12 major running metrics for peak performance

Based on running dynamics analysis technology, we provide 12 running metrics for real-time foot tracking to help runners assess their running form, reduce the risk of injury, and improve running efficiency.

  • Duration

  • Steps (steps)

  • Distance (km)

  • pace (min'sec

  • Cadence (steps/min, spm)

  • Stride (cm)

  • Ground contact time (GCT, ms)

  • Flight time (ms)

  • Stance time to flight time ratio

  • Eversion (degree)

  • Foot strike patern (%)

  • Landing Impact (BW)

Duration

The duration of time between the user turning on and ending the exercise mode.

Steps (steps)

The cumulative number of times the user moved his feet alternately during the exercise period.

Distance (km)

The total distance (km) accumulated by the user during the exercise.

pace (min'sec

It reflects how fast or slow the user walks or runs and how long it takes to complete a given distance (m's''/km).

Cadence (steps/min, spm)

The number of steps per minute (in steps/minute) that a user takes when walking or running.

Suggestions

Cadence and stride length together determine the speed of the pace.

At the same speed, a higher stride length will reduce the running efficiency (i.e. produce a higher free height touchdown point) and make the user prone to shift the centre of gravity during training, resulting in a more pronounced braking effect and increasing the risk of knee and tibialis anterior muscle injuries.

Therefore, under a certain pace, we recommended to adopt a faster pace instead of a higher stride length. Beginners should also give priority to improving the cadence to increase the pace rather than boosting the stride, in order to reduce the injury and improve performance.

Stride (cm)

The length of each stride the user takes when walking or running, i.e. the distance between the centers of the feet (cm).

Suggestions

Cadence and stride length together determine the speed of the pace.

At the same speed, a higher stride length will reduce the running efficiency (i.e. produce a higher free height touchdown point) and make the user prone to shift the centre of gravity during training, resulting in a more pronounced braking effect and increasing the risk of knee and tibialis anterior muscle injuries.

Therefore, under a certain pace, we recommended to adopt a faster pace instead of a higher stride length. Beginners should also give priority to improving the cadence to increase the pace rather than boosting the stride, in order to reduce the injury and improve performance.

Ground contact time (GCT, ms)

The average duration of time between landing and leaving the ground with one foot when the user is running.

Ground contact time is related to speed, cadence, and running efficiency, the shorter the ground contact time represents the high efficiency of muscle elastic energy conversion, the higher the running efficiency. Generally, the elite runners usually have a ground contact time of 220 milliseconds or less.

Suggestions

Adjust the running postures

During running, please pay attention to whether you have problems such as heel landing first, straddle running and pushing stirrups, and consciously use your forefoot on the ground and speed up the cadence to adjust the running posture, improving training effect.

Improving bounce jump

Users can make postural adjustments during jumping exercises and quickly confirm progress by reviewing ground contact times

1.User can practice jumping for 1 minute, 3-5 sets in total (knees slightly bent, do not straighten your knees when jumping up) before every training session. When you proficient at this, you can choose single-leg jumping or other advanced courses.

2. User can improve the sense of balance by doing a toe touch jump during training.

3. User can add A-Skip and B-Skip drills during training.

Flight time (ms)

It refers to the time neither foot is in contact with the ground between consecutive steps of the left to the right foot or vice versa.The flight time of excellent runners is generally greater than 125 milliseconds.

Suggestions

Users can extent the flight time (i.e., shorten the ground contact time) and improve the efficiency of converting the muscle elastic energy by doing exercises such as lunge jumps, deep squat jumps, and continuous single-leg jump.

Stance time to flight time ratio

Ground contact time/flight time. Under the same cadence, a smaller stance time to flight time ratio indicates better running skills, and there is more time spend in the air. (with no ground contact)

The lighter and smoother the running posture, the more efficient the running. In general, the stance time to flight time ratio of elite marathon runners is about 1.0, elite sprinters about 0.5, and ordinary runners about 2.0.

