Comparison of the effect of semi-rigid ankle bracing on performance among injured v. non-injured adolescent female hockey players

Objective. To determine the comparative proprioceptive performance of injured v. non-injured adolescent female hockey players wearing an ankle brace.Methods. Data were collected from 100 high school players who belonged to the Highway Secondary School Hockey League, KwaZulu-Natal, via voluntary parental informed consent and player assent. Players completed an injury questionnaire probing the prevalence and nature of hockey injuries (March - August 2013). Subsequently, players completed a Biodex proprioceptive test with and without an ankle brace. Probability was set at p≤0.05.Results. Twenty-two players sustained ankle injuries within the 6-month study period (p<0.001). Injured players performed similarly without bracing (right anterior posterior index (RAPI) 2.8 (standard deviation (SD) 0.9); right medial lateral index (RMLI) 1.9 (0.7); left anterior posterior index (LAPI) 2.7 (0.9); left medial lateral index (LMLI) 1.7 (0.6)) compared with bracing (RAPI 2.7 (1.4); RMLI 1.8 (0.6); LAPI 2.6 (1.0); LMLI 1.5 (0.6)) (p>0.05). However, bracing improved the ankle stability of the non-injured group (RAPI 2.2 (0.8); RMLI 1.5 (0.5); LAPI 2.4 (0.9); RMLI 1.5 (0.5)) compared with their performance without a brace (RAPI 2.5 (1.0); RMLI 1.8 (0.8); LAPI 2.8 (1.1); LMLI 1.8 (0.6)) (p<0.05).Conclusion. Ankle bracing did not enhance the stability of injured ankles. However, ankle bracing has an ergogenic effect that enhances the stability of healthy ankles.

Introduction: Mounting evidence suggests that mindfulness is positively related to athletic performance and athlete wellbeing. However, few attempts have been made to uncover the psychological processes by which mindfulness might impact performance. Objective: To determine whether negative self-appraisal mediates the relationship between mindfulness and the confidence component of mental toughness among provincial adolescent female hockey players. Methods: Provincial adolescent female hockey players (N=486) completed measures of mindfulness, mental toughness-related confidence and negative self-appraisal. Correlation coefficients were calculated between all variables included in the study. An ordinary least-squares regression analysis was performed to test the indirect effect of negative self-appraisal on the relationship between mindfulness and confidence. Results: Negative self-appraisal exhibited an indirect effect on the relationship between mindfulness and the confidence component of mental toughness (b = .06, SE = .0, CI95 = .04, .09). A subsequent Soble test confirmed that negative self-appraisal served as a statistically significant mediator (b = .06, SE = .01, Z = 5.76, p = .001) in the model. Furthermore 78.3% of the variance in the effect of mindfulness on the confidence component of mental toughness was accounted for by negative self-appraisal. Conclusion: The effect of mindfulness on the confidence component of mental toughness among adolescent athletes is mediated by negative self-appraisal. Based on the current findings, mindfulness seems to foster confidence by lessening the impact of rigid negative appraisals of one’s performance and worth as an athlete.

Introduction: Mental toughness is highly valued within competitive sport. However, scant attention has been paid to the psychological processes that underpin mental toughness.Objectives: To explore the relationship between mindfulness and mental toughness among provincial adolescent female hockey players.Methods: Provincial adolescent female hockey players (N=484) completed measures of mindfulness and mental toughness. Correlation coefficients were calculated with respect to mindfulness and mental toughness. A one-way between-groups analysis of variance (ANOVA) was conducted to determine whether athletes assigned to four levels of mindfulness (high, moderate, medium and low) differed significantly with regard to mental toughness.Results: Mindfulness exhibited significant positive correlations with confidence, constancy and control, as well as with total mental toughness. The results of the ANOVA and the relevant post hoc analyses indicated that athletes in the high mindfulness group reported significantly higher levels of control and general mental toughness than those in the other three groups. The high mindfulness participants also reported significantly higher levels of constancy than those in the medium and low mindfulness groups. Conclusion: Mindfulness was positively correlated with all aspects of mental toughness investigated in this study. In addition, individuals with high levels of mindfulness reported higher control, constancy and general mental toughness than those with lower levels of mindfulness. Based on the current findings, the role of mindfulness in the development and maintenance of mental toughness among adolescent athletes warrants further investigation.

Background The aim of this study was to determine the clinical efficacy of combining self-management strategies and a social thinking approach to address the social performance and executive function of an adolescent female with autism spectrum disorder. Method This research examined the effects of a social knowledge training program, “Think Social,” as well as strategies to improve higher order cognitive abilities. Results and Conclusion Although quantitative improvement was not found, several qualitative gains in behavior were noted for the participants of this study, suggesting a benefit from using structured environmental cues of self-management strategies, as well as improved social understanding through social cognitive training.
