Clinical Trial Summary

Backpacking is an increasingly popular outdoor recreational activity. The base pack weight (BPW) includes gear that is not consumed or worn on the body: shelter, sleep system, weather-proofing layers and personal gear to ensure a degree of comfort and safety. As such, reducing BPW is one of the most important tasks a backpacker manages when preparing for a trip. Available recommendations for ideal BPW are currently inconsistent, lack clear parameters, and rely on anecdotal evidence. The study aims to collect field data on perceived exertion and heart rate (HR) in relation to BPW during a day-long interval of hiking. Such findings can have implications on the cost and safety profiles extending from recreational backpacking to military and wilderness rescue operations.

Outcome

Type Measure Description Time frame Safety issue
Primary The Borg Rating of Perceived Exertion During the Total Hike Participants will report their perceived exertion towards the end of both hikes. The Borg Rating of Perceived Exertion scale ranges from 6 to 20. 6 being the lowest score of no exertion and 20 being the highest of maximal exertion. 2 weeks
Secondary Heart Rate Difference between participants' heart rate during both 17 and 19 pound base backpack weight. 2 weeks
Secondary The Borg Rating of Perceived Exertion During Incline and Decline Sections of the participant Participants will report the perceived exertion mid-hike and towards the end. The Borg Rating of Perceived Exertion scale ranges from 6 to 20. 6 being the lowest score of no exertion and 20 being the highest of maximal exertion. 2 weeks
