Take good look at these gals. The gal on the left (in blue) looks like she has a level pelvis, but look at the upper body. She’s leaning to the left and has a great deal of torso rotation backward. One of the clues is the abduction of her left arm. Also note how her right arm crosses across her body. We wonder how she looks in right foot stance.

The gal on the left (in red) has a subtle dip of the right side of her pelvis and also has over rotation of her upper body. Her right on crossing the body is a good reason to believe she will have a crossover gait if viewed from straight on.

While both of these gals may have adequate strength, we question how much endurance they have as well as available rotation in the hips and lumbar spine.

This is an excellent, referenced review of some of the current literature and controversy of strength and injury risk. A good read and certainly worth your time to get caught up on what’s current. We would love to see you study on endurance and injury risk.

“While muscle strength may improve tolerance of loads during running, another reason for inconsistencies in the reported relationships between strength and injury risk may be that strength is typically assessed isometrically. It’s unclear how much of an influence peak isometric strength has on the dynamic task of running, and specifically on prolonged running in the presence of muscular fatigue. Schmitz et al found that, while isometric hip strength values were similar between novice and experienced runners, hip internal rotation motion during running was higher in the novice runners, suggesting isometric strength may not correlate strongly with muscular control and kinematics during running.”

How we go about a gait assessement:
 
toes:

Take this simple test. 

Want to be faster? Better incorporate some proprioceptive training into your plan. It is the 1st part of our mantra: Skill, Endurance, and Strength (in that order). Proprioceptive training appears to be more important that strength or endurance training from an injury rehabilitation perspective as well part of an injury prevention program

 What is proprioception? It is body position awareness; ie: knowing what your limbs are doing without having to look at them.

Take this simple test:

  • Stand in a doorway with your shoes off. Keep your arms up at your sides so that you can brace yourself in case you start to fall. Lift your toes slightly so that only your foot tripod remains on the ground (ie the base of the big toe, the base of the little toe and the center of the heel.). Are you able to balance without difficulty? Good, all 3 systems (vision, vestibular and proprioceptive) are go.
  • Now close your eyes, taking away vision from the 3 systems that keep us upright in the gravitational plane. Are you able to balance for 30 seconds? If so, your vestibular and proprioceptive systems are intact.
  • Now open your eyes and look up at the ceiling. Provided you can balance without falling, now close your eyes. Extending your neck 60 degrees just took out the lateral semicircular canals of the vestibular system (see here for more info). Are you still able to balance for 30 seconds? If so, congrats; your proprioceptive system (the receptors in the joints, ligaments and muscles) is working great. If not, looks like you have some work to do. You can begin with exercises we use every day by clicking here.

Proprioception should be the 1st part of any training and/or rehabilitation program. If you don’t have a good framework to hang the rest of your training on, then you are asking for trouble.
