Number of successive cycles necessary to achieve stability of selected ground reaction force variables during continuous jumping. By the stability of the corresponding ground reaction force variables on a cycle-by-cycle chers have used different criteria and methods for determining stability of ground reaction force data for a. The relationship between gait mechanics and running ground reaction forces is widely regarded as complex. This viewpoint has evolved primarily via efforts to explain the rising edge of vertical force–time waveforms observed during slow human running. Existing theoretical models do provide good rising-edge fits, but require more than a dozen input variables to sum the force Cited by:
The study described here was designed to determine the number of successive cycles due to continuous, repetitive countermovement jumping which a test subject should perform in a single experimental session to achieve stability of the mean of the corresponding continuously measured ground reaction force (GRF) variables. A force platform was used to measure selected GRF parameters (peak and time to peak for vertical impact force, vertical active force, and horizontal braking force) during running at ms −1. Tibial bone geometry (cross-sectional dimensions and area) was calculated from a computerized tomography (CT) scan at the junction of the middle and.
the ground. In this paper we discuss biomechanical terms related to running and walking. We then use experimental ground reaction force data to calculate the impulse of running, speed-walking, and walking. We then mathematically model the vertical ground reaction force curves for both running and walking, successfully reproducing experimental Size: KB. When this action is performed continuously and repeatedly, the corresponding ground reaction force (GRF) time history is typically a series of distinctive pulses (Figure 1), which are the reaction to the force the body exerts on the supporting ground during the ‘contact phase’ of jumping. The pulses are separated by zero-force intervals which indicate ‘aerial phases’ of jumping when both feet leave the by:

Ground reaction forces are often used as a primary descriptive component in the analysis of the support phase of running. The purpose of this study was to investigate the changes in ground reaction force parameters during the support phase of the running stride at different running Cited by: In this study the variation in ground reaction force parameters was investigated with respect to adaptations to speed and mode of progression, and to type of foot‐strike.
Twelve healthy male subjects were studied during walking (– m s ‐1) and running (– m s ‐1). The subjects were selected with respect to foot‐strike Cited by: Reliability of selected ground reaction force parameters during walking. Human Movement Science 9, The purpose of this study was to determine the appropriate number of trials to establish a stable mean and the intraday and interday reliability of selected ground reaction force (GRF) parameters during by: Human Movement Science 2, Ground reaction forces are often used as a primary descriptive component in the analysis of the support phase of running.
The purpose of this study was to investigate the changes in ground reaction force parameters during the support phase of the running stride at different running by: Visual targeting was found to have a negligible affect on the measured gait parameters.
The magnitude, the timing and the variability of ground reaction force parameters were not influenced by constraining the subjects foot to the target area and were within the limits of previously published reports involving non-pathological gait.Cited by: Hamill J, McNiven S.

Comment on "the influence of running velocity and tidsole hardness on external impact forces in heel-toe rutting".Cited by: Vertical ground-reaction forces of experienced runners (12 male, 12 female) were obtained during overground and treadmill running at slow, preferred and fast self-selected running speeds.
For each runner, 7 mean vertical ground-reaction force parameters of the right leg were calculated based on five successful overground steps and 30 seconds of treadmill running Cited by: However, no study to date has analyzed the variability of the ground reaction force (GRF) to evaluate gait performance.
The GRF is regarded as a representative measurement of gait, because it is the external force involved in walking and it affects the acceleration of the body's center of mass (29).Cited by: The aim of this study was to determine the effect of the time between measures on ground reaction force running variability; 15 healthy men (age =.
To determine the differences in ground reaction forces between regular running shoes and competitive footwear, force plate data was obtained from 10 males ( ms -1) and 10 females ( ms -1) for each of three shoe by: Methods Vertical ground-reaction forces of experienced runners (12 male, 12 female) were obtained during overground and treadmill running at slow, preferred and fast self-selected running speeds.
Adaptation of kinetics response when running on different surface has been commonly measured by the ground reaction force (GRF). GRF was extensively been.
Biomechanics of sprint running has long been the sub-ject of scientiﬁc interest. Although a number of studies have described various aspects of ground reaction forces (GRF) and kinematics during sprinting, there is little in-formation available concerning the variability or repeata-bility of biomechanical parameters of sprint running.
