    Tell me how much your opponent team runs and I will tell you how much you should run: A predictive model applied to Spanish high-level football
    (Institute of Sport – National Research Institute, 2024) Castellano, Julen; López-Del Campo, Roberto; Hileno González, Raúl
    The aim of this study was to predict a team’s accumulated distance (TotDisTea) and accumulated distance at > 21 km/h (TotDis21Tea) in the Spanish Football First Division. 2,946 team physical performances (out of 3040 possible) during four seasons (from 2016–17 to 2019–20) were analysed. The outcome variables were the TotDisTea and TotDis21Tea when the ball was in play. Eight predictor variables were used: the distance accumulated and accumulated at > 21 km/h by the opponent (TotDisOpp and TotDis21Opp) were registered in km, the effective playing (EffPlaTim) and possession (BalPos) time were recorded in min, match location (MatLoc) had two levels (home and away), match outcome (MatOut) had three levels (lost, drawn, and won), and the teams were grouped in four levels (Champions League, Europa League, remained, and relegation) distinguishing the observed team (TeaLev) and the opponent team (OppLev) in the match. A total of 127 models were estimated from the all-possible regressions procedure for each outcome variable. The model with six predictor variables was selected as the best model to predict the TotDisTea (R2adj = .82). The predictor variables TotDisOpp, EffPlaTim, and BalPos had a greater contribution to the mean outcome value than the predictors OppLev, TeaLev, and MatLoc. All models estimated to predict TotDis21Tea had little predictive power (R2adj < .38). The findings of this study have both theoretical and practical implications for practitioners. The interaction between teams has a great effect on the conditional response. Before the match, teams could use this information to anticipate the physical demand expected in the next match, and after the match, be able to assess whether the physical response was similar to expected, and make decisions.

    Body morphology and handgrip strength parameters of the female canoe slalom paddlers
    (Frontiers Media, 2024) Busta, Jan; Hellebrand, Jaroslav; Kinkorová, Ivana; Duchoňová, Andrea; Hybská, Tereza; Costa Sánchez, Carmen; Vajda, Matej
    Introduction: Canoe slalom is a physically very demanding discipline, in which body constitution, body composition, and relative strength are significant factors in high performance. Although anthropometric and strength parameters are relatively well-studied in male athletes, there is a lack of evidence for any conclusions in women. Therefore, the objective of this study was to determine the morphology and upper-limb strength parameters of female canoe slalom paddlers and identify whether morphological differences exist between performance groups. Methods: Altogether, 63 female competitors of the 2023 ICF Canoe Slalom World Cup (n = 29) and 2023 ICF Canoe Slalom World Ranking Competition (n = 34) in Prague (Czech Republic) were examined with a battery of anthropometric tests, segmental bioimpedance analysis, and handgrip strength test. The athletes were divided into groups according to age and performance: elite athletes belonging to the world top 10 according to the ICF World Ranking (WORLD, n = 7), international-level athletes competing during the World Cup (ELITE, n = 22), international-level junior athletes competing in the World Ranking Race (JUNIOR, n = 17), and other lower performance-level athletes competing in the World Ranking Race (REST, n = 17). Results: Female slalom paddlers are, in general, of average body height (∼165 cm), lower body mass (∼60 kg), BMI (∼22 kg/m2), and body fat (∼20%) and without exceptional anthropometric dimensions and proportions. However, differences were detected when performance was factored in. Female paddlers belonging to the world TOP 10 have the largest circumferences of arms and forearms, and their somatotype is more mesomorphic, with a lower proportion of total body fat and a higher proportion of muscle mass. In addition, the WORLD group differs significantly in upper-limb strength. Discussion: The results shows the significance of muscular strength and power for canoe slalom athletes and the importance of well-developed musculature in operating the boat in the unstable environment. Being a successful female canoe slalom athlete requires a well-developed musculature, maximizing strength capabilities while maintaining a low body weight through limited hypertrophy of the lower limbs and a low level of body fat.

