Ítem Asociación entre la condición física y el estado ponderal en escolares de Educación Primaria(Retos: nuevas tendencias en educación física, deporte y recreación, 2024-10-21) Andrade-Lara, Karina Elizabeth; Latorre-Román, Pedro Ángel; Párraga, Juan Antonio; Pincay-Lozada, Jorge Luis; Cabrera-Linares, José Carlos; Mayanker-Lara, AlexanderLa evidencia científica señala que la condición física es un biomarcador de salud desde la primera infancia y un gran predictor de salud y hábitos saludables a lo largo de la vida. Objetivo: El objetivo del presente estudio fue conocer el nivel de condición física en escolares de 6 a 12 años en función del sexo y ciclos de Educación Primaria (EP). Un objetivo secundario fue establecer si existe asociación o no entre la condición física y el índice de masa corporal (IMC). Método: 379 estudiantes (172 niñas) de EP con edades comprendidas entre 6 y 12 años, participaron en el presente estudio de carácter descriptivo- transversal en Andalucía. Las pruebas desarrolladas fueron: velocidad 25m, Test de 20m de ida y vuelta (capacidad aeróbica) y salto horizontal (fuerza). Resultados: Se observó diferencias significativas por sexos: los niños mostraron mejor rendimiento en la prueba de capacidad aeróbica (p<0.05) y velocidad (p<0.001) con respecto a las niñas. Además, se halló diferencias significativas por sexos en los ciclos de EP. Conclusiones: Los niños muestran unos mejores niveles de condición física con respecto a las niñas en todas las variables analizadas. Además, la asociación entre la condición física y el IMC muestra que una mejor condición física correlaciona positivamente con un IMC más bajo, corroborando la importancia que tiene la condición física desde las primeras etapas como biomarcador de salud y prevención de obesidad infantil.Ítem Breastfeeding, Walking Onset, and Abdominal Obesity Are Determinants of Physical Fitness among Latin American and Spanish Schoolchildren: A Cross-Cultural Study(MDPI, 2024-06-26) Andrade-Lara, Karina Elizabeth; Cabrera-Linares, José Carlos; Párraga, Juan Antonio; Mayanker-Lara, Alexander; Lucena-Zurita, Manuel; Latorre-Román, Pedro ÁngelObjective: To comp+are levels of physical fitness between Ecuador and Spain and identify whether breastfeeding period, walking onset, and abdominal obesity are determinants of physical performance in schoolchildren from Ecuador and Spain. Methods: a total of 352 schoolchildren (6–12 years old) from Ecuador (n = 176) and Spain (n = 176) joined in this study. Anthropometric measures, socio-demographic characteristics, and physical fitness were evaluated. Results: Spanish schoolchildren showed better performance in handgrip strength, standing long jump, and 25 m sprint (p = 0.021; p < 0.001; p < 0.001; p < 0.001, respectively). Furthermore, Spanish children showed better cardiorespiratory fitness (p < 0.001) and a higher VO2 max (p = 0.002) with regards to their peers. In addition, children from Ecuador and Spain showed an influence of breastfeeding period (p ranged from <0.001 to 0.043) and walking onset (p ranged from <0.001 to 0.032) on physical performance. Moreover, physical fitness components were protective factors of abdominal obesity in Ecuadorian and Spanish schoolchildren (p ranged from =0.001 to 0.049). Conclusions: Our findings revealed the influence of the infancy period and the onset of walking on children’s physical performance, highlighting the importance of these factors in motor development during early childhood and also their influence in middle childhood and throughout adulthood.Ítem Can 16 Minutes of HIIT Improve Attentional Resources in Young Students?(MDPI, 2023-08-11) Andrade-Lara, Karina Elizabeth; Latorre-Román, Pedro Ángel; Párraga, Juan Antonio; Cabrera-Linares, José Carlosttentional resources are a cornerstone of both cognitive and academic performance. The purpose of this study was to analyse the effect of high-intensity interval training (HIIT) sessions on selective attention and visuoperceptual ability in young students. A total of 134 students (12.83 ± 1.23 years) joined this study. They were randomly assigned to a control group (CG) (n = 67), which watched a documentary, or an experimental group (EG) (n = 67), which performed 16 min of HIIT. Attention and visuoperceptual ability were assessed through the Perception of Similarities and Differences test (Caras-R test). A repeated-measures two-way ANOVA analysis was conducted. The CG showed an increased number of errors compared to the EG (p < 0.001) and showed a lower Impulsivity Control Index (p < 0.001) after the investigation. The EG, meanwhile, showed an increased number of hits (p < 0.001), Impulsivity Control Index (p < 0.001), and attentional efficacy (p < 0.001). In addition, the EG showed a decreased number of errors (p < 0.001) and omissions (p < 0.01). In conclusion, 16 min of HIIT was time-effective in improving selective attention and visuoperceptual ability in young students. These results show the importance of physical exercise and the promotion of physical activity breaks during the academic day to improve learning processes.