greatest discriminatory capacity were 56.5° for HER and 93° for HTR ROMs.

“…Ante estos hechos, los entrenadores personales, preparadores y readaptadores físicos precisan de valores de referencia del perfil de flexibilidad que determinen los objetivos cuantitativos de entrenamiento de la flexibilidad atendiendo a la especificidad de esta habilidad motora básica como el tipo de deporte (Hogg et al, 2018;Moreno et al, 2004), sexo De la Fuente & Gómez-Landero, 2019;Hogg et al, 2018) y etapa federativa (Cejudo, Robles-Palazón, Ayala, et al, 2019) según el modelo de desarrollo deportivo a largo plazo citado previamente. El perfil de flexibilidad óptimo ha sido determinado previamente con valores iguales o superiores al percentil 80 en cada movimiento de una muestra de jugadores en deportistas (Cejudo et al, 2017;Sainz de Baranda et al, 2015a).…”

Desde una perspectiva fundamental, se recomienda desarrollar la flexibilidad en su periodo sensible en el deporte base de acuerdo al modelo de desarrollo deportivo a largo plazo. Sin embargo, estudios previos no han analizado e interpretado el perfil de flexibilidad de jugadores de fútbol en su periodo sensible. El objetivo de este estudio fue determinar el perfil de flexibilidad óptimo en jugadores de fútbol sub-10. Un total de 22 jugadores de fútbol con edades comprendidas entre los 7 y 10 años (edad: 8,9±0,9 años; peso: 33,5±6,3 kg; talla: 136,4±6,7 cm; 14,3±22,8 kg/m2) participaron voluntariamente en este estudio. El perfil de flexibilidad del miembro inferior fue determinado del batería ROM-SPORT a través de sus 11 tests angulares pasivos máximos. Para el establecimiento del perfil óptimo de flexibilidad fue calculado el percentil 80. Los resultados establecen el perfil de óptimo flexibilidad de 22 jugadores de fútbol sub-10 en 21,8º para psoasilíaco, 43,4º para piramidal, 35,0º para gemelo, 39.8º para sóleo, 37,4 para aductores, 62,4º para músculos rotadores externos de cadera, 67,2º para músculos rotadores internos de cadera, 69,0º para aductores monoarticulares, 80º para isquiosural, 145,8º para cuádriceps y 147,0º para glúteo mayor. El presente estudio aporta los primeros valores de referencia del perfil óptimo de flexibilidad de la extremidad inferior en jugadores de fútbol sub-10. Estos valores pueden ser utilizados como objetivos específicos cuantificables en el entrenamiento de la flexibilidad en el periodo sensible de esta cualidad física.