    Effects of Hypopressive Exercise on Dynamic Neuromuscular Control in Female Roller-Skaters
    (Berkeley Electronic Press, 2024) Hernández-Rovira, Esther; Rial Rebullido , Tamara; Alonso-Aubin , Diego A.; Cañabate Ortiz, Dolors
    The effects of hypopressive exercise (HE) on dynamic balance have never been studied. We aimed to study the effects of a HE program on dynamic balance, posterior chain kinematics and expiratory peak flow on female competitive roller skaters over a 6-week training period. Twenty competitive female roller-skaters (13-22 years of age, SD 2.25) performed a 30-minute HE session once weekly before the regular roller-skating practice for 6 weeks. The HE program consisted of breathing and postural awareness exercises in addition to 5 basic HE poses performed three times each. Dynamic neuromuscular control was assessed with the Y-Balance Test (YBT), posterior back chain kinematics with the sit and reach test and peak expiratory flow rate with a digital spirometer. Paired t-test revealed significant differences between the measurement periods for all YBT leg directions and composite score (p ≤ 0.01). Significant differences were also revealed between baseline and after the intervention for the sit and reach test (p ≤ 0.01) and peak expiratory flow (p = 0.01). No differences in forced expiratory volume in the first second were found (p = 0.04). These preliminary findings suggest that a 6-week HE program could be a feasible neuromuscular option for training dynamic balance, posterior back chain kinematics and peak expiratory flow in female roller-skaters.

    Transfer of learning factors model applied to in-service teachers of early childhood care and education in Puebla, Mexico
    (Universitat Autònoma de Barcelona, 2024) Villaseñor, Karla; Torrelles Nadal, Cristina; Silva-Ríos, Carlos; Quesada Pallares, Carla
    Research has shown that early childhood care and education (ECCE) can improve chil-dren’s development. Training of in-service teachers is a good strategy to maximize the quality of ECCE, but in Mexico, teachers consider that in-service training is not par-ticularly relevant. To counter this tendency, The Mexican Educational System designed and implemented an in-service training policy. The aim of this study was to analyse the impact of individual factors on learning transfer during the COVID-19 pandemic. It followed a longitudinal, non-experimental design. Two instruments were applied at different times. In May 2021, during the COVID-19 lockdown, the Puebla Ministry of Education offered five online courses aimed at early childhood and preschool teach-ers. 6,562 teachers enrolled, but only 2,865 successfully completed the courses. Upon completion of the courses, we applied the transfer of learning factors model (Quesada-Pallarès et al., 2018). The model predicted that teachers devise plans and strategies for applying the contents learned, guided by their own desire to transfer. In this regard, it might be asserted that the will to transfer is steered by teachers’ autonomous drive to transfer.

    Gamification to Engage Healthy Habits in Socially Deprived Secondary School Students
    (Federación Española de Asociaciones de Docentes de Educación Física (FEADEF), 2024) Rodríguez-Ferrer, José Miguel; Manzano-León, Ana; Tadeu, Pedro; Camacho Sánchez, Rubén; Aguilar-Parra, José M.
    A sedentary lifestyle, unhealthy eating habits, and substance abuse are increasingly prevalent among adolescents, necessitating effective interventions within educational environments. This study aimed to assess the effectiveness of a fifteen-week gamified intervention to promote healthy habits among 314 secondary school students residing in socially deprived areas. The gamified PBL (Points-Badges and Leaderboard) approach offers a promising strategy to engage students, enhance their knowledge, and influence their physical activity, nutrition, and substance consumption behaviors. Employing a pre-post-test design with a control group, data were collected through Kimed and IPAQ questionnaires evaluating participants' habits. Results revealed statistically significant differences between pretest and post-test scores in the experimental group and significant differences favoring the experimental group. Participating students exhibited improved physical activity and nutrition, alongside a reduction in harmful substance consumption behaviors. These findings suggest that the gamified PBL intervention holds promise in promoting healthier habits among secondary school students, specifically in socially deprived areas, emphasizing the importance of integrating such interventions into educational curricula.
