The more quality work done in these training zones, the more the body achieves the ideal stride length.Ultimately, the runner achieves the proper stride length-cadence combination that is most efficient for the physical characteristics of that runner.Because less proficient runners take fewer steps per minute, their body mass is suspended in the air for a greater amount of time which causes a greater force applied when the body makes contact with the ground.Since most injuries are impact related, cadence improvement becomes essential to the progression of the runner.Coaching Resource: The Training Model for High School Cross Country with Scott Christensen Is 180 SPM the proper cadence for your athletes at race speeds in the 5000 meter cross country race?It is probably some number in that range once the novice runner has proven to be proficient.It is thought that by running barefoot, or using very light shoes, distance runners develop a stronger toe-off upon losing contact with the ground, thus promoting a quicker cadence in their stride pattern.The well known American coach and exercise physiologist, Jack Daniels Ph D, performed experiments in his lab after the 1984 Olympics that seemed to indicate that elite distance runners run at a rate of 180 strides per minute (SPM) when competing at race pace.

A common term for stride frequency is cadence, and this word refers to the rate of leg gait cycling rotations, measured in foot placements on the ground, over a set period of time.

An easy way to reduce the metabolic cost is through step rate changes.

To spot a runner that has too much vertical movement, watch for foot landing in the gait cycle.

The most common reason for this is over-striding, which is caused by too much vertical movement in the gait cycle.

This often leads to injuries that are more common in beginners, such as sore knees.

What is important to understand is that increasing velocity definitely increases the cadence of all runners without changing stride length much at all.
