“Summary/conclusion: Increasing age and previous calf strain injury are the most predictive of future calf injury. The overall paucity of evidence and the trend for studies of a high risk of bias show that further research needs to be undertaken.”
The conclusion of this SR is typical for many MSK injuries. And it isn’t great because increasing age and previous calf strain injury are both non-modifiable risk factors.
It is surprising that there is such a lack of evidence for calf strain injury risk factors. Only 10 studies were included in this SR.
Strength is a common risk factor for many muscle strain injuries eg. hamstring, quad. But there is no such evidence for calf strain injuries so far. However from what we have learned from hamstring strain injury risk factors, none of the modifiable risk factors are strong risk factors on their own and are not able to predict who will go on to develop a hamstring strain injury due to large overlaps.
Clearly more research is needed in this area and also in the area of understanding risk factors in general.
