Swimming is a critical task for helicopter rescue paramedics and aerobic capacity is assessed in this occupation to determine job suitability. We evaluated one treadmill-based and one pool-based assessment of maximal aerobic capacity (V̇O) in 14 helicopter rescue paramedics. There was a small absolute difference ( = 0.11, = 0.46) between V̇O in the swim (45.5 ± 7.8 ml.kg.min) compared to the run (48.5 ± 5.5 ml.kg.min), with a moderate relationship noted ( = 0.74, 95% CI [0.35-, 0.91], = 0.0023). Whilst not interchangeable, run V̇O was a predictor of swim V̇O. Maximal blood lactate was similar ( = 0.93) in swim (13.4 ± 3.8 mmol.L) and run (12.2 ± 3.0 mmol.L), and maximal heart rate 13% lower ( < 0.0001) in the swim (162 ± 11 bpm) versus the run (186 ± 10 bpm). To estimate swimming V̇O in paramedics a treadmill test is sufficient but does not replace assessment of swimming proficiency. : We developed a swim protocol to assess maximal aerobic capacity in helicopter rescue paramedics. Compared to a treadmill-based test, our swim protocol generated 20% lower submaximal V̇O and 6% lower V̇O. Although not interchangeable, a treadmill V̇O test is indicative of maximal aerobic capacity in rescue paramedics whilst swimming.

游泳对于直升机救援医护人员来说是一项关键任务，而有氧运动能力是评估其职业适应性的一个指标。我们评估了 14 名直升机救援医护人员的一种基于跑步机和一种基于泳池的最大有氧能力（V̇O）评估。在游泳（45.5±7.8 ml.kg.min）和跑步（48.5±5.5 ml.kg.min）中，V̇O 之间存在很小的绝对差异（ = 0.11， = 0.46），并注意到中度关系（ = 0.74，95%CI [0.35-0.91]， = 0.0023）。虽然不能互换，但跑步 V̇O 可以预测游泳 V̇O。最大血乳酸在游泳（13.4±3.8 mmol.L）和跑步（12.2±3.0 mmol.L）中相似（ = 0.93），最大心率在游泳中低 13%（ < 0.0001）（162±11 bpm）与跑步（186±10 bpm）。要估计医护人员的游泳 V̇O，跑步机测试是足够的，但不能替代游泳能力的评估。 ：我们开发了一种游泳方案来评估直升机救援医护人员的最大有氧能力。与基于跑步机的测试相比，我们的游泳方案产生的次最大 V̇O 低 20%，V̇O 低 6%。虽然不能互换，但跑步机 V̇O 测试可以指示救援医护人员在游泳时的最大有氧能力。 HEMS：直升机紧急医疗服务；PES：物理就业标准；ICFP：重症监护飞行医护人员；RPE：感知用力等级。
