When Karin Grävare Silbernagel was learning to develop into a bodily therapist, she remembers hardly studying about tendons. “The tendon was type of thought of this inert construction that simply linked the muscle to the bone,” she says.
Although she shortly realized when she began her medical follow over 30 years in the past how large of an issue an injured tendon could possibly be. Increasingly more sufferers got here in complaining of ache, affected by tendonitis and different tendon points.
Now Grävare Silbernagel is the principal investigator on the Tendon and Ligament Analysis Staff on the College of Delaware.
And any runner who has ever handled tendon points is aware of, too, the time and power it takes to come back again. Fortunate for us, tendons and the way they are often optimized for athletic efficiency are being studied and talked about greater than ever earlier than.
Take this recent research printed in Science Translational Medication. Evaluating mice to males, the researchers discovered that tendons that reply to mechanical stress can enhance operating and leaping skills over muscle tissue, within the case of 1 particular ion channel expression (Piezo 1). In mice with Piezo 1, tendons appeared to retailer extra elastic power.
“Tendons have been in a position to stretch extra simply and retailer bigger quantities of power, which allowed for larger flexion and larger instantaneous energy produced by the ankle, whether or not alterations have been innate or launched after mice matured,” mentioned senior writer Hiroshi Asahara in a press launch. “Muscle-specific alterations, nevertheless, didn’t lead to improved bodily efficiency.”
And whereas the ion expression is reliant on genetics, the analysis nonetheless reveals how important tendons are to operating efficiency in a sport that usually overlooks prehab, cross-training, and different actions helpful to tendon well being.
Finally the researchers hope their findings can someday result in new remedies for tendon-related issues.
What Do Tendons Do Precisely?
It’s nice that extra analysis is rising, however what are you alleged to do with that info? First let’s dig into what tendons are and the function they play in your physique whereas operating.
It may be simple to confuse tendons and ligaments and their function within the musculoskeletal system. They’re very comparable in make-up–each being fibrous connective tissue–however ligaments be a part of bone to bone, whereas tendons connect muscle to bone. Tendons assist to propel the drive generated by your muscle tissue to maneuver your muscle tissue, and thus get your physique in movement.
Although runners are effectively acquainted with the Achilles tendon because it lands within the prime 5 most typical accidents amongst runners, accidents of the patellar tendon (connects your knee cap to your shin bone), tibialis posterior tendon (attaching muscle tissue on the again of your calf to your foot), and gluteal tendons (a typical explanation for hip ache) are additionally comparatively widespread.
And sure, your tendons make a distinction in your efficiency as a runner. Genetically talking, individuals with longer Achilles tendons are in a position to run extra effectively in line with a examine printed within the journal Medicine & Science in Sports and Exercise. That’s as a result of as your foot strikes the bottom, the Achilles tendon stretches. The longer that stretch, the extra power may be returned when your foot then pushes off. That energetic drive is mixed with power created by contracting muscle tissue, which is why the 2 physique elements are sometimes called the muscle-tendon complicated or unit.

The right way to Adapt Your Tendons for Healthful Working
It’s unclear precisely how a lot of the tendons’ effectivity is because of genetics versus dietary and physiological interventions. However what’s turning into more and more clear is which you can really train your tendons to a minimum of a point. Bodily exercise promotes collagen turnover. And collagen makes up 80 p.c of the dry weight of tendons.
Although individuals typically complain about tightness, you do need your tendons to keep up a sure degree of stiffness to get their job performed. Grävare Silbernagel compares it to a basketball. “You probably have a basketball, however don’t have sufficient air in it, you want a number of power to bounce it. However when you’ve got the right quantity of air, it will possibly bounce again.”
On the opposite finish of the spectrum although, tendons which can be too stiff can develop into brittle and prone to harm, which is why a Goldilocks state of affairs is what it’s best to goal for. Tight, however not too tight.

And that tightness varies even for the kind of tendon and its principal operate. Typically talking, you need your Achilles tendon to be on the stiffer facet with a view to produce extra drive, for instance. The tendons that connect to your hip flexors, nevertheless, must be extra compliant (i.e. stretchier) for a wider vary of movement.

Power Prepare These Tender Tendons
Tendons, like muscle, reply to load-bearing workouts. Power coaching for tendon well being is one thing Grävare Silbernagel consults on with professional athletes, and has develop into a brand new sizzling matter within the final 10-15 years.
Grävare Silbernagel recommends heavy weight coaching to maintain tendons wholesome. “ research from power coaching, in the event you do 50 p.c of max voluntary contraction versus 90 [percent], the tendon responds by getting larger and stronger when you’ve got a bit of little bit of a heavier load. And that load, you type of pressure it to really stretch the tendon is type of what you could do,” she says.
Precisely how a lot load you could practice your tendons to stop harm and likewise rehab harm, she doesn’t know, nevertheless it’s one thing she’s looking for out. She calls it the holy grail.
Some coaches additionally advocate runners introduce mobility and plyometric workouts into their routine to fight hysteresis–a time period used to consult with power misplaced between the stretch and launch of the tendon. Separate from the stiffness of the tendon, decreasing hysteresis minimizes power loss.
Specialists additionally advocate comparable load-bearing and plyometric workouts that may forestall harm within the rehab of the particular harm itself in nearly a cyclical style. “After recovering from a tendon harm, doing an identical train program to keep up tendon well being is suggested to cut back threat for future harm/re-injury,” says Dr. Adam Tenforde, a former aggressive runner and sports activities drugs doctor on the Spaulding Nationwide Working Heart.
Dietary Issues
Like constructing bone power, tendons adapt to exercise over time and are supported by correct vitamin and hydration, says Dr. Tenforde.
“Vitamin and hydration are necessary to assist guarantee applicable elements of collagen (protein) and caloric consumption meets demand of sports activities to help general well being and being in a internet constructive power state,” he says.
Like talked about earlier than, collagen is a serious part for the construction of the tendon and will due to this fact be a consideration in a well-rounded sport-focused weight-reduction plan. There’s no scarcity of collagen-laden meals dietary supplements today, however there are additionally ways to eat that help your body better produce collagen naturally. Collagen turns into more durable to your physique to provide as you age, so it’s particularly necessary for masters runners to think about this structurally necessary protein.
Extra to Be taught
Together with the ‘holy grail’ of tendon-loading, Grävare Silbernagel additionally desires to be taught extra about how tendons adapt otherwise in girls than in males–as a result of they do. Research shows that ladies have a decrease price of tendon collagen synthesis following train than males, much less mechanical power of their tendons, and are additionally extra prone to maintain a smooth tissue harm from bodily exercise.
With out extra info on sex-specific variations, feminine athletes received’t have the identical honest probability to make absolutely the most of those energy-giving propulsion mechanisms we name tendons.
