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.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
