When people undertake a multi-day or thru-hike, some tend to believe that they’ll ‘get their trail legs’ and be fine after a few days. Sure, maybe they’ll be sore initially, but they figure they’ll get stronger as they go. One study from Brazil proves this isn’t likely(1).
Researchers sent 26 experienced hikers on a four-day backpacking trip. The investigators controlled for many factors affecting the hikers, including sleep, diet, rest, and terrain. At the end of each hiking day, the researchers measured each hiker’s postural sway on a force platform with eyes open. The postural sway changes were significant after each day’s hike, with the biggest difference observed on the third day, which was the longest and most challenging hiking day.
Increased postural sway means that you’ll move further away from your center of mass before you correct and return yourself to upright. Fatigued muscles increase your postural sway and your risk of falling. This study shows that multiple days on the trail don’t ‘train’ you but actually may put you more at risk for injury(1). Additionally, sore muscles and blisters, common the first few days on the trail, also negatively impact balance(1).
The muscles that demonstrated the greatest fatigue after hiking were muscles around the ankle and hip. These weary muscles impacted balance in the anterior-posterior direction, while the muscles surrounding the knee and hip impaired balance in the medial-lateral direction. As the muscles around the ankle tire, their activation pattern changes, which is likely why most ankle sprains happen toward the end of a hike when you’re nearing camp or heading back to the trailhead.
How do you avoid increased postural sway and decreased balance?
