Motor development-focused exercise training enhances gross motor skills more effectively than ordinary physical activity in healthy preschool children: an updated meta-analysis.

Purpose: The growth of certain human brain structures peaks at early ages, and complex motor interventions could positively facilitate this process. This study aims to offer an updated meta-analysis regarding the effectiveness of motor development-focused exercise training on gross motor skills in preschool children. Methods: We searched English- and Chinese-language electronic databases as of March 2024. The main eligibility criteria were as follows: participants were healthy children aged 3 to 6 years old, and the experimental design was a randomized controlled trial, with the control arm participating in either free play or ordinary physical education curriculum. We conducted a Hartung-Knapp random-effects meta-analysis of the standardized mean difference for locomotor, object control, or gross motor quotient. Results: The search identified 23 eligible studies, of which approximately 75% were considered to have a low risk of bias. Compared with active control, exercise training showed a large to very large effect size. Cohen's d values were 1.13, 1.55, and 1.53 for locomotor, object control, and gross motor quotient, respectively. From a probabilistic viewpoint, these effect sizes correspond to events that are "very likely to occur" and "almost sure to occur." Due to variations in intervention programs, all outcome measures showed high heterogeneity. Conclusion: This updated meta-analysis offers a realistic synthesis of the current evidence, leading to the conclusion that targeted motor skill exercise training can almost certainly enhance preschool children's gross motor skills. Practical implications are discussed regarding the refinement of the instructional framework and the dissemination of these findings in preschool settings.

Dynamics of indicators of functional state and physical development of students in the process of high-intensity interval training.

OBJECTIVE: Aim: To investigate the effect of high-intensity interval training (HIIT) based on the CrossFit system on the level of students' functional state and physical development. PATIENTS AND METHODS: Materials and Methods: The research involved 36 male students who were engaged in HIIT during their studies. Indicators of students' functional state and physical development after 1 and 3 years of HIIT were studied. The functional state was assessed by indicators of the cardiovascular and respiratory systems, and physical development - by physical education tests. RESULTS: Results: It has been found that HIIT has a positive effect on the indicators of the functional state of the cardiovascular and respiratory systems of the body and the physical development of students. After three years of HIIT sessions, students significantly improved their heart rate, vital capacity of the lungs, Stange test, Genchi test, duration of recovery heart rate, as well as the level of development of speed qualities, strength qualities, endurance and flexibility. CONCLUSION: Conclusions: It has been established that the sports-oriented form of organization of physical education training sessions with the use of HIIT based on the CrossFit system is quite effective in improving the indicators of the functional state and physical development of students. A high level of these indicators will help to improve students' health, improve their well-being, and increase the effectiveness of their educational and, in the future, professional activities.

Integrated neuromuscular training intervention applied in schools induces a higher increase in salivary high molecular weight adiponectin and a more favorable body mass index, cardiorespiratory fitness and muscle strength in children as compared to the traditional physical education classes.

Background: High-molecular-weight adiponectin (HMW-adiponectin) is a cardio-metabolic health protector. Objectives: (1) to compare body mass index (BMI), cardiorespiratory fitness (CRF) and muscle strength (MS) in healthy school-children depending on their baseline salivary-HMW-adiponectin concentration; and (2) to apply a 3-month integrated neuromuscular training (INT) and evaluate its effects on salivary-HMW-adiponectin concentration, BMI, CRF and MS in the same children. Additional goal: to identify if any potential changes during the 3-month period may be related to a potential change in salivary-HMW-adiponectin concentration. Methods: Ninety children (7.4 ± 0.3 years) were recruited in primary schools and randomly allocated into control or intervention group. The intervention consisted of a 3-month INT applied during physical education (PE) classes, twice-weekly, while the control group had traditional PE classes. Body mass and height were measured, BMI was calculated and HMW-adiponectin was quantified in saliva. To assess CRF and MS, 800 m-run and hand-dynamometry were applied, respectively. All measurements were performed twice, at baseline and after 3 months. Results: Children with higher baseline salivary-HMW-adiponectin have more favorable BMI (p = 0.006) and slightly higher CRF (p = 0.017) in comparison to the children with lower baseline salivary-HMW-adiponectin. There were no big changes after the 3-month-period neither in the control, nor the INT group. However, it is worthy to note that the INT induced slightly higher increase in salivary-HMW-adiponectin (p = 0.007), and a slightly higher improvement in BMI (p = 0.028), CRF (p = 0.043) and MS (p = 0.003), as compared to the traditional PE classes. Finally, the INT-induced improvement in CRF was associated with the increased post-salivary-HMW-adiponectin concentration (p = 0.022). Conclusion: Main findings may suggest the potential utility of an INT as a cost-effective strategy that can be applied in schools to induce cardio-protective effects in school-children.

