OBJECTIVE
This cluster-controlled pilot study assessed the efficacy and feasibility of "Fit 2 Drive," a depot-delivered, high-intensity interval training (HIIT) program to improve the cardiorespiratory fitness (CRF) of truck drivers.
METHODS
Companies of local delivery drivers (44 men; mean [SD] age = 50.5 [9.8] years; Brisbane, Australia) were assigned to "Fit 2 Drive" (4 clusters; 27 drivers; 1 × 4 minutes supervised to self-managed HIIT, 3 times a week, 12 weeks) or a control (5 clusters; 17 drivers). Analyses assessed between group changes in CRF (VO 2peak ), HIIT session attendance, and delivery costs.
RESULTS
Driver clusters allocated to "Fit 2 Drive" significantly improved CRF compared to a control (mean difference of 3.6 mL·kg -1 ·min -1 ; P < 0.019; 95% confidence interval = 0.7-6.5 mL·kg -1 ·min -1 ). Drivers who completed the program attended 70% of sessions (25/36) with delivery costs averaging $710 AUD per driver.
CONCLUSIONS
The findings support the efficacy and feasibility of Fit 2 Drive but also highlight challenges for in-person delivery at scale.
目的
本群组对照试验性研究评估了“Fit 2 Drive”的有效性和可行性，这是一种通过长效注射给药的高强度间歇训练（HIIT）计划，旨在提高卡车司机的心肺适能（CRF）。
方法
当地送货司机公司（44名男性；平均[标准差]年龄 = 50.5[9.8]岁；澳大利亚布里斯班）被分配到“Fit 2 Drive”组（4个群组；27名司机；每周3次，每次1×4分钟，从有监督的训练过渡到自我管理的HIIT，共12周）或对照组（5个群组；17名司机）。分析评估了两组之间在心肺适能（VO₂峰值）、HIIT课程出勤率和送货成本方面的变化。
结果
与对照组相比，分配到“Fit 2 Drive”的司机群组心肺适能显著提高（平均差异为3.6 mL·kg⁻¹·min⁻¹；P < 0.019；95%置信区间 = 0.7 - 6.5 mL·kg⁻¹·min⁻¹）。完成该计划的司机参加了70%的课程（25/36），每位司机的送货成本平均为710澳元。
结论
研究结果支持“Fit 2 Drive”的有效性和可行性，但也凸显了大规模现场授课面临的挑战。