Suggestions

Ways to reduce the stance time to flight time ratio

1. Increase flight time

Strengthening the runner's forward-leaning upward pulling technique training can improve the stride length, increase the stance time to flight time ratio, reduce stance time to flight time ratio and further improve the running efficiency.

2. Reduce ground contact time

It is more effective and easier to do for ordinary runners. See the advice on how to reduce ground contact time.

Eversion (degree)

The eversion degree refers to the angle at which the ankle rotates inward from the initial landing to the start of the stirrups when the user is running. with the help of foot eversion, users can cushion ground forces and reduce the vibration.

The normal range of ankle rotation is usually between 5° and 25°. If the angle of foot rotation is too small (less than 5°), the muscle cushioning will be weakened, which will easily lead to plantar pain, calf pain, knee injuries, or other problems.

On the other hand, if the angle of pronation is too large (greater than 25°), it can lead to ankle ligament strains. Studies have found that running injuries occur least when the eversion angle is between 7-10 degrees.

Suggestions

1.When the foot eversion degree is too small, runners can choose cushioned sports shoes for protection and correction, while reducing running training and jumping movements on uneven surfaces to protect the joints.

2.When the foot eversion degree is too large, runners can enhance ankle stability through targeted training, such as ankle rotation exercises and heel lift stances. You can also practice toe up hooks, downward tensing, varus of the foot, and eversion of the foot with the help of elastic bands.

Foot strike patern (%)

The user walks or runs with a single-foot landing to contact the ground instantly.

There are three main foot strike patterns: forefoot landing, full-foot landing, and heel landing.

Forefoot landing
It means landing on the forefoot firstly, followed by the heel, to keep the weight of the body on the forefoot when users are running. This method is suitable for elite runners such as sprinters, long-distance runners.

Full-foot landing
It is a landing way that between the forefoot and the heel landing. The full-foot landing is not the entire foot landing at the same time, but actually the outside of the foot lands first, and quickly transitions to the inside of the full-foot landing.

Heel landing
It means the heel first lands on the ground and then transition to the forefoot, completing a gait cycle by internally rotating and stomping the ground during running,. Although heel landings have a high landing impact on the knee joint, most runners are used to landing on their heels. The user can adopt special training to improve it.


Suggestions

There are slightly differences in running posture because of the different running habits. Runners can improve their leg muscle strength and adjust to the target foot strike pattern by choosing different training methods such as marching in place, variable pace running, running uphill, jumping rope, deep squat jumping according to individual physical condition and running level. In addition, runners can reduce the landing impact by choosing shoes with better cushioning.

Landing Impact (BW)

It refers to the maximum value of the ground reaction force on the pelma when the user touches the ground during running.

The better the cushioning technology, the smaller the landing impact; Meanwhile, running pace and landing impact usually show a positive correlation, the faster the speed, the greater the landing impact. The unit of landing impact is usually expressed as a multiple of body weight (BW, Body Weight). For example, 2.5BW means that the maximum value of ground reaction force on the pelma is 2.5 times of body weight during the running process.

Suggestions

How to cushion the force and reduce the landing impact

1.Improve running posture and adopt scientific and reasonable running skills: when landing, the knee joint can be kept moderately bent, which is conducive to the cushioning of the skeleton; at the same speed, increase the cadence and reduce the flight time, which can save energy and achieve the cushioning effect.

2.Strengthen muscle strength: good muscle strength can provide enough power and also can fully cushion the force.

3.Improve the body's ability to withstand step by step : the body's ability to withstand needs to be gradually adapted and improved. Cooperating with professional and scientific running skills can reduce the loss beyond its ability, to achieve excellent running effect.

4.Give the body recovery and repair time: excessive exercise is prone to the consumption of the body, if the body is not given enough repair and recovery time, it is easy to cause the body to overdraft and exhaustion, therefore, it is necessary to give the body recovery and repair time in time.