An experimental study on the influence of healthy physical education curriculum model on sports ability of Chinese senior high school students.

In recent years, the growing incidence of health issues among Chinese students, including obesity, diabetes, and other chronic diseases, has been attributed to a sedentary lifestyle, lack of physical activity, and unhealthy eating habits. Physical education (PE) classes play a crucial role in promoting physical activity and fostering healthy lifestyles among Chinese students. The purpose of this study was to investigate the influence of the healthy PE curriculum model on the sports ability of senior high school students in China. The trial adopted a quasi-experimental design with equivalent groups. The experimental group followed the healthy PE curriculum model in their PE classes, while the control group received traditional technical instruction. During the 12-week intervention, 149 senior high school students completed the sports ability test as both the pre-test and post-test measurements for this experimental study. The results indicated that the experimental group showed significant improvements in sports ability compared to the control group, highlighting the positive effects of the healthy PE curriculum model. The structural characteristics of the healthy PE curriculum model provided essential support for students' learning and proved to be an effective way to promote physical literacy among senior high school students in China.

An intelligent model to decode students' behavioral states in physical education using back propagation neural network and Hidden Markov Model.

This paper highlights the need for intelligent analysis of students' behavioral states in physical education tasks. The hand-ring inertial data is used to identify students' motion sequence states. First, statistical feature extraction is performed based on the acceleration and angular velocity data collected from the bracelet. After completing the filtering and noise reduction of the data, we perform feature extraction by Back Propagation Neural Network (BPNN) and use the sliding window method for analysis. Finally, the classification capability of the model sequence is enhanced by the Hidden Markov Model (HMM). The experimental results indicate that the classification accuracy of student action sequences in physical education exceeds 96% after optimization by the HMM method. This provides intelligent means and new ideas for future student state recognition in physical education and teaching reform.

A comparison of the effects of two protocols of concurrent resistance and aerobic training on physical fitness in middle school students.

Objective: This study aimed to compare the effects of two concurrent training (CT) protocols on the physical fitness of middle school students. Method: A 12-week quasi-experimental pre-test/post-test study was conducted with 157 middle school students (age = 12.48 ± 0.34, n = 90 females) divided into three groups: CT group A (CT-0h) received combined resistance training (RT) and aerobic training (AT) in each physical education session, CT group B (CT-48h) received RT and AT across two separate physical education classes 48 h apart, and a control group (Con) received no training. Training occurred twice a week. Test indicators included cardiorespiratory fitness (CRF) measured by estimated VO2max and 20 m shuttle run (laps), as well as muscle strength assessed through long jump, vertical jump, and handgrip strength. Results: The intervention groups exhibited significant increases in estimated VO2max and muscle strength compared to their baseline values (p < 0.05). Both CT-0h and CT-48h groups demonstrated significant improvements in 20 m shuttle run (laps) (mean difference: 8.88 laps, p < 0.01; mean difference: 4.81 laps, p < 0.01, respectively), standing long jump (mean difference: 6.20 cm, p < 0.01; mean difference: 3.68 cm, p < 0.01, respectively), vertical jump (mean difference: 4.95 cm, p < 0.01; mean difference: 4.04 cm, p < 0.01, respectively), and handgrip strength (mean difference: 11.17 kg, p < 0.01; mean difference: 6.99 kg, p < 0.01, respectively). CT-0h group exhibited significantly increased estimated VO2max (mean difference: 1.47 ml/kg/min, p < 0.01) compared to the CT-48h group. Conclusion: Both CT programs effectively improved adolescents' physical fitness indicators. However, the program that integrated RT and AT within the same physical education class demonstrated superior enhancement in adolescents' CRF.

Preliminary Program Evaluation of Pocket PE 3-5™, A User-Friendly Digital Application for Teacher Skills Training and Physical Education Activities for Third- to Fifth-Grade Elementary Students.

