Why Injured Runners Should Replace their ‘Lost Running Time’

Running-related injuries (RRIs) are frequent amongst the running population. The annual rate of running-related injuries ranges from 24 to 65%, with the most commonly injured joint being the knee (van Gent et al. 2007). Among runners training for a marathon, the injury rate has been reported as high as 90% (Franke et al. 2019).  The majority (around 80%) of running injuries are due to overuse with no clear traumatic event.

 

Physical Activity Behavior of Runners during Period of Injury

As many runners get injured, it is common that runners are unable to run during this period or while recovering from injury or during rehab.
So, do runners involve in other training methods like cycling or swimming to maintain their fitness, during this period? A recent study by Davis et al. (2020) has shown that it is not the case.

 

This study looked at 49 recreational runners and followed them for a year. All the runners were issued activity monitors to track their daily activity levels and they also completed a weekly survey about pain and training levels.  In this study, the definition of running injury was the inability to train for at least three sessions within a week.


Compared with uninjured weeks, runners engaged in few minutes of moderate to vigorous activity per day if they had an injury. Based on the results of this study, it seems that runners don’t replace lost running time with other exercises to maintain their fitness levels.

 

 

Key Take-away from this Study

As therapists, it is important that we are aware of the physical activity behavior of the injured runners, during the period that they are unable to run. It seems that runners are reluctant to engage in other forms of training when they are not running.

It is important that we encourage runners to maintain their cardiovascular fitness with plenty of low-impact ways to cross-train (e.g., Swimming, cycling, bodyweight routines) and keep them moving, instead of being sedentary. 

Being active comes with a lot of physical and mental benefits and can be beneficial to the injured runner when they are feeling down with the injury. A rest-only approach is not beneficial and regular involvement in cross-training will enable the runners to get back to pre-injury levels and an early return to running.
