Among other things, technology lovers, data junkies or sports science nerds like me can follow that the cadence can be easily monitored on a GPS device. A 2016 study showed that using a commercially available watch such as a Garmin is, among other things, a reliable and valid method of tracking cadence. 1.9
The definition of the current cadence
We have known for years that many walking injuries are related to the forces that go through the body when it hits the ground with every step.
Cadence is the number of steps a person takes per minute. The reason we started paying attention is that research a few years ago has shown that this correlates with the influence of the legs with every foot strike.
Higher cadence means more steps per minute, which means less strain or impact on a run. Kind of cool, right?
Increasing the cadence can also help when crossing. Opening your crotch is a great thing for sprinting, but not efficient for distance running. For this reason, Usain Bolt does not run marathons. Most people who cross the country with their knees locked hit their heels on the ground at the point of impact.
It is a braking movement that causes a choppy step. This places a heavy strain on the joints and can lead to injuries over time. Think about how often your leg hits the ground over a 5, 10, or 15 mile run.
Change your cadence
A recent study of healthy runners running at 7.5% higher cadence for 8 weeks showed an 18-10% reduction in their stress rate (impact force) .8
These runners kept their new shape a month later. If you don't have an injury, you don't need to increase your cadence. Unless you are overwhelmed.
If you have an injury, changing your cadence can help. Studies have shown that this helps with problems such as stress fractures and lower leg injuries such as shin splints.5,8 An increased cadence has also shown an increase in the activation of the gluteal muscles.5
Making better use of these muscles during a run can help with the biomechanics associated with other injuries like IT band syndrome. 3,10
Increase your cadence
The first thing you need to do is find your cadence. Count the number of times your right foot hits the ground in 30 seconds. Multiply this by four to get the total number of footbeats per minute.
You may be thinking, "But I read on social media, or a friend told me, or a famous running magazine wrote that I should run at a cadence of 160-180. And more is better, so I shoot for 180 ! "
The media suggested a cadence of 160-180 since cadence studies were published a few years ago. In them, the participants had an average cadence of 165-185. However, I was lucky that the author presented his research results.
They are quick to notice that their results are based on increasing each runner's individual cadence by 5-10% .4.8 The mean of their subjects was 165-185, but there was great variability among all participants in the study.
If you're 140, try 147 (5%). Once you are familiar with it, try 7.5%. If you still go too far or are in pain, try 10% – and contact a PT or other sports doctor.
For all high-flyers out there, you don't have to increase your cadence above 10%. More than that will do great damage to your running economy. This is basically how much oxygen or energy you need to keep up a pace – making you run less efficiently.
The trick is to find a sweet spot for your shape that is sufficient for you not to "brake" with every step, but not so quickly that you have difficulty turning your feet over.
Use your phone to track your running
Metronome apps let you put your new, improved cadence into practice. I got good results with Run Tempo and Pro Metronome. There are other versions that can even sync your music to your tempo, which is great because who wants to hear generic pounding for 5 miles?
If you change your cadence, be patient. At first glance it will seem terribly awkward to run with a faster turnover. Use intervals first. When listening to music, start with one song “On” and two songs “Off”. Then try two one and one and increase the switch-on time from there.
Reduce your risk of injury
Recent research has focused on reducing a runner's vertical vibration or bounce.1 If you decrease this, not only will the ground reaction forces decrease, but the cadence will also decrease. So instead of counting, try to keep your body as low as possible on the floor.
Concentrate on running "softer" and not jumping. This is also traceable on some portable devices. When we talk about keeping your body on the floor, we are not talking about slumping or hanging. Keep your shoulders upright and your hips slightly bent forward.
You can also try increasing your stride from your stride. Studies have shown that the tension and load on the shins are influenced by the step size. If your posture is narrower, the lower leg is generally subjected to greater stress. 7
Do not try all of these methods at the same time. It is difficult to keep all of these changes going on for miles, and you don't know which factor actually helps. If you have a question, plan a gait analysis with a running expert to determine exactly what will help your individual needs or training.
Finally, remember to manage your training load or intensity. Your cadence or shape doesn't matter if you're constantly revising your joints and tendons. If you have racing goals, increase your mileage accordingly. There is a fine line between too much and too little.
The conclusion of the cadence
The cadence depends on how much stress or impact passes through the body when you run. If you have or have had an injury in the past, increasing your cadence may be an option for your workout.
Find your individual cadence. Not everyone should run at 165-185 steps per minute. There are other ways to reduce the impact or risk of injury, e.g. B. Increase the step size, change the training load and reduce the vertical vibration or jump.
