For competitive and recreational runners alike, volume is king—but it comes at a cost. As mileage increases, so does the risk of overuse injuries. At Princeton Sports and Family Medicine, P.C. in Lawrenceville, New Jersey, we use the AlterG Anti-Gravity Treadmill to help runners balance their need for mileage with a smarter approach to stress management.
By strategically integrating AlterG sessions into weekly training plans, high-mileage runners can preserve volume, maintain aerobic fitness, and reduce cumulative tissue load—a recipe for staying healthy and consistent.
The Overuse Equation: Load vs. Recovery
Most running injuries aren’t traumatic—they’re the result of repeated microtrauma that outpaces the body’s ability to adapt. Common overuse issues include:
-
Tibial stress reactions or stress fractures
-
Achilles or patellar tendinopathy
-
Plantar fasciitis
-
IT band syndrome
-
Bone marrow edema
-
Early joint irritation in the knees or hips
As weekly volume increases, so does the cumulative impact on joints, tendons, and muscles. The key to injury prevention isn’t just rest—it’s load management.
How the AlterG Works
The AlterG uses air pressure to reduce effective bodyweight while running—anywhere from 20% to 100% load. That means a 150-pound runner can run at an “effective” weight of 120 pounds or less, decreasing impact forces by up to 80% while maintaining natural running mechanics.
This allows for:
-
Reduced joint and soft tissue stress
-
Maintenance of cadence and form
-
Sustained aerobic intensity without fatigue buildup
-
Fewer missed days due to soreness or flare-ups
Strategic Integration: When to Use the AlterG
▶️ Recovery Runs
Replace a standard recovery run with a 45-minute session at 70–80% bodyweight. You'll still get the aerobic benefit while sparing your legs from extra pounding.
▶️ Back-to-Back Long Runs
Use the AlterG for one of the two long sessions in a “big mileage” weekend. This maintains volume without tipping into overload.
▶️ During High-Intensity Blocks
When intensity ramps up (track intervals, hill work), use the AlterG for one of your weekly medium-long runs to keep total stress in check.
▶️ Early Signs of Overuse
Noticing a sore foot, knee, or hip? Rather than skipping a session, substitute with AlterG to train through it without compounding stress.
Example Weekly Integration (for a 60–70 mile/week runner)
-
Mon: Easy run (ground)
-
Tue: Intervals (track)
-
Wed: Medium-long run on AlterG @ 75–80% BW
-
Thu: Easy run (ground)
-
Fri: Tempo run
-
Sat: Easy run on AlterG @ 70% BW
-
Sun: Long run (ground)
This plan keeps the runner’s mileage high while reducing total load exposure by 10–15%—a meaningful shift for injury prevention.
Injury Prevention Is About Consistency
For high-mileage runners, the goal isn’t just to run more—it’s to run more consistently over time. The AlterG enables this by providing a tool to train smart, reduce injury risk, and maintain fitness through both peak cycles and early warning signs.