BACKGROUND: In the United States, many classroom teachers also teach physical education (PE). However, there is a dearth of evidence- and standard-based PE programs designed to support classroom teachers to deliver PE effectively in schools. METHODS: The purpose of this study was to establish proof-of-concept for the Pocket PE 3-5 digital app in school settings with 10 third- to fifth-grade classroom teachers. We assessed fidelity of program implementation, measured via observations of PE quality. Students used wrist-worn heart rate monitors during Pocket PE 3-5 lessons to measure time spent in moderate to vigorous physical activity. Program feasibility was primarily assessed through teacher-reported surveys of usability, satisfaction, and acceptability and exit interviews. RESULTS: Mean PE observation scores were 18.6 (SD = 1.5) on a scale of 5 to 20. On average, students spent 56.7% (SD = 13.1%) of class time engaging in moderate to vigorous physical activity. Mean survey scores, reported on a 5-point scale, were 4.5 (SD = 0.6) for acceptability, 4.8 (SD = 0.4) for usability, and 4.7 (SD = 0.7) for satisfaction. Teachers liked how easy the app was to use but mentioned some technological challenges. CONCLUSIONS: This program evaluation study established the proof-of-concept for the Pocket PE 3-5 elementary school PE program.

Was it a HIIT? A process evaluation of a school-based high-intensity interval training intervention.

BACKGROUND: Despite a growing body of research investigating high-intensity interval training (HIIT) in schools, there are limited process evaluations investigating their implementation. This is concerning because process evaluations are important for appropriately interpreting outcome findings and augmenting intervention design. This manuscript presents a process evaluation of Making a HIIT, a school-based HIIT intervention. METHODS: The Making a HIIT intervention spanned 8 weeks and was completed at three schools in Greater Brisbane, Australia. Ten classes (intervention group) completed 10-min teacher-led HIIT workouts at the beginning of health and physical education (HPE) lessons, and five classes (control group) continued with regular HPE lessons. The mixed methods evaluation was guided by the Framework for Effective Implementation by Durlak and DuPre. RESULTS: Program reach: Ten schools were contacted to successfully recruit three schools, from which 79% of eligible students (n = 308, x ¯ age: 13.0 ± 0.6 years, 148 girls) provided consent. Dosage: The average number of HIIT workouts provided was 10 ± 3 and the average number attended by students was 6 ± 2. Fidelity: During HIIT workouts, the percentage of time students spent at ≥ 80% of maximum heart rate (HRmax) was 55% (interquartile range (IQR): 29%-76%). Monitoring of the control group: During lessons, the intervention and control groups spent 32% (IQR: 12%-54%) and 28% (IQR: 13%-46%) of their HPE lesson at ≥ 80% of HRmax, respectively. Responsiveness: On average, students rated their enjoyment of HIIT workouts as 3.3 ± 1.1 (neutral) on a 5-point scale. Quality: Teachers found the HIIT workouts simple to implement but provided insights into the time implications of integrating them into their lessons; elements that helped facilitate their implementation; and their use within the classroom. Differentiation: Making a HIIT involved students and teachers in the co-design of HIIT workouts. Adaption: Workouts were modified due to location and weather, the complexity of exercises, and time constraints. CONCLUSION: The comprehensive evaluation of Making a HIIT provides important insights into the implementation of school-based HIIT, including encouragings findings for student enjoyment and fidelity and recommendations for improving dosage that should be considered when developing future interventions.

Effects of a 10-Week Integrated Curriculum Intervention on Physical Activity, Resting Blood Pressure, Motor Skills, and Well-Being in 6- to 7-Year-Olds.

BACKGROUND: Integrated curriculum interventions have been suggested as an effective means to increase physical activity (PA) and health. The feasibility of such approaches in children living in deprivation is unknown. This study sought to pilot an integrated curriculum pedometer intervention in children living in deprivation on school-based PA, body fatness, resting blood pressure, motor skills, and well-being. METHODS: Using a pilot cluster randomized intervention design, children (6-7 y old, n = 64) from 2 schools in central England undertook: (1) 10-week integrated curriculum intervention or (2) control (regular school-based activity). School-based PA, body fatness, resting blood pressure, motor skills, and well-being were assessed preintervention and postintervention. RESULTS: For the intervention group, PA was higher on school days when children had physical education lessons or there were physically active integrated curriculum activities. Body fatness significantly decreased, and well-being and perceived physical competence increased, pre-post for the intervention group compared with the control group. Accelerometer-derived PA, motor skills, and resting blood pressure were not significantly different pre-post for intervention or control groups. CONCLUSIONS: A 10-week integrated curriculum PA intervention is feasible to conduct and can positively impact aspects of health in 6- to 7-year-old children in England.

