Objective To investigate if a combination of an online and onsite implementation strategy was superior to an online-only strategy in enhancing the use of an injury prevention exercise programme (IPEP) and in reducing the risk of shoulder, knee and ankle injuries in youth community handball players (age 11–17) over a handball season. Methods In this 30-week hybrid effectiveness-implementation cluster randomised type 3 study, 20 youth handball clubs were randomly assigned 1:1 to either a combined online and onsite implementation strategy (coach workshop using the health action process approach behaviour change model and health service provider (HSP) support) or an online-only strategy (control group). The primary implementation outcome was coach-reported adherence, measured as the average IPEP exercise usage by the team over 30 weeks. The primary effectiveness outcome was player-reported handball playing time to any new handball-related shoulder, knee and ankle injuries, reported weekly using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems. Results We enrolled 63 coaches (27% women) and 945 players (mean age 14.5 years, 55% girls). Intention-to-treat analyses showed no statistically significant difference between implementation strategies in adherence (between-group difference 1.4, 95% CI −0.5 to 3.4) or in cumulative injury risk (between-group difference 5.5% points, 95% CI −2.2 to 13.1). Conclusion Our findings demonstrate that in youth community handball, a combined online and onsite implementation strategy, including a coach workshop and HSP support, was not superior to an online-only strategy regarding adherence to an IPEP or in reducing shoulder, knee and ankle injury risk.

青少年健康与表现促进 （HAPPY） 混合有效性实施整群随机试验：在丹麦青少年手球中实施伤害预防锻炼计划的两种策略的比较


目的 调查在线和现场实施策略的组合是否优于纯在线策略，以加强伤害预防锻炼计划 （IPEP） 的使用以及降低青年社区手球运动员（11-17 岁）在手球赛季中受伤的风险。方法 在这项为期 30 周的混合有效性-实施整群随机 3 型研究中，20 个青年手球俱乐部被 1：1 随机分配到在线和现场相结合的实施策略（使用健康行动过程方法行为改变模型和健康服务提供商 （HSP） 支持的教练研讨会）或仅在线策略（对照组）。主要实施结果是教练报告的依从性，以团队在 30 周内的平均 IPEP 锻炼使用情况来衡量。主要有效性结果是球员报告的手球比赛时间对任何新的手球相关肩部、膝盖和脚踝损伤的影响，每周使用奥斯陆运动创伤研究中心健康问题问卷报告。结果我们招募了 63 名教练 （27% 为女性） 和 945 名球员 （平均年龄 14.5 岁，55% 为女孩）。意向治疗分析显示，实施策略在依从性（组间差异 1.4,95% CI -0.5 至 3.4）或累积伤害风险（组间差异 5.5% 分，95% CI -2.2 至 13.1）方面没有统计学意义差异。结论我们的研究结果表明，在青年社区手球中，在线和现场相结合的实施策略，包括教练研讨会和 HSP 支持，在遵守 IPEP 或降低肩部、膝盖和踝部受伤风险方面并不优于纯在线策略。试验注册号 [NCT05294237][1]。 数据可应合理要求提供。在数据传输之前，所有个人身份信息都将被删除或匿名化。[1]： /lookup/external-ref？link_type=CLINTRIALGOV&access_num=NCT05294237&atom=%2Fbjsports%2F58%2F20%2F1205.原子
