The present study examined the effects of an 8-week extracurricular outdoor physical activity program aimed to improve long-term memory performance in adolescent concerning the Covid-19 period. Participants were 40 schoolchildren (aged 16-17) who trained twice a week in aerobic exercise two hours per session, randomly assigned to participate in either an extracurricular outdoor physical activity program (EG;n = 20) or a waitlist control group (CG;n = 20). At baseline and after training we administered the Verbal Paired Associates (VPA-I) a subtest of the Wechsler Memory Scale - IV (WMS-IV, 2009), which represents one of the most widely used instruments for assessing explicit episodic memory performance. The results suggested that after 8-week aerobic exercise program students were able to increase their long-term memory, and that this capacity was more evident following physical activity that required greater cognitive involvement.
本研究调查了一项为期8周的课外户外体育活动计划的效果，该计划旨在改善青少年在Covid-19期间的长期记忆表现。参与者是40名小学生(16-17岁)，他们每周进行两次有氧运动，每次训练两小时，随机分配参加课外户外体育活动项目(EG, n = 20)或候补对照组(CG, n = 20)。在基线和训练后，我们进行了言语配对联想(vpa - 1)，这是韦氏记忆量表-IV (WMS-IV, 2009)的一个子测试，它代表了评估外显情景记忆表现最广泛使用的工具之一。结果表明，经过8周的有氧运动项目后，学生们能够提高他们的长期记忆力，而且这种能力在需要更多认知参与的体育活动后更为明显。

Background: The use of smart phones has become increasingly popular and almost indispensable in contemporary life, but many studies have addressed that excessive use negatively affects the various developmental domains. Purpose: The purpose of this study was to examine the effect of prolonged smartphone use on the forward neck translation, neck flexion angle and handgrip power for duration of 8 weeks. Materials and Methods: Ninety students from nine different international schools in Sharjah, UAE, with age ranging between 13-17 years. Participated in this study. Subjects were divided into two groups based on their daily frequency of smartphone use. Group (I) using smart phones less than 4 hours/day and Group (II) using more than 4 hours/day. The Neck flexion angle and forward neck translation were measured by the posture assessment mobile application (PostureCo, Inc), during their normal straight upright postural standing position. Handgrip power was measured with a Handheld Dynamometer (HHD) for both dominant and non-dominant hands, with arms abducted 30 degrees and wrist slightly extended (10 degrees). Measures were repeated 3 times and the average was considered for data analysis. Results: After 8 weeks of smart phone usage, statistical analyses revealed significant increase and decrease in the forward neck translation and neck flexion angles respectively. On the other hand, there were no statistically significant differences in handgrip power in both groups. Conclusion: Our results revealed the significant effect of the prolonged use of smartphones on the neck flexion angle, forward head translation without affecting handgrip power.
