HIRSCHBRUCH, Marcia Daskal; FISBERG, Mauro and MOCHIZUKI, Luis. Supplement use amongst young individuals in São Paulo's fitness centers. Rev Bras Med Esporte [online]. 2008, vol.14, n.6, pp.539-543. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922008000600013.
The concern with physical appearance and aesthetics in fitness centers can lead to an indiscriminate use of supplements. A questionnaire was used to investigate factors relating to supplement use among 201 young users of fitness centers in the city of São Paulo, Brazil. Supplement use was reported by 61.2% (n = 23) of the sample. Men use more supplements than women (p < 0.001) and adolescents tend to use them more than young adults (p = 0.07). The supplements most used by this group are sports drinks (12%); high-calorie "gainers" (12%), amino acids (10%), proteins (10%) and creatine (8%). The supplements are taken trough own initiative (42.8%) and trainers' recommendation (27.5%). Those who have been exercising for a longer time, go more often to the fitness centers, and devote more time to exercise/week are significantly more involved in supplement use. The presence of user friends (p = 0.03) and/or a user at home (p = 0.01) also influences on the use of supplements. Supplement use is a widespread, common practice at fitness centers, whose environment favors their use.
