The Achilles Heel: From Greek Myth to Modern Reality

by Miguel dos Santos October 16, 2023

The vulnerability of the Achilles came to fame thanks to a mythological Greek hero, but unfortunately, it's an area that is still largely overlooked in the context of active lifestyles and athletics. In this comprehensive blog post, we'll explore how this legendary Achilles heel holds real importance in our modern lives, affecting more than just our feet. We'll dive deeper into the Achilles tendon's role and its far-reaching impact on our overall well-being, uncovering why a tight Achilles can lead to an array of injuries, both acute and chronic. Finally, we'll list ways to avoid suffering from a tight achilles, and introduce how Zlaant's revolutionary tools, like the ZlaantBoard, can help you keep moving pain-free.

What is the Achilles Tendon

In the realm of Greek mythology, Achilles had divine protection, but the same can't be said for our Achilles tendons. These remarkable tendons, situated at the back of your ankle, serve as the vital link between your calf muscles and heel bones. When functioning optimally, the Achilles tendon allows for seamless and efficient movement, enabling actions such as walking, running, jumping, and even standing on tiptoes. It acts as a powerful spring, storing and releasing energy with each step you take, propelling you forward and keeping you stable on your feet.

Acute Injuries: The Unexpected Domino Effect

Acute injuries, much like the unexpected arrows that struck Achilles, happen suddenly and often have a direct cause. They're characterized by their abrupt onset, usually related to a specific incident or traumatic event. An overly tight Achilles can predispose you to the following acute injuries:

Ankle Sprains: Limited ankle dorsiflexion due to Achilles tightness can impair the ankle's ability to absorb shock and adjust to uneven terrain. This may increase the likelihood of ankle sprains, which can cause pain, swelling, and instability.
Calf Strains: A tight Achilles places added stress on the calf muscles, increasing the risk of calf strains. The calf muscles may compensate for limited dorsiflexion, leading to overuse and eventual strain. This can result in calf pain and reduced mobility.
Anterior Cruciate Ligament Tears (ACL): A tight Achilles tendon limits ankle dorsiflexion, which typically results in a greater inward rotation of the lower leg. This rotation can predispose knee valgus (“Knock Knees”) and increase the knee “Q angle”, heightening the risk of ACL injuries.
Knee Ligament Tears (ACL & MCL): Reduced dorsiflexion associated with a tight Achilles can lead to an externally rotated knee. This alignment change increases the risk of MCL sprains during activities involving lateral force on the knee.

Chronic Injuries: The Slow Burn

Chronic injuries, on the other hand, are like the creeping wear and tear of a well-loved vehicle over years of use. They develop over time and often result from repetitive movements or long-term stress. A persistently tight Achilles can lead to the following issues:

Achilles Tendinopathy (Tendonitis or Tendinosis): Chronic Achilles tightness can lead to tendinopathy, which encompasses both tendonitis and tendinosis. Tendonitis involves inflammation of the Achilles tendon, often due to overuse. When not addressed, tendonitis may progress to tendinosis, characterized by degeneration of the tendon without significant inflammation. This can result in pain, stiffness, and reduced function.
Plantar Fasciitis: A tight Achilles can cause overpronation of the foot, leading to excessive stretching and stress on the plantar fascia, a band of tissue that supports the arch of the foot. Over time, this can cause chronic inflammation and heel pain.
Shin Splints: Overly tight Achilles tendons can alter the mechanics of the lower limb, leading to increased stress on the tibia. This can result in shin splints, which are characterized by pain along the front or inside of the shinbone.
PFPS (Patellofemoral Pain Syndrome, or Runner's Knee): Chronic Achilles tightness can lead to limited ankle dorsiflexion, causing overpronation and patellar maltracking. This can result in PFPS, a condition characterized by chronic knee pain, particularly around or behind the kneecap.
ITBS (Iliotibial Band Syndrome): A tight Achilles can lead to an upright posture and limited hip extension, affecting running or walking mechanics. This can result in ITBS, a condition characterized by lateral knee pain due to iliotibial band irritation.

Addressing Achilles tightness is crucial in preventing or alleviating these injuries, as some can manifest acutely during physical activity and progress into chronic issues without proper intervention.

How to Assist your Achilles

To avoid the cascade of injuries that a tight Achilles can trigger, there are a multitude of methods you can use.

Stretching for Achilles Health: Regular stretching is essential to maintain achilles flexibility. Include gentle calf and achilles stretches, either static or dynamic, in your routine to keep the tendon supple. If you are not sure how to stretch the achilles, simply incorporate the ZlaantBoard into any activity while in its “fixed position”, to ensure adequate and controlled stretching with its 21-degree incline, designed according to the ideal range of dorsiflexion.
Strengthening Exercises for Prevention: Strengthening your calf muscles and Achilles tendon can help protect against tightness. Incorporate calf raises and heel drops into your workouts. These exercises can enhance Achilles health and are easily integrated into a comprehensive fitness regimen.
Massage for Relief: Regular massage can aid in loosening tight Achilles tendons. It promotes blood circulation, reducing muscle tension and enhancing flexibility. Massage can also alleviate pain and discomfort associated with tightness. Consider using massage tools like the ZlaantBolt to target the plantar fascia, and the ZlaantShark to target the calf and achilles directly.
Footwear and Orthotics Support: Choose appropriate footwear and consider custom orthotics to maintain proper foot biomechanics. Proper arch support and cushioning can prevent undue stress on the Achilles tendon during physical activities.

A Resilient Foundation for Active Lives

The Achilles is far more than just a heel cord; it's a linchpin in your active life. Our feet are our foundation for interacting with the world, and it's crucial to ensure they function correctly. Understanding the Achilles' critical role and the cascade of injuries a tight Achilles can trigger is paramount. By incorporating stretching, strengthening, massage, and proper footwear into your routine, you can maintain Achilles health and enjoy an active, pain-free lifestyle. Zlaant offers innovative tools, such as the ZlaantBoard, to aid you in this journey. So, embrace Achilles health, protect your foundation, and keep moving confidently, free from the fear of aches and pains.