Research on the integrated solution of physical education based on smart campus.

To improve the physical education experience for students, this study investigates the idea of an integrated solution based on a smart campus for physical education. Within the physical education curriculum, the study focuses on the integration of smart fitness monitoring and wearables, interactive fitness equipment and gamification, mobile applications and customized workout plans, smart facilities, indoor navigation, and data-driven curriculum enhancements. The data gathered from a study involving two groups of students, an experimental group with access to smart campus solutions and a control group without such access, was analyzed using an organized and component-based framework. The data study looks at how the smart campus solutions affect the students' academic performance, fitness levels, motivation, and adherence to exercise regimens. The analyzed findings point to a few advantages of using smart campus technologies in physical education. Compared to the control group, students in the experimental group showed higher levels of academic performance, increased motivation, improved exercise adherence, and fitness. Students who had access to smart campus solutions reported much better experiences with physical education overall. The results imply that smart campus technologies have the potential to produce a physical education learning environment that is more interesting, focused on the needs of the students, and effective. Smart campus solutions help optimize curriculum design, boost motivation, and enhance academic performance by utilizing data-driven insights and personalized learning experiences.NEW & NOTEWORTHY This study investigates the idea of an integrated solution based on a smart campus for physical education.

Improving moral competence in adolescents through non-linear pedagogy in the context of physical education and sport.

BACKGROUND: The development of moral competence seems to be an important factor in the context of youth development. The problem with lack of moral competence among youth has often been observed. Physical education (PE) as a subject in school seems to provide space in the curriculum where moral development can and should be experienced and practiced. METHODS: The participants were high school students (N.=235), divided into 4 groups: two experimental and two control groups. The difference between the experimental groups was the frequency of the experiment. The first group carried out two units a week for one semester, and the second group one lesson unit throughout the school year. As a research tool the Moral Competence Test was used. RESULTS: The results indicate statistically significant positive changes between the score of Community Index (C-Index) in pretest and post-test for both experimental group (P<0.05; η2=0.04), and between pretest and follow-up in second experimental group (P<0.05; η2=0.05). Whereas in the control groups, there were no significant changes in the comparison of terms (pretest, post-test, follow-up) (P>0.05). CONCLUSIONS: Based on the study, it can be determined that the curriculum of physical education, based on the model of non-linear pedagogy, can increase the level of moral competence among young people.

Effects of School-Based High-Intensity Interval Training on Hemodynamic Parameters and Heart Rate Variability: A Randomized Controlled Trial.

ABSTRACT: Ketelhut, S, Ketelhut, K, Ketelhut, SR, and Ketelhut, RG. Effects of school-based high-intensity interval training on hemodynamic parameters and heart rate variability: A randomized controlled trial. J Strength Cond Res 38(6): 1033-1040, 2024-The purpose of this study was to assess the effects of a child-specific school-based high-intensity interval training (HIIT) implemented into physical education (PE) classes on various hemodynamic parameters and heart rate variability indices. Forty-six students (age 11 ± 1 year) were randomized into an intervention (INT n = 22) and a control group (CON n = 24). During a 12-week period, the INT and CON groups participated in regular PE twice weekly (45-90 minutes). The INT group received HIIT during the first 20 minutes of the 2 PE classes. Systolic and diastolic blood pressure, total peripheral resistance, aortic pulse wave velocity (aPWV), heart rate, SD of normal to normal heartbeat intervals, the root mean square of successive differences between normal heartbeats (RMSSD), the proportion of differences between adjacent normal to normal heartbeat intervals of more than 50 ms, low-frequency power, high-frequency power, and the LF/HF ratio were assessed before and after the experimental period. A p value ≤0.05 was considered statistically significant. Forty students (20 INT; 20 CON) were included in the analysis. A significant time × group interaction was detected for aPWV ( p = 0.05, η2 = 0.099), RMSSD ( p = 0.010, η2 = 0.161), low-frequency power ( p = 0.009, η2 = 0.165), high-frequency power ( p < 0.001, η2 = 0.272), and the LF/HF ratio ( p < 0.001, η2 = 0.354). The INT group revealed significant improvements for the respective parameters. School-based HIIT can induce improvements in cardiovascular parameters. These results highlight the potential of embedding HIIT within the school setting, offering a time-efficient exercise intervention.

