Making Every "Point" Count: Identifying the Key Determinants of Team Success in Elite Men’s Wheelchair Basketball
2019
Wheelchair basketball coaches and researchers have typically relied on box score data and the Comprehensive Basketball Grading System to inform practice, however, these data do not acknowledge how the dynamic perspectives of teams change, vary and adapt during possessions in relation to the outcome of a game. Therefore, this study aimed to identify the key dynamic variables associated with team success in elite men’s wheelchair basketball and explore the impact of each key dynamic variable upon the outcome of performance through the use of binary logistic regression modelling. The valid and reliable template developed by Francis, Owen and Peters (2019) was used to analyse video footage in S…
Programa de intervención basada en el coaching en jóvenes deportistas de alto rendimiento, y su relación con la percepción de bienestar y salud psico…
2021
El objetivo de este trabajo es el de estudiar el efecto de un programa de coaching sobre la percepción de la salud general y emocional (medido con el GHQ-12; Sánchez-López y Dresch, 2008) y el bienestar psicológico (medido con el EBP; Díaz et al., 2006) en un grupo de jóvenes atletas de alto rendimiento. Los resultados indican que el grupo experimental (n = 38), tras la realización del programa de coaching (con un promedio de 4 a 6 sesiones y 45 a 60 minutos por sesión), mejora su percepción de bienestar y salud psicológica. Estos cambios no se observan en el grupo control (n = 41). Se concluye que cuando una intervención en coaching aporta mejoras en la vida de la persona es posible que se…
‘You play like a Woman!’ Effects of gender stereotype threat on Women's performance in physical and sport activities: A meta-analysis
2018
Abstract Objectives The purpose of this quantitative review was to provide an estimation of the effect of stereotype threat on women's performance in sport. Design This review employed a meta-analytic technique. Method a meta-analysis with random effects model was performed on 24 effects. Publication bias was tested through funnel plots and Egger's regression test. Results Findings show a symmetric distribution of effects, making it possible to conclude that no file-drawer problem affected the collected sample of effects. Aggregating the results of the reviewed studies, a medium effect of stereotype threat manipulation on women's sport performances emerged (d = 0.33). Collected studies were…
Effects of a Postural Exercise Program on Vertical Jump Height in Young Female Volleyball Players with Knee Valgus
2022
Background: Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance. Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus. Methods: This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG); the Valgus Control Group (VCG); and the Neutral Control Group (NCG). All three groups carried out the same volleyball training program. In addition, only the VEG underwent a 3-month postur…
Match Load Physical Demands in U-19 Professional Soccer Players Assessed by a Wearable Inertial Sensor
2023
Background: Wearable inertial sensors are poorly used in soccer to monitor external load (EL) indicators. However, these devices could be useful for improving sports performance and potentially reducing the risk of injury. The aim of this study was to investigate the EL indicators (i.e., cinematic, mechanical, and metabolic) differences between playing positions (i.e., central backs, external strikers, fullbacks, midfielders, and wide midfielder) during the first half time of four official matches (OMs). Methods: 13 young professional soccer players (Under-19; age: 18.5 ± 0.4 years; height: 177 ± 6 cm; weight: 67 ± 4.8 kg) were monitored through a wearable inertial sens…

Association between internal load responses and recovery ability in U19 professional soccer players: A machine learning approach
2023
Background The objective of soccer training load (TL) is enhancing players’ performance while minimizing the possible negative effects induced by fatigue. In this regard, monitoring workloads and recovery is necessary to avoid overload and injuries. Given the controversial results found in literature, this study aims to better understand the complex relationship between internal training load (IL) by using rating of perceived exertion (RPE), recovery, and availability (i.e., subjective players’ readiness status). Methods In this cross-sectional study, twenty-two-professional soccer players (age: 18.5 ± 0.4 years, height: 177 ± 6 cm, weight: 67 ± 6.7 kg) competing in the U19 Italian Champion…
Experts’ successful psychomotor performance was characterized by effective switch of motor and attentional control
2019
Abstract Objectives This study proposed that Mu (8–13 Hz) and SMR (12–15 Hz) readings in the sensorimotor cortical area can be used to investigate the cognitive mechanisms underlying optimal motor performance. Design This study used a within-subject design. Method Forty expert golfers were recruited to perform 60 putts while their EEGs were recorded. The putting distance was chosen to ensure that approximately 50% of all putts would be missed so that there was a need for constant adjustments to be made during performance. Successful performance was defined as the ball going in the hole. Results (a) Lower Mu power in Cz, and alpha power in Pz and Oz were observed for successful performances …
Bus Speed Estimation By Neural Networks To Improve The Automatic Fleet Management
2007
In the urban areas, public transport service interacts with the private mobility. Moreover, on each link of the urban public transport network, the bus speed is affected by a high variability over time. It depends on the congestion level and the presence of bus way or no. The scheduling reliability of the public transport service is crucial to increase attractiveness against private car use. A comparison between a Radial Basis Function network (RBF) and Multi layer Merceptron (MLP) was carried out to estimate the average speed, analysing the dynamic bus location data achieved by an AVMS (Automatic Vehicle Monitoring System). Collected data concern bus location, geometrical parameters and tr…
