It is important to develop motor skills starting from childhood and to participate in a variety of physical activities for this. In this study, it is aimed to reveal the motor development of 7-10 years old boys who receive multi-skill movement training outside of school and to examine the developmental differences. 61 volunteer college students participated in the study, the sample was divided into 31 students as a control group and 30 students as an intervention group receiving multi-skill movement training outside of school. The Test of Gross Motor Development-2 test, which includes locomotor and object control skill subtests, was applied to monitor the motor development of the children participating in the study. Gross motor skill scores from these two subtests were evaluated. At the end of the 12-week movement program, the study group showed a statistically significant improvement in gross motor skills, object control and locomotor sub-skills compared to the control group. A statistically significant improvement was found only in the object control sub-skill in the control group, whose in-school movement education continued. As a result, physical education activities at schools should be evaluated in terms of their duration and content, and children's participation in physical activities that show diversity should be evaluated in terms of motor development.

However, transfer of these improvements to different skills or functional activities is still unclear. The purpose of this study was to investigate the effects of mental balance training programs on motor coordination and skill transfer. Design: Randomized controlled trial. Methods: Fifty-seven healthy adults (28 females and 29 males) aged between 18 and 25 years participated in this study. Participants were randomly assigned to 3 groups: virtual reality (VR) mental training group, conventional mental training group, and control group. The training program included action observation and motor imagery practice with balance exercise videos. The VR mental training group trained with a VR head-mounted display and the conventional mental training group trained with a nonimmersive computer monitor for 30 minutes, 3 days per week, for 4 weeks. Coordination skills were tested with 2 separate custom-made obstacle course...

Yontem: Calismaya yaslari 10-18 arasinda degisen 10 spastik SP’li birey (3 kiz 7 erkek) dahil edildi ve 12 hafta boyunca video oyunu temelli aerobik egitim programina dahil edildiler. Egitim programi, kosma, merdiven inip cikma, ziplama gibi aktivitelerden ve interaktif bir video oyunundan olusmaktaydi. Aerobik gucu degerlendirmek icin Astrand Bisiklet Ergometresi Testi; dikkat ve yonetici islevleri degerlendirmek icin Simon Testi ve Isaretleme Testi egitim programi oncesinde ve sonrasinda uygulandi. Bulgular: Egitim programi sonucunda SP’li bireylerin aerobik guc duzeylerinde artis saptandi (Aerobik guc: egitim oncesi: 30,2±9,7 mL.kg -1 .dk -1 , egitim sonrasi: 32,3±9,8 mL.kg -1 .dk -1 ) (p 0,05). Sonuc: Bu sonuclar, video oyunu temelli aerobik egitim programi spastik SP’li bireylerin aerobik guc duzeylerini olumlu ...

The lack of evidence in static stretching studies led researchers to dynamic stretching protocols that simultaneously enhance basic skill level, kinaesthetic awareness, range of motion, and core temperature. However, it needed to be clarified in which part of the warming up the dynamic stretching phase should be done. This study investigated the acute effect of the dynamic stretching exercise phase before and after a warm-up on the 20m sprint performance. The study included forty-four soccer players, aged 16.59±1.06 years, who played for amateur teams. Participants were randomly divided into two groups on the first day of the study. In the first group, dynamic stretching was performed before warm-up (BGW), and the players' 20m sprint performances were tested. In the second group, dynamic stretching was performed after the warm-up (AGW), and the players' 20m sprint performances were tested. On the second day of the study, the same protocol was applied to the same players by changing groups of players. The average speed in the 20m sprint test of the BGW group (2.96±0,13 sec.) was found to be significantly shorter than the AGW group (3.01±0,12 sec., p<0.05). The difference in the 20 m speed test values between groups was significant (p<0.05). The findings obtained in the applied experimental condition show that the dynamic stretching protocol applied before the warm-up running phase increases the sprint running performance. It may be more beneficial for the performance of athletes to do dynamic stretching before sprint running performances.

Methods: This study is a cross-sectional-analytical, self-controlled intervention. The distance CST program was applied to first-year medical students. The change in students’ empathy levels was measured with the student version of the Jefferson Empathy Scale. Results: 241 students’ forms were included. Empathy mean score increased significantly, this increase was higher in women. Conclusion: The distance CST produced a positive effect on empathy levels. While interactive PowerPoint® presentations, videos, movie clips, cartoons, real-life examples, written/audio question- answer activities, surveys, feedback and, small group work were used in live lessons; in the asynchronous process, student-based techniques (self-assessment, homework, WhatsApp® sharing)...

This review examines the changes in cerebral blood flow and metabolism during head-out water immersion and in-water exercise Method: Systematic research was conducted in PubMed, ScienceDirect, Scopus databases, by binary research methods. It included 11 articles that met the inclusion criteria. Results: Studies have shown that acutely vertical head-out immersion in thermoneutral water and in-water exercise positively affects the circulation and metabolism of the brain. Conclusion: In healthy people, vertical immersion in thermoneutral water increases brain activity by increasing cerebral artery velocity and oxygenation. But acutely immersion in hot and cold water does not have a positive effect on cerebral circulation.