Ítem Cantidad de pasos diarios, niveles de actividad física y su relación con la salud del adulto mayor en periodo post-pandemia(RICCAFD, 2023-12-07) de-la-Casa, Ana; Latorre-Román, Pedro Ángel; Párraga, Juan Antonio; Andrade-Lara, Karina Elizabeth; Cabrera-Linares, José CarlosEl objetivo de este estudio fue Analizar la relación existente entre el número de pasos, la frecuencia cardiaca, la calidad del sueño y las calorías medidas a diario con respecto a variables de salud, calidad de vida y nivel de actividad física en personas mayores de 60 años. Un total de 54 participantes formaron parte de este estudio (67,19 ± 9,01 años). El número de pasos, frecuencia cardiaca y niveles de sueño se registraron a través de la pulsera Xiaomi Mi Band 4.0. Las variables de salud a través de cuestionarios físicos y cognitivos. Los resultados muestran que aquellos participantes con un mayor nivel de actividad física obtienen un valor promedio más alto en las variables de físicas y cognitivas, aunque no se encontraron diferencias significativas en la comparación por sexo. En conclusión, los adultos mayores que dan más pasos semanales tienen una mejor condición física y cognitiva que aquellos que tienen un estilo de vida más sedentario. Las mujeres obtienen valores más altos en las variables físicas y cognitivas que los hombres.Ítem Effects of a dual-task activity on gait parameters of people with and without intellectual disabilities(Wiley, 2024-03-18) Cabrera-Linares, José Carlos; Latorre-Román, Pedro Ángel; Párraga, Juan Antonio; Andrade-Lara, Karina Elizabeth; Ruiz-Peralvarez, Francisco Javier; Gutiérrez-Cruz, CarmenObjective: The main objective of this study was to evaluate gait parameters in people with intellectual disability (ID) and without intellectual disability (WID) in two different walking conditions (single task vs. dual task [DT]). A secondary aim was to evaluate the dual task cost (DTC) that the DT causes in each group. Methods: A total of 119 participants joined in this study, 56 ID (30 men) and 63 WID (30 men). The Optogait system was used to assess gait. In addition, witty photocells were added to assess gait under the DT condition. Results: Single support time was lower for participants with ID (p<0.01), while double support time was higher (p<0.05). All coefficients of variation (Cv) for gait parameters were higher in participants with ID. Additionally, changes in gait were observed in both groups during the DT condition compared to the ST condition. These changes were larger for participants with ID in step length, double support time, and gait speed (p<0.001), resulting in a higher DTC in these variables in the ID group (p<0.01). Conclusion: Both groups reduced gait performance in the DT condition. However, greater gait variability occurred in the ID group. In addition, DTC was higher for the ID group in all variables analysed. Therefore, people with ID show worsening gait performance during a DT than people WID.Ítem Factors influencing gait performance in older adults in a dual-task paradigm(Springer Nature, 2024-01-08) Andrade-Lara, Karina Elizabeth; Cabrera-Linares, José Carlos; Párraga, Juan Antonio; Latorre-Román, Pedro ÁngelObjective: The aim of this study was to determine the effect of cognitive interference through a Dual Task (DT) paradigm on gait parameters by sex or other predictive variables, such as physical fitness, health status and cognitive. Methods: A total of 125 older adults joined in this study (age: 72.42 ± 5.56 years old; 28 men and 97 women). The DT paradigm was evaluated through Comfortable Linear Gait (CLG) and Complex Gait Test (CGT). Results: The gait parameters between Single task (ST) vs. DT condition in men shown a significant reduction in speed (p< 0.01), cadence (p< 0.001), Step Length (p< 0.05) and increased the time to execute the CGT (p< 0.001). While women showed a decreased speed (p<0.001), cadence (p<0.001), double support coefficient variation (CV) (p<0.05) and increased single support time (p<0.001) and CV step length (p<0.05). In addition, women increased CGT time (p<0.001). Furthermore, correlations between DT cost (DTC) cadence vs. Physical Activity for Elderly questionnaire (PASE) (r=-0.475; p <0.05), DTC single support vs. 30s Sit to Stand Test (r=0.429; p <0.05), DTC single support vs. Rey Auditory Verbal Learning Test -Learning curve (r=-0.387; p <0.05), DTC double support vs. 30s Sit to Stand Test (r=-0.590; p <0.01), DTC CV step length vs. 30s Sit to Stand (r=-0.545; p <0.01), DTC CGT vs. 30s Sit to Stand Test (r=-0.377; p <0.05) was found. Conclusions: The results of our study indicate that the gait parameters within the DT condition decreased speed and cadence, while increased CV step length and CGT time, causing slower gait with shortened steps in men and women.