(And What to Do About It)?
Running is a high-impact sport admired for its simplicity, but beneath the surface, it places substantial stress on your knees, hips, and muscles. Whether you're training for a marathon or jogging daily, the repetitive motion over time can lead to knee cartilage wear, inflammation, and chronic muscle fatigue — especially if your protein intake or recovery nutrition is lacking.
Many runners begin to feel unexplained joint aches, stiffness after long runs, or even reduced performance in their 30s or 40s — without realizing they may be under-fueling their muscles and neglecting recovery.

Common issues runners face include:
Early signs of runner’s knee (patellofemoral pain syndrome)
Micro-tears in muscle fibers without proper repair
Loss of lean muscle mass due to inadequate protein intake
Increased joint friction due to cartilage thinning
Without proper intervention, these can lead to long-term mobility issues or even force runners to give up the sport entirely.

Here’s where strategic nutrition and muscle care come into play. One key area most runners overlook? Protein.After endurance workouts, your body needs high-quality protein to rebuild muscle fibers and nutrients like calcium, magnesium, and vitamin D to support joint and bone health.
Alongside protein, HMB (β-Hydroxy β-Methylbutyrate) plays a unique role in reducing muscle breakdown. It’s especially valuable for endurance athletes over 30, when muscle preservation becomes more challenging.
Start tracking:
Post-run muscle soreness and how long it lasts
Your average daily protein intake (g/day)
Any signs of joint pain, stiffness, or “grinding” sensation in the knees
Recovery time between runs
Notice trends in fatigue or discomfort? Your body may be undernourished, even if you eat regularly.
💡 Here are 5 evidence-based tips for runners to reduce injury risk and protect long-term mobility:
Prioritize Post-Run Nutrition
Within 30–60 minutes post-run, consume a protein-rich shake or meal. This is when your body is most receptive to repair nutrients.
Strength Training Twice Weekly
Add light resistance work for glutes, quads, hamstrings, and calves to improve joint stability and reduce injury risk.
Stay Ahead of Inflammation
Include omega-3-rich foods or supplements and magnesium to manage exercise-induced inflammation.
Track Shoe Wear and Running Surface
Worn-out shoes or hard surfaces increase knee stress. Replace shoes every 500–800 km.
Supplement Smartly
Use targeted nutrition support with HMB, collagen (UC-II®), protein, and micronutrients that aid both muscle recovery and joint lubrication.
