Study Summary

This trial is testing how different base pack weights affect heart rate and perceived exertion while hiking.

Who is the study for?
This trial is for adults aged 18-65 who enjoy backpacking. Participants should have completed at least two overnight backpacking trips in the last five years and hiked a minimum of 8 miles on one of those occasions. It's not suitable for daily smokers, people with recent lower limb surgeries or injuries, or chronic conditions like heart disease, hypertension, high cholesterol, diabetes, kidney disease, or severe back pain.Check my eligibility
What is being tested?
The study investigates how carrying different weights in a backpack affects exertion and heart rate during a day-long hike. Researchers will use the Borg Rating of Perceived Exertion to measure how hard participants feel they are working as they carry these loads.See study design
What are the potential side effects?
There may be no direct side effects from participating in this study other than the typical physical strain associated with hiking such as muscle soreness or fatigue. However, there's always a risk of injury when engaging in outdoor activities.

Trial Design

2Treatment groups
Active Control
Group I: The Borg Rating of Perceived Exertion between 17 and 19 lb BPWActive Control1 Intervention
Participants will be randomized to both 17 and 19 pounds for the first hike and the alternate condition for the second hike. A random number generator will create 1 block that includes 10 participants in each block to ensure comparable numbers to subjects starting at different base backpack weight. Participants assignments will then be included in a sealed manila envelopes.
Group II: The Borg Rating of Perceived Exertion between 19 and 17 lb BPWActive Control1 Intervention
Participants will be randomized to both 19 or 17 pounds for the first hike and the alternate condition for the second hike. A random number generator will create 1 block that includes 10 participants in each block to ensure comparable numbers to subjects starting at different base backpack weight. Participants assignments will then be included in a sealed manila envelopes.
