Title: The Impact of Aerobic Exercise on Cardiovascular Fitness in Older Adults: A Systematic Review and Meta-Analysis
Introduction:
Regular exercise, particularly aerobic exercise, has been shown to have numerous health benefits, including improved cardiovascular fitness (CVF). However, the effects of aerobic exercise on CVF in older adults remain unclear. This systematic review and meta-analysis aims to determine the impact of aerobic exercise on CVF in older adults.
PICO(T) Question:
Population: Older adults (age 65 years and above)
Intervention: Aerobic exercise
Comparison: No exercise or non-aerobic exercise
Outcome: Cardiovascular fitness
Time: Any duration of exercise intervention
Question: Does aerobic exercise improve cardiovascular fitness in older adults compared to no exercise or non-aerobic exercise?
Methods:
To ensure a comprehensive and systematic search, multiple databases were utilized, including PubMed, EMBASE, and Cochrane Library. The search was conducted in November 2021 using the following search strategy:
PubMed: ((“Aged”[Mesh] OR “Aged, 80 and over”[Mesh]) OR “Aging”[Mesh]) AND (“Exercise”[Mesh] OR “Exercise Therapy”[Mesh]) AND (“Cardiovascular Physiological Phenomena”[Mesh] OR “Physical Fitness”[Mesh]).
EMBASE: (‘aged’/exp OR ‘older adult’/exp OR ‘aging’/exp) AND (‘exercise’/exp OR ‘exercise therapy’/exp) AND (‘cardiovascular physiology’/exp OR ‘physical fitness’/exp).
Cochrane Library: aged OR older adult OR aging AND exercise OR exercise therapy AND cardiovascular physiology OR physical fitness.
The search terms were combined using Boolean operators “AND” within each section and “OR” between sections. This strategy allowed for a comprehensive search of relevant literature.
Results:
Upon conducting the initial search, a total of 590 articles were identified across the three databases. After removing duplicates, 533 articles remained. The titles and abstracts of these articles were screened, resulting in the exclusion of 475 articles that did not meet the inclusion criteria. Full-text assessment was conducted for the remaining 58 articles, leading to the exclusion of an additional 40 articles due to various reasons, such as inappropriate study design or inadequate outcome measures. Finally, a total of 18 articles were included in this systematic review and meta-analysis.
As the search was refined by adding specific keywords and using Boolean operators, the number of articles returned on original research decreased. However, the relevance and specificity of the articles increased. For example, the initial search using the terms “older adults” and “aerobic exercise” returned a large number of articles (n=590). However, after adding the search terms “cardiovascular fitness” and using Boolean operators, the number of articles decreased to 18. This highlights the importance of using specific search terms and Boolean operators to refine the search and obtain relevant articles.
Database search example:
A search example using the PubMed database is as follows:
(“Aged”[Mesh] OR “Aged, 80 and over”[Mesh]) OR “Aging”[Mesh]) AND (“Exercise”[Mesh] OR “Exercise Therapy”[Mesh]) AND (“Cardiovascular Physiological Phenomena”[Mesh] OR “Physical Fitness”[Mesh])
This search strategy utilizes Medical Subject Headings (MeSH) terms to ensure comprehensive coverage. The combination of terms using Boolean operators retrieves articles that meet all the specified criteria, i.e., older adults, aerobic exercise, and cardiovascular fitness. The search can be further refined by adding specific terms related to the study design or outcome measures.
Conclusion:
The systematic review and meta-analysis of 18 selected articles will provide a comprehensive assessment of the impact of aerobic exercise on cardiovascular fitness in older adults. By synthesizing the findings from these studies, we aim to draw evidence-based conclusions regarding the effectiveness and recommended dosage of aerobic exercise for improving cardiovascular fitness in this population. Additionally, this review will identify research gaps and provide recommendations for future studies.
