Impact of Heat on Dual Task Performance Study
This study is looking at how heat stress affects your ability to do two things at once, like walking and thinking. Researchers will have you perform tasks that involve both your body (motor) and your brain (cognitive) before and after your body temperature is raised to 39 degrees Celsius (a fever). This will be done by having you walk on a treadmill in a hot, humid room while wearing firefighter gear. The study is looking for healthy individuals between 18 and 57 years old. Success will be measured by how well you perform balance, walking, and memory tests after being in the heat. The current recruitment status is unclear, and the study plans to enroll 10 participants.
- Study design
- This is an interventional study with 10 planned participants. It is not specified if it is randomized or blinded.
- What's involved
- You will perform cognitive and motor tasks at normal temperature, then walk in a hot environment until your core temperature reaches 39C, and then repeat the tasks. All measurements are taken on Day 1.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your performance on balance, walking, and memory tests will be measured at baseline and immediately after heat stress on Day 1.

What this trial measures
- expanded timed up and gobaseline 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
- Firefighter balance testbaseline 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.
- Backward Digit Recallbaseline 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.
- Serial Sevens Subtractionbaseline 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.
- Serial Sevens Subtraction-Expanded Timed Up and Go Dual Taskbaseline 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).
- Serial Sevens Subtraction-Firefighter Balance Test Dual Taskbaseline 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).
- Backward Digit Recall-Expanded Timed Up and Go Dual Taskbaseline 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).
- Backward Digit Recall-Firefighter Balance Test Dual Taskbaseline and post-heat stress, both day 1
Performance of backward digit recall while performing the Firefighter Balance Test (FFBT). This test is timed (FFBT) and correct responses tabulated (Recall).
