El objetivo del estudio fue determinar el efecto de un programa de aprendizaje de las capacidades coordinativas sobre el tiempo en la prueba de patinaje de 300 metros contra reloj individual y la coordinación general. Participaron 14 niños y niñas entre los seis y ocho años de edad que fueron asignados aleatoriamente al grupo experimental (n=7) o grupo control (n=7); la media de la edad del grupo experimental fue 8,1 años (DE=0.5) y la media del grupo control 7,6 años (DE=0.82); con una experiencia deportiva igual para ambos grupos (16 meses). El grupo experimental tuvo un entrenamiento adicional de coordinación antes de la sesión cotidiana durante 20 sesiones distibuidas en siete semanas. El programa constó de 15 ejercicios en escalerilla realizados en cada sesión asi: tres ejercicios con dos series de 10 repeticiones y recuperación de 30 segundos en la primera serie y dos minutos después de la segunda. El grupo control no recibió estímulo adicional y continuó con el entrenamiento cotidiano del patinaje. Se realizó pre y post-test donde se midió la velocidad con la prueba de 300 m contra reloj individual en patines y la coordinación de los niños con el test Korperkoordination Test fur Kinder. Los resultados mostraron que existen diferencias significativas en las comparaciones intra-grupo, sin embargo, al realizar la comparación inter-grupos, se constató que no existen diferencias significativas (p= 0.180) en velocidad, pero en la práctica del patinaje estas diferencias son relevantes porque determinan una disminución en el tiempo de una prueba contra reloj, que puede significar un cambió ecológico significativo.Abstract. The research objective was to determine the effect of a learning program for coordination skills on the time of the 300-meter rollerblading test against individual clock and on general coordination. A sample of 14 boys and girls between six and eight years old, who were randomly assigned to experimental group (n=7) or control group (n=7) participated in the study; average age of the experimental group was 8,1 years old (SD=0,5), whereas in the control group it was 7,6 years old (SD=0.82); participants from both groups had similar sports experience (16 months). During 20 sessions over seven weeks, the experimental group received additional coordination training before each daily session. The program consisted of 15 ladder exercises, where in each session three exercises were performed with two sets of 10 repetitions and recovery of 30 seconds in the first series and two minutes after the second. The control group did not receive additional stimulus and continued with daily rollerblading training. Pre- and post-test were performed, with speed being measured during the 300m test against individual clock, whilst children's coordination was assessed with the Korperkoordination Test fur Kinder Test. The results showed significant differences in intra-group comparisons; however, when performing the inter-group comparison, no significant differences (p = 0.180) were found in speed. Nonetheless, in rollerblading practice these differences are relevant, because they determine a decrease in the time of a test against the clock, which may mean a significant ecological change.

          Peer teaching is a strategy that allows the students to teach the new content to each other, and they must be accurately guided by instructors.     The researcher proposes that the use of students peer teaching  may promote students' achievement  and ensure the engagement of all the students in the learning process. Therefore, the researcher employs it as a teaching method aiming at investigating its  effect on Iraqi EFL students' achievement in the course of Library and Research Work .      The study hypothesizes that there is no significant difference between the students' achievement who are taught library and research work by students peer teaching  and that of the students taught by the traditional way. The experimental design of the study is Parallel Groups, Random Assignment, posttest. Each group consists of 35 students, chosen randomly from the Third Year Students at the Department of English in the College of Basic Education. Both groups were matched in terms of their age and parents' education. The experiment was fulfilled in the first course for 15 weeks during the academic year 2016-2017.       The same materials were presented to both groups. This included   units from Writing Research Paper by Lester D. . Post-test was constructed and exposed  The t-test for  independent samples was used to analyze the results and it is found out that there is a statistical difference between the two groups in their achievement because the calculated t- value 2.635 is bigger than the tabulated t- value which is 2.000, and also shown the superiority of the experimental group. The results indicate that the experimental group, who was taught Library and Research Work by peer teaching   was better than the control group, who was taught according to the traditional way. So, the null hypothesis is rejected. Finally, some recommendations and suggestions are presented in the light of the study findings. to a jury of experts to verify its validity and it was administered to both groups.

Abstract Objective: To evaluate the use of biofeedback intervention in the levels of depression. The main hypothesis tested if the use of biofeedback improves depression levels compared to the control group. Methods: A randomised clinical trial. The final sample was composed of 36 participants (18 in the experimental group, receiving 6 training, once a week, with biofeedback; and 18 in the control group, who received conventional treatment in the service).Outcome measures were assessed in two stages: pre-test and post-test. The research used the following instruments: demographic survey data, Mini International Neuropsychiatric Interview 5.0.0 and Beck Depression Inventory (BDI). The factors and variables were presented in terms of descriptive and inferential statistics. Fisher’s exact test (p < 0.05) was used to verify the existence of an association between the counting variables. The multinomial logistic regression model was adopted, and the Logit link function was used, as the software RStudio version 3.6.2. Results: The factors that remained in the final model were group, sex, partner, atypical antidepressant, benzodiazepines, mood stabiliser, antiepileptic and antihistamine, according to the levels of depression based on the BDI. The group that did not receive biofeedback intervention had 16 times more chances of increasing the depression levels compared to participants in the experimental group. Conclusion: The use of biofeedback reduces depression, thus, representing a complementary alternative for the treatment of moderate and severe depression, and dysthymia.

Multidirectional running has been described as an important factor in team sports performance. The aim of the present study was to determine changes in T-test, 505 time, 10 m sprint, squat jump (SJ), countermovement jump (CMJ), countermovement jump right leg (CMJRL), and countermovement jump left leg (CMJLL) following exposure to 12 sessions over 4 weeks of a multidirectional running sprint training intervention in male and female handball players. A total of 31 handball players (15 male and 16 female) were recruited for this study and then randomly assigned to an experimental group (EG) or control group (CG). Male EG players showed improvements in 505 Preferred Side (PS) (p ≤ 0.05), 505 Non-Preferred Side (NPS) (p ≤ 0.05), and 10 m sprint (p ≤ 0.05), while female EG players presented statistically significant improvements between pre- and post-test for the T-test (p ≤ 0.05), 505 PS (p ≤ 0.05), 505 NPS (p ≤ 0.05), and 10 m sprint (p ≤ 0.05). No statistically significant pre- and post-test differences were observed in CG (all p ≥ 0.05) or between male and female players. We found an improvement in handball players’ agility and speed of movement following the intervention protocol, suggesting the need to introduce this program into our training sessions. It may also be necessary to select and develop more specific tests in order to evaluate multidirectional work in handball players.
