Background: Since the invention of Gatorade, the sports nutrition market has expanded rapidly. While the market has expanded, a way to catalogue these sports nutrition supplements (SNSs) has not followed. This lack of centralized information creates a problem for dietitians and other health professionals who need to make informed recommendations for their clients using SNSs. Objective: The objective of this project is to assess the need for a SNS formulary and develop a formulary based on need. Method: The need for the formulary was assessed by creating and distributing a survey to dietitians and other health professionals who subscribe to the Nutrition Care Manual or Sports Nutrition Care Manual (SNCM). After the responses were collected, supplement categories and product manufacturers were identified for inclusion. Data collection began by visiting manufacturers' web pages and recording nutrition information into a standardized form provided by the web developers at the SNCM. These completed forms were then sent to the Online Publishing Manager at the Academy of Nutrition and Dietetics. This information was then published into a formulary accessible through the SNCM. Results: The survey yielded 111 respondents. The respondents indicated a personal (71%) and client (64%) need for a sports nutrition formulary. The respondents also indicated that they are very likely (51%) or somewhat likely (40%) to use a sports nutrition formulary if it were created. Based on these responses, a formulary was created and published through the SNCM. Conclusion: Version 1.0 of the Sports Nutrition Formulary was published to the SNCM on April 15th, 2013. This formulary offers the ability for dietitians and other health professionals to make the most informed, up to date decision regarding the best SNS for their client.

This study investigated the effects of progressive dehydration by 1.5-2.0% body mass (BM) (NF) on core temperature (Tc), heart rate (HR), on-ice performance, and mental fatigue during a 70-min scrimmage, compared to maintaining BM with a carbohydrate-electrolyte solution (CES). Compared to CES, Tc was significantly higher throughout the scrimmage in NF. Players in NF had reduced mean skating speed and time at high effort between 30-50 min of the scrimmage. Players in NF committed more puck turnovers and completed a lower percentage of passes in the last 20 min of play. Post-scrimmage shuttle skating time was higher in NF. Hockey fatigue questionnaire total score and Profile of Mood States fatigue score was higher in NF. The results indicate that mild dehydration compared to maintaining BM with a CES resulted in increased Tc, decreased skating and puck handling performance, and increased mental fatigue during an ice hockey scrimmage. / Gatorade Sports Science Institute, Natural Sciences and Engineering Research Council of Canada
