Summary
The aim of this project is to increase knowledge on and influence intention (and related determinants) toward the use of dietary supplements in populations at risk for doping such as university student athletes. Our objectives are to increase athletes' knowledge on dietary supplements, change their attitude, subjective norms and perceived behavioural control toward the use of these supplements, increase their body appreciation and thus increase their intention to take nutrients from diet first before considering dietary supplements. We are proposing the conceptualization, implementation, and evaluation of a nutrition education program on dietary supplements targeting varsity athletes at universities across Ontario.
Participants will be recruited from varsity teams at the University of Guelph. The intervention will be tested for validity and reliability and implemented online through Courselink modules over 4 weeks. Participants will be randomly assigned to a control or intervention group, using a randomized control trial approach. Each week, participants will learn about a topic related to nutrition, health and values-based ethics of clean sport. The intervention group will receive additional information on dietary supplements, their benefits and their risks. Doping and body appreciation and their links to the use of dietary supplements will also be covered in this group. A questionnaire assessing outcome objectives will be administered before and at the end of the intervention as well as 3 months post-intervention. Among the different components covered in the questionnaire, one section will assess knowledge on health, sports nutrition, and dietary supplements; and another will gather responses to statements reflecting the different theory of planned behaviour (TPB) cognitive constructs.
Primary Outcome
