Predictors of batting and pitching performance in the USA baseball prospect development pipeline.

This study examined the relationship between psychomotor abilities and baseball performance by analysing data from 379 athletes who participated in the USA Baseball, Prospect Development Pipeline (PDP). Hit and pitch metrics were generated during practice sessions using the RapsodoTM System. Data were compared through exploratory factor analysis and hierarchical regression. Factor analysis grouped batter's PDP evaluations into four latent variables accounting for 63% of variance. Pitcher performance grouped into three factors accounting for 51% of variance. Regression on batter data revealed a significant demographic/anthropometric base model with height, weight, and age that accounted for 58% of the batted ball speed (R2 = 0.581). Player position explained 2% of the variance (R2 = 0.604), and PDP evaluation scores contributed an additional 3% (R2 = 0.631). Regression of pitcher data showed a significant base demographic/anthropometric model accounting for 36% of fastball pitch speeds (R2 = 0.363), with the PDP evaluation scores adding 6% additional variance (R2 = 0.424). Uniformly, assessments of lower body strength added the greatest predictive information. Hand grip strength did not correlate with pitch metrics. While demographics/anthropometrics are major contributors to batted and pitched ball speed, position and psychomotor variables add statistically significant contributions and may be of practical value for player selection.

Cognitive function and impact on driving after SARS-COV-2 infection in a man with long-standing HIV infection: a case report.

A substantial number of individuals who experience COVID-19 infection experience prolonged physical and mental symptoms after resolution of their initial infection, and among them, many individuals experience cognitive difficulties including memory lapses and executive function difficulties, often referred to as "brain fog." The possible impact of COVID-19 infection on cognition in persons with HIV-related cognitive disorders is unknown. In this report, we describe post-COVID-19 cognitive and driving function in a 62-year-old man with HIV infection since the early 1990s.

Capacidades psicomotoras e índice de masa corporal en escolares de 6 a 10 años de Colombia / Psychomotor capabilities and body mass index in school children from 6 to 10 years old in Colombia

Las capacidades psicomotrices son inherentes en el desarrollo del ser humano. Un estado nutricional inadecuado conlleva a que las niñas y niños presenten dificultad en los movimientos motores. El objetivo fue determinar el perfil del de las capacidades psicomotor y su la correlación con el índice de masa corporal (IMC) en niños de 6 a 10 años de primaria del municipio de Sabanalarga, Atlántico, Colombia. Fue un estudio de corte transversal y correlacional, la población se conformó por un total de 416 niños matriculados en la jornada vespertina, tomando como muestra 210 niños de primero a quinto grado; de los cuales, 108 son del sexo masculino y 102 del sexo femenino, siendo establecidos por conveniencia. La evaluación de las (CPS) se hizo con la batería del test perceptivo motriz de Jack Capón (adaptado por Sergio Carrasco, 1989) y para establecer los niveles del IMC se empleó los protocolos para niños definidos por la OMS (2007). Los datos se organizaron en el programa Excel 2016 y analizados en el software estadístico PSPP versión gratuita 1.2. Los resultados muestran que los niños de 10 años presentaron deficiencia en las (CPS) con el 66,9% seguido de los niños de 8 a 9 años con el 62,9%; un mínimo de niños de 6 años con el 33.8%, con diferencia significativa (p<0,05); se encontró prevalencia de niños con normopeso. Sin embargo, el 25.9% de niños presenta sobrepeso/obesidad más que las niñas con el 17,6% (p<0,05), llama la atención que 2,9% de niñas y el 4,6% de niños tiene delgadez. Al analizar las (CPS) con el (IMC) se encontró que los niños con sobrepeso/obesidad y riego de delgadez tiene bajo rendimiento en las pruebas (1, 2, 3 y 4), no se halló diferencia estadística significativas (P >0,05), excepto la prueba 5 recorrido de obstáculo (p <0,05).

Psychomotor abilities are inherent in the development of the human being. An inadequate nutritional status leads to girls and boys having difficulty in motor movements. The objective was to determine the profile of psychomotor abilities and its correlation with the body mass index (BMI) in children aged 6 to 10 years of primary school in the municipality of Sabanalarga, Atlántico, Colombia. It was a cross-sectional and correlational study, the population was made up of a total of 416 children enrolled in the evening shift, taking as a sample 210 children from first to fifth grade; of which, 108 are male and 102 female, being established for convenience. The evaluation of the (CPS) was done with the Jack Capón perceptual motor test battery (adapted by Sergio Carrasco, 1989) and to establish the BMI levels, the protocols for children defined by the WHO (2007) were used. The data was organized in the Excel 2016 program and analyzed in the statistical software PSPP free version 1.2. The results show that children aged 10 years presented deficiency in the (CPS) with 66.9% followed by children aged 8 to 9 years with 62.9%; a minimum of 6-year-old children with 33.8%, with significant differences (p<0.05); prevalence of children with normal weight was found. However, 25.9% of boys are overweight/obese more than girls with 17.6% (p<0.05), it is noteworthy that 2.9% of girls and 4.6% of boys are thin . When analyzing the (CPS) with the (BMI) it was found that children with overweight/obesity and risk of thinness have low performance in the tests (1, 2, 3 and 4), no significant statistical difference was found (P > 0 .05), except the obstacle course test 5 (p <0.05).

Characteristics of Cognitive Abilities among Youths Practicing Football.

The aim of the study was to assess selected cognitive abilities depending on age, anthropometric parametres, physical fitness and technical skills in the group of young players training football. The study covered a group of 258 young players practicing football (age: 12.1± 2.03), who were divided into 5 age categories (8-9 years old, 10-11 years old, 12-13 years old, 14-15 years old, 16-17 years old). Selected cognitive abilities include: simple reaction time (SIRT), complex reaction time (CHORT), hand-eye coordination (HECOR) and spatial orientation (SPANT). Studies were performed using Test2Drive computer tests. In addition, the level of physical fitness was measured using: The standing long jump, 30 m sprint, 20 m shuttle run test (without and with the ball) and slalom (without and with the ball). The analysis showed a statistically significant relationship between age and cognitive abilities. There was also a statistically significant correlation between fitness tests and reaction time in individual cognitive tests. There were no statistically significant relationships between technical skills and cognitive abilities. The study confirms that age and physical fitness affect the level of cognitive abilities.

The elements of executive attention in top soccer referees and assistant referees.

The aim of the present study was to compare executive attention of top soccer referees and assistant referees at different levels of professional attainment. The sample consisted of 53 subjects (FIFA and national level) - 30 referees and 23 assistant referees. Executive attention of assistant referees was significantly better than the referees' (p<0.01). Furthermore, extraclass and international referees demonstrated better executive attention than the first-league referees (p<0.01). The research results have proved that referees' executive attention differs depending on their function and professional level, as well as indicated that the quality of abilities may influence the number and correctness of decisions made during a game. This elementary cognitive process may be strongly shaped by individual's experience and age. This finding may be instrumental in screening referees and developing criteria for recruiting future referees.

Cognitive retardation in a patient with preservation of psychomotor speed.

We describe a patient (R.S.) who after a bout of probable TB exhibited an unusual pattern of response retardation, although given time he was able to score at a satisfactory level. He was strikingly slow to initiate speaking and to carry out higher level cognitive tasks, at a time when he could complete a variety of psychomotor activities at normal speed. He showed many similarities with patients previously described as having subcortical dementia. The selective preservation of psychomotor responding in the context of his gross bradyphrenia, however, was unexpected.
