However, running is an impact activity that can lead to overuse injuries such as tibia stress fractures and patellofemoral pain syndrome. It is reported that both inter-limb asymmetries and fatigue are risk factors for non-contact injuries (Heil et al., 2020). Thus, this thesis aimed to examine the impact of running-induced fatigue on lower extremity symmetry in recreational runners. Twenty recreational runners were recruited in this study. Participants performed a fatigue protocol on a motorized treadmill, marker trajectories were collected before and after the fatigue protocol using a Vicon eight-camera motion capture system. OpenSim (Delp et al., 2007) was used for calculating hip, knee, and ankle joint kinematics.\nInter-limb asymmetries can be analyzed using discrete and continuous methods. Symmetry angle (SA) is the measurement to quantify the differences between the lower extremities. SA serves as a robust tool since it is a dimensionless metric without the reference number. A Wilcoxon signed-rank test was used to compare the SA for joint angles before and after fatigue protocol. In comparison, Statistical parametric mapping (SPM) as a continuous analysis was applied to the pre- and post-fatigue measurement to analyze the time series data.\nAfter fatigue, the SA of the hip peak abduction angle significantly decreased by 7.9% after the running-induced fatigue protocol (p=0.021). Meanwhile, the SA of peak internal rotation after fatigue was significantly higher (9.8%) than that before fatigue (p=0.023). However, SPM results failed to show any difference in the pre- and post-fatigue measurements between the limbs. Although SA has been successfully proved as a reliable indicator to quantify symmetry, future studies should consider continuity by using time-series symmetry indices.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-06-26T10:48:19Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-06-26T10:48:19Z (GMT).
