|
This study compared the pattern of purchasing nutritional supplements and obtaining nutrition information and the Nutrition Quotient of adults who exercise regularly according to the frequency of muscle training(LM, muscle training less than two days/week; MM, 2∼3 days/week; HM, more than three days/week). Compared to the other groups, significantly more men in the HM group answered that they had purchased supplements and would repurchase them. They presented “increasing muscle mass” as the purpose of buying them and “types and contents” as the major factor to consider before buying. The supplements that significantly more subjects in the HM group purchased than in the other groups were protein supplements, BCAA (Branched-chain amino acid), arginine, and caffeine supplements for men and protein supplements, BCAA and carnitine for women. Compared to the other groups, significantly more men and women in the HM group reported “trainer” as the major source of nutrition information, and significantly more men in the HM group reported “increasing muscle mass” as the 1st topic of nutrition education that they wanted to receive and were satisfied with the information that they obtained. Most of all, males and females in the HM group had significantly a higher Nutrition Quotient than in the other groups. The differences between males and females in variables regarding exercise, the patterns of using supplements and acquiring nutrition information, and Nutrition Quotient were also found. These results can provide basic data for developing educational materials emphasizing the wise consumption of nutrition information, including supplement intake.
