This study was conducted to analyze whether internal (IR) and external (ER) rotator shoulder muscles weakness and/or imbalance collected through a preseason assessment could be predictors of subsequent shoulder injury during a season in handball players. In preseason, 16 female elite handball players (HPG) and 14 healthy female nonathletes (CG) underwent isokinetic IR and ER strength test with use of a Con-Trex® dynamometer in a seated position with 45° shoulder abduction in scapular plane, at 60, 120 and 240°/s in concentric and at 60°/s in eccentric, for both sides. An imbalanced muscular strength profile was determined using -statistically selected cut-offs from CG values. For HPG, all newly incurred shoulder injuries were reported during the season. There were significant differences between HPG and CG only for dominant eccentric IR strength, ER/IR ratio at 240°/s and for IRecc/ERcon ratio. In HPG, IR and ER strength was higher, and ER/IR ratios lower for dominant than for nondominant side. The relative risk was 2.57 (95%CI: 1.60-3.54; P<0.05) if handball players had an imbalanced muscular strength profile. In youth female handball players IR and ER muscle strength increases on the dominant side without ER/IR imbalances; and higher injury risk was associated with imbalanced muscular strength profile.

These results can potentially identify intrinsic risk factors for shoulder injury and may be used to determine potential interventions for reducing this risk in handball players.

Objective: To assess the prevalence of trauma injuries in triathletes and look for contributing factors involved. Method: An anonymous questionnaire about trauma history during the past season was sent by post to 788 triathletes from a French league. Results: 52.4% of triathletes responding reported having been injured at least once during the past season, for 17% of them several times. 83.5% of injuries occurred during training, mostly in running (72.5%). The tendinopathies (44.5%), and muscle injuries (35%), were the most frequently reported. The anatomical sites most frequently reported were the ankle (20.6%), knee (18.3%), thigh (15%), lumbar region (12.6%) and shoulder (8,3%). 77% of injured triathletes were able to keep training, mainly in swimming (71%) and cycling (61.5%), while running was stopped in 85.5% of cases. Injured triathletes reported devote significantly less time to warmup than uninjured triathletes (respectively 13.7 min vs. 18 min) (p < 0.01). Time devoted to stretching was also lower for injured vs. uninjured (respectively 8.3 min vs. 10.6 min) (p < 0.01). The same association was also found between time spent warming up and stretching and the prevalence of tendinopathies.The prevalence of muscle injuries was significantly associated with number of training hours per week (p < 0.05) and weekly training distance swimming, cycling and running (p < 0.05). Conclusion: Injuries encountered in amateur triathletes are musculoskeletal injuries of «overuse», occurring mainly in training, especially running. © 2011 Consell Català de l'Esport.

PALABRAS CLAVE Prevalencia de lesiones en triatletas de una liga francesaResumen Objetivo: Evaluar la prevalencia de traumatismos en triatletas y buscar los factores contribuyentes implicados. Método: Se envió por correo un cuestionario anónimo sobre los casos de traumatismos durante la temporada pasada a 788 triatletas de una liga francesa. Resultados: El 52,4% de los triatletas que respondieron notificaron que habían sufrido como mín-imo una lesión durante la temporada pasada y el 17% varias lesiones. El 83,5% de las lesiones se produjeron durante el entrenamiento, sobre todo corriendo (72,5%). Los casos notificados con más frecuencia fueron tendinopatías (44,5%) y lesiones musculares (35%). Las zonas anatómicas notificadas con más frecuencia fueron el tobillo (20,6%), la rodilla (18,3%), el muslo (15%), la región lumbar (12,6%) y el hombro (8,3%). El 77% de los triatletas lesionados pudieron seguir entrenando, sobre todo haciendo natación (71%) y ciclismo (61,5%), mientras que en el 85,5% de los casos tuvieron que dejar de correr. Los triatletas que habían sufrido lesiones notificaron que dedican un tiempo signific...
