This article is written in the form of a literature review for the journal Sportscience. A few of the requirements for form and content are unique to Sportscience, but most are common to all good scientific journals. You can therefore use this article to help you write a review for any journal. You can also use this article to structure a literature review for a thesis, but check with your supervisor for any special requirements.
When it comes to composing a literature review, the first desire is to go and look for an example, but in order to understand the specifics of creating such work, it is important to clarify the difference between this kind of academic writing and a research paper. The key purpose of every research paper is to present an original argument, while creating a review basically means generalizing and synthesizing thoughts and conclusions of other people without an aim to come up with any original arguments.
Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature, and theoretical articles.
Whether you are writing a review for Sportscience, another journal, or a thesis, you should read my guidelines on scientific writing (). Here are the main points from that article:
At this very time, do not neglect the importance of libraries as they have copies of rare academic journals and books, which are not available online. You may find there a database of textbooks, journal articles, newspaper articles, magazines features, reports, etc. But the most relevant sources for writing the literature review are the journal articles, and you will have to, first of all, observe the most recent publications related to your field of study.
This section is the most important part of your review. Do not give a summary paper-by-paper; instead, deal with themes and draw together results from several papers for each theme. I have identified four themes for this section: assessing the quality of published work; interpreting effects; points of grammar and style; and a few remarks about tables and figures. These themes are dealt with under subheadings. I encourage you to use such subheadings, which will make it easier for you to write the review and easier for others to read it.

In the statistical approach, effects or outcomes are expressed as statistics that are independent of the units of measurement of the original variables. These statistics are the same ones referred to in the previous subsection: relative risk, variance explained, and effect size. Statisticians have come up with rules of thumb for deciding whether the magnitude of the effect is to be considered trivial, small, moderate, or large. For example, claims that an effect size of 0.2, a variance explained of 1% (equivalent to a correlation coefficient of 0.1), and a relative risk of 1.2 are the smallest effects worth detecting. I have extended Cohen's scale to effects of any magnitude, and I have made adjustments to his scale ().
