The aim of this study was to determine whether ownership and use of electronic media were associated with sedentary time and cardiorespiratory fitness (fitness) in youth. We also aimed to determine if associations were independent of physical activity (PA).Fitness was measured using the 20 m shuttle-run. PA, sedentary time, ownership of media devices and media use were self-reported.Participants (n = 678, age 10–15 years) reported daily sedentary time of 620 (± 210) min. Forty-one percent of participants had low PA and 50.4% had low fitness.Higher weekend sedentary time was associated with low fitness in girls (p = 0.005) and boys (p < 0.001) and remained significant when adjusted for PA in the latter (p = 0.006). Using social media was associated with higher sedentary time in both sexes and low fitness in girls. High sedentary time was more likely (OR = 5.3, 95%CI: 2.0–14.4) in boys who owned game consoles. Low fitness was more likely in boys who owned digital/satellite TV receivers (OR = 1.8, 95%CI: 1.8–3.2).Schoolchildren spent > 10 h or ~ 85% of each waking day sedentary. Use of social media was associated with higher sedentary time in both sexes and with low fitness in girls. Reducing social media use in youth offers one potential target for intervention. Behaviours associated with sedentary time differed from predictors of low fitness. The complex and often sex-specific interactions identified between sedentary time, PA and fitness suggest the need for carefully targeted interventions to reduce sedentary time and improve fitness in English youth.

IntroductionThe aim of this research is to identify the effect of Small-sided games using the FITLIGHT training system on some of the harmonic abilities and some of the basic skills of basketball Players.MethodsThe researchers used the experimental method on 24 basketball players. They were randomly divided into two groups: one experimental (n = 12, age = 10.92 ± 0.79 years; height = 138.50 ± 2.78 cm; weight = 40.25 ± 2.01 kg) and a control group (n = 12, age = 11.17 ± 0. 72 years; length = 139.92 ± 3.53 cm; weight = 40.50 ± . 1.73 kg). The homogeneity between the two groups was calculated and showed that there were no differences between the two samples. In the research variables, the proposed program was applied for 10 weeks at the rate of 4 weekly training units.Results and DiscussionThe proposed training program had a positive impact on the harmonic abilities and basic skills of basketball players and the differences in improvement rates for all variables were in favor of the experimental group. Therefore, the research suggests that Small-sided games using FITLIGHT positively affect all the variables under research. This leads to significant differences between the post-tests and benefits the experimental group.

The interest in the efficiency of online learning was and remains a major concern to researchers especially during the worldwide pandemic crisis (COVID-19). Nonetheless, there is a lack of studies focusing on students’ perceptions in online physical education (PE) learning sessions. Based on the self-determination theory (SDT), the present investigation aimed to explore psychological need satisfaction (PNS) to understand the autonomy, competence, and relatedness of Saudi PE students during the online sessions undertaken during the COVID-19 pandemic lockdown. PE students (N = 321, 161 females and 160 males) completed an online questionnaire composed of demographic characteristics, grade point average (GPA), sleep and physical activity (PA) habits, and the physical education autonomy relatedness competence scales (PE-ARCS). A t-test and one-way ANOVA were conducted and revealed that female students presented higher PNS compared with males. Students practicing PA had higher autonomy values than those not practicing PA (p = 0.001). However, no differences were recorded concerning competence and relatedness perceptions. The groups practicing walking, aerobic exercise, muscular training, and specialty training had higher values in autonomy and relatedness. The groups that slept for more than six hours a night, had previous experience with online learning, and had a GPA of more than three recorded higher PNS values. Correlation analysis showed high interdependence of the three PNS variables as well as with the variables of gender, experience with online learning, sleep hours, and type of PA practiced, but not with GPA or frequency of PA practice. The PNS values regarding online PE sessions were (i) higher in female students compared with males and (ii) related to previous experience in online learning, GPA, sleep habits, and type of PA. Walking, aerobic exercise, muscular training, and training in a specialty affected both autonomy and competence perception; however, relatedness was mainly affected by walking activity. Therefore, it is necessary to support ICT knowledge of students with low GPAs and to encourage them to adopt balanced sleep and physical activity habits to increase their perceptions of autonomy, competence, and relatedness in online PE lessons.

