Impact of Heat on Dual Task Performance
2026年8月24日 更新者：Louisiana State University Health Sciences Center Shreveport
Impact of Heat Stress and Fatigue on Dual Task Performance-A Pilot Study.
This study looks at how people response performing single and dual tasks (cognitive and motor) prior to and after a rapid heat stress that increased core temperature to 39C.
研究概览
详细说明
Participants will perform single and dual tasks at baseline (normal temperature).
These tasks are cognitive (recall and serial subtraction) and motor (gait and balance).
Then participants will put on firefighter gear and walk on the treadmill in a hot, humid environment until their core temperature reaches 39C.
Then, they will repeat the single and dual tasks with the elevated core temperature.

主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
expanded timed up and go
大体时间：baseline and post-heat stress, both day 1
|
A timed test where participants stand from a chair, walk 10 m, turn, and return to the chair.
Longer times indicate slower gait speed
|
baseline and post-heat stress, both day 1
|
|
Firefighter balance test
大体时间：baseline and post-heat stress, both day 1
|
A timed test where participants walk an obstacle course measuring dynamic balance, having to step up/down, walk a narrow path, and duck under an obstacle.
Longer times indicate worse dynamic balance.
|
baseline and post-heat stress, both day 1
|
|
Backward Digit Recall
大体时间：baseline and post-heat stress, both day 1
|
A timed test where participants recall a series of numbers in reverse order.
More digits indicate better recall.
|
baseline and post-heat stress, both day 1
|
|
Serial Sevens Subtraction
大体时间：baseline and post-heat stress, both day 1
|
A timed test where participants count backwards from a starting value by 7s, with the more correct responses in 20 seconds indicating better cognitive ability for this task.
|
baseline and post-heat stress, both day 1
|
|
Serial Sevens Subtraction-Expanded Timed Up and Go Dual Task
大体时间：baseline and post-heat stress, both day 1
|
Performance of serial sevens subtractions while performing the Expanded timed up and go test (ETUG).
This test is timed (ETUG) and correct responses tabulated (subtraction).
|
baseline and post-heat stress, both day 1
|
|
Serial Sevens Subtraction-Firefighter Balance Test Dual Task
大体时间：baseline and post-heat stress, both day 1
|
Performance of serial sevens subtractions while performing the Firefighter Balance Test (FFBT).
This test is timed (FFBT) and correct responses tabulated (subtraction).
|
baseline and post-heat stress, both day 1
|
|
Backward Digit Recall-Expanded Timed Up and Go Dual Task
大体时间：baseline and post-heat stress, both day 1
|
Performance of backward digit recall while performing the Expanded timed up and go test (ETUG).
This test is timed (ETUG) and correct responses tabulated (Recall).
|
baseline and post-heat stress, both day 1
|
|
Backward Digit Recall-Firefighter Balance Test Dual Task
大体时间：baseline and post-heat stress, both day 1
