Ítem Associations between Fluid Intelligence and Physical Fitness in School Children(Multidisciplinary Digital Publishing Institute (MDPI), 2024-05-10) Bazalo, Borja; Morales-Sánchez, Verónica; Pérez-Romero, Nuria; Contreras-Osorio, Falonn; Campos-Jara, Christian; Hernández-Mendo, Antonio; Reigal, Rafael E.Previous research has highlighted that active lifestyles that contribute to improved physical fitness are positively related to cognitive functioning in children and adolescents. Specifically, the increase in physical condition at school age is considered relevant because it is related to better cognitive ability and greater academic performance. Thus, the aim of this study was to analyze the relationships between explosive strength, speed–agility, and fluid reasoning in schoolchildren. To achieve this objective, an associative, comparative, and predictive design was used in this research. A total of 129 children participated in this study (age: M = 9.48; SD = 0.99). To assess fluid reasoning, the Raven test’s Standard Progressive Matrices Subtest and the Wechsler Intelligence Scale for Children (WISC-V) were used. To assess physical fitness, the speed–agility test and the horizontal jump test (ALPHA-fitness battery tests), as well as the ball throw test (2 kg), were used. The results showed that the speed–agility test significantly predicted WISC-V Fluid Reasoning Index scores, and the medicine ball toss test significantly predicted Raven test scores. The results obtained highlight the associations between physical condition at these ages and fluid intelligence. This suggests that promoting active lifestyles that improve physical fitness could have a positive impact on children’s cognitive health.Ítem Effects of a small-sided handball game on selective, sustained attention and attentional amplitude in a sample of young adults(Universidad de Murcia Servicio de Publicaciones, 2023) Reigal, Rafael Enrique; Enríquez-Molina, Rocío; Sánchez-García, Carolina; Franquelo-Egea, María Auxiliadora; Contreras-Osorio, Falonn; Campos-Jara, Christian; Hernández-Mendo, Antonio; Morales-Sánchez, VerónicaPrevious studies have highlighted the chronic and acute effects that physical exercise has on cognitive functioning. However, it is necessary to go deeper in order to obtain precise information on what type of exercise is more favorable for certain cognitive abilities. Thus, the objective of this work was to analyze the effects of a session of small games based on handball on selective, sustained attention and attention span in a sample of young adults. Fifty-two participants between the ages of 21 and 25 (M= 21.83; SD=.94) from the city of Malaga (Spain) took part in this study. A quasi-experimental intersubject's research design was used with a control and experimental group. Using non-parametric statistical analyzes (U Mann Whitney and Wilcoxon) we tried to explore the effects of the physical/sports activity session on four tests of attention span, two of selective attention and one of sustained attention. The results showed statistically significant effects on the selective tests and attention span, although not on the sustained attention test. The findings suggest that collective physical-sporting activity could have a significant acute effect on attention, although it would be necessary to continue investigating the specific dimensions of attention, given the differences found between some parameters and others. © Copyright 2018: Servicio de Publicaciones de la Universidad de MurciaÍtem Effects of Physical Exercise on Emotional Intelligence from Birth to Adolescence: A Systematic Review Protocol(Multidisciplinary Digital Publishing Institute (MDPI), 0024-12) Contreras-Osorio, Falonn; Cerda-Vega, Enrique; Campos-Jara, Christian; Ramirez-Campillo, Rodrigo; Pérez-Romero, NuriaBackground: Emotional intelligence (EI) can be understood as a set of traits or abilities that may have an impact on academic, professional, or mental health. The aim of this protocol was to establish methodological guidelines for a systematic review and meta-analysis of the effects of acute and chronic physical exercise on EI from birth to 21 years (late adolescence). Methods: This protocol followed PRISMA-P guidelines and will be modified in PROSPERO after peer review. The review will include experimental randomized and non-randomized control studies involving physical exercise interventions. PubMed, Web of Science, Scopus, and EBSCO will be utilized for study selection following the publication