BACKGROUND/AIMS: There is a paucity of prospective cohort studies investigating the incidence of low back pain (LBP) in rowing. We investigated (1) the prevalence and incidence of LBP among international-level rowers in New Zealand, (2) the relationship between training volume and LBP and (3) the effect of LBP on rowers' ability to train and compete.
This was a prospective cohort study of 76 New Zealand representative rowers, including 46 men (mean age 22, SD=4) and 30 women (mean age 21, SD=4). Data were collected using an online questionnaire repeated monthly for 12 months.
The prevalence of LBP ranged from 6% to 25% throughout the year. The incidence of episodes of LBP was 1.67 per 1000 exposure-hours. A total of 72 episodes of LBP were reported by 40 rowers (53%) during 12 months. Of these, 45% had an incidental effect on training. 29% minor, 18% moderate and 9% had a major effect as determined by the length of time the training was interrupted. There was a high correlation between new LBP and total training hours per month (r=0.83, p<0.01). A previous history of LBP was a risk factor in developing new LBP (OR 2.06, 95% CI 1.22 to 3.48, p=0.01). Age was also a risk factor, with the likelihood of developing LBP increasing for every year (OR 1.08, 95% CI 1.01 to 1.15, p=0.02).
LBP is common among New Zealand representative rowers. There is a high correlation between training load and the development of LBP.
背景/目的：针对划船运动员腰痛（LBP）发病率的前瞻性队列研究较少。我们调查了（1）新西兰国际级划艇运动员 LBP 的患病率和发病率，（2）训练量与 LBP 的关系，以及（3）LBP 对划艇运动员训练和比赛能力的影响。
这是一项针对 76 名新西兰代表性划艇运动员的前瞻性队列研究，其中包括 46 名男性（平均年龄 22 岁，标准差=4）和 30 名女性（平均年龄 21 岁，标准差=4）。使用在线问卷逐月重复收集 12 个月的数据。
全年 LBP 的患病率在 6%至 25%之间。LBP 发作的发病率为每 1000 暴露小时 1.67 次。在 12 个月期间，40 名运动员报告了 72 次 LBP 发作（53%）。其中，45%对训练有偶发影响。29%为轻度、18%为中度、9%为因中断训练时间而造成严重影响。新发 LBP 与每月总训练时间高度相关（r=0.83，p<0.01）。LBP 的既往史是新发 LBP 的危险因素（OR 2.06，95%CI 1.22 至 3.48，p=0.01）。年龄也是一个危险因素，LBP 的发病几率随着年龄的增长而增加（OR 1.08，95%CI 1.01 至 1.15，p=0.02）。
LBP 在新西兰代表性划艇运动员中很常见。训练负荷与 LBP 的发展高度相关。