Ítem Reference Values in the 6-Minute Walk Test in Chilean Children Aged 3–10 Years and Relationship With Cardiometabolic Risk(Human Kinetic Journals, 2024-02-01) Latorre-Román, Pedro Ángel; Martínez-Salazar, Cristian; Párraga, Juan Antonio; Cabrera-Linares, José Carlos; Andrade-Lara, Karina Elizabeth; Robles-Fuentes, Alejandro; Espinoza-Silva, José MiguelPurpose: The aim of this study was to evaluate the performance of healthy Chilean children aged 3–10 years in the 6-minute walking test (6MWT) and cardiometabolic risk variables and to determine sex- and age-specific reference values. Methods: This study involved 1165 healthy children (age = 6.36 [1.70] y old). The 6MWT was used to evaluate exercise performance. Furthermore, anthropometric measures were collected, like weight, height, body mass index, waist circumference, and skin folds. Resting heart rate and blood pressure (BP) were also evaluated. Results: The prevalence of overweight and obesity was 35.0% and 25.4% in preschoolers and 29.0% and 36.2% in school-age children, respectively, showing significant differences (P < .05) between age groups. The distance walked (6-min walk distance) increased significantly year on year at ages from 3 to 10 years. According to the regression analysis, 6MWT performance was positively related to age, systolic BP, and height, whereas it was negatively related to ∑4 skinfold fat, resting heart rate, diastolic BP, and waist circumference. Conclusions: This study provides a reference equation and an age- and sex-adjusted percentile curve to assess the predicted 6MWT performance in a cohort of prepubertal Chilean children. The 6-minute walk distance depends mainly on age; however, other variables, such as resting heart rate, BP, skinfold fat, and waist circumference, add significant information and should be taken into account.Ítem Validation fo an Eye-Foot coordination Assessment Tool for Children in Dual - Task Condition(MDPI, 2024-12-31) Andrade-Lara, Karina Elizabeth; Serrano-Huete, Victor; Atero, Eva; Párraga, Juan Antonio; Herrador-Sánchez, Julio; Moreno-Marín, Asensio; Martínez-Redondo, Melchor; Manjón, Daniel; Salas-Sánchez, Jesús; Lucena-Zurita, Manuel; Cabrera-Linares, José Carlos; Latorre-Román, Pedro ÁngelEye–foot coordination is essential in sports and daily life, enabling the synchronization of vision and movement for tasks like ball control or crossing obstacles. This study aimed to examine both the validity and reliability of an innovative eye–foot coordination (EFC) test in a dual-task paradigm in children aged 6–11 years and the capacity of this test to discriminate between sex and age. Methods: A total of 440 schoolchildren aged 6–11 years participated in this cross-sectional study. A ball control test, involving kicking and catching, was used to assess EFC. The assessment included three conditions: without interference (WI), with auditory interference (AI), and with visual interference (VI). Results: The ICCs per the EFC test scores were 0.975 for foot successes (95% CI = 0.961–0.983; p < 0.001) and 0.747 for foot mistakes (95% CI = 0.611–0.835; p < 0.001). The SEM for the standing successes was 3.082 (10.81%), and the MDC was 4.860 (17.05%). For the standing mistakes, the SEM was 1.551 (19.33%) and the MDC was 3.452 (43.04%). Moreover, boys had a significantly higher number of successes in the WI, AI, and VI conditions (p < 0.001, respectively) than girls, although girls had more mistakes than boys only in the VI condition (p = 0.025). Conclusions: The EFC test showed adequate reliability and validity. Also, the EFC test showed that performance worsened with interference regardless of sex and age, especially in girls in the VI condition.Ítem Validation of an Eye–Foot Coordination Assessment Tool for Children in Dual-Task Condition(MDPI, 2025) Andrade-Lara, Karina Elizabeth; Serrano-Huete, Víctor; Atero, Eva; Párraga, Juan Antonio; Herrador-Sánchez, Julio; Moreno-Marín, Asensio; Martínez-Redondo, Melchor; Manjón, Daniel; Salas-Sánchez, Jesús; Lucena-Zurita, Manuel; Cabrera-Linares, José Carlos; Latorre-Román, Pedro ÁngelBackground/Objectives: Eye–foot coordination is essential in sports and daily life, enabling the synchronization of vision and movement for tasks like ball control or crossing obstacles.
