Our journal Exercise and Sport Sciences Reviews (ESSR) publishes two types of review articles. In the most common type of article, authors are required to present a novel hypothesis that is derived from several of their peer-reviewed publications. Based on our understanding that a hypothesis represents an expected outcome derived from a model of the involved system, these articles are required to provide a rationale for why a particular outcome can be predicted based on the existing literature on the identified issue. Within this framework, subsequent outcomes, whether they are consistent with the hypothesis, will inform us about the intrinsic characteristics of the system. In an effort to reach a broad audience, including those who are not experts on the topic, authors are required to develop a succinct hypothesis, provide a declarative title that states the main point of the article, and include a list of three to five key points about the article. We previously limited the reference list to 35 citations so that the article remains focused on the novel hypothesis. Based on a discussion at the editorial board meeting in Boston, however, we have now decided to increase this limit to 50 citations.

In the other type of article, senior investigators who are still active in research are invited to provide a synthesis of the current state in a particular field, identify gaps in knowledge, and suggest key questions that need to be addressed. We refer to these articles as Perspectives for Progress. Former editor-in-chief Priscilla Clarkson originally proposed these types of articles as a mechanism to provide more comprehensive review articles in the Journal, but there have been too few of these articles in recent years. At the editorial board meeting in Boston, there was renewed interest in soliciting more of these types of articles and expanding the reference limit from 50 to 150 citations. Our goal for 2017 is to include three to four Perspectives for Progress articles throughout the year.

The Journal received positive feedback regarding the Journal Club questions, and we have now added another online-only feature, video abstracts. We invite one author from each issue to submit a 3-min video abstract to accompany their article. The video abstracts can be viewed at We also are strongly encouraging authors to supplement their written articles with digital content. Authors are encouraged to upload audio, video, or data/text files that enhance their article. For example, the supplemental digital content could include extra tables or figures that add to the content in the article, but are not essential to it. In addition, authors could upload videos to demonstrate a data-collection procedure or the performance of a task discussed in the article. Authors should refer to the ESSR Instructions for Authors or contact the editorial office for specific guidelines on these digital features.

With these initiatives, we expect to sustain the upward trajectory of our impact factor, which went from 4.259 in 2014 to 4.451 in 2015. Despite the acknowledged limitations of this metric, the impact factor does influence the willingness of some authors to contribute articles to our Journal, and we want to make an invited opportunity as enticing as possible.

On behalf of the Journal, I also thank the outgoing editorial board members who contributed to ESSR throughout their terms: Thomas J. Hawke, Kathy H. Myburgh, and Patricia A. Nixon. We also welcome to the editorial board the following individuals whose expertise in the ACSM categories varies in Athlete Care and Clinical Medicine; Biomechanics and Neural Control of Movement; Clinical Exercise Physiology; Immunology, Genetics, and Endocrinology; Metabolism and Nutrition; Skeletal Muscle, Bone, and Connective Tissue — Carol Garber, Charlotte Suetta, Susan V. Brooks, Inge Zijdewind, and Nancy I. Williams.
