BUS, S. A. Ground Reaction Forces and Kinematics in Distance Running in Older-Aged Men. Med. Sci. Sports Exerc., Vol. 35, No. 7, pp. 1167-1175, 2003.PURPOSE The biomechanics of distance running has not been stu
Individuals with unilateral transfemoral amputation are prone to developing health conditions such as knee osteoarthritis, caused by additional loading on the intact limb. Such individuals who can run again may be at higher risk due to higher ground reaction forces (GRFs) as well as asymmetric gait...
This study examined vertical ground reaction forces and their association towards supporting brief and prolonged musculoskeletal performance in female adolescent soccer players. Methods Twenty female soccer players with an age of 19.6 ± 1.3 (y), including 3-goal keepers, 9-defenders, 4-mid-fielders...
This chapter provides a description of ground reaction forces (GRFs) in gait, detailing the technology used to measure them and their use in gait analysis. Representative ground reaction force data is provided, and information on how data is analyzed and interpreted is discussed. In addition, exa...
In the first test, ground reaction forces and stride characteristics were measured at each running speed. In the second test, running economy at the speed of 3.89 meters per second and maximal oxygen uptake were determined. The researchers found that, of all the stride characteristics measured ...
The inverse dynamics simulation19 determines joint torques, muscle contraction forces, and intra-articular contact forces from measured body motions and external forces, such as gravity and ground reaction forces. These simulations assist in understanding injury mechanisms, including ligament tears and ...
Thus, subtle events (e.g. start of downward movement) can be easily observed in the yank-time signal. Introduction Locomotion results from forces produced by an animal against a substrate, i.e. water, air or ground. In land animals, the ground reaction forces resulting from internal (e.g...
In those cases, the onset of such failures does not lead to a residual strength problem because the rotating structures have loads dominated by centrifugal forces. The resulting lost bending and torsional stiffness leads to operational conditions that are relatively easily detected as vibrational noise...
loading has led to fewer running-related injuries (62% lower injury risk) in novice runners2. These runners could reduce the maximum instantaneous vertical loading rate of the ground reaction force2, an impact measure that has been correlated with tibial shock during level over-ground running11,...
Baker [26] also indicates that for a large body, a simulation of the atmospheric boundary layer should also be present in the wind tunnel in order to approximate the forces and moments on full-scale trains. The symmetry method (or mirror-image method) is not commonly used experimentally for...
