The thermal demands of flood rescue and impacts on task performance
Research output: Contribution to journal › Article
Methods: Ten participants undertook two simulations: ‘Cold’ (4 °C)-participants stood in knee height moving water (4.8km·h−1), with simulated wind and rain for 60 min. ‘Warm’ (20 °C)-participants performed 6x7 min walking in knee height moving water (3.2km·h−1), pulling 10kg. Grip strength, manual dexterity, and jump height were measured pre and post.
Results: The cold resulted in cooling of the great toe and finger (9.98 [0.84]°C and 10.38 [8.21-12.1]°C respectively). Jump height, manual dexterity and grip strength fell by 20%, 22% and ∼13% respectively. In the ‘Warm’: heart rates were 157 (19)b.min−1, oxygen consumption 30.62 (7.83)mL.kg−1.min−1, and sweat loss 1.06 (0.31)L. There were no differences in the physical tests.
Conclusion: Flood Rescue represents significant, but different, challenges. Remaining static in the cold resulted in peripheral neuromuscular cooling, whilst exercising in the warm resulted in significant thermal challenge.
