Abstract

Objective:

This cluster-controlled pilot study assessed the efficacy and feasibility of "Fit2Drive,"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 "Fit2Drive"(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 (VO2peak), HIIT session attendance, and delivery costs. 

Results:

Driver clusters allocated to "Fit2Drive"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 Fit2Drive but also highlight challenges for in-person delivery at scale.
