Abstract

Purpose: to compare the effects of plank strength levels over a 5-year period (2018 vs. 2023) considering the impact of the COVID-19 pandemic in children and adolescents.  Methods: This is a retrospective longitudinal case study that employed a quantitative approach, developed with schoolchildren from a school located in the South Brazil. The initial sample consisted of 221 students (58.8% boys) aged 6 to 11 years evaluated in 2018 (baseline). The same group of students was reevaluated in 2023 (follow-up) when they were aged 11 to 16 years. The assessment of isometric strength in the plank test was conducted by adapting the "core" strength test. The test was performed twice within the same session, and the best measurement was recorded. Additionally, a retest was conducted 7 days later. The abdominal resistance strength was evaluated through the sit-up test, according to the protocol of Projeto Esporte Brasil.  Results: Regarding the results of the pre-pandemic (baseline) compared to the post-pandemic (follow-up) in girls, a significant negative effect over the 5-year period was observed in the comparison of raw values for isometric strength in the Plank Test's first three measurements at baseline, compared to the follow-up. Similar 5-year negative effects were observed in boys as those seen in girls, both in the raw values, and in the age-adjusted values, where no significant differences were found.  Conclusion: isometric strength levels on the Plank test remained stable over the 5-year period, despite the impact of the COVID-19 pandemic, demonstrating consistent core strength in schoolchildren.
对儿童和青少年等距平板测试力量的 5 年纵向跟踪:COVID-19 前后的社会距离研究
目的:考虑到 COVID-19 大流行对儿童和青少年的影响,比较 5 年内(2018 年与 2023 年)平板力量水平的影响。 方法:这是一项回顾性纵向研究:这是一项回顾性纵向案例研究,采用定量方法,以巴西南部一所学校的学生为研究对象。初始样本包括 221 名学生(58.8% 为男生),年龄在 6-11 岁之间,评估时间为 2018 年(基线)。2023 年(随访)对同一批学生进行了重新评估,当时他们的年龄为 11 至 16 岁。通过改编 "核心 "力量测试,对平板测试中的等长力量进行了评估。测试在同一时段进行两次,并记录最佳测量值。此外,7 天后还进行了一次复测。根据巴西运动项目的方案,通过仰卧起坐测试评估了腹部阻力强度。 结果女孩大流行前(基线)与大流行后(随访)的结果对比显示,在平板支撑测试的前三次测量中,基线与随访的等长力量原始值对比显示,5 年间出现了显著的负效应。无论是原始值还是年龄调整值,在男孩身上观察到的 5 年负面影响与在女孩身上观察到的类似,没有发现显著差异。 结论:尽管受到 COVID-19 大流行病的影响,但平板测试的等长力量水平在 5 年期间保持稳定,这表明学龄儿童的核心力量始终如一。

期刊介绍: Sport Sciences for Health is an international, interdisciplinary journal devoted to researchers and practitioners involved in sport and physical activity for health. The journal deals with the mechanisms through which exercise can prevent or treat chronic degenerative disease contributing to prevention and personalized treatment of specific diseases and health maintenance with a translational perspective. It publishes original research, case studies and reviews. Areas of interest include sport, physical activities, sports medicine, healthy lifestyles, motor behavior, physical education and adapted physical activity with different methodological approaches such as physiological, clinical, biomechanical, performance, psychological, educational, social and learning perspectives. Sport Sciences for Health is the official journal of the Società Italiana delle Scienze Motorie e Sportive (SISMeS), an Italian scientific society that aims to promote, support and disseminate knowledge and innovations in the sciences of sport and physical activity for health and quality of life.
