“…That is why researchers also investigated single sensors at specific positions on the human body which can easily and quickly be attached. Apart from placing sensors on the lower back [ 6 , 7 ], the tibia [ 8 , 9 ], or the ankle [ 10 ], a popular sensor position used in literature is the foot or the running shoe [ 2 , 11 , 12 , 13 , 14 , 15 ]. One reason for the popularity of this sensor position is the amount of different spatio-temporal parameters that can be computed.…”

Wearable sensor technology already has a great impact on the endurance running community. Smartwatches and heart rate monitors are heavily used to evaluate runners’ performance and monitor their training progress. Additionally, foot-mounted inertial measurement units (IMUs) have drawn the attention of sport scientists due to the possibility to monitor biomechanically relevant spatio-temporal parameters outside the lab in real-world environments. Researchers developed and investigated algorithms to extract various features using IMU data of different sensor positions on the foot. In this work, we evaluate whether the sensor position of IMUs mounted to running shoes has an impact on the accuracy of different spatio-temporal parameters. We compare both the raw data of the IMUs at different sensor positions as well as the accuracy of six endurance running-related parameters. We contribute a study with 29 subjects wearing running shoes equipped with four IMUs on both the left and the right shoes and a motion capture system as ground truth. The results show that the IMUs measure different raw data depending on their position on the foot and that the accuracy of the spatio-temporal parameters depends on the sensor position. We recommend to integrate IMU sensors in a cavity in the sole of a running shoe under the foot’s arch, because the raw data of this sensor position is best suitable for the reconstruction of the foot trajectory during a stride.

“…Inertial measurement units (IMUs) are one possible technology. Within sprinting research IMUs have been determined to be both accurate and reliable to determine the stance duration [8]. A single lower back mounted IMU was validated against retro-reflective motion capture (Vicon, Yarnton, Oxford, UK) and shown to reliably find angular displacement and velocity during sprinting [6].…”

“…Previous research focused on the sprint acceleration start phase and the first portion of the drive phase [2,6,8]. Whilst force plates and IMUs have been used as tools for sprint diagnosis, a correlation between the data obtained by the measurement devices has yet to be found.…”

Abstract:The transition from a stationary crouch on running-blocks to an erect running position is critical to success in sprint running. Three elite sprinters repeated five sprint starts on a 50 m-long instrumented running track each wearing three inertial measurement units (IMU) on both shanks. The IMU profiles and force plate data was highly consistent between runs. The increasing maximum ground force was correlated with the IMU data using a linear fit and gyroscope triggered acceleration component. Both techniques show promise (r 2 > 0.5). This is of significant interest to athletes and coaches using IMUs rather than a long, instrumented running track.

“…For example sensors mounted on athletic shoes (Foot Pod, Polar and Suunt), Global Positioning System (GPS) and Global Positioning System (DGPS). besides that there are also radar, photo finish, kinematic analysis, photocells and optojump (OJ) which are usually used to measure speed when running [6], [7]. All of these tools were made to diagnose, evaluate and analyze the performance of athletes for increased performance [8].…”

“…The use of the stopwatch is a problem in the accuracy of the data taken because of the time difference in the keystrokes. So that it can cause a lot of errors (human error) because the reflex rate and human sensitivity vary, so there needs to be a system of automatic timing and runner tools [7], [8].…”

The speed measuring instrument that is widely used in running activities is still a stopwatch that can only measure the time needed to travel a certain distance. Even though speed and number of steps are important components in short distance running. This study aims to produce a product design of speed monitoring and the number of steps of short distance running using an Android-based accelerometer. This study uses a qualitative approach, the main data obtained through observation, questionnaires, interviews and documentation. The procedure of research and development used is the Borg and Gall model. The results of the study show that the accelerometer on android can send data and be processed by programs that have been created by displaying information on the speed and number of steps. In conclusion, the Running Monitor product design based on android can be used to monitor the speed and number of steps of a short distance run
