Summary
The number of physical activity (PA) publications has surged, driven by open-access journals. This exponential growth may challenge research quality and accessibility.
Area of Science:
- Bibliometrics
- Scientific Publishing
- Public Health
Background:
- The volume of physical activity (PA) publications has significantly increased since 1985.
- This growth reflects a global trend, complicating evidence synthesis and strategy identification.
Purpose of the Study:
- To analyze trends in PA publications from 1985 to 2022.
- To identify factors driving the increase in PA research output.
Main Methods:
- A comprehensive review of the Scopus database for publications with "physical activity" in the title or keywords.
- Analysis of 193,335 PA publications between 1985 and 2022 using a standardized search strategy.
Main Results:
- Three distinct periods of publication increase were observed: 1985-2000, 2001-2016 (9-fold increase), and 2017-2022.
- The shift to open-access (OA) journals was the primary driver, accounting for 80% of publications by 2017-2022.
- OA publication growth varied globally, with some countries showing more pronounced increases.
Conclusions:
- The exponential rise in PA publications poses a threat to research quality and the practical application of findings.
- Open-access journals, with higher acceptance rates and faster publication times, are a key factor in this trend.
- This shift represents a
- commercial determinant
- influencing publication volume and type without guaranteed contribution to evidence or impact.

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