A Roadmap for Sustainable Community-Engaged Partnerships in Athletic Training and Using a Traveling Athletic Training Camp as an Implementation Strategy.

Improving access to athletic trainers and increasing diversity in the profession have been major goals of the Strategic Alliance, with a particular interest in the secondary school setting. Within many marginalized communities, individuals are often faced with a lack of resources, high rates of poverty, and limited access to health care. This social and economic climate often extends to inequitable athletic training services and patterns of disparate health. Widely used and recognized strategies to cultivate diversity and address health inequities include community-engaged partnerships; however, these approaches are not well implemented across the athletic training discipline. Successful community-engaged partnerships link communities and universities, and they are rooted in intentionality to address intermediate and long-term health equity outcomes. Athletic training professionals and scholars frequently encounter gaps in resources and process-oriented methods to participate in community-engaged efforts that could include a roadmap or pathway to follow. To bridge this gap, our aims were 2-fold: (1) to disseminate a roadmap for building sustainable community-engaged partnerships in athletic training with the intent of promoting diversity, equity, inclusion, and social justice across athletic training education, research, and professional service and (2) to demonstrate how the roadmap can be implemented using a community-based athletic training education camp as an example. Implementation of the athletic training camp using the roadmap took place at secondary schools where community-engaged partnerships have been established throughout a geographic region known as the Alabama Black Belt, a region burdened with poor health outcomes, limited athletic trainer presence, and lower quality of life, exacerbated by racial and socioeconomic inequalities. Implementing this roadmap as a strategy to build sustainable community-engaged partnerships offers an innovative, interactive, and effective approach to addressing community needs by exposing secondary school students to the athletic training profession, advancing equitable athletic training research practices, and upholding and promoting the principles of diversity, equity, inclusion, and social justice in athletic training education.

Análisis no-lineal de la onda gamma del electroencefalograma en una prueba de atención e inhibición / Non-linear analysis of the electroencephalogram gamma wave in an attention and inhibition test

Introducción: Durante las últimas décadas se ha estudiado la señal del electroencefalograma desde una perspectiva de matemática no-lineal. Esto permite entender la actividad eléctrica cerebral como un sistema dinámico complejo. Objetivo: Evaluar los exponentes de Hurst y sus correlaciones en la onda gamma durante una tarea de atención alternante e inhibición de la interferencia en estudiantes universitarios. Métodos: La muestra se constituyó por 14 alumnos de educación física. Para evaluar la actividad eléctrica cerebral se utilizó el dispositivo cerebro-interfaz Emotiv Epoc®. La atención alternante se estimó con el test de símbolos y dígitos, mientras que para la inhibición de la interferencia se empleó la prueba de palabras y colores de Stroop. Resultados: En la prueba de atención alternante, cuatro individuos revelaron mayor propensión al caos en el hemisferio derecho, uno presentó más tendencia en el hemisferio izquierdo y dos no tuvieron una predisposición definida. Por otra parte, durante la prueba de inhibición de la interferencia, cinco presentaron variaciones de las medias de Hurst entre las tres láminas del efecto Stroop, sobre todo de la región temporal. Los exponentes Hurst en ambas pruebas fueron inferiores a 0,5. Conclusiones: Durante la prueba de atención se observó un mayor caos de la actividad eléctrica cerebral, sin existir correlaciones entre las regiones estudiadas. Durante la prueba de inhibición las modificaciones de los exponentes de Hurst no presentaron patrones definidos hacia el orden o caos(AU)

