Abstract Submission Instructions

General Information

A limited number of abstracts can be accommodated for the 2017 Congress. Abstracts will be reviewed by the Congress Program Committee, and authors will be notified of the Committee decision by the end of March. Accepted abstracts will be published online in International Journal of Sports Physiology and Performance. The first author agrees to provide a poster presentation during the Congress.

All questions regarding abstracts should be directed to Dr. Marty Hoffman at ([email protected]) or 916-843-9027 (USA).

 

Rules for Submission

  • Abstracts must be submitted electronically to Dr. Marty Hoffman ([email protected]). Submission deadline is March 1, 2017. Abstracts received after this date will not be reviewed. You will receive a confirmation email within a few days of submission that the abstract has been received.
  • The first author of accepted abstracts must be registered for the meeting and present the abstract at the meeting.
  • All authors must have approved the submitted abstract.
  • The primary focus and substance of the submitted abstract must be novel. The abstract must not have been published as an abstract or as a full paper in a scientific, medical or professional publication at the time of submission.
  • There is no fee for abstract submission.
  • Presenters who find that they will be unable to present an accepted abstract must provide notice of a reason acceptable to the Committee or will otherwise be prohibited from presenting at future meetings.
  • Abstracts must be submitted electronically using the instructions below.

 

Abstract Preparation

General Guidelines

  • Abstracts should be written in English, prepared using Times size 12 font, and submitted as a word document.
  • Abstract text should be limited to 300 words. If including a table, chart or figure, please adjust word count to accommodate the graphics.
  • Data should be presented in units of measurement of the Systeme International de’Unite (SI).
  • Brand names should not be used in the abstract.
  • Citations are not included in the abstract.
  • Research must be approved by an institutional review board, but such approval should not be stated in the abstract.

Abstract Format

  • Title: The title should be brief (limited to 15 words).
  • Authors: The first name, middle initial (if used), and last name of each author should be provided. Highest degree(s) should be included after the name. Separate names by a semicolon (;).
  • Institutions: Institutions of all authors should be listed. When all authors are not affiliated with each institution, use superscript numbers to identify affiliations.
  • Text: The text must include the categories OBJECTIVE, METHODS, RESULTS, and CONCLUSIONS.

Objective.—This work combines and reanalyzes five years of exercise-associated hyponatremia (EAH) research at 161-km ultramarathons in northern California with primary purposes to define the relationship between post-race blood sodium concentration ([Na+]) and change in body weight, examine the interactions among EAH incidence, ambient temperature and hydration state, and explore the effect of hydration status on performance.

Methods.—Pre-race and post-race body weight and finish time data were obtained on 887 finishers, and post-race [Na+] was also obtained on a subset of 669 finishers.

Results.—EAH incidence was 15.1% overall (range 4.6-51.0% by year) and had a significant positive relationship with ambient temperature. Of the runners with EAH, 23.8% were classified as overhydrated (weight change ≥0), 40.6% were euhydrated (weight change <0 to -3%), and 35.6% were dehydrated (weight change <-3%) at the finish. There was a weak significant relationship (r=0.17, p<0.0001) between post-race [Na+] and change in body weight such that a lower [Na+] was more common with increased weight loss. Considering all finishers examined, 18.5% were dehydrated and 34.9% were overhydrated at the finish. There was a weak significant relationship (r=0.092, p=0.006) between change in body weight and performance in that faster runners tended to lose more weight. Top finishers varied in body weight change from ~1% gain to ~6% loss.

Conclusions.—EAH incidence can be high in 161-km ultramarathons in northern California. In this environment, EAH is more common with dehydration than overhydration and is more common in hotter ambient temperature conditions. Because weight loss >3% does not appear to have an adverse effect on performance, excessive sodium supplementation and aggressive fluid ingestion beyond the dictates of thirst are ill-advised.
