Running Strong After 40: Managing the Hormonal Shift

Esitmated Read Time: 4 minutes

They say you don’t stop running because you get old; you get old because you stop running. But for the "Masters" athlete (40+), the rules of the game change. The training program that worked in your 20s can lead to injury and burnout in your 40s and 50s.

The Science of Aging and Endurance

As we age, our internal chemistry shifts. For men, a gradual decline in Testosterone can lead to slower muscle recovery and increased body fat. For women, Perimenopause and Menopause bring significant changes in estrogen that affect bone density and how the body uses carbohydrates for fuel.

Why Data is the "Fountain of Youth"

To keep chasing PBs into your 50s, you need to be more intentional. Monitoring your bloodwork allows you to:

  1. Track Cardiovascular Health: Even if you look fit, "Athletic Paradox" means runners can still have high cholesterol. A Lipid Profile is essential.
  2. Monitor Kidney & Liver Function: Essential for those who use anti-inflammatories (NSAIDs) to manage aches and pains.
  3. Optimize Hormones: Understanding your hormonal baseline helps you adjust your strength training and protein intake to maintain muscle mass.
