    Effects of COVID-19 Lockdown on Body Composition and Physical Performance of Elite Female Football Players
    (Human Kinetics, 2022) Rodrigo Villaseca-Vicuña; Jorge Pérez-Contreras; Pablo Merino-Muñoz; Esteban Aedo-Muñoz; González-Jurado, J. A.; Santiago Zabaloy
    The COVID-19 pandemic led to an unusual situation in sports. Players were forced to stay at home for an undefined period of time and not allowed to use any training facilities or even exercise outdoors. Therefore, this study aimed to examine the effects of the COVID-19 lockdown on physical performance and body composition in elite female football players. During the confinement period, 19 players (n = 19, M= 27 years; SD = 4.19) volunteered to participate in the present study. Participants were confined during 5 months and performed six remotely guided sessions a week, designed and structured by a certified fitness coach. Pre- and postconfinement period, players were tested for body composition, strength in the squat exercise, vertical jump, 30-m sprint, kicking velocity, and intermittent endurance capacity (Yo-Yo Intermittent Recovery Level 1). Fat mass and muscle mass remained unaffected after the confinement period, while only body mass showed a significant increase between periods (1.19%; p = .014). In addition, physical performance measures postconfinement showed positive changes in kicking (p < .001; effect size = 1.02), in contrast to a reduction in mean propulsive velocity against 40-kg load and Yo-Yo Intermittent Recovery Level 1 total distance covered (p: .041 and .010, respectively). Present findings indicate that the implementation of home-based training programs during confinement periods could be sufficient stimulus to maintain body composition and physical performance (i.e., strength, vertical jump, and sprint), although they might not be sufficient to maintain intermittent endurance capacity in elite female football players.

    Analysis of the goal‑scoring opportunities conceded in football: a study case in the Spanish La Liga
    (Springer, 2020-11-08) Otero-Saborido, Fernando Manuel; González-Jurado, J. A.; Callejas Jerónimo, Juan Evaristo; Aguado Méndez, Rubén D.
    The study’s aim was to analyse the goal-scoring opportunities conceded by a professional football team. Using observational methodology, all the opportunities conceded (N = 243) by Real Betis in the Spanish La Liga 2017/2018 were analysed through a validated instrument which measured contextual, defensive and attacking variables. Descriptive, inferential, correlational and binary logistic regression statistics were used to determine the predictive models. The results show a relation between the goal-scoring opportunities conceded and the provisional match result, as well as all the defensive and attacking variables analysed. There was a significant relation between the own half loss of the ball (66.3%) and the opportunities conceded. After applying the binary logistic regression, there were significant tactical patterns when the own half loss coincided with other variables: loss between 0′ and 15′ (OR = 4.255) and 46′-60′ (OR = 4.227); 0 or 1 opponent’s pass (OR = 2.829); length of attack less than 3′’ (OR = 5.475) and 1 player of the opposing team got into contact with the ball (OR = 7.358). Other factors such as losing the ball through stealing (OR = 3.127) or the provisional result of a draw (OR = 0.4) predict the possibility of conceding a goal-scoring opportunity in the case studied.

    Analysis of reaction time and lateral displacements in national level table tennis players: are they predictive of sport performance?
    (Routledge, 2019-05-31) Casterllar, Carlos; Pradas, Franciso; Carrasco, Luis; De la Torre, Ana; González-Jurado, J. A.
    Table tennis is a sport in which players perform technical actions at high speed. In this regard, response time (TTR), reaction time (RT) and movement time (MT) are key factors that can contribute to successful performance of table tennis players. The purposes of this study were to determine the magnitude of intra-subject and intersubject variability in TTR based on player’s lateral dominance, to establish possible differences between sex, age group and ranking position for TTR, RT and MT, and to relate these results with table tennis performance by analysing the achieved position in the national ranking. A total of 116 Spanish national level players (71 males and 45 females) carried out the Take-Off Reaction Test in a table tennis court simulating real sport conditions. There were no intra-sex differences for the total sample when lateral dominance was checked. On the other hand, male players showed lower MT than females whereas female players showed significantly lower RT values than males. Moreover, and taken into account the correlation analysis, we can conclude that both lower RT and MT can be considered as key variables of performance in table tennis.

    Analysis of the assessment in Physical Education curricula in Primary Education
    (Routledge, 2020-08-11) Otero-Saborido, Fernando Manuel; Vázquez Ramos, Francisco Javier; Cenizo Benjumea, José Manuel; González-Jurado, J. A.
    One way to understand the Physical Education (PE) curriculum is through assessment. After the appearance in Spain of the learning standard (LS) as a reference for more specific assessment, the main objective of this work was to analyse the assessment aspects for PE in Primary Education in the curricula of Spain’s 17 Autonomous Communities. Documentary analysis of the official regulations was used as a data collection technique. Qualitative and quantitative variables were analysed for the 3,357 assessment references. Qualitative variables included: LS typology and sequencing, and the existence of assessment orientations. Quantitative variables included: the curricular size, the presence of the cognitive, motor, and socio-affective dimensions in the different standards, percentages of comprehensiveness (assessment references which include the three dimensions) and curricular effectiveness (capacity of each curriculum to optimise the standards to include the greatest number of dimensions). The LS was the assessment element generally used by the majority of curricula. The cognitive dimension (39.42%) predominated in the assessment references, at the expense of the motor (30.94%) and socioaffective dimensions (29.65%). Only 11.70% of the 3,357 assessment references used incorporated the three dimensions (cognitive, motor and socio-affective). An inversely proportional relation seemed to exist between curricular size (number of standards) and its comprehensiveness (r = −0.505) and effectiveness (AEC) (r = −0.646). Likewise, it is noted that more LS including the motor dimension is associated with a greater comprehensiveness (2D: r = 0.573) of the curricula (r = 0.721). Lastly, the association between the ‘motor’ and ‘cognitive’ dimension variables was reversed. The curricula analysis showed a very high level of standardisation of PE assessment, which was oriented towards the measuring of theoretical know-how, foregoing comprehensiveness. This trend underlines the curricula’s adopted neoliberal nature and their distancing from assessment models based on student participation and development. A more flexible, democratically constructed curriculum as well as assessment benchmarks are necessary in PE, where motor development and assessment become a means for holistic education.

