The purpose of the present investigation was to study the use of supplements in a large group of endurance runners (no. = 347) who had participated in the 1987 Los Angeles Marathon. Three-day dietary records were analyzed for nutrient content and supplement usage. The runners' supplementation patterns with respect to demographics, dietary quality, training habits, and race performance were investigated. In general, no significant associations were found between supplement use and the aforementioned variables. Use of supplements, especially vitamins C and E, calcium, and zinc, increased with age (p less than .05). Daily use of at least one type of supplement was reported by 29% of the runners; 48% reported use of at least one type of supplement within the 3-day period.
本研究的目的是调查一大群参加1987年洛杉矶马拉松赛的耐力跑运动员（n = 347）使用补充剂的情况。对三天的饮食记录进行了营养成分和补充剂使用情况分析。研究了跑步者在人口统计学、饮食质量、训练习惯和比赛成绩方面的补充剂使用模式。总体而言，未发现补充剂使用与上述变量之间存在显著关联。补充剂的使用，尤其是维生素C和E、钙和锌的使用，随年龄增长而增加（p < 0.05）。29%的跑步者报告每天至少使用一种补充剂；48%的跑步者报告在三天内至少使用一种补充剂。
