Clinical Trial 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.
Description:
High prevalence rates of dietary supplement use are consistently reported across sports
disciplines in the athletic population, and this behaviour can be problematic. The use of
non-prohibited dietary supplements and of doping substances are interrelated: 1) some dietary
supplements are ''contaminated'' with substances prohibited by the World Anti-Doping Agency,
leading to cases of inadvertent doping; and 2) supplement users are more favourable toward
and more likely to engage in doping use. Many athletes derive their supplement-related
information from less reliable sources as shown in a pilot study conducted by our research
team on supplementation practices of varsity athletes at the University of Guelph. Also,
58.6% of those athletes mentioned wanting to become more knowledgeable about supplements.
Given the findings from our pilot study, the association between dietary supplement use and
risk for doping and the frequent reporting of doping rule violation among competing athletes
across all types of sports in Canada, it is imperative to educate athletes about the
appropriate use of dietary supplements.

This study will advance knowledge on dietary supplements and will support the integration of
reliable educational materials on supplements into the training schedules of varsity athletes
at the University of Guelph. Findings from this project will also guide the development of
dietary supplement-focused educational programs at national and international levels to
advance the fight against doping in sports.
