Factors related to creating force-velocity and load-velocity profiles with the squat jump
… the ability to rapidly generate high levels of force is an important factor underpinning vertical jump performance. Recently, it has become popular to use forcevelocity (FV) and load-velocity (LV) profiles created from progressively loaded squat jumps (SJs) to guide the resistance training …

Body Sway and Aim Point Fluctuation in Rifle and Pistol Shooters
… study examined the effects of quantisation of force plate data used to measure body sway and the relationship between this body sway, aim point fluctuation and performance in shooting. Quantisation error in and resolution of selected body sway parameters were calculated from force plate data …

The Force Floor: Design and Development of a Low-Cost 3D Force Sensing Area Which Utilises Machine Learning to Estimate 3D GRF and CoP from Single-Axis Loadcells
Along with motion capture tools, ground reaction force (GRF) sensors form the crux of objective biomechanical analysis. Advances in computer vision have significantly lowered the costs associated with 3D motion capture, but the same cannot be said of 3-axis force plates – the gold standard for GRF …

The Validity of The VmaxPro during Countermovement Jump and Back Squat Performance
… jump (CMJ) against a gold standard force plate. Squat variables assessed included mean concentric velocity (MCV), mean concentric power (MCP), depth, and duration while CMJ variables assessed included MCV, MCP, depth, duration, and jump height. Squat variables were assessed across 3 …

Whole-Body Vibration and Its Effects on Electromechanical Delay and Vertical Jump Performance
… measured using tibial nerve stimulation and a force plate. EMD was recorded as the lag time between the initiation of gastrocnemeus stimulation and plantar flexion force production. Vertical jump was measured using a force plate and subjects' flight time. The factorial ANOVA results showed no …

An instrumentation system for the measurement and display of the dynamic force distribution under the foot during locomotion
… have been proposed for recording the dynamic forces acting on the foot are either too complex for clinical practise or there is difficulty in relating the measured force distribution to the physical surface of the foot. The system that has been developed measures the vertical foot/ground …

Evalution of a Model for Experimentally-Induced Osteoarthritis in the Hip Joint of the Dog
… followed by application of an ilial bone plate, causing rotation of the acetabulum to reduce dorsal coverage of the femoral head. Sham group dogs received identical osteotomies but were plated in normal orientation. All dogs had force plate and subjective lameness evaluations …

The validation of muscle power output measures in lower and upper body resistance exercises
… reliability and comparability of measurements of force, velocity and power measured simultaneously during upper and lower body resistance exercises for the following three methods: a) power derived from ground reaction force, i.e. using a force plate (FP), b) power derived from the displacement of …

The effect of surface compliance on the cost and benefit of performing drop-jumps
… cost was quantified using peak ground reaction force (GRF) (FPEAK), time to peak GRF (TFPEAK) and loading rate (LR). The benefit was quantified using lower extremity stiffness (K) and amortization phase (AMORT). Ten female subjects performed five DJ trials each on a force plate (C1), turf …

The relationship between lower limb power and anthropometric characteristics and gymnastics success
… jump, and a handstand push-off task on a force plate. Participants had circumference measures of calf and thigh and leg length taken. A DXA scan measured fat mass and lean mass. Vault success was measured using the highest vault score of the season as well as a standard vault in which the …

The effect of trunk stability and leg strength training on vertical take-off velocity in athletes
… groups for vertical take-off velocity using a force plate and fatigue index using a repeated vertical jump test. Pre-training take-off velocity and pre-training body mass were used as co variates. After three weeks of training, only the TS group had a significantly greater vertical take-off …

Physical and Anthropometric Factors Influencing the Isometric Strength in Key Positions of the Conventional Deadlift in Powerlifters
… powerlifters performed isometric pulls on a force plate at 3 key positions of the deadlift (at the floor, just above the patella, and 5-6 cm short of lockout) and the mid-thigh pull (MTP). RM ANOVA revealed that forces generated at each bar height differed significantly (F(3,39) = 51.058, …

Upper extremity vertical ground reaction forces during the back handspring skill in gymnastics: A comparison of various braced vs. unbraced techniques
… of a back handspring. Vertical Ground Reaction Forces (VGRF) sustained at the hand, time to peak VGRF, and total time of hand contact on the force plate were assessed for each condition per subject. The results indicated no significant difference in the VGRF, time to peak VGRF, and total time of …

Ground Reaction Force Differences Between Running Shoes, Racing Flats, and Distance Spikes in Runners
To measure the differences in ground reaction forces between running shoes, racing flats, and distance spikes, twenty intercollegiate distance runners ran across a force plate at 6.7m/s (for males) and 5.74m/s (for females) in each of the three types of shoes. In order to control for differences in …

Using fractal dimension analysis to improve clinical balance and mobility assessments for discriminating fallers from non-fallers : a cross-sectional analysis
… reliability of measures derived from a portable force plate was investigated in both young and elderly asymptomatic groups in studies I and 2. In studies 3 and 4 fallers were compared against non-fallers across a combination of clinical outcome measures, traditional, and FD COP analysis. Further, …
