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.

项目总结/摘要 消防部门是职业伤害发生率最高的部门之一，造成了巨大的经济负担。 心源性猝死、滑倒、绊倒、福尔斯摔倒和过度用力引起的拉伤和扭伤也经常被提及 是最常见的致命和非致命伤害。最近的研究表明，高强度间隔 训练（HIIT）和多因素神经肌肉训练计划，包括动态拉伸，核心 稳定性、平衡和健身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，与那些行使值班经历了惊人的高利率的运动相关的 受伤此外，只有27%的消防部门实施了健身计划， 需要改进安全和循证运动的实施工作，以解决 坚持现场锻炼。我们团队的初步工作表明， （培训师）模式，包括专业监督，可以降低类似人群（即 军校学员）。本提案的目的是确定可行性并获得初步的 训练员提供的综合训练程序的初始变化和干预保真度的数据 （包括神经肌肉热身和HIIT）。主要的假设是，消防队员将 按照预期遵守培训师提供的综合锻炼计划，并将表现出临床重要性 改善心血管疾病（CVD）和拉伤及扭伤的主要危险因素。两个- 将进行一项为期6周的TRAINER干预的随机分组可行性和概念验证研究， 由40名职业消防员组成的消防站进行。这项研究是创新的，因为1）它包括一个 促进值班锻炼坚持性并针对主要致命和非致命伤害的锻炼策略 在消防服务，和2）探讨了一种新的使用培训模式，以改善执行工作， 消防站的演习计划在目标1中，我们的多学科小组将研究 培训师在消防员中提供综合训练计划。我们将决定招聘和保留 率，随机化的意愿，以及对6周干预的依从性和可接受性。在 目标2，我们将确定干预保真度和心血管疾病和紧张的风险因素的短期变化， 扭伤这一创新项目的预期产出和成果对进一步研究至关重要， 在消防服务中的实践（r2 p）努力。此外，这款R 03的独特优势包括： 来自领先的战术健身组织，拥有全国认证的健身专业人士网络， 在未来的大规模试验中，将该项目推广到全国。该提案直接针对3 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CVD、肌肉骨骼损伤和跌倒相关损伤。
