Reducing Aggression and Improving Physical Fitness in Adolescents Through an After-School Volleyball Program.

ABSTRACT: This study aimed to determine the effects of an after-school volleyball program on aggression and physical fitness in 14-16 years old students. One hundred and seven participants were randomized to a small-sided volleyball (SSV) training group or a control group (CON). The SSV group completed 8 months of small-sided volleyball training twice a week after school in addition to the regular physical education classes. Yo-Yo Intermittent Recovery Level 1 test (YYIRT1), medicine ball throw (MED), vertical jump (VJ), and Buss and Perry's aggression questionnaire were evaluated before and after 8 months of training. Results revealed a significant interaction effect (group × time) in total sample for physical aggression [F(1, 105) = 17.688; p < 0.001], verbal aggression [F(1, 105) = 4.973; p = 0.028], anger [F(1, 105) = 7.662; p = 0.007], medicine ball throw [F(1, 105) = 36.143; p < 0.001], and YYIRT1 [F(1, 105) = 12.508; p = 0.001]. After-school small-sided volleyball for adolescents was accompanied by a significant decrease in aggression compared to physical education classes only. Additionally, adolescents from SSV group showed better results in physical fitness compared to the control group. Our findings significantly contribute to the understanding of possible mechanisms for reducing adolescents' aggression, which include enjoyment, motivation, and self-control through sport intervention.

Project description:Reach out and Read program (ROR) prepares young children to succeed in school by partnering with physicians and training them in handing out age appropriate books and to counsel parents about the importance of reading aloud to their children. Children served by ROR enter kindergarten with stronger vocabulary and language skills. The aim of this project was to improve the rate of distribution of books and physician advice about reading, to the families at each well child visit in the age range of six months to five years. This Quality Improvement (QI) project was conducted in a large inner-city pediatric residency clinic serving a lower socio-economic status under-served population. After reviewing the data from the past two years, we noticed that there was a tremendous drop in the percentage of books handed out at well visits and advice given to parents about benefits of reading aloud and self-reporting of parents reading to their child for four or more days in a week. Two goals were established: 1. To increase the rate of distributing books at every well child visit (WCV) from six months to five years of age by at least 80%. 2. To improve the rate of counseling given by the resident physicians to the families by at least 75%. A workflow was created to efficiently distribute books at well visits. A presentation about the ROR program was attended by all the physicians and residents. Reading tips in each exam room were posted to serve as a reminder for all providers and for the parents. A three question survey was collected from the families at the end of their well visit. A total of 210 surveys were collected from parents over a six month period. The percentage of handing out books at all well child visits increased from 30% to 96%. The rate of providers giving advice about the benefits of reading increased from 26% to 87%. The percentage of parents reading to their child greater than four days per week increased from 56% to 80%. Reading aloud is widely recognized as the single most important activity leading to literacy acquisition. With the above interventions, families participating in the ROR model at our clinic were more likely to read to their children, more likely to report reading aloud at bedtime, and to read aloud four or more days per week.

Project description:BackgroundAdolescents with overweight and poor physical fitness have an increased likelihood of developing cardiovascular diseases during adulthood. In Ecuador, a health promotion program improved the muscular strength and speed-agility, and reduced the decline of the moderate-to-vigorous physical activity of adolescents after 28 months. We performed a sub-group analysis to assess the differential effect of this intervention in overweight and low-fit adolescents.MethodsWe performed a cluster-randomized pair matched trial in schools located in Cuenca-Ecuador. In total 20 schools (clusters) were pair matched, and 1440 adolescents of grade 8 and 9 (mean age of 12.3 and 13.3 years respectively) participated in the trial. For the purposes of the subgroup analysis, the adolescents were classified into groups according to their weight status (body mass index) and aerobic capacity (scores in the 20 m shuttle run and FITNESSGRAM standards) at baseline. Primary outcomes included physical fitness (vertical jump, speed shuttle run) and physical activity (proportion of students achieving over 60 min of moderate-to-vigorous physical activity/day). For these primary outcomes, we stratified analysis by weight (underweight, normal BMI and overweight/obese) and fitness (fit and low fitness) groups. Mixed linear regression models were used to assess the intervention effect.ResultsThe prevalence of overweight/obesity, underweight and poor physical fitness was 20.3 %, 5.8 % and 84.8 % respectively. A higher intervention effect was observed for speed shuttle run in overweight (β = -1.85 s, P = 0.04) adolescents compared to underweight (β = -1.66 s, P = 0.5) or normal weight (β = -0.35 s, P = 0.6) peers. The intervention effect on vertical jump was higher in adolescents with poor physical fitness (β = 3.71 cm, P = 0.005) compared to their fit peers (β = 1.28 cm, P = 0.4). The proportion of students achieving over 60 min of moderate-to-vigorous physical activity/day was not significantly different according to weight or fitness status.ConclusionComprehensive school-based interventions that aim to improve diet and physical activity could improve speed and strength aspects of physical fitness in low-fit and overweight/obese adolescents.Trial registrationClinicaltrials.gov identifier NCT01004367 .

Project description:(1) Purpose: The purpose of this study was to evaluate if an after-school intervention program could prevent obesity and promote the physical fitness of urban sedentary school children. (2) Methods: A 16-week after-school physical fitness program was provided to 36 middle school students (7th, 8th, and 9th graders) recruited from a middle school for three days a week. They were high-risk youth showing poor health status (level 4 or 5) in the regular physical fitness evaluation conducted. Their body mass index (BMI), cardiovascular endurance, muscular strength and endurance, quickness, and flexibility were evaluated. (3) Results: A paired sample t-test was used (α = 0.05). There were statistical differences ((x ± s), p < 0.05) between the pre-Progressive Aerobic Cardiovascular Endurance Run (PACER) (13.36 ± 4.98 (# of laps)) and post-PACER (18.64 ± 6.31 (# of laps)) (p < 0.001), between the pre-sit-up (18.06 ± 7.22 (# of sit-ups)) and post-sit-up (24.89 ± 7.52 (# of sit-ups)) (p < 0.001), and between the pre-Trunk Flexion (2.64 ± 3.49 ((cm))) and post-Trunk Flexion (5.97 ± 2.78 ((cm)) (p < 0.001). There was no statistical difference between the pre-50m-Run (10.74 ± 1.30 ((sec))) and post-50m-Run results (10.69 ± 1.25 (sec)) (p = 0.063) or between the pre-BMI (24.84 ± 3.97 (kg/m2)) and post-BMI (24.76 ± 3.61 (kg/m2)) (p = 0.458). Overall, the physical fitness measures improved, whereas BMI did not change after 16 weeks. (4) Conclusion: Sixteen weeks of the school-based Health-related Physical Fitness (HrPF) program can be effective in improving overall physical fitness levels of adolescents, although additional treatments would be required to change BMI, which showed no improvement in the present study. It is concluded that in order for adolescents to maintain and promote physical fitness and health, participation in a school-based HrPF program is recommended for at least 30 min a day, three days a week. In addition, schools should provide high-risk youth with easy access to physical activities that are similar to the objectives of the physical education curriculum. In order to promote the health of school-age children, each school should establish and operate school-based systematic intervention programs.
