Pre-season screening is well established within the sporting arena, and aims to enhance performance and reduce injury risk. With the increasing need to identify potential injury with greater accuracy, a new risk assessment process has been produced; The Performance Matrix (battery of movement control tests). As with any new method of objective testing, it is fundamental to establish whether the same results can be reproduced between examiners and by the same examiner on consecutive occasions. ⋯ It is concluded that both inter and intra-rater reliability of tests in The Foundation Matrix are acceptable when rated by experienced therapists. Recommendations are made for modifying some of the criteria to improve reliability where excellence was not reached. Key pointsThe movement control tests of The Foundation Matrix had acceptable reliability between raters and within raters on different daysAgreement between observations made on tests performed real-time and on video recordings was low, indicating poor validity of use of video recordingsSome movement evaluation criteria related to specific tests that did not achieve excellent agreement could be modified to improve reliability.

Compression garments on the lower limbs are increasingly popular among athletes who wish to improve performance, reduce exercise-induced discomfort, and reduce the risk of injury. However, the beneficial effects of compression garments have not been clearly established. We performed a review of the literature for prospective, randomized, controlled studies, using quantified lower limb compression in order to (1) describe the beneficial effects that have been identified with compression garments, and in which conditions; and (2) investigate whether there is a relation between the pressure applied and the reported effects. ⋯ The pressure applied at the level of the lower limb by compression garments destined for use by athletes varies widely between products. There are conflict results regarding the effects of wearing compression garments during exercise. There is a trend towards a beneficial effect of compression garments worn during recovery.

The aim of this study was to investigate the factor structure of a Spanish version of the Sport Motivation Scale adapted to physical education. A second aim was to test which one of three hypothesized models (three, five and seven-factor) provided best model fit. 758 Spanish high school students completed the Sport Motivation Scale adapted for Physical Education and also completed the Learning and Performance Orientation in Physical Education Classes Questionnaire. We examined the factor structure of each model using confirmatory factor analysis and also assessed internal consistency and convergent validity. ⋯ Key PointsPhysical education research conducted in Spain has used the version of SMS designed to assess motivation in sport, but validity reliability and validity results in physical education have not been reported. Results of the present study lend support to the factorial validity and internal reliability of three alternative factor structures (3, 5, and 7 factors) of SMS adapted to Physical Education in Spanish. Although all three models in Spanish produce good indicators of fitness, but we suggest using the seven-factor model.

This study examined links between parents' exercise habits and adolescents' participation in sports activities, considering the aspects of gender and age. It was hypothesized that regular exercise by both parents would be related to children's involvement in sport regardless of their gender and age. Moreover, it was hypothesized that children's sports activities would be more strongly related to their father's exercise activities. ⋯ Regular exercising of both mother and father predicts 13 - 14-year-old adolescents' engagement in sport. However, mother exercising is not related to older adolescents' involvement in sport. Research revealed the relation of adolescents' sport motives and father's exercising, and no differences were established depending on mother's exercise habits.

The aim of the present study was to cross-culturally adapt and validate the Spanish version of the Performance Enhancement Attitude Scale (PEAS). A cross-sectional multi-sample survey with 17 independent datasets was carried out. Cross-cultural adaptation of the PEAS into Spanish was conducted through forward/backward translations, consensus panels and comparative analyses of known-groups to establish evidence for its reliability and validity. ⋯ Users scored higher than non-users indicating a satisfactory construct validity. Significant positive correlation was found between PEAS and projected use. Significant negative correlation between PEAS and self-esteem and self-efficacy.
