How to understand sports and traditional games and how to apply it to physical education. On the "Goal of Game".

Introduction: Does philosopher's stone exist in physical education? It could be said that teaching games for understanding approach (TGfU) keeps turning everything it touches into gold: its presence in the educational centers, its volume of publications, the way of teaching games and sports, its connections with other approaches, its game categories, learning transferable principles of play. But… no, all that glitters is not gold. There are TGfU issues that should be improved. For example, these categories are disconnected from each other because TGfU lacks classification criteria. The "goal of game" is a concept that has been studied, but it has not been applied to physical education. The aim of the article is to show how to deepen the understanding sports and traditional games from the "goal of game", and to propose its applicability to physical education. Methods: The traits of "goal of game" will be identified by investigating two close concepts, "prelusory goal" (formalist philosophy of sport) and "motor-goal" (motor praxeology). Results: The traits of "goal of game" concept: main-motor-problem, described in the game rules and that the players will try to solve during the game dynamics. The "goal of game" chances: (1) It allows us to understand sports and traditional games based on their internal logic (2) It allows us to classify traditional games and sports based on classification criteria and that can be useful to organize the physical education program; (3) It allows us to deepen the understanding of sporting games and their applicability to physical education: on the one hand, proposing progressively more specific goal of game options and, on the other hand, proposing a network model of intentions of play to understand the game dynamics and to design learning tasks. Conclusions: The conclusions collect some properties of the "goal of game" concept in order to propose its applicability in physical education students learning: identify and compare the main-motor-problems of the games; solve these problems during the game dynamics; transfer the procedures used to solve other games. The goal(d) of game amazes us; maybe physical education teachers are curious to continue discovering this wonderful treasure.

Efectos del COVID-19 en la carga externa en el fútbol de alto nivel / COVID-19 Effects in External Load in High Level Football

Analizamos el efecto del cese de la competición por COVID-19 en el rendimiento físico de jugadores de fútbol de la 1ª división española). La muestra se estratificó en tres grupos: rondas 1ª-3ª; 25ª-27ª y 28ª-30ª. Las comparaciones por pares fueron Student-t y Mann-Whitney U. Usamos un valor p de ≤0.05 como criterio para la significación estadística. Los valores de umbral para evaluar las magnitudes del tamaño del efecto se realizaron a través (d de Cohen). Tras el parón, las distancias recorridas aumentaron en los equipos locales y visitantes. Hubo un ligero descenso de los esfuerzos de alta intensidad entre el post-confinamiento y las jornadas (25ª-27ª). Comparados el 1er y 3er periodo, los valores fueron ligeramente superiores (rondas 28ª-30ª). Eso mismo se observó en las de aceleraciones y desaceleraciones, con mayores diferencias entre los periodos (1º y 3º). Hubo diferencias, cuando se comparó la reanudación con las jornadas previas al parón. (AU)

We analyzed the effect of the cessation of competition for COVID-19 on the physical performance of soccer players in the 1st Spanish division). The sample was stratified into three groups: 1st-3rd rounds; 25th-27th and 28th-30th. Pairwise comparisons were Student-t and Mann-Whitney U. We used a p-value of ≤0.05 as the criterion for statistical significance. Threshold values​​for evaluating effect size magnitudes were made using (Cohen's d). After the break, the distances traveled increased for the local and visiting teams. There was a slight decrease in high intensity efforts between post-confinement and the days (25th-27th). Comparing the 1st and 3rd period, values ​​were slightly higher (rounds 28-30). The same was observed in those of accelerations and decelerations, with greater differences between the periods (1st and 3rd). There were differences when the resumption was compared with the days before the break. (AU)

Frontal Fibrosing Alopecia: A Retrospective Study of 75 Patients. / Alopecia frontal fibrosante: estudio retrospectivo de 75 pacientes.

BACKGROUND AND OBJECTIVE: Frontal fibrosing alopecia is an increasingly common form of scarring alopecia. The aim of this study was to describe the demographic and clinical characteristics of patients with FFA seen at the trichology unit of a medium-sized regional hospital and to report on treatments used. MATERIAL AND METHOD: We reviewed the medical records of all patients with FFA seen at the trichology unit of Hospital Universitario Infanta Sofía in Madrid, Spain between May 2016 and May 2018. We analyzed associations between disease severity, clinical patterns, need for oral medications, and other characteristics. RESULTS: Seventy-five patients (73 women and 2 men) were studied. Diagnosis was clinical in most cases and 13 cases (17.3%) were confirmed histologically. Median (interquartile range) age at reported onset of symptoms was 61 (12) years. Involvement of the eyebrows was recorded in 70 patients (93.3%) and signs of oral and genital lichen planus in 7 (9.6%). Eleven patients (14.7%) had hypothyroidism and 15 (20.0%) had signs of rosacea. Only 5 of the patients who presented a linear pattern (21.7%) had severe hairline recession. Patients with unstable and/or symptomatic disease (n=24) were treated with oral medications (5-alpha reductase inhibitors, hydroxychloroquine, corticosteroids, and isotretinoin) or intralesional corticosteroids. Eighteen patients (75.0%) achieved disease stability. Ten of the 15 patients with signs of rosacea and 10 of those with facial papules required systemic treatment. CONCLUSION: Most of the patients in this series of FFA were postmenopausal women. The prevalence of oral and genital lichen planus was higher than that observed in the general population. Patients with a linear pattern had less severe disease. Facial papules were more common in younger patients and both facial papules and rosacea were associated with a greater need for oral treatment.

Body dysmorphic disorder in patients with acne: a multicentre study.

BACKGROUND AND OBJECTIVE: Body dysmorphic disorder (BDD) is a mental disorder that is difficult to diagnose, causes a lot of suffering and is more prevalent in dermatology patients than in the general population. Our objective was to screen for possible cases of BDD in patients with acne and to determine the prevalence according to DSM-IV and DSM-5 criteria, as well as to analyse the relationship between dermatological and sociodemographic variables. METHODS: A total of 245 patients diagnosed with acne in 11 dermatological centres in Spain were included in the study by members of the Aragon Psychodermatology Research Group and Spanish Research Group of Psychiatric Dermatology. We used the Body Dysmorphic Disorder Questionnaire (BDDQ) as a screening tool. RESULTS: In our sample, we obtained a prevalence for BDD of 10.6% (95% CI: 7.6-13.6%). The prevalence was the same with DSM-IV or DSM-5 criteria. Possible cases of BDD were predominantly women (P = 0.021), and 56% had non-inflammatory lesions vs. 30% of negative patients (P = 0.002). Positive patients as possible cases of BDD spent more than two hours on average a day worrying about their appearance. Most people only worried about one part of their body (86%), and in 95% of the cases, the part of their body that worried them was the face. The three most frequent compulsive behaviours in patients who screened positive for BDD were mirror checking (90.7%), camouflaging (79.1%) and using make-up (72.1%). CONCLUSIONS: As a consequence of the high prevalence of possible cases of BDD in patients with acne observed in our study, there is a need for dermatologists to screen for BDD so that they can be referred to a mental health unit to confirm the diagnosis and be offered treatment to reduce the progression of psychosocial deterioration and the development of comorbid disorders.
