Physical therapist Emmi Aguillard and other fitness experts suggest that runners must prioritize specific tendon-focused exercises to prevent common injuries. Unlike muscles, tendons require slow, heavy resistance training to adapt to the repetitive impact of running.
The 'Rope-Like' Biology of Tendon Adaptation
While most runners focus on cardiovascular endurance and muscular power, the connective tissues that link muscle to bone are often left behind.. As physical therapist Emmi Aguillard explains, tendons function as biological springs, capturing energy upon impact and releasing it during the push-off phase. This mechanism is vital for efficient movement, yet it is inherently fragile.
The biological makeup of these tissues presents a unique challenge for athletes. Tendons are structured similarly to rope—exceptionally strong but possessing significantly less blood supply than muscle tissue. Because recovery and strengthening are heavily dependent on blood flow, tendons adapt to training stimuli much more slowly than the cardiovsacular system or skeletal muscles. This discrepancy creates a dangerous wiindow for injury, particularly when runners implement rapid increases in mileage or intensity that outpace the tendon's ability to strengthen.
The 80% One-Rep Max Protocol
To bridge the gap between muscle strength and tendon resilience, experts recommend a specific method of resistance training. According to the report, the most effective way to fortify these tissues is through slow, heavy lifting. This involves performing movements with a load equivalent to 80 percent of an individual's one-rep max, utilizing a controlled tempo of three seconds for both the lifting and lowering phases.
The efficacy of this approach is supported by scientific literature. The report highlights a review of 27 different studies involving more than 260 participants, which concluded that heavy weightlifting is the premier method for increasing tendon strength. For runners without existing pain, the recommended frequency is two to three days of this heavy strength training per week.
Targeting the Achilles, Patellar, and Hamstring Tendons
Effective tendon training requires a targeted approach to the specific areas most vulnerable to running loads. The Achilles tendon, which connects the calf to the heel, can be strengthened through standing calf raises on an incline. For the hamstring tendons, which manage leg control during the swing phase, experts suggest using deadlifts with a barbell, hex bar, or heavy dumbbells.
Beyond these bilateral movements, unilateral exercises like split squats are recommended to build stability and strength. these exercises should be performed with a slow, three-second cadence to ensure the load is being applied to the tendons rather than just the muscles. By addressing the Achilles, patellar, and hamstring tendons specifically, runners can build a more resilient foundation for high-impact activity.
Gaps in the 11-Participant Plyometric Evidence
While the report suggests that plyometric exercises—fast, explosive movements—are beneficial for runners, the evidence provided is limited. The source cites a small study of only 11 participants to support the use of plyometrics for tendon health. This small sample size leaves several questions unanswered: specifically, whether these explosive movements are safe for runners with varying levels of existing tendon stiffness, and how they should be integrated into a training cycle without causing overuse injuries. Furthermore, the report does not specify how a runner should balance these explosive sessions with high-intensity running days.
