Hamstring injuries: prevention and treatment – an update

This paper on the BJSM, Hamstring injuries: prevention and treatment—an update, is a must read for anyone who deals with athletes or are susceptible to hamstring tears

“Despite increased knowledge of hamstring muscle injuries, the incidence has not diminished. We now know that not all hamstring injuries are the same and that certain types of injuries require prolonged rehabilitation and return to play. The slow stretch type of injury and injuries involving the central tendon both require longer times to return to play. A number of factors have been proposed as being indicators of time taken to return to play, but the evidence for these is conflicting. Recurrence rates remain high and it is now thought that strength deficits may be an important factor. Strengthening exercise should be performed with the hamstrings in a lengthened position. There is conflicting evidence regarding the efficacy of platelet-rich plasma injection in the treatment of hamstring injuries so at this stage we cannot advise their use. Various tests have been proposed as predictors of hamstring injury and the use of the Nordboard is an interesting addition to the testing process. Prevention of these injuries is the ultimate aim and there is increasing evidence that Nordic hamstring exercises are effective in reducing the incidence.  “

Running to much is dangerous. Really?

There have been a few stories out this week with titles such as “Fast running is as deadly as sitting on a couch, scientists find” , “Stop binge jogging” , “Too much jogging ‘as bad as none at all'”  after  an article was published in the Journal of the American College Cardiology about the Copenhagen City Heart Study. The study found that light to moderate running was associated with living longer in comparison to being sedentary but running more often/strenuously did not. There were some serious limitations in the study as pointed out in this article about the reactionary press response on the NHS website and that Alex at Sweat Science , who is always worth a read, point out.

How does your brain respond to pain?

This is a great little video that explains that though we all experience pain we all experience pain differently. Put together by Karen D. Davis, PhD.

Aerobic exercise training increases pain tolerance

The study talks about exercising 3x a week for 30 minutes in healthy individuals. If we are talking about those suffering from chronic pain we might want to increase the frequency but decrease the length of time. Even going for a very short walk of 5 minutes at a time can make a significant impact. From there we can increase the number per day and then perhaps the number of times per day but the bottom line is that easy effort aerobic exercise is good for dealing with pain.
