References 

References and sources must adhere to the "American Psychological Association" (APA, seventh edition) format.
Only references cited in the text should be included. Every citation must have its corresponding reference.
Manuscripts that do not meet the above requirements will not be evaluated until they comply.
Bibliographic citations in the text of the article should follow this procedure:
If there is just one author, the surname goes first followed by the year of publication in parentheses, e.g.: “hypoxia diminishes maximal cardiac output” (Pugh, 1964).
If the manuscript is written by two authors, their names will appear before the year of publication, e.g.: “Elastic potentiation contributes to an improved jump capacity” (Komi and Bosco, 1972). If there are more than two authors, the first time must be all of them and the next time the first author’s surname and “et al.,” are used followed by the year of publication, e.g.: “Lower leg moment of inertia increases with growth” (Fernández et al., 1975).

If more than two papers are cited, they should be separated by “;” in alphabetical order, e.g.: “Transverse section of muscles is the main factor determining muscle strength” (Arteaga and Ramírez, 1999; Comí, 1992; Kraemer et al., 2000). If papers of the same group or author published in the same year are cited, they will appear in chronological order with the letters “a, b, c, d, …” followed by the date. e.g.: (Kraemer et al., 1996a; 1997a,b).

In the section of references, citations will appear in alphabetical order. Citations should include the surname of the authors followed by the initials of the name. If the paper is written by more than one author, authors will be cited consecutively up to a maximum of seven, separated by commas. If there are more than seven authors, the first three are listed followed by “et al.,”. The year of publication will be cited in parentheses following authors, then, the title of the paper, the journal abbreviation (italics) in accordance with the abbreviations of Science Citation Index and Social Science Citation Index. If the journal does not appear in the indexes abovementioned, the full name of the journal should be cited. Finally, the volume number in italics and the number of the first and last pages separated by a hyphen.

Tables

Tables must follow the latest APA edition format and be numbered in the text according to the order in which they are mentioned, e.g., (Table 1). Tables should be self-explanatory. If abbreviations are used in the tables, they must be explained in the table footnote. The format of the tables should be as simple as possible, reducing the number of lines to separate columns or rows to a minimum. The maximum number of tables is 5 for literature reviews and original works.

Figures
Figures must be cited in the latest APA edition format and numbered consecutively in the text, abbreviated and in parentheses, e.g., (Fig. 1). The number of figures should be limited to a maximum of 7 for original works and literature reviews. Only include figures in the work if they facilitate the understanding of the results obtained.
