Why Downhill Walking Poses a Greater Injury Risk Than Uphill—and How to Protect Yourself

The Surprising Risks of Descending

While hiking uphill is undoubtedly the more intense cardiovascular challenge, physical therapy expert and exercise physiologist Dr. Milica McDowell suggests that the descent is actually the phase of your walk most prone to injury. Although walking downhill may feel less physically demanding on your heart and lungs, it places unique and significant strain on your musculoskeletal system.

Understanding Eccentric Contraction

The core of the issue lies in how your muscles function during a descent. According to Dr. McDowell, moving downhill forces your muscles into an eccentric contraction. Unlike concentric movements, where muscles shorten during activity, eccentric contractions occur as the muscle lengthens while under tension.

As Dr. McDowell explains: «Going downhill requires that you're managing your bodyweight, and the additional effects of gravity on your bodyweight. This is more demanding than going uphill.»

Because most common fitness routines emphasize the shortening phase of muscle movement (like the lifting motion of a bicep curl), the body is often less conditioned for the lengthening phase required when walking down a slope. This is precisely why downhill hiking frequently leads to significant muscle soreness.

Building Eccentric Strength

You can prepare your body to handle these forces by specifically training for eccentric strength. Consider these strategies:

• Incorporate controlled movements: Focus on slow, deliberate lowering during exercises like squats, lunges, and step-downs.
• Treadmill training: If available, use a treadmill with a decline feature. Alternating between flat and downhill settings can help build tolerance for the specific demands of a descent.

Techniques for a Safer Descent

Beyond building strength, how you approach the trail makes a significant difference in injury prevention. Dr. McDowell recommends the following tactical adjustments:

• Mind your heel contact: Think of your heel as a brake. Increasing the strength of your heel contact with the ground effectively helps you control your momentum.
• Utilize a zigzag path: If the incline is steep, avoid walking straight down. Zigzagging helps reduce the impact angle for each step.
• Use walking poles: Properly adjusted trekking poles act as an additional set of brakes, providing extra stability and reducing the stress placed on your joints.
