Prevention of exercise-related leg pain (ERLP) has not been successful because ERLP risk factors are not well known.
To determine the percentage of high school cross-country (XC) athletes who reported a history of ERLP in their running careers, to identify the percentage of athletes who reported an occurrence of ERLP during 1 XC season, and to investigate the association of selected factors (age, high school year, years of high school running, sex, ERLP history, body mass index [BMI], foot type, and training distance) and the occurrence of ERLP.
Prospective cohort study.
Six local high schools.
One hundred twenty-five high school XC athletes (62 females, 63 males).
MAIN OUTCOME MEASURE(S): All athletes completed an initial ERLP questionnaire, and foot type was visually assessed. After the season, athletes were asked to complete a Web-based questionnaire regarding the seasonal occurrence of ERLP. Statistical analyses of differences (t tests) and associations (chi(2), relative risk) were conducted.
A total of 103 of the 125 athletes (82.4%) reported a history of ERLP, with 81 athletes reporting ERLP occurrence within the month preceding completion of the initial questionnaire. Bilateral medial leg pain was the most common ERLP presentation. More than half of the athletes (58.4%) with an ERLP history reported that the pain had interfered with XC participation. Ninety-three athletes responded to the postseason questionnaire, and 45 (48.0%) reported ERLP seasonal occurrence. Most athletes (97.8%) who experienced the seasonal occurrence of ERLP had a history of ERLP. No associations were noted between ERLP history or seasonal occurrence and age, high school year, years of high school running, sex, BMI, foot type, or training distance.
Both a history of ERLP and the seasonal occurrence of ERLP were common among these XC athletes. The only risk factor identified for ERLP season occurrence was ERLP history.
预防与运动相关的腿部疼痛（ERLP）尚未成功，因为 ERLP 的风险因素尚不清楚。
确定报告在跑步生涯中曾有 ERLP 病史的高中越野（XC）运动员的百分比，确定报告在 1 个 XC 赛季中发生 ERLP 的运动员的百分比，并调查选定因素（年龄、高中年级、高中跑步年限、性别、ERLP 病史、体重指数[BMI]、足型和训练距离）与 ERLP 发生的关联。
前瞻性队列研究。
六所当地高中。
125 名高中 XC 运动员（62 名女性，63 名男性）。
所有运动员均完成了初始 ERLP 问卷，并且对足型进行了视觉评估。赛季结束后，运动员被要求完成一份关于季节性 ERLP 发生情况的基于网络的问卷。进行了差异（t 检验）和关联（卡方、相对风险）的统计分析。
在 125 名运动员中，共有 103 名（82.4%）报告了 ERLP 病史，其中 81 名运动员在完成初始问卷前一个月报告了 ERLP 发生。双侧腿部内侧疼痛是最常见的 ERLP 表现。超过一半（58.4%）有 ERLP 病史的运动员报告说疼痛影响了 XC 参赛。93 名运动员回答了赛后问卷，其中 45 名（48.0%）报告了 ERLP 季节发生。大多数经历过 ERLP 季节发生的运动员（97.8%）都有 ERLP 病史。ERLP 病史或季节性发生与年龄、高中年级、高中跑步年限、性别、BMI、足型或训练距离之间没有关联。
在这些 XC 运动员中，ERLP 病史和 ERLP 季节性发生都很常见。唯一确定的 ERLP 季节发生的危险因素是 ERLP 病史。
