Official title

Impact of Heat Stress and Fatigue on Dual Task Performance-A Pilot Study.

Overview

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.

Detailed description

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.

Interventions

  • Other heat stress
    participants will walk in a heat chamber to increase core temperature

Primary outcome measures

  • expanded timed up and go [Time frame: baseline and post-heat stress, both day 1]
  • Firefighter balance test [Time frame: baseline and post-heat stress, both day 1]
  • Backward Digit Recall [Time frame: baseline and post-heat stress, both day 1]
  • Serial Sevens Subtraction [Time frame: baseline and post-heat stress, both day 1]
  • Serial Sevens Subtraction-Expanded Timed Up and Go Dual Task [Time frame: baseline and post-heat stress, both day 1]
  • Serial Sevens Subtraction-Firefighter Balance Test Dual Task [Time frame: baseline and post-heat stress, both day 1]
  • Backward Digit Recall-Expanded Timed Up and Go Dual Task [Time frame: baseline and post-heat stress, both day 1]
  • Backward Digit Recall-Firefighter Balance Test Dual Task [Time frame: baseline and post-heat stress, both day 1]
