Running Gait and injury

Here is a study which looked at treating a common running injury - Chronic exertional compartment syndrome (CECS) - by getting runners to modify their running technique, moving to a forefoot strike.   Although there were only 2 in the study it seemed to fix the injury.  The entire paper is here.

Here is the abstract for you.

EFFECTS OF FOREFOOT RUNNING ON CHRONIC EXERTIONAL COMPARTMENT SYNDROME: A CASE SERIES.

INTRODUCTION:
Chronic exertional compartment syndrome (CECS) is a condition that occurs almost exclusively with running whereby exercise increases intramuscular pressure compromising circulation, prohibiting muscular function, and causing pain in the lower leg. Currently, a lack of evidence exists for the effective conservative management of CECS. Altering running mechanics by adopting forefoot running as opposed to heel striking may assist in the treatment of CECS, specifically with anterior compartment symptoms.
CASE DESCRIPTION:
The purpose of this case series is to describe the outcomes for subjects with CECS through a systematic conservative treatment model focused on forefoot running. Subject one was a 21 y/o female with a 4 year history of CECS and subject two was a 21 y/o male, 7 months status-post two-compartment right leg fasciotomy with a return of symptoms and a new onset of symptoms on the contralateral side.
OUTCOME:
Both subjects modified their running technique over a period of six weeks. Kinematic and kinetic analysis revealed increased step rate while step length, impulse, and peak vertical ground reaction forces decreased. In addition, leg intracompartmental pressures decreased from pre-training to post-training. Within 6 weeks of intervention subjects increased their running distance and speed absent of symptoms of CECS. Follow-up questionnaires were completed by the subjects at 7 months following intervention; subject one reported running distances up to 12.87 km pain-free and subject two reported running 6.44 km pain-free consistently 3 times a week.
DISCUSSION:
This case series describes a potentially beneficial conservative management approach to CECS in the form of forefoot running instruction. Further research in this area is warranted to further explore the benefits of adopting a forefoot running technique for CECS as well as other musculoskeletal overuse complaints.

Captain Barclay's Gait

I was reading recently about the amazing Captain Barclay.  His most famous exploit was the walking of 1,000 miles (1,600 km) in 1000 hours for 1000 guineas in 1809.  There is good analysis here.

I thought that the way in which his gait was described was interesting.  It is essentially POSE walking.

Walter Thom attributes Captain Barclay's pedestrian powers to his great strength and his walking style that involved bending the body forward to throw the weight on the knees, taking short steps and raising his feet only a few inches from the ground. (from here)

When walking, the Captain took comparatively short steps and had an air of leaning more than slightly forward. (from this book)
