PROJECT SUMMARY/ABSTRACT The fire service has one of the highest rates of occupational injuries incurring a large economic burden. Sudden cardiac death, and strains and sprains from slips, trips and falls and overexertion are frequently cited as the most common fatal and non-fatal injuries. Recent research has demonstrated that high-intensity interval training (HIIT) and multi-factorial neuromuscular training programs that include dynamic stretching, core stability, balance, and medicine ball exercises can specifically target the primary risk factors of these injuries, while improving firefighter performance. However, 75% of firefighters fail to achieve minimum physical activity recommendations, with those exercising on-duty experiencing surprisingly high rates of exercise-related injuries. In addition, with only 27% of fire departments implementing fitness programs, novel strategies are needed to improve implementation efforts of safe and evidence-based exercise that address key barriers to worksite exercise adherence. Preliminary work from our team has demonstrated that a ‘train-the-trainer’ (TRAINER) model, including professional supervision, can reduce the risk of injury in similar populations (i.e. military cadets). The objective of the current proposal is to determine the feasibility and obtain preliminary data on the initial changes and intervention fidelity to a TRAINER delivered integrated exercise routine (including a neuromuscular warm-up and HIIT) at fire stations. The main hypotheses are that firefighters will adhere to the TRAINER delivered integrated exercise program as intended and will exhibit clinically important improvements in primary risk factors for cardiovascular disease (CVD) and strain and sprain injuries. A two- arm cluster randomized feasibility and proof-of-concept study of a 6-week TRAINER intervention will be conducted with 40 career firefighters clustered by fire station. This study is innovative because 1) it includes an exercise strategy that facilitates on-duty exercise adherence and targets the primary fatal and non-fatal injuries in the fire service, and 2) explores a novel use of the TRAINER model to improve the implementation efforts of exercise programs at fire stations. In Aim 1, our multidisciplinary team will examine the feasibility of the TRAINER delivered integrated exercise program in firefighters. We will determine recruitment and retention rates, the willingness to be randomized, and the adherence to and acceptability of the 6-week intervention. In Aim 2, we will determine intervention fidelity and short-term changes in risk factors for CVD and strain and sprain injuries. The expected outputs and outcomes of this innovative project are critical to further Research to Practice (r2p) efforts in the fire service. Furthermore, a unique strength of this R03 includes the strong support from a leading tactical fitness organization with a national network of certified fitness professionals to enhance the dissemination of this project nationwide in a future large-scale trial. This proposal directly addresses 3 primary strategic goals (# 1,3, and 6) outlined in the Public Safety sector and cross-sector agenda items that include the reduction of CVD, musculoskeletal injuries, and fall-related injuries.

项目摘要/摘要 消防部门是职业伤害率最高的部门之一，造成了巨大的经济负担。 心脏猝死，以及因滑倒、绊倒、摔倒和过度劳累而造成的劳累和扭伤经常被引用 最常见的致命性和非致命性伤害。最近的研究表明，高强度间歇 训练(HIIT)和多因素神经肌肉训练计划，包括动态伸展，核心 稳定性、平衡性和药球练习可以特别针对这些损伤的主要危险因素， 同时提高消防员的表现。然而，75%的消防员未能达到最低限度的体力活动 建议，那些在值班锻炼的人经历了令人惊讶的高锻炼相关比率 受伤。此外，由于只有27%的消防部门实施了健身计划，新的策略是 需要改进安全和循证演习的实施工作，以解决以下关键障碍 坚持工作场所锻炼。我们团队的初步工作表明，一名“训练员” (培训者)模式，包括专业监督，可以减少类似人群(即 军校学员)。目前提案的目标是确定可行性并取得初步成果。 关于初始变化和对教练提供综合锻炼计划的干预保真度的数据 (包括神经肌肉热身和HIIT)。主要的假设是消防员会 坚持训练师提供的综合锻炼计划，并将显示出临床重要性 心血管疾病(CVD)以及劳损和扭伤的主要危险因素的改善。两个人- 为期6周的训练员干预的ARM集群随机可行性和概念验证研究将是 对消防局聚集的40名职业消防员进行了调查。这项研究是创新的，因为1)它包括一个 有助于坚持值班锻炼并针对主要致命性和非致命性伤害的锻炼策略 以及2)探索了培训员模式的新用途，以改进 消防局的演习计划。在目标1中，我们的多学科小组将研究 培训师为消防员提供综合训练计划。我们将决定招聘和留住 利率，随机化的意愿，以及对6周干预的坚持和可接受性。在……里面 目的2，我们将确定干预保真度和心血管疾病和应激反应危险因素的短期变化。 扭伤。这一创新项目的预期产出和结果对于进一步研究 在消防服务中实践(R2P)努力。此外，这款R03的独特优势包括强大的支持 来自领先的战术健身组织，拥有全国认证的健身专业人员网络，以增强 该项目的推广将在未来的全国范围内进行大规模的试验。该提案直接涉及3个问题 公共安全部门和跨部门议程项目中概述的主要战略目标(#1、3和6) 包括减少心血管疾病、肌肉骨骼损伤和与跌倒相关的损伤。
