Provincia de Talca, Chile
Antecedentes y objetivo El pádel ha presentado un desarrollo considerable. Requiere de gestos motores (GM) repetitivos e intensos, los cuales se asocian con lesiones musculoesqueléticas (LME). El objetivo fue evaluar las posturas de hombro y codo durante el GM del saque en bandeja de pedelistas aficionados chilenos.
Metodología Para este estudio observacional y transversal, se reclutaron 30 padelistas de Talca, Chile. Se agruparon en aquellos con historial de LME (cLME, n = 14, edad [IC95%] = 32,9 [29,5-36,4] años) y sin historial de LME (sLME, n = 16, edad [IC95%] = 29,3 [26,7-31,8] años). Se analizaron posiciones angulares en plano sagital de hombro y codo para el GM de saque en bandeja durante el desarrollo de un juego habitual de un campeonato oficial. Se realizó fotogrametría (Kinovea®) para las posturas inicial (comienzo del gesto), media (máxima extensión para preparar el golpe) y final (golpe de la pelota).
Resultados En hombro, la posición inicial es similar en ambos grupos (∼21° de extensión). La posición media es significativamente de mayor extensión en los deportistas sLME (∼55 vs. ∼45°; p = 0,002), manteniéndose en la fase final (∼38 vs. ∼32° de flexión). En codo, las posturas son similares (∼120°). Los deportistas sLME alcanzan mayor extensión relativa al momento del golpe de la pelota (∼141 vs. ∼130°).
Conclusiones El inicio del GM del saque en bandeja tiene posturas angulares similares entre todos los padelistas, sin embargo, los deportistas sLME presentan una postura de mayor extensión de hombro y codo durante las fases media y final.
Background and objective Padel has experienced significant growth. It requires repetitive and intense motor gestures (MG), which are associated with musculoskeletal injuries (MSI). The objective was to evaluate shoulder and elbow postures during the tray serve MG in amateur padel players from Talca, Chile.
Methodology For this observational and cross-sectional study, 30 padel players from Talca, Chile were recruited. They were grouped into those with a history of MSI (wMSI, n = 14, age [95% CI] = 32.9 [29.5-36.4] years) and without a history of MSI (woMSI, n = 16, age [95% CI] = 29.3 [26.7-31.8] years). Angular positions in a sagittal plane of the shoulder and elbow were analyzed for the MG of the serve during a regular game in an official championship. Photogrammetry (Kinovea®) was used for the initial (beginning of the gesture), mid (maximum extension to prepare the stroke), and final (ball impact) postures.
Results For the shoulder, the initial position is similar in both groups (∼21° flexion), while the mid position is significantly more extended in the woMSI athletes (∼55 vs. ∼45°; P=.002), and this remains in the final phase (∼38 vs. ∼32°). For the elbow, the postures are similar (∼120°). The woMSI athletes achieve greater relative extension at the moment of ball impact (∼141 vs. ∼130°).
Conclusions The beginning of the MG of the serve shows similar angular postures among all padel players. However, the woMSI athletes exhibit a posture with greater shoulder and elbow extension during the mid and final phases.
