Objective:
This review explores how lifelong exercise in masters athletes impacts aging-related physiological systems. It focuses on:
· VO₂max and cardiovascular function
· Skeletal muscle size, function, and metabolism
· Muscle fiber adaptations
· Muscle-to-organ communication
· Implications for healthspan and aging
Key Findings:
1. VO₂max is Preserved with Lifelong Exercise
Masters athletes maintain ~50% higher VO₂max than sedentary peers, delaying decline by ~30 years and reducing disease risk.
2. Cardiovascular Health is Enhanced
Higher stroke volume, not HRmax, drives improved cardiac output. VO₂max remains high due to better heart and blood vessel function.
3. Muscle Mass and Function Decline Slower
Masters athletes maintain greater muscle size and strength, especially when training includes resistance exercise. Decline accelerates after age 70.
4. Muscle Fibers Adapt Differently
Slow-twitch fibers are preserved or improved with lifelong training. Fast-twitch fibers decline, especially in men, unless explosive training is included.
5. Lower Inflammation and Better Systemic Health
Lifelong exercise lowers systemic inflammation and supports communication between muscle and other organs, reducing disease risk.
Discussion & Implications:
· Masters athletes provide a model for healthy aging.
· Aerobic exercise preserves cardiovascular and muscle metabolic health.
· Strength and high-intensity training are needed to maintain fast-twitch function.
· Lifelong movement supports whole-body health through muscle-to-organ signaling.
Conclusion:
Lifelong exercise:
✔ Preserves VO₂max and cardiovascular health
✔ Maintains muscle size, function, and metabolism
✔ Reduces fat infiltration and inflammation
✔ Extends healthspan and functional independence
These findings show that consistent exercise across the lifespan is one of the most effective tools to delay aging and promote lifelong vitality.
