When we exercise, all the tissue in our bodies tendons, muscles, bones etc. This is normal and part of the process of how exercise makes us stronger — it acts as the signal to the brain to strengthen that part of the body. Depending on how fit you are and the intensity of the training session, it can take anything between 24 and 72 hours for your body to fully repair this micro-damage. If you do another hard training session before your body has fully repaired, the micro-damage accumulates and eventually cause overuse injuries like tendonitis.
They move away from each other and become disorganised. This causes that part of the tendon to lose some of its strength which means that it may not be strong enough to cope with your normal activities. Relative rest means that you have to reduce your activities to a level that does not cause your tendon to hurt. In fact, complete rest may even make it lose more strength. The treatment plans in the Exakt Health app provide specific guidance on how you can decide what activities are OK to continue.
Strength training exercises can help to restore the strength in your injured tendon, but it has to be pitched at the right level for your injury. A typical training plan for a tendonitis will start with easy, low load exercises and progress over time to include high load and explosive movements.

This will depend on how long you wait before you start with the correct treatment plan as well as how strong your tendon and calf is at that point.
Tendons are very slow to heal. It takes much longer to produce and strengthen collagen fibres than muscle fibres. The term tendon tear is pretty self-explanatory. You can get partial tears where just some of the collagen fibres are torn and full ruptures where the tendon is fully torn through. In order for the tear to heal, the two ends have to grow back together.
The treatment for a full tendon rupture may include surgery if the ends of the tendon have separated far apart. In some cases, where the tendon ends have not moved that far, they can grow back together if your injured body part is immobilized for several weeks.
This depends on the extent of the tear and can take anything from 6 to 18 months to regain full strength. Getting the correct treatment as soon as possible is the most important thing. There is also some research that suggests that taking a collagen supplement in combination with a low dose of vitamin C before you do your exercises, may also help the tendon repair more quickly. We understand. Finding convenient and reliable help for injuries online can be a tedious and demoralising process.
The Exakt Health App provides a convenient, intuitive and science-based injury rehab experience for runners. Ligaments hold bone to bone together, and tendons hold bone to muscle, so they have to be very strong tissue. Muscles are only meant to contract, not hold things together, and they require a lot of oxygen in order to contract over and over again.
To supply this oxygen, they have a very good blood supply. In order to have a good blood supply, there has to be a lot of blood vessels within the tissue. The blood vessels that travel through the muscles are very spongy and therefore make the muscle tissue somewhat spongy, which is what makes them susceptible to injury, but they need the good blood supply to perform properly. The excellent blood supply is also what allows them to heal very quickly when they are injured, and that is why strained muscle tend to feel better even after a week or so, depending on the severity of the injury or strain.
Tendons and ligaments have a very poor blood supply meaning that they do not have any blood vessels that travel through them, which is what makes them very strong and resistant to stretch. This is also why the do not heal quickly, because they lack a direct blood supply.
Now some of you may be asking, then how do they get what they need to heal. The materials that they need to heal are supplied to the body in the blood, and then are transferred to the tissue thru the fluid that leaves the blood flow carrying the needed materials.
The stages of tendon healing takes time but occurs in 3 stages. A repaired tendon is weakest from days post-op. The tendon strength increases moderately by days post-op and max strength is reached at 6 months post-op.
Early mobilization allows for improved range of motion ROM , but can decrease the strength of the tendon repair. This is why undergoing Occupational or Physical Therapy treatment is an important part of tendon healing.
If an individual progresses too quickly past post-surgical guidelines the tendon healing process can be impaired. One of the biggest concerns with tendon healing is increased scarring which prevents movement, loss of joint mobility, stiffness and possible tendon re-injury.
The tendon healing process lasts 12 weeks pending injury. They hypothesize that each individual tissue with regenerative abilities within the mouse model—including tendon tissue—has the ability to regenerate regardless of the systemic environment. To investigate this, they have initiated a series of projects. In one, they have organ-cultured MRL tendons in the lab to see how the tendons filled missing sections.
In another project, Andarawis-Puri and her colleagues are swapping injured tendons between regular healer and MRL mice models to see how the tendons heal when they are in the different systemic environments. In yet another, they are seeding cells from the tendons of normal healer mice models onto decellularized tendons from MRL mice models to see if the tendon matrix from the MRL tendon can reprogram the cells from the normal healer and prompt them to lay down matrix in a regenerative manner.
If so, this may be a key step to advancing tissue engineering approaches for humans. It would be great if we could just inject something—say, a cocktail of growth factors—that would actually tell your cells how to lay down good matrix to ultimately produce scarless healing.
