    Title: Psychological and pedagogical factors that influence player performance in youth football Objectives: The objective of the theoretical part is to analyze the psychological development of the player and the pedagogical aspects influencing the performance from the point of view of the educational activities of the coaches and parents. The selected theoretical starting points are then linked to the player's game play and its sporting development. The content of the research section is to examine the emotional reactions of the players of the preparatory and pupil categories in the clubs AC Sparta Praha and FK Dukla Praha. We analyzed the results of the emotional experience of the players and then we analyzed the differences of factors in the developmental stages of the sporting development and the results of the differences of emotional reactions of the players of both clubs. Methods: In this work we used a questioning method, namely a standardized DEMOR emotional reaction questionnaire examining emotional reactions of pupils. We have adapted it to the sport training environment and piloted. The research was conducted in seven teams of the AC Sparta Prague Football Club and seven teams of FK Dukla Prague in the U9-U15 category. Results: The results showed high values of positive emotional..

    <p>Square-root dense/breast area is the width of a square representing the dense/breast area; square-root PD is the width of a dense-area square within a 10 cm × 10 cm square. All models are adjusted for age, BMI, BMI2, parity, age at first birth, HRT use (never, ever, past, current, not known), MD reader, image type, and mammography view.

    Association of square-root percent mammographic density with menopausal status and age.

    <p>Associations of square-root percent density, by population group, with (a) menopausal status, (b) age among premenopausal women, and (c) age among postmenopausal women, meta-analysed overall and by ASR in source population (low, medium, high). Associations are adjusted for age (for [a] only), BMI, BMI2, parity, age at first birth, HRT use (never, current, former, ever, unknown), mammography view, and MD reader. Full names and details of studies/population groups presented in this figure are provided in <a href="http://www.plosmedicine.org/article/info:doi/10.1371/journal.pmed.1002335#pmed.1002335.s011" target="_blank">S1 Text</a>. Chile is excluded from (a) and (c) as all women were premenopausal. Norway, Australia (Greek), and Australia (Italian) were not included in (a) and (b) as all women were postmenopausal. Turkey was excluded from (a) as selection of women implied that age completely determined menopausal status. ASR, age-standardised incidence rate; BMI, body mass index; CI, confidence interval; HRT, hormone replacement therapy; MD, mammographic density; PD, percent mammographic density.</p
