Abstract

The purpose of this study was to identify nutrition practices of older athletes that may affect competitive performance and reflect nutrition misinformation. Statewide Senior Games participants (n=100) were surveyed on dietary practices, supplement use and sources of nutrition information. The survey instrument was previewed by an exercise physiologist and gerontology RD for content validity and pretested in a seniors exercise class. Surveys were distributed in registration packets and voluntary return was made to collection boxes at event sites. Mean age of the 38 women and 61 men who responded was 66.6 years (range=50–88). No chronic illness was reported by 47% of the sample. Body mass index was in the acceptable range for 79%. A diet change within the last 5 years was reported by 50%; 24% diet to lose weight. Ninety-four % reported drinking more liquids during activity, though only 11% consumed sports drinks. Forty-two % reported eating more when they were physically active; 47% ate more carbohydrate and 35% ate more protein. Reported supplement use was: 54% multivitamin, 46% vitamin E, 40% vitamin C, 38% calcium, 19% B vitamins, 17% no supplements, 13% herbal preparations, 4% protein drink. Other supplement use included chromium and other minerals, antioxidants (unspecified), pycogenol, garlic, wheat germ. The media and physicians were primary sources of nutrition information. However, when queried separately about sports-related nutrition information media followed by friends and fellow athletes were primary sources. Based on the survey results it appears older athletes show knowledge of fluid and energy needs, are conservative in use of ergogenic supplements and would be well served by accurate information in media sources. Given U.S. demographics, this kind of population of more active seniors may be expected to grow. Their concerns and practices increasingly need to be followed and reflected in the content and delivery of nutrition messages.
