Module 1E Systematic Literature Search Strategies

Search Strategies for Evidence-Based Training Decisions

  • Two main search strategies:
    • Systematic.
    • Unstructured.
  • The choice depends on the type of review article or decision-making process.

Narrative Reviews

  • No formal search strategy.
  • Articles are selected to support the argument.

Systematic Reviews and Meta-Analyses

  • Require a systematic process.
  • Use specific search terms and operators.
  • Aims to retrieve relevant literature for review.

Focus: Systematic Literature Search

  • Relevant for the major assignment (literature review).
Steps in a Systematic Literature Search
  1. Identify Keywords: Determine keywords from the research question/topic.
    • Example: "effect of velocity-based training on sprint performance."
    • Keywords: "velocity based training", "sprint performance".
  2. Search Databases: Use databases such as PubMed, Scopus, SportsDiscus, Google Scholar.
    • Available through the ECU library.
  3. Retrieve Literature: Find articles related to the search terms.
Keyword Considerations
  • Avoid overly broad terms: Results in too much irrelevant information.
  • Avoid overly narrow terms: Results in too little information.
  • Use Boolean operators to refine the search.
Boolean Operators
  • Modify searches to be more precise or broad.
  • Three main operators:
    • AND.
    • OR.
    • NOT.
AND Operator
  • Retrieves articles containing both search terms.
  • Narrows the search.
  • Example:
    • Instead of "sprint speed" and "power output" separately, use "speed AND power".
    • "resistance training AND oncology" for effects of resistance training on oncology outcomes.
    • "hamstring strength AND sprinting performance" or "injuries during sprinting" for injury prevention.
OR Operator
  • Connects synonyms.
  • Expands the search.
  • Retrieves articles containing either of the search terms.
NOT Operator
  • Retrieves articles containing the first term but not the second term.
  • Filters out results.
  • Should be used carefully as it can severely restrict results and lead to missing relevant information.
  • Example:
    • Searching for "speed NOT power" would exclude articles about power.
