Abstract
The use of nutritional supplementation amongst athletes has been increasing over the
past decade. The aim of this study investigated the use of nutritional supplements
amongst athletes participating in 1st team sports at the University of Johannesburg. This
research was a quantitative, descriptive statistical survey design study consisting of 187
athletes from a variety of sporting disciplines at UJ. All the participants were met at their
prearranged area after consulting with their coaching staff. Participation was voluntary
and consent was given by the participants prior to completing the questionnaire. The data
from the questionnaires was captured and analysed with the assistance of STATKON,
UJ, by using custom tables, frequencies, and Chi-Square analysis. The results suggest
that more than half of the participants make use of nutritional supplements to enhance
their sporting performance. There is no statistical significance between gender uses of
supplements, just to the type of supplements being used. Males more likely using
supplements such as creatine and mass gainers, where females more likely using weight
loss supplements and vitamins. The majority of the participants receive their information
regarding supplements from friends, team mates, and pharmacy assistants, rather than
more reputable sources such as healthcare practitioners or medical books and journals.
The most popular supplements being used by the participants were protein supplements
and minerals, vitamins, and amino acids. Testosterone boosters and nitric oxide
supplements proved the least popular choices. There is a definite need for educational
programs and awareness campaigns at the university to educate the athletes regarding
the benefits and harms of supplement use.