    Anthropometric Profile and Physical Fitness Performance Comparison by Game Position in the Chile Women’s Senior National Football Team
    (MDPI, 2021-02-24) Rodrigo Villaseca-Vicuña; Edgardo Molina-Sotomayor; Santiago Zabaloy; González-Jurado, J. A.
    The aim of this study was to explore the anthropometric profile and evaluate physical fitness variables of the members of the Chile women’s national football team based on their playing positions. Fifty football players participated in this study, which was carried out during the period of training for the France 2019 Women’s World Cup and the Japan 2020 Olympic Games. Body composition and physical condition (muscular strength, sprint, agility, and aerobic fitness) were assessed. The goalkeepers showed greater weight (p < 0.001), height (p = 0.002), and %Fat (p = 0.010) compared to the rest of the playing positions. There were also differences between positions in relative strength (RS) (p = 0.001), running speed at 10 and 30 m (T10 and T30, respectively), agility (AGI) (p < 0.001), and yo-yo test (MYYR1) (p < 0.001). RS, T10, T30, and countermovement jump (CMJ) were significantly correlated (p ≤ 0.05) with anthropometric variables (p ≤ 0.05). MYYR1 was also significantly correlated with anthropometric variables (p ≤ 0.05). In conclusion, goalkeepers show greater weight and height, as well as worse results in MYYR1, AGI, T10, T30, and RS compared to the rest of the players. Forwards present better performance in running speed and agility. Better performance in physical condition is associated with better body composition values (greater muscle mass and lower fat mass). Greater relative strength indicates greater performance in explosive actions. Therefore, to meet the demands of high competition, it is important to establish ideal profiles in anthropometry and physical condition variables based on the playing position.

    Análisis de la evaluación en los currículos de educación física en secundaria
    (Facultad de Educación. UNED, 2020) Otero-Saborido, Fernando Manuel; González-Jurado, J. A.; Vázquez Ramos, Francisco Javier
    El tratamiento que recibe la evaluación en los currículos es uno de los rasgos más relevantes debido a que sus connotaciones van más allá de la didáctica. Por ello, el objetivo de este trabajo fue analizar los aspectos evaluativos para la asignatura de Educación Física (EF) en Educación Secundaria Obligatoria comparando los 17 currículos autonómicos. Se utilizó el análisis documental de los 17 currículos a través de una herramienta validada que analizó los 1979 estándares evaluativos de las Comunidades Autónomas (CCAA). Para el análisis de resultados se aplicó estadística descriptiva con un objetivo exploratorio, técnicas correlacionales para establecer asociaciones entre variables y regresión múltiple para determinar modelos explicativos. Los resultados muestran el uso del estándar como referente evaluativo generalizado y la ausencia de orientaciones evaluativas concretas en los diferentes criterios de evaluación aplicados. El análisis exploratorio revela la prevalencia de la dimensión cognitiva (41,9%) en los estándares en detrimento de la dimensiones motriz (29,41%) y socioafectiva (28,65%). La Globalidad Educativa de los referentes evaluativos es baja (11,13%) en comparación con los que incluyen dos (26,20%) y una dimensión (62,67%). El análisis correlacional refleja relaciones directas y significativas entre la globalidad del currículo y el porcentaje dedicado a la dimensión motriz (r=0,671, p=0,003) y la eficiencia del currículo y la dimensión motriz (r=0,758; p=0,000); por otro lado, resulta una asociación inversa y significativa entre el tamaño de los currículos y la globalidad de los mismos (r=0,651; p=0,005). Los resultados de la regresión múltiple muestran dos modelos predictivos en los que la dimensión motriz explica tanto la Globalidad Educativa de los currículos (p=0,01) como su eficiencia (p=0,012). Como conclusión, parece necesario otro modelo curricular en EF menos estandarizado, con referentes más globales y que oriente al profesorado sobre prácticas de evaluación más formativas. Por último, la dimensión motriz con un carácter integrado debiera tener mayor presencia en los currículos de EF.

Physical fitness, physical activity and the Mediterranean diet (MD) are valuable tools for its prevention and treatment. The main objective of this study is to analyze the associations between health-related physical fitness components, body composition and adherence to the MD in 917 adolescents aged from 13- to 16-years-old. The ALPHA-Fitness Test was used to measure physical fitness and body composition, and the Adherence to the Mediterranean Diet (KIDMED) questionnaire was employed to assess the adherence to the MD. The associations between variables were tested according to gender and age a generalized linear model (GLM) univariate analysis (two factors) and one-way analysis of variance (ANOVA, with Bonferroni posthoc). As to the body composition and physical fitness variables, significant differences were obtained in both genders but not in relation to the adherence to the MD. The boys performed better in the physical fitness tests. Age was a determinant factor in adherence to the MD in the total sample, lowering as the age of the sample increases. Both the boys and girls who had a significantly higher performance in the endurance test were those who showed high/medium adherence to the MD. It is concluded that higher levels of cardiovascular endurance in boys and girls are associated with a medium and high adherence to the MD.
