Basketball star Tyrese Haliburton's Achilles rupture has renewed attention on a problem that affects not only elite players, but also recreational athletes. Research shows tendon injuries are most common between ages 30 and 49, and a large share are linked to sport. Yet prevention remains less discussed than treatment.
The hidden workload of tendons
Tendons are the body's connective bridges between muscle and bone. Unlike muscle, they adapt slowly and recover over longer periods. Experts note that tendon damage often builds quietly, with small declines in power, speed, and recovery appearing before pain becomes obvious.
Sports performance specialists say training should include more than jumping and sprinting. A balanced program can combine eccentric loading, force-absorption drills such as hops and jump rope, and carefully controlled explosive work. The goal is to prepare tendons for the stress of landing and deceleration, not just takeoff.
Nutrition may shape resilience
Emerging research is also linking tendon health with metabolic markers. High blood sugar can trigger changes in collagen, making tendon fibers stiffer and more fragile. In one study, athletes with elevated glucose levels faced a much higher risk of tendon injury.
Experts also point to the role of saturated fat and cholesterol in the internal environment that supports repair. At the same time, nutrients such as vitamin D, iron, zinc, manganese, and copper help collagen formation and tissue recovery. Ferritin, A1C, and vitamin D levels are among the markers sports dietitians often monitor.
The broader message is simple: tendon care is not only about rest after injury, but about building stronger tissue through smarter training and better metabolic support. As science continues to connect performance, recovery, and nutrition, prevention could become a major frontier in athlete longevity and future sports medicine.