of the protocol. The risk of bias will be assessed using the ROBINS-I tool, ROB-2, and the GRADE approach will evaluate the certainty of evidence. Random effect meta-analyses will analyse the effect of physical exercise compared with control groups, using effect sizes measures (Hedges’ g), with a 95% confidence interval and prediction interval, for each EI outcome (perception, facilitation, understanding, regulation, and management of emotions). Potential moderators, such as exercise intensity, duration, and sociocultural factors, will be analysed. Heterogeneity will be assessed using the I2 statistic, and sensitivity analyses will be performed to ensure result robustness. Subgroup analyses may be conducted based on age groups and specific EI dimensions. Conclusions: Publication bias will be assessed using Egger’s test and the trim-and-fill method. The future results aim to provide a foundation for analysing the impact of physical exercise on EI development, potentially guiding future interventions in health, educational, and related fields. © 2024 by the authors.Ítem Effects of physical exercise on executive functions of individuals with schizophrenia spectrum disorders: Protocol for a systematic review and meta-analysis(Public Library of Science, 2024) Pérez-Romero, Nuria; Campos-Jara, Christian; Pesce, Caterina; Sierralta, Sergio Araya; Cerda-Vega, Enrique; Ramirez-Campillo, Rodrigo; Campos-Jara, Rodrigo; Martínez-Salazar, Cristian; Arellano-Roco, Cristián; Contreras-Osorio, FalonnIntroduction Executive functions are commonly impaired in individuals with schizophrenia spectrum disorders. Physical exercise has the potential for improving executive functions and can be easily implemented as a therapeutic method. However, there are only few systematic reviews of exercise effects in schizophrenia including cognitive outcomes, and no meta-analytical syntheses of effects on “cool” and “hot” executive functions. The purpose of this systematic review and meta-analysis will be to determine the effects of physical exercise on “cool” and “hot” executive functions of adults with schizophrenia spectrum disorders. Methods and analysis This protocol was guided by PRISMA-P guidelines. Studies will be searched using combinations of keywords and medical terms in the Web of Science, PubMed, Scopus, and EBSCO databases. Inclusion criteria will be determined as per PICOS approach. The risk of bias will be assessed using the Cochrane RoB2 tool. The certainty of evidence (per outcome) will be assessed using the GRADE method. The meta-analyses will be performed using the DerSimonian and Laird random effects model. Effect sizes (Hedges’ g) with 95% confidence intervals will be calculated for each main outcome. Conclusions The results of this review may be useful for mental health professionals to design treatment plans for adults with schizophrenia spectrum disorders, offering potential benefits related to the quality of life and cognitive abilities of this population. © 2024 Public Library of Science.

Revisión de la literatura(Universidad Nacional de Colombia, 2018-07) Villarroel-Bustamante, Karin; Jérez-Mayorga, Daniel Alejandro; Campos-Jara, Christian; Delgado-Floody, Pedro; Guzmán-Guzmán, Iris PaolaIntroduction: Idiopathic pulmonary fibrosis (IPF) is an interstitial, chronic and progressive disease that usually appears with dyspnea and progressive deterioration of exercise tolerance and activities of daily living, compromising psychological well-being and social interaction. Objectives: To select and summarize information about functional capacity response, pulmonary function and health-related quality of life in patients with IPF after being subjected to a pulmonary rehabilitation program. Materials and methods: Literature review from 2000 to 2016, using the PubMed and ScienceDirect databases. Results: 10 randomized clinical trials were selected. A tendency to a significant increase in the distance traveled in the 6-minute walk test was found. Regarding pulmonary function, results were variable among the studied populations. Quality of life related to health improvement was observed in all patients undergoing rehabilitation, but dyspnea levels showed discordant results. Conclusion: The trials show benefits in terms of functional capacity and health-related quality of life; however, studies are still scarce, done on small populations, and the effects of rehabilitation programs are not sustained 6 months after post-training evaluation. © 2018, Universidad Nacional de Colombia.

