You canât make your Achilles injury-proof
But you can make sure itâs better prepared for what youâre asking it to do
When it comes to Achilles and calf training, we tend to focus on one thing:
Calf raises
Can you do 20?
25?
30?
Useful? Yes
But that tells us very little about what your calf is actually capable of
When Iâm profiling the calf, Iâm interested in three things:
1ď¸âŁ FORCE
How much force can you actually produce?
2ď¸âŁ SPEED
How quickly can you produce that force?
Because running, sprinting and changing direction donât give you 3 seconds to slowly build tension.
3ď¸âŁ CAPACITY
Can you repeatedly produce force when fatigue starts to build?
This last one is particularly important
Someone might produce a great first effort...
But what happens on rep 5?
Rep 8?
Rep 10?
Does force stay relatively stable?
Or does it fall off a cliff?
Thatâs why simply being able to do â25 calf raisesâ doesnât give me the whole picture
And none of these tests allow us to predict exactly who will rupture their Achilles
Thatâs not the point
The point is to stop guessing
Profile what the calf can currently do
Find the gaps
Build those qualities
Then prepare the athlete for the speed, force and repeated contacts their sport actually demands
You canât guarantee an Achilles wonât rupture
But you can build a better-prepared calf-Achilles complex
Donât predict