Background Eating less and moving more are the simplest and most common strategies to combat excessive weight. Several other lifestyle factors can also contribute to maintaining a healthy weight. Objectives The present study examined the effects of breakfast frequency, duration and quality of sleep, daily physical activity, sedentary behaviours, and school transportation on the BMI of Saudi students, aged 10–15 years. Materials and Methods This study included 981 students (240 girls (24.46%) [66 children (27.5%) and 174 adolescents (72.5%)] and 741 boys (75.54%) [441 children (59.51%) and 300 adolescents (40.49%)]). For each participant, height, weight, and body composition were obtained using bioelectric impedance analysis. A questionnaire focussing on lifestyle behaviours over the last seven days was also completed by each student. Multiple comparisons were performed to test for significant differences between the groups, stratified by sex, age, and BMI. Stepwise multiple regression analysis was used to determine the variables that significantly affected BMI. Results The overall prevalence of overweight and obesity in boys was 12.82% and 25.1%, and in girls, 10.42% and 5.42%, respectively. Most participants used cars or buses as transportation to and from school (100% of girls and 83% of boys). Breakfast was skipped mainly by male participants. Boys tended to sleep more than girls during school days (488.90 ± 74.33 vs. 467.76 ± 78.75 min. night −1 ). They were more active (2.58 ± 0.69 vs. 2.34 ± 0.82), used laptops more frequently (2.46 ± 1.51 vs. 1.90 ± 1.63), and played more video games (3.12 ± 1.43 vs. 1.2875 ± 1.36) than girls. However, girls were less sedentary (2.63 ± 0.76 vs. 2.9±.79), watched more TV (3.65 ± 1.155 vs. 2.73 ± 1.48) and used their smartphones more (3.6625 ± 1.3 vs. 3.28 ± 1.44) than boys. Conclusions This study revealed significant associations between BMI and breakfast intake, physical activities, and sedentary behaviours. Of these, using laptops and playing video games were the key sedentary activities that influenced BMI. Key messages A significantly higher prevalence of overweight and obesity was noted among boys compared to girls in private school students, aged 10–15 years, in Al-Ahsa governorate, Eastern Province of Saudi Arabia. Boys slept more than girls on school days, and they were more active, used laptops more frequently, and played more video games than girls. Girls were less sedentary, watched television more often, and used smartphones more frequently than boys. Among private school students aged 10–15 years in Al-Ahsa governorate, Eastern Province of Saudi Arabia, BMI was significantly associated with breakfast intake frequency, physical activity, and sedentary behaviours, among which using laptops and playing video gam...

Encouraging physical activity (PA) for adolescents is necessary to achieve and maintain optimal health, but it may increase the risk of PA-related injuries. This study sought to assess the frequency, location, type, and severity of PA-related injuries in Saudi students aged 13 to 18 years and to identify associated risk factors. A total of 402 students, including 206 boys aged 15.87 ± 1.69 years and 196 girls aged 15.83 ± 1.70 years, were randomly assigned to participate in this study. For each participant, height, weight, body mass index, and fat percentage were measured. Responses to a specially designed four-part self-administered questionnaire were also collected. Results revealed that better specific knowledge was associated with a lower likelihood of sustaining injuries (β = −0.136; p = 0.001) but increased sedentary behaviors were associated with a greater likelihood of sustaining a PA-related injury (β = 0.358; p = 0.023). Gender, knowledge, and sedentary behaviors were the factors overall associated with a greater likelihood of suffering 1, 2, and 3 or more PA-related injuries. However, gender, fat-free mass, knowledge, and sedentary behaviors were associated overall with a greater likelihood of bruises, strains, fractures, sprains, concussions, and at least two types of PA-related injuries. Collectively, we should pay attention to the PA-related injury problem among middle and high school students, particularly when promoting a physically active lifestyle.
