The physiological demand of pulling a rescue sled across the mud and the impact experience has on this task.
BACKGROUND: To establish a Physical Employment Standard for tasks with high physical demands, it is important to determine the physiological requirements. One such task for the UK Coastguard is mud rescue. OBJECTIVE: To quantify the physiological demand of pulling a rescue sled across estuary mud, a...

One such task for the UK Coastguard is mud rescue. OBJECTIVE: To quantify the physiological demand of pulling a rescue sled across estuary mud, and determine whether rescuer experience has an impact on the physiological demand of this task. METHODS: Forty participants walked 150m in 3 minutes across estuary mud. Following 3 minute rest, they walked 150m pulling a rescue sled (61 kg) in pairs (based on experience). RESULTS: Experienced rescuers had a total oxygen consumption approximately 24% lower than those inexperienced in the task. Relative oxygen consumption (VO2) was significantly (p < 0.05) greater in the non-experienced (mean [SD]; 42.90 [6.55] mL.kg-1.min-1) compared to the experienced group (32.85 [5.79] mL.kg-1.min-1) when controlled for pace. Required VO2 for various speeds were predicted based on non-experienced participants and assessed for agreement. LoA (95%) mean±difference was 0.0003±3.48 mL.kg-1.min-1, with a CV of 2.30%. CONCLUSIONS: For tasks that require a high relative VO2, such as mud rescue, the minimum level of fitness at entry should be based upon the metabolic demands measured on those who are inexperienced. pubtype: Academic Journal doctype: equations & formulas pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