Introduction: During the last decades the electroencephalogram signal has been studied from a nonlinear mathematical perspective. This allows understanding brain electrical activity as a complex dynamical system. Objective: To evaluate Hurst exponents and their correlations in the gamma wave during an alternating attention and interference inhibition task in university students. Methods: The sample consisted of 14 physical education students. The Emotiv Epoc® brain-interface device was used to evaluate brain electrical activity. Alternating attention was estimated with the symbols and digits test, while the Stroop words and colors test was used for interference inhibition. Results: In the alternating attention test, four individuals revealed a greater propensity to chaos in the right hemisphere, one showed a greater tendency in the left hemisphere and two had no defined predisposition. On the other hand, during interference inhibition, variations of Hurst average values between the three Stroop effect slices were determined in five subjects, especially in the temporal region. Hurst exponents in both tests were found to be less than 0.5. Conclusions: During the attention test, a greater chaos of brain electrical activity is observed, with no correlations between the regions studied. During the inhibition test, the modifications of the Hurst exponents do not present defined patterns towards order or chaos(AU)

Consejo técnico escolar: participación virtual de los docentes de educación física de una zona escolar de Chihuahua durante la pandemia / School technical council: virtual participation of physical education teachers in a school zone in Chihuahua during the pandemic

Este estudio se enfocó en los trabajos del Consejo Técnico Escolar para explorar e identificar las temáticas, organización e interacción de los docentes de Educación Física y el posible regreso a clases. Se realizó un estudio descriptivo exploratorio con una iniciativa didáctica de micro investigación, participando 15 maestros de una zona escolar, respondiendo una encuesta de opinión. En cuanto a las formas de intervención en la educación a distancia entre los docentes mujeres y hombres, se encontraron diferencias con relación a los recursos tecnológicos y materiales apropiados (p < .025). En el manejo de las emociones de los docentes se observaron diferencias significativas en las mujeres (p < 0.028). La educación a distancia y los programas de mejora son los principales temas abordados, seguidos de la educación socioemocional y evaluación, para lo cual han tenido que desarrollar estrategias de enseñanza aprendizaje de forma remota. Se concluye que se han logrado pocos aprendizajes en la educación virtual.

This study focused on the works carried out by the School Technical Council to explore and identify the themes, organization and interaction of Physical Education teachers and their possible return to classes. An exploratory descriptive study was performed, with didactic micro-research initiative. An opinion survey was answered by 15 teachers from a school district. Regarding the forms of intervention in remote education among female and male teachers, differences were found relating to technological resources and appropriate equipment (p < .025). In regard to teachers' emotional management, there were significant differences observed in women (p < 0.028). The main topics addressed were remote education and improvement programs, followed by socioemotional education and evaluation, for which they had to develop specific strategies for remote teaching and accomplish some learning goals in remote and virtual learning.

The high-intensity interval training introduced in physical education lessons decrease systole in high blood pressure adolescents.

Increased resting blood pressure (BP) is a risk factor for many health complications. The prevalence of elevated BP is growing among adolescents. There is a need to investigate effective ways of decreasing excessive blood pressure in this age group. The study aim was to determine the effect of 10-weeks High-Intensive Interval Training (HIIT)-Tabata protocol-introduced in physical education (PE) lessons on resting blood pressure in adolescents. The sample included 52 boys aged 16.23 ± 0.33 years body height176.74 ± 6.07 (m), body weight 65.42 ± 12.51 (kg), BMI 20.89 ± 3.53 (kg/m2) and 89 girls aged 16.12 ± 0.42 years, body height 164.38 ± 6.54 (m), body weight 56.71 ± 10.23 (kg), BMI 20.93 ± 3.08 (kg/m2) from secondary school. Based on resting BP, the fractions of boys and girls with normal BP and high BP were identified and divided into experimental (EG) and control (CG) groups. EG completed a 10-weeks HIIT program (three cycles of Tabata protocol) implemented in one PE lesson during a week. The duration of the effort was 14 min. The intensity was at 75-80% of maximal heart rate. Changes in systolic and diastolic BP after the experiment were examined. The results indicated the improvement in SBP in EG with high BP compared to the rest of the groups (average reduction of 12.77 mmHg; p < 0.0001). The EG normotensive had a statistically significant higher reduction of SBP comparing CG normotensive (average decrease of 1.81 mmHG; p = 0.0089). HIIT effectively decreases BP in adolescents. Implementing HIIT in PE lessons in secondary school is recommended to improve BP parameters.
