Exercise Science

This research guide will provide you with starting points for finding information on exercise science.

Evidence Pyramid

Image of evidence pyramid

There are many different versions of the evidence pyramid but the main thing it does is demonstrates the evolution of the literature. An idea conceived in a lab turns into therapies and diagnostic tools tested with laboratory models, then in animals and finally in humans. The human testing begins with volunteers and goes through several phases of clinical trials before the therapy or tool can be authorised for use within the general population.

Randomised controlled trials are done next to further test the effectiveness and efficacy of a drug or therapy.

The amount of literature decreases as you move up the pyramid but increases in its relevance to the clinical setting. As you move up the pyramid, the study design is more rigorous and allows for less bias or systematic error.

Subject Specific Filtered Resources

Filtered resources appraise the quality of studies and may make recommendations for practice.

Evidence-Based Answers to Clinical Questions for Busy Clinicians

Harris C & Turner T. Evidence-Based Answers to Clinical Questions for Busy Clinicians. (2011) The Centre for Clinical Effectiveness, Monash Health, Melbourne, Australia.

This is an excellent resource which takes you clearly through the process of developing your question, doing your search and appraising the evidence identified.

Some definitions

Evidence Based Practice (EBP) describes the practice of making decisions about patients and treatments based upon up to date and reliable evidence. For healthcare practitioners, this consists of "producing evidence; making evidence available; [and] using evidence" (Gray 2001, p14).

The following definitions come from the Centre for Evidence Based Medicine.

  • Systematic Review: an article in which the authors have systematically searched for, appraised, and summarised all of the medical literature for a specific topic.
  • Critically appraised topic: a short summary of an article from the literature, created to answer a specific clinical question.
  • Randomised controlled clinical trial: a group of patients is randomised into an experimental group and a control group. These groups are followed up for the variables/outcomes of interest.
  • Cohort study: involves the identification of two groups (cohorts) of patients, one which did receive the exposure of interest, and one which did not, and following these cohorts forward for the outcome of interest.
  • Case-control study: involves identifying patients who have the outcome of interest (cases) and control patients without the same outcome, and looking to see if they had the exposure of interest.
  • Meta-analysis: a systematic review which uses quantitative methods to summarise the results

General Filtered Resources

Filtered resources appraise the quality of studies and may make recommendations for practice.

Unfiltered Resources

Unfiltered resources are studies that have not yet been subject to critical appraisal via a process such as systematic review.  Some of these include randomised control trials, clinical trials, cohort studies, case-control studies.
