We evaluated 18 methods capable of identifying initial contact (IC) and terminal (TC) gait events during human running using data from a single wearable sensor on the shank or sacrum. adapted created code to automatically execute each method, then applied it identify 74 runners across different foot strike angles, surfaces, speeds. To quantify error, estimated were compared ground truth time-synchronized force plate. Based our findings, with shank, we recommend Purcell Fadillioglu method for...
Inertial measurement units (IMUs) provide exciting opportunities to collect large volumes of running biomechanics data in the real world. IMU signals may, however, be affected by variation initial placement or movement during use. To quantify effect that changing an IMU's location has on data, a reference was 'correctly' placed shank, pelvis, sacrum 74 participants. A second 'misplaced' 0.05 m away, simulating 'worst-case' misplacement movement. Participants ran over-ground while were...
Twenty-seven methods of estimating vertical ground reaction force first peak, loading rate, second average, and/or time series from a single wearable accelerometer worn on the shank or approximate center mass during running were compared. Force estimation errors quantified for 74 participants across different surfaces, speeds, and foot strike angles biases, repeatability coefficients, limits agreement modeled with linear mixed effects to quantify accuracy, reliability, precision. Several...

Running is often recommended as a way to increase physical activity, given its purported health benefits. However, running associated with high rates of musculoskeletal injury. Both range motion (ROM) and muscular weakness have been suggested potential risk factors for PURPOSE: To investigate whether baseline measures or ROM correlate injury development. METHODS: Baseline hip, knee, ankle isokinetic flexion extension data were collected from 92 runners (41 male, 27.9±9.1 years old) at...
Running-related injury (RRI) may be caused by combinations of load magnitudes and numbers exceeding musculoskeletal structure capacity. Few methods exist, however, to quantify external loads (vertical ground reaction forces; vGRFs) during running in ecologically valid settings. PURPOSE: Develop models accurately estimate vGRF second (“active”) peaks from iliac crest sacrum accelerations. METHODS: Anthropometric sex data were collected 40 runners. Runners wore inertial measurement units...
During joint actions, individuals coordinate their movements in space and time to achieve common goals. It has been suggested that action co-representation, a process which co-actors represent each other’s responses, facilitates action. One of the methods used explore Joint Simon (JS) task, revealed when pairs sit next other, participants’ response times targets presented front them are shorter than partner. The co-representation account this effect holds it emerges due facilitatory...
