“…Axial peak accelerations measured by the distal IMU accelerometer ( a IMU z ) were slightly higher compared with the proximal IMU accelerometer on a group level; however, there was no significant difference found between both IMU locations over all speeds (Table 1). This indicates that it did not matter here where the IMU was attached, but this is in contrast with previous literature (6,16,17). Lucas-Cuevas et al (6) did find a significant difference between a distal and proximal location at 2.2, 2.8, and 3.3 m·s −1 .…”

“…Accelerometers were attached close to the distal end and to the anteromedial aspect of the tibial; however, no clear participant-specific clarification was given (6). The results of (6,16,17) show the importance of the location of the accelerometer in PTA estimates. The nonsignificant difference between peak proximal and distal accelerations found here can be explained by the fact that the IMUs could be located closer to each other at the tibia, resulting in a smaller difference between the distal and proximal IMU accelerations.…”

“…In previous work, Lafortune and Hennig (18) used high-speed video recording to estimate centripetal acceleration during running, and showed that this could be as high as 50 m•s −2 proximally at the tibia. In other studies, significant differences between distal and proximal PTA estimates were found (6,16,17). However, only accelerometers were used in these studies, and therefore, it was not possible to take into account the contribution of the centripetal and tangential components.…”

“…Even though the tibia is often considered a rigid body, the location of the sensor at the tibia influences PTA (14)(15)(16)(17). Because the tibia is a rotating segment around the ankle joint during stance, acceleration measured by an accelerometer does not only consist of acceleration caused by impact with the ground (18).…”

“…One needs to take into account gravitational acceleration, but also location-dependent rotational accelerations like centripetal and tangential accelerations. However, this is often not complied with because the typically used accelerometers cannot measure the kinematics needed to assess gravitational, centripetal, and tangential acceleration (14,15,17). The generally used assumption that PTA can be measured with an accelerometer anywhere on the tibia, because the tibia is a rigid body, is not correct because distal and proximal peak accelerations measured by an accelerometer differ significantly (6,14,16,17).…”

Purpose Peak tibial acceleration (PTA) is defined as the peak acceleration occurring shortly after initial contact, often used as an indirect measure of tibial load. As the tibia is a rotating segment around the ankle, angular velocity and angular acceleration should be included in PTA. This study aimed to quantify 3D tibial acceleration components over two different sensor locations and three running speeds, to get a better understanding of the influence of centripetal and tangential accelerations on PTA typically measured in running. Furthermore it explores tibial impulse as alternative surrogate measure for tibial load. Methods 15 participants ran 90 seconds on a treadmill at 2.8, 3.3, and 3.9 m·s-1, with IMUs located distally and proximally on the tibia. Results Without the inclusion of rotational accelerations and gravity, no significant difference was found between axial PTA between both IMU locations, while in the tangential sagittal plane axis there was a significant difference. Inclusion of rotational accelerations and gravity resulted in similar PTA estimates at the ankle for both IMUs, and caused a significant difference between PTA based on the distal IMU and PTA at the ankle. The impulse showed more consistent results between the proximal and distal IMU location compared to axial PTA. Conclusions Rotational acceleration of the tibia during stance differently impacted PTA measured proximally as well as distally at the tibia, indicating that rotational acceleration and gravity should be included in PTA estimates. Furthermore, peak acceleration values (such as PTA) are not always reliable when using IMUs due to inconsistent PTA proximally compared to distally on an individual level. Instead, impulse seems to be a more consistent surrogate measure for the tibial load.

This paper aims to optimize the running posture of college students by using the principle of rod model in biomechanics. Based on this, through experiments and analysis, this paper studies some posture problems existing in college students' running process, and analyzes the influence these problems may have on the speed and stability of college students, and finally puts forward some solutions. In this paper, firstly, through the analysis of college students' motion images in Sports-1M data set, the movement process of college students is grasped, and a biomechanical model of college students' running posture is established. The actual running posture of college students is compared with this model. Then, in the process of comparison, the paper finds some posture defects, such as the backward landing point of footsteps, too great knee flexion and so on, which may lead to extra friction and energy loss for college students and have a great impact on their sports process. Therefore, this paper uses the image data in the data set to detect the movement state of college students, and finds that the running posture of some college students has a significant impact on their running process, so this paper makes a series of adjustments and optimizations to the running process of college students. It includes the adjustment of running posture, such as the adjustment of knee joint and elbow joint, which provides reasonable suggestions for improving the speed and stability of college students to effectively reduce the pressure on college students' knee joint and other related parts. In addition, the paper also tests the muscle electrical signals and skin reactions of college students during exercise. The results show that the optimized posture can make more effective use of muscle strength and reduce skin friction and wear during simulated running. This paper provides new ideas and examples for the optimization of college students' running posture, and also provides reference for the application and exploration of biomechanics in sports training. In addition, the paper can improve the competitive level of college students and make some contributions to the development of sports.
