To evaluate the change in Balance Error Scoring System (BESS) performance after an athletic season.
A prospective longitudinal group study.
University biomechanics research laboratory.
A total of 58 college-aged females (23 soccer student-athletes, 16 volleyball student-athletes, and 19 recreationally active healthy college students) participated in the study.
The BESS test was administered on 2 occasions 90 days apart. For the student-athletes, the first test (PRE) was administered before the start of their athletic season and the second test (POST) was administered immediately after the season. For the recreationally active college students, the PRE test was at the beginning of the academic semester and the POST test exactly 90 days thereafter.
Total BESS score at PRE and POST was compared with a 3 × 2 repeated measures analysis of variance. The overall change score and absolute value change score were also calculated and compared with a 1-sample t test to an expected change of zero errors.
There was no group by time interaction; however, there was a main effect for time. There was a significant improvement (P = 0.003) between PRE (9.00 ± 2.97 errors) and POST (7.92 ± 2.78 errors) BESS performance. There were significant differences for both the overall change score (1.08 errors) and the absolute value change score (2.00 errors).
A clinically and statistically significant difference in BESS performance was identified after a 90-day intercollegiate athletic season.
评估运动赛季后平衡错误评分系统（BESS）表现的变化。
前瞻性纵向组研究。
大学生物力学研究实验室。
共有 58 名大学年龄的女性（23 名足球运动员、16 名排球运动员和 19 名经常参加体育活动的健康大学生）参加了这项研究。
BESS 测试在 90 天内进行了 2 次。对于运动员，第一次测试（PRE）在运动赛季开始前进行，第二次测试（POST）在赛季结束后立即进行。对于经常参加体育活动的大学生，PRE 测试在学术学期开始时进行，POST 测试正好在 90 天后进行。
PRE 和 POST 的总 BESS 评分与 3×2 重复测量方差分析进行比较。还计算了总体变化得分和绝对值变化得分，并与 1 个样本 t 检验进行比较，以期望误差为零。
没有组间时间的相互作用；然而，时间有一个主要作用。BESS 表现的 PRE（9.00±2.97 个错误）和 POST（7.92±2.78 个错误）之间有显著的改善（P=0.003）。总体变化得分（1.08 个错误）和绝对值变化得分（2.00 个错误）都有显著差异。
在 90 天的大学间运动赛季后，BESS 表现有临床和统计学上的显著差异。
