Display VideosThese video clips were used in assessing your running form. The assessment of each video is included with the clip.
|Side View Feet|
|From this angle we examine stride count, foot contact duration, foot strike, and knee angle.|
Stride Count: Your stride count is currently 89. The optimal running cadence is
88 - 90 steps per minute.
speed = stride count x stride length
Foot Contact Duration: In examining the video, your foot maintains contact with the ground for 7 frames. This translates to aproximately 0.23 seconds. The duration that your foot is on the ground seems to be appropriate. This decreases your chances for early muscle fatigue and muscle overuse injury.
Foot Strike: You make initial contact with your heel when landing. This is appropriate for your current running form.
Knee Angle: When your foot hits the ground you have the appropriate amount of bend in your knees. This enables your legs to better absorb the ground reaction forces.
|Rear View Feet|
|From this angle we examine shoe/orthotic suitability, foot strike, angle of heel on landing, angle of foot leaving the ground, and leg backswing.|
Video analysis of your current neutral shoe shows that you are not wearing the most suitable running shoe to match your biomechanics.
Foot Strike: You are running with both feet straight. This is the most efficient position for your feet. You have decreased chances of certain overuse injuries and you have increased potential to improve your stride strength performance.
Heel Angle: Both heels are contacting the ground at the same angle to the ground. This shows good symmetry between both legs.
Foot Angle Leaving Ground: Your right foot is leaving the ground or you are coming off your toes excessively to the outside. This is a good sign that you don't have the appropriate shoe and/or orthotic compliment to correct the asymmetry between your left and right foot or you may be experiencing a biomechanical imbalance between you left and right leg.
Leg Back Swing: The backswing of your legs follow the same motion showing good biomechanical symmetry.
|Full Side View|
|From this angle we examine bounce, stride length, shoulder position, arm swing, hand position, and posture.|
A bouncing stride can cause an increased incidence of stress related injuries because
of the increased impact from your bodies momentum against the ground reaction force.
Stride Length: You don't appear to be overstriding. You display a very efficient stride length. This will help prevent overuse injuries.
Shoulders: You have an apparent difference between your left and right shoulder rotation with your right shoulder moving forward more than your left when swinging your arms. Asymmetry between your shoulders is a good sign of an imbalance in you upperbody and/or hips. I would suggest to start working on slightly pushing your right elbow back when running.
Arm Swing: Your armswing tends to be straight forward and backward which will ultimately aid in better body alignment and improved efficiency.
Hand Position: You appear to hold your hands between your waistline and chest. This is the optimal position and will improve your running efficiency and diminish the occurance of muscle imbalances.
Posture: You appear to run with an appropriate running posture. Having relaxed shoulders and maintaining your chest high with a straight back diminish the occurance of muscle imbalances and improves breathing efficiency.
