An important step to enhance the academic efficiency of students is increasing their physical activity. For this reason, it is necessary to see to what extent physical activity is related to the academic performance of the students and what might mediate this. A major objective of the study is to explore self-esteem and depression as mediators between physical activity and academic performance. On the basis of informed consent to participate in the study, 358 participants have been selected from Universities in Pakistan, and they were asked about their physical activity, depression during their study and self-esteem through self-report. Participants self-reported their self-esteem, level of depression and their physical activity through standardized measures; the Rosenberg Self-esteem scale (1965), the University stress scale (2016), and the short form of the International Physical Activity questionnaire (2003), respectively. Academic performance had been measured as the cumulative grade point average (CGPA) of the last two consecutive semesters. Self-esteem and depression were found to be significant mediators between physical activity and academic performance. The total effect of physical activity on academic performance was significant but smaller than the total indirect effect through mediators. Though total indirect effect is the combination of the effect of self-esteem and depression, but the larger contribution is of self-esteem which has been found to be the strongest mediator between physical activity and academic performance. The study has implications for future research, both in terms of testing the model and testing psychological constructs. Also, the study emphasizes that the importance of physical activity has to be kept in mind while designing a curriculum of an educational institution in order to foster sustainable development.

The COVID-19 pandemic has impacted the lives of many people. Objective: The aim of the present study was to analyse the physical activity (PA) and daily routine among children (0–12 years) during lockdown and to establish the main relationships among the variables. Methods: A quantitative study with a descriptive–comparative and cross-sectional design carried out. The sample, selected for convenience, consisted of 837 Spanish children aged 0–12. The “Children and confinement” questionnaire was used, distributed electronically through Google Forms and social networks and activated for 45 days. The individuals participating in this study were mainly children (50.2%) who were in primary education (44.8%). Predominantly, the families of participants were biparental (87.9%), with established routines and schedules (85.7%). Results and conclusions: The use of digital screens is an important part of children’s daily routine. Their daily activities were practiced for more than three–six years, with more by girls. The time children devoted to sleep was directly proportional to the time they devoted to physical activity and indirectly proportional to the time they spent watching screens. The children who slept the most were those aged zero–three years, especially girls, who belonged to large families. The levels of physical activity in the sample were low, as were the times spent on activities such as music or games.

Adolescence is a transformative period in which rapid physical, cognitive and psychosocial growth takes place. Laying the foundation for healthy behaviors is paramount during these formative years. The aim of this review is to determine which countries are leading in research on adolescents’ motivation towards physical activity and healthy habits and their main findings. A systematic review was conducted following the PRISMA statement using the Web of Science and Scopus databases during the months of September to December 2022. The search terms used were: “Physical activity”, “Motivation” and “Adolescents”, in the following research areas: Education, Educational Research and Sport Sciences. A total of 5594 articles were identified, but only those that met the established criteria were included (32 articles). It is concluded that most of the research is led in Spain with 16 articles, followed by 3 in Chile, 2 in Portugal, 2 in Norway and the rest of the countries with 1. Likewise, most of the works include very similar aspects regarding the incidence of motivation towards the adherence to the practice of Physical Activity and healthy habits.

Introducción: Las TIC están presentes en muchos hogares estableciendo cambios en la comunicación social y estilo de vida. En el año 2020 se ha declarado en España el estado de alarma con un importante periodo de confinamiento debido a la aparición de una nueva pandemia mundial COVID-19. A través de este trabajo se realiza una radiografía del equipamiento y uso de las TIC en los hogares españoles con niños menores de 12 años durante el periodo de confinamiento y cómo ese tiempo y las TIC han influido en los hábitos sociales de los niños, su estilo de vida y nivel de actividad física. Metodología: Se realizó una investigación cuantitativa con un diseño no experimental, de carácter descriptivo, comparativo y correlacional, con una única medición en un solo grupo. La muestra estuvo compuesta por 837 niños españoles menores de 12 años. Resultados: Se confirma un número importante de dispositivos electrónicos en los hogares, tiempos de uso diferentes para cada uno y la existencia de diversas correlaciones entre TIC y hábitos sociales y de estilo de vida de los niños. Discusión: Otros trabajos confirman valores similares de dispositivos electrónicos en los hogares, así como el sobreuso de algunos de ellos en detrimento de la actividad física. Conclusiones: El periodo de confinamiento ha provocado cambios notables en el estilo de vida de los niños y sus hábitos sociales. La presencia de un mayor o menor número de TIC en el hogar y su uso puede influir en otras actividades realizadas por los niños.

The period of confinement motivated by the COVID-19 pandemic and established by the governments of different countries has influenced the lifestyle of millions of children, not being able to continue carrying out multiple educational activities as they did until confinement. The objective of this research was to determine and analyze whether the living conditions of children during the period of confinement caused by COVID-19 influenced their daily educational activities. A descriptive, comparative and cross-sectional quantitative study with a non-experimental design was carried out, with a single measurement in a single group. Factors associate with living conditions were analyzed, such as the place of residence and the type of house in which Spanish children have been confined, as well as the number and use of technological devices. The parents' perception of the children's state of fatigue, happiness, energy and tiredness was also analyzed. We have worked with a sample of 837 Spanish children. As a data collection instrument, the validated questionnaire on Equipment and Use of Information and Communication Technologies in Households (TIC-H2019) of the National Statistics Institute (INE) was used, following the recommendations of the Statistical Office of the European Union (EUROSTAT).

The aim of this study was to describe the characteristics of jump capacity in a group of secondary school students and to develop 2 specific equations-applied to boys and girls, respectively, to estimate the jump power of secondary school students. Four hundred and fifty-six boys (age, 14.1 ± 0.8 years; mass, 61.9 ± 15.7 kg; height, 1.64 ± 0.10 m) and 465 girls (age, 14.1 ± 0.9 years; mass, 55.1 ± 10.0 kg; height, 1.58 ± 0.07 m), all of them secondary school students, volunteered to participate in this study. They performed a vertical jump test (Abalakov) on a force platform, and jump height and peak power were measured. Most importantly, peak power was also estimated through a series of previously established power equations. For the purpose of establishing statistically significant differences, a p value ≤ 0.05 was fixed. The equations proposed by Canavan and Vesconvi, and Harman were the most precise with respect to actual power, reaching a percentage of 1.9-2.1 and 3.6-4.1%, respectively. The equations by Sayers and Lara showed a greater difference in percentage (9.9-12.4 and 22.4-24.2%, respectively) with that of actual power. Similar results were not obtained in other studies, which means that a specific equation will be required according to the characteristics of the assessed sample. Two equations specifically addressed to secondary school students will be established in this article: boys: ([61.8 jump height (cm)] + [37.1 body mass (kg)] - 1,941.6); girls: ([31 jump height (cm)] + [45 body mass (kg)] - 1,045.4). Crossvalidation tests that were done to prove the validity of said equations showed positive results. Practical applications: Those teachers who wish to estimate the jump power of their pupils can use these equations and thereby calculate jump power by the indirect method from jump height and body mass index, without any need to use any expensive tools.
