In episode 388 of The Physical Performance Show, we're syndicating a conversation from the Physio Network platform's Physio Discussed podcast. Our own Brad Beer, Sports and Exercise Physiotherapist and Principal Physiotherapist at Pogo Physio, joins Dr. Brady Green, physiotherapist and researcher, and host Sarah Yule for a deep dive into calf muscle strain injuries.
Brad and Brady explore where research and clinical practice meet: how to profile physical capacity after a calf strain, what strength and reactive qualities need restoring before running, how to make return-to-run decisions, and how much attention footwear and imaging deserve. Brad brings the view from the clinical coalface, and Brady brings the latest research from high-performance sport.
A special thanks to the Physio Network platform for their generosity and collegiality in sharing this episode.

IN THIS EPISODE YOU'LL HEAR:
- What we understand better about calf strains than we did 5 to 10 years ago, including pathology, return-to-play timeframes, recurrence susceptibility and physical capacity profiling
- How the soleus vs gastrocnemius distinction has changed return-to-run prescription, including avoiding plodding on return to a soleus-based running program
- Why modifiable factors like strength, force production and stretch-shortening cycle proficiency matter alongside non-modifiable risk factors like age and prior calf strain history
- Brad's top three clinical mistakes: not clearly establishing the mechanism and training load context, progressing too quickly, and not impressing on athletes the need for ongoing preventative loading
- Why recurrence risk stays elevated long after return to play, and why preventative loading and load management may need to continue for the rest of the season
- Longitudinal AFL data showing athletes can build soleus strength from pre-season to early competition and maintain it through the season, and why a decline in strength is a flag to act on
- Why profiling the individual matters: a strong athlete may have strained their calf because of a stiffness deficiency or load management issue rather than weakness
- Brad's three-legged stool framework: repeated force (endurance), peak force, and reactive strength/plyometric qualities
- How to differentiate a gastrocnemius from a soleus strain using mechanism of onset, and why gradual, non-specific onset injuries are less likely to involve significant connective tissue disruption
- The clinical assessment toolkit: observation, progressive loading tests, RPE, palpation, pain on contraction and stretch, and differential diagnosis (bone stress, deep flexors, plantaris)
- Quality markers during calf testing, including eccentric control, long toe flexor clawing, rep counts and visible shakiness
- Home-based repeated force exercises such as single-leg calf raises, stair walking and pulsing, plus cueing tips like using a metronome and watching line of force through the foot
- Progressing from vertical to horizontal force production, including sled and Prowler pushes, step and box drills
- Return-to-run criteria: symptom resolution, performance readiness, 20+ slow calf raises, and 20 to 30 single-leg pogo hops with symmetrical quality
- Why holding your nerve for a few extra sessions at the end of rehab rarely costs you time, but rushing can
- Objective metrics with force plates: sub-maximal and maximal isometric testing, testing in dorsiflexion, rate of force development, reactive strength index, and pulsing to fatigue
- Footwear: Brad and Brady's "don't overcomplicate it, but be aware" approach, covering shoe drop, stiffness, rocker soles and stack height
- What imaging can and can't tell us, and Brady's top-down decision-making framework from index vs recurrent injury through to aponeurosis involvement
- The one thing each guest wants clinicians to do differently tomorrow
QUOTES / TAKEAWAYS:
"Do things well, not just at the level."
"We don't need to overcomplicate it, but we do need to be aware."
"The calf isn't always the culprit."
"It's often the hardest thing is to make the complex simple."
"You're not necessarily going to lose out if you hold your nerve for a few days or several sessions."
"What is the property that we're reconditioning? What is the stimulus that we're trying to apply?"
