Context:The physical and mental demands of an elite football player are complex, which may explain why injuries are commonin football. At elite level, muscle injuries of the lower-extremity are the most common among male football players, and theresearch hitherto is limited. Objective: To investigate whether personality traits affect the incidence of muscle injuries amongmale football players from the first league in Sweden. Design: Prospective cohort study. Participants: A male football team fromthe first league in Sweden was prospectively followed, in terms of muscle injuries of the lower-extremity during 8 seasons,between 2007 and 2015. Intervention: All muscle injuries included in this study were evaluated and diagnosed withultrasonography. Players from the team filled out the Swedish Universities Scales of Personality questionnaire. SwedishUniversities Scales of Personality questionnaire consists of 91 items and is divided into 13 categories. Main Outcome Measures:The raw values of each scale were linearly transformed to T scores, having a mean (SD) of 50 (10). All variables weresummarized with standard descriptive statistics, such as frequency, mean, and SD. As data were of interval scale and no variabledistribution was severely skewed, differences between noninjured players, rarely injured players, and frequently injured playerswere analyzed with 1-way analysis of variance with post hoc tests by Tukey honestly significant difference test. Results:No significant difference in personality traits were observed between noninjured players, rarely injured players, and frequentlyinjured players regarding number of muscle injuries (P > .05). However, a trend (P = .07) was seen, where frequently injuredplayers scored higher on stress susceptibility than rarely injured players. Conclusion: A player’s stress susceptibility should betaken into consideration by the player, coaches, and medical staff when assessing the risk of a muscle injury. Also, preventivemeasures available for these players may need to be considered.

The extent and depth of traumatic brain injury (TBI) remains a major determining factor together with the type of structural insult and its location, whether mild, moderate or severe, as well as the distribution and magnitude of inflammation and loss of cerebrovascular integrity, and the eventual efficacy of intervention. The influence of exercise intervention in TBI is multiple, ranging from anti-apoptotic effects to the augmentation of neuroplasticity. Physical exercise diminishes cerebral inflammation by elevating factors and agents involved in immunomodulatory function, and buttresses glial cell, cerebrovascular, and blood-brain barrier intactness. It provides unique non-pharmacologic intervention that incorporate different physical activity regimes, whether dynamic or static, endurance or resistance. Physical training regimes ought necessarily to be adapted to the specific demands of diagnosis, type and degree of injury and prognosis for individuals who have suffered TBI. © 2012 John Wiley & Sons A/S.

Muskelskador är vanliga i fotboll. Samtidigt är det kliniskt svårt attavgöra hur allvarliga de är och vilken tid som behövs för rehabilitering.Vi hoppas att vår pågående studie kan fastställa hur lång tid spelarnabehöver innan återgång till träning och match.

This study describes the levels and inter-correlations of physical self-esteem, physical activity, body mass index (BMI), and body fat and, in addition, distinctive of individuals with high vs. low physical self-worth in a longitudinal design during adolescence.

METHODS:

At mean ages 12.7, 15.7, and 17.7 years, physical activity (steps/day) was measured for four consecutive schooldays of 77 (41 girls) Swedish adolescents. Perceived physical self-esteem, height, weight, and at ages 15.7 and 17.7 years, body fat percent was also measured.

RESULTS:

Boys' physical self-perception scores were higher than girls' and an overall stability during adolescents was seen. High and low physical self-worth had a significant impact regarding BMI at ages 12.7 and 17.7 years and regarding body fat at age 17.7 years in both boys and girls.

CONCLUSIONS:

Regression analysis indicated that BMI and body fat counter-predicted self-worth in girls age-dependently. Efforts to build adapted physical activity programs for overweight and obese are emphasized.
