Indicadores de carga externa e interna según el sexo durante un torneo congestionado juvenil de balonmano costarricense

Pensar mov; 22 (1), 2024
Resumen El objetivo de la investigación fue identificar los indicadores de carga externa e interna en balonmano juvenil durante un torneo congestionado en Costa Rica y determinar si existen diferencias por sexo. Se seleccionaron variables a través de Análisis de Componentes Principales (ACP) como téc...

Physiological gait test: an effective method for analyzing balance, locomotion, and neuromuscular disorders in rats and a comparison to the elevated beam test

The evaluation of animal locomotor activity is a behavioral tool widely used to measure the mechanisms underlying a particular disease, disorder, or injury, as well as the effects of exposure to a xenobiotic. The elevated beam test is one of the most used tests in rodents to assess balance and motor coor...

Efectos de la actividad locomotriz voluntaria gestacional sobre la morfología cardiaca en crías murinas

Int. j. morphol; 39 (1), 2021
RESUMEN: El objetivo del presente estudio es analizar los efectos de la actividad locomotriz voluntaria gestacional, como un tipo de entrenamiento físico, sobre la morfología de la bomba cardíaca de la cría, en modelo murino de la cepa CF-1. 12 hembras gestantes fueron divididas aleatoriamente en un ...

Locomoción humana: modelos y variables biomecánicas

Pensar mov; 18 (2), 2020
Resumen La locomoción con miembros implica diferentes desafíos de tipo mecánico: en cada ciclo, los segmentos deben reposicionarse anatómicamente, con fases de aceleración y deceleración y la consiguiente elevación y descenso del centro de masa. Dentro de la locomoción humana, la marcha y la carr...

Are cursorial birds good kinematic models of non-avian theropods?

Int. j. morphol; 37 (2), 2019
Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur locomotion. Using a comparative biomechanical approach, we found that cursorial birds h...

Instrumento de evaluación para el desarrollo en edades tempranas de Frugone y Miño

OBJETIVO: Proponer una batería para evaluar el desarrollo motor para estudiantes de primer ciclo básico. METODOLOGÍA: se evaluó una muestra de 190 estudiantes, pertenecientes a tres establecimientos educacionales de la ciudad de Talca, Chile. El rango de edad oscila entre los 5 y 9 años de edad. RES...

Leisure-Time Physical Activity, but not Commuting Physical Activity, is Associated with Cardiovascular Risk among ELSA-Brasil Participants

Arq. bras. cardiol; 110 (1), 2018
Abstract Background: Despite reports in the literature that both leisure-time physical activity (LTPA) and commuting physical activity (CPA) can promote health benefits, the literature lacks studies comparing the associations of these domains of physical activity with cardiovascular risk scores. Object...

Standardization of a spinal cord lesion model and neurologic evaluation using mice

Clinics; 73 (), 2018
OBJECTIVE: To standardize a spinal cord lesion mouse model. METHODS: Thirty BALB/c mice were divided into five groups: four experimental groups and one control group (sham). The experimental groups were subjected to spinal cord lesion by a weight drop from different heights after laminectomy whereas the...

A new approach to feed frequency studies and protein intake regulation in juvenile pirarucu

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT This study aimed to investigate pirarucu's (Arapaima gigas) ability to trigger a self-feeding system to regulate protein intake between two standard diets that contained 39% and 49% of crude protein. The same system allowed the evaluation of daily feeding and locomotor activity rhythms. Eighteen...

The preventive effects of ascorbic acid supplementation on locomotor and acetylcholinesterase activity in an animal model of schizophrenia induced by ketamine

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Studies have shown that schizophrenic patients seem to have nutritional deficiencies. Ascorbic acid (AA) has an important antioxidant effect and neuromodulatory properties. The aim of this study was to evaluate the effects of AA on locomotor activity and the acetylcholinesterase activity (AChE) ...
