Review Articles Publication Policy
The Yalova University Journal of Sports Sciences (YUJSS) prioritizes the publication of high-quality original research articles. In line with this policy, review-type submissions are considered only under specific criteria and with limited frequency.
General Principles:
• The proportion of review articles published in each issue is limited to a maximum of 20%.
• Only systematic reviews, meta-analyses, and critical literature reviews with clear methodological structure and substantial academic contribution will be considered for evaluation.
• Narrative reviews that consist of simple literature summaries and offer limited scholarly contribution will not be considered for peer review (and may be rejected or returned to the author during the initial editorial screening by the Editorial Board).
• Review articles must be authored by scholars with recognized expertise in the field and must include a broad, up-to-date, and relevant literature base (preferably with at least 50% of references published within the last five years).
• When deemed necessary, review articles may only be accepted upon editorial invitation, particularly in thematic issues or when aiming to present expert perspectives on current topics.

8. While writing an article, in-text citations and references should be by the following rules;

1. Direct quotation
When directly quoting a source, in-text citations should always include the author, year, and page number, and if the direct quotation is less than 40 words, it should be enclosed in double quotation marks.

Example;
Bandura (1997) defines self-efficacy as "an individual's judgment about his or her capacity to organize and successfully perform the activities necessary for a given performance" (p.65).
If the direct quotation consists of 40 or more words, start the quotation on a new line by typing half an inch (1.25 cm) from the left side. If the quoted passage is to be followed by a second paragraph, the first line should start half an inch further in.
Example;
The description method is defined by Kaptan (1995) as follows: "These are studies that try to describe and explain what events, objects, entities, institutions, groups and various fields are. It aims to find an answer to the question, "What are these?". With this, existing situations, conditions, and characteristics are tried to be revealed exactly. Descriptive research aims to explain the interaction between situations, considering the relations of current events with previous events and conditions" (p. 59).
2. References to single-author works include the surname and date of the author.
Example Reference.
Öntürk, Y. (2019). Examining the relationship between mobbing behaviors towards academicians and quality of work life. Turkish Studies Social Sciences Volume:14(6), 3321-3340.
Citation (Öntürk, 2019).
Important Note: When citing two or more references, the author(s) should ensure integrity in using -ve, -& in the text and the imprint. For example, if it is written as (Öntürk and Yıldız, 2020) in the text, -ve should be used throughout the article (in-text and imprint). It is not appropriate to use -ve in one source and -& in another source.
3. For a study with two authors, the surnames of both authors should be included in each reference.
Example Reference.
Önturk, Y., & Yıldız, Y. (2020). Investigation of the motivational persistence levels of the students studying at the faculty of sports sciences according to some demographic characteristics. Asian Journal of Education and Training, 6(3), 514-519.
Submission (Öntürk & Yıldız, 2020).
4. When referring to studies with three, four, and five authors, the surnames of all authors are given only in the first reference in the text. For other references, the phrase and others should be added next to the first author's surname. In articles written in English, the expression et al. should be used instead of others when referring to publications with three, four, or five authors.
Example; First reference (Öntürk, Karacabey, & Özbar, 2019), Second and subsequent references (Öntürk et al., 2011).

6. If a group/legal entity (such as associations, companies, government agencies, and other working groups) is referred to as the author, the name of this group should be given in a very clear and understandable way in the reference in the text. In some cases, the name of the group can be abbreviated. In the first use, the full and abbreviated forms can be used, and in subsequent services, only the abbreviation can be used.
Example; If the reference is made at the end of the sentence; the First reference (Scientific and Technological Research Council of Turkey [TÜBİTAK], 2013)
Second and subsequent references; (TÜBİTAK, 2013). If the reference is made in a sentence, the First reference is the Scientific and Technological Research Council of Turkey (TÜBİTAK, 2013)
Second and subsequent references; TUBITAK (2013)
7. Multiple references within the same parenthesis; Multiple references within the same parenthesis should be in alphabetical order according to the surname of the first author and separated by semicolons.
Example; (Akçay & Doğan, 2013; Derman, 2003; Yıldırım, 2017)
8. If different studies by the same author are to be given in the same parenthesis, the year order from past to present is followed, and the author's surname is written once at the beginning of the reference.
Example; (Yıldırım, 2015, 2017)
9. Studies by the same author or a group of authors with the same name in the same year are separated by the letters a, b, c.
Example; (Yıldırım, 2015a, 2015b)
10. The References section should start on a new page. All references cited in the text should be included in the 'References' list. References should be given in alphabetical order in the References section. For Turkish and foreign references with more than one author, 'and' should be written before the last author's surname.