This study aimed 1) to describe and compare the HR during exercise between HTN and normotensive adults and 2) to describe the endothelial function and related vascular parameters in both groups. A descriptive clinical study was conducted with 64 adults (men and women) who were divided into three groups: arterial hypertension (HTN n=26), elevated blood pressure (Ele n=16), or normotensive control (CG n=22). The participants underwent an incremental cycling exercise test of 5 stages, where HR (primary outcome) was measured, and secondary vascular outcomes (percentile classification of the pulse wave velocity (%ILEPWVba), maximum carotid intima-media thickness (cIMTmax), and arterial age among others were measured. In stage 2 of the test (50-100 watts), the HTN group showed significantly higher HR vs. CG (+14 beats/min; p<0.05) and vs. Ele group (+15 beats/min; p<0.05), and in stage 5 (125-250 watts), HTN group showed higher HR vs. CG (+22 beats/min; p<0.05). HTN group showed a higher arterial stiffness by %ILEPWVba classification and arterial age estimation than the CG group. In conclusion, HTN patients reported a higher HR response only in two out of five (monitored) stages of the Astrand cycling exercise test than normotensive peers. Moreover, all groups showed a higher HRpredicted than real HRpeak obtained from the exercise test. These results are displayed with more altered vascular parameters in the HTN group. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF)Ítem Lifestyle and cardiometabolic risk factors in the ethnic and non-ethnic population > 15 years of age: results from the National Chilean Health Survey 2016-2017(ARAN Ediciones S.L, 2023-03) Álvarez, Cristian; Ramírez-Campillo, Rodrigo; Miranda-Fuentes, Claudia; Ibacache-Saavedra, Paulina; Campos-Jara, Christian; Cristi-Montero, Carlos; Molina-Sotomayor, Edgardo; Caparrós-Manosalva, Cristian; Delgado-Floody, PedroBackground: lifestyle and cardiometabolic risk factors information is scarce regarding youth and adults of Latin-American ethnics. Objective: the primary aim was to describe the lifestyle and cardiometabolic risk factors for arterial hypertension (HTN) and diabetes in ethnic Latin-American groups (Mapuche and Aymara) and other non-ethnics > 15 years of age in the Chilean population. A secondary aim was to determine the association between physical activity ‘intensity’ with HTN and diabetes markers. Material and methods: a representative sample from the National Chilean Health Survey 2016-2017, included Mapuche (EG-Map; women n = 166, men n = 300; total n = 466), Aymara (EG-Aym; women n = 96, men n = 55; total n = 151), and a non-ethnic population group (No-EG; women n = 2057, men n = 3445; total n = 5502). The main outcomes were; systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (GL), and secondary outcomes were other anthropometric, lipid profile, and lifestyle parameters. Results: GL was significantly associated with nutrition (0.9 %, p < 0.0001), tobacco and alcohol habits (0.6 %, p < 0.0001). SBP was significantly associated with nutrition (whole-grains 0.04, p = 0.001; water consumption 0.07, p < 0.0001), sleep hygiene (week 0.04, p = 0.030; on weekends-0.04, p = 0.026), and alcohol consumption (-0.06, p < 0.0001). Conclusion: in conclusion, lifestyle differences among Mapuche and Aymara ethnic groups in comparison with non-ethnic Chilean peers > 15 years are significantly associated with blood pressure and glycemia. © 2023 SENPE y©Arán Ediciones S.L.Ítem Regional fat changes induced by localized muscle endurance resistance training(Lippincott, Williams & Wilkins, 2013-08) Ramírez-Campillo, Rodrigo; Andrade, David C.; Campos-Jara, Christian; Henríquez-Olguín, Carlos; Alvarez-Lepín, Cristian; Izquierdo, MikelThe purpose of this study was to examine the effects of a localized muscle endurance resistance training program on total body and regional tissue composition. Seven men and 4 women (aged 236 1 years) were trained with their nondominant leg during 12 weeks, 3 sessions per week. Each session consisted of 1 set of 960-1,200 repetitions (leg press exercise), at 10-30% 1 repetition maximum. Before and after training, body mass, bone mass, bone mineral density (BMD), lean mass, fat mass, and fat percentage were determined by dual-emission x-ray absorptiometry. Energy intakes were registered using a food recall questionnaire. At the wholebody level, body mass, bone mass, BMD, lean mass, or body fat percentage were not significantly changed. However, body fat mass significantly decreased by 5.1% (preexercise: 13.5 6 6.3 kg; postexercise: 12.8 ± 5.4 kg, p < 0.05). No significant changes in bone mass, lean mass, fat mass, or fat percentage were observed in both the control and trained leg. A significant (p < 0.05) decrease in fat mass was observed in the upper extremities and trunk (10.2 and 6.9%, respectively, p < 0.05). The reduction of fat mass in the upper extremities and trunk was significantly greater (p < 0.05) than the fat mass change observed in the trained leg but not in the control leg. No significant changes were observed in energy intake pre- and postexercise intervention (2,646 ± 444 kcal$d21 and 2,677 ± 617 kcal$d21, respectively). In conclusion, the training program was effective in reducing fat mass, but this reduction was not achieved in the trained body segment. The present results expand the limited knowledge available about the plastic heterogeneity of regional body tissues when a localized resistance training program is applied. © 2013 National Strength and Conditioning Association.
