Identifying Research Types
Experimental Research
Explanation: Experimental research involves manipulating one variable to
determine if it causes a change in another variable. This type of research often
tries to determine cause-and-effect relationships between variables. It is
characterized by the use of control and experimental groups and the application
of random assignment.
Look for: A clear statement of an intervention or treatment applied by the
researchers to one group while a control group does not receive it. There will be
pre-defined criteria for selecting participants, random assignment to groups, and
a specific outcome or set of outcomes measured.
Keywords: Randomized, control group, intervention, treatment, placebo.
Example Tip: Check if the study mentions a comparison between a group
receiving an exercise regimen (treatment group) and a group not receiving it
(control group) to observe the effects on a specific outcome like muscle strength
or endurance.
Example Study Title: "The Effects of High-Intensity Interval Training on
Cardiovascular Health in Sedentary Adults."
Qualitative Research
Explanation: Qualitative research focuses on exploring ideas, understanding
phenomena, and answering questions about concepts, meanings, and
experiences. It often involves collecting non-numerical data, such as interviews,
observations, and text analysis, to gain insights into people's behaviors,
motivations, and attitudes.
Look for: Descriptions of how people experience, perceive, or interpret an aspect
of exercise or physical activity. This research often involves interviews, focus
groups, or content analysis of text.
Keywords: Themes, perceptions, experiences, interviews, focus groups.

Example Tip: Look for studies that explore athletes' personal experiences with a
particular training program or their perceptions of recovery methods through
interviews or narrative analysis.
Example Study Title: "Exploring the Motivations Behind Marathon Running Among
Amateur Runners."
Mixed Methods Research
Explanation: Mixed methods research combines both qualitative and quantitative
research approaches to gain a comprehensive understanding of a research
problem. It involves collecting, analyzing, and integrating both kinds of data in a
single study or series of studies. This approach provides a more complete
understanding of research problems than either method alone.
Look for: The combination of both quantitative (e.g., numerical data analysis) and
qualitative (e.g., interviews) methods in the study design. This approach aims to
provide a more comprehensive understanding by integrating different types of
data.
Keywords: Integrative, combined methods, qualitative and quantitative, mixed
analysis.
Example Tip: Identify studies that might start with a survey to gather statistical
data on physical activity levels among different populations and follow up with
interviews to dive deeper into individuals' motivations and barriers.
Example Study Title: "A Mixed Methods Study on the Impact of School Physical
Education Programs on Adolescent Physical Activity Levels."
Epidemiological Research
Explanation: Epidemiological research studies the distribution and determinants
of health-related states or events in specified populations. It applies this study to
control health problems. This type of research can include observational studies,
such as cohort, case-control, and cross-sectional studies, to identify patterns,
causes, and effects in health and disease.
Look for: Large-scale population studies that investigate the distribution and
determinants of health-related states or events (including diseases) in specific
populations, and the application of this study to control health problems.

Keywords: Prevalence, incidence, cohort, cross-sectional, case-control.
Example Tip: Search for studies examining the relationship between regular
physical activity and the incidence of chronic diseases like diabetes or heart
disease across different populations or cohorts over time.
Example Study Title: "The Prevalence and Risk Factors of Overuse Injuries in
Collegiate Athletes: A Cross-sectional Study."
Meta-analysis
Explanation: A meta-analysis is a statistical technique that combines the results
of multiple scientific studies. It is used to identify patterns, draw conclusions, or
determine the effectiveness of interventions across numerous studies. Metaanalyses are valuable in evidence-based practices because they provide a high
level of evidence by synthesizing existing research.
Look for: A study that statistically combines the results of multiple studies on the
same topic to derive conclusions about the body of research. The text will discuss
the criteria for selecting studies, the statistical methods used to combine their
results, and an overall assessment of the evidence.
Keywords: Systematic review, pooled analysis, effect size, heterogeneity.
Example Tip: Look for articles that review and synthesize outcomes from several
studies to determine the overall effectiveness of specific exercise interventions on
weight loss or improving cardiovascular health.
Example Study Title: "Meta-Analysis of the Effectiveness of Resistance Training
Interventions in Improving Muscle Strength in Older Adults."
