Difference between Adolescent and Collegiate Baseball Pitchers in the Kinematics and Kinetics of the Lower Limbs and Trunk during Pitching Motion
Pitching ball velocity the open kinetic chain joint moment ground-reaction force motion analysis
2015/8/28
The purpose of this study was to clarify the differences between
adolescent and collegiate baseball pitchers in the kinematic and
kinetic profiles of the trunk and lower limbs during the pitching ...
Fruit Flies Modulate PassiveWing Pitching to Generate In-Flight Turns
In-Flight Turns PassiveWing Pitching
2015/8/25
Flying insects execute aerial maneuvers through subtle manipulations of their wing motions. Here, we
measure the free-flight kinematics of fruit flies and determine how they modulate their wing pitch...
High-order accurate simulations of unsteady flow past plunging and pitching airfoils
Spectral difference method Plunging Pitching
2015/7/3
This paper presents simulations of unsteady flow past plunging and pitching airfoils using a high-order spectral difference (SD) method. Both third-order and fourth-order SD methods are employed...
Kinematic and Kinetic Profiles of Trunk and Lower Limbs during Baseball Pitching in Collegiate Pitchers
Throwing movement pitching ball velocity ground-reaction force lower limbs pivot and stride legs
2015/5/25
The purpose of this study was to clarify differences in the kinematic and kinetic profiles of the trunk and lower extremities during baseball pitching in collegiate baseball pitchers, in relation to d...
Effect of Pitching Delta Wing on Vortex Structures with and without Impingement Plate
PIV Delta wing Vortex breakdown Angle of attack Pitching
2009/10/12
Flow past the leading edge of a delta wing oscillating about its mid-cord in a pitch plane with a reduced frequency of K=0.74 generates primary vortices having mostly elongated shapes. Their shapes an...
COMPARATIVE EMG ANALYSIS OF THE SHOULDER BETWEEN RECREATIONAL ATHLETES AND JAVELIN THROWERS DURING ELEMENTARY ARM MOTIONS AND DURING PITCHING
shoulder electromyography biomechanics pitching
2009/8/26
Shoulder problems are common in throwing sports. Although there is still
much to learn, knowledge of sequential muscle activation about the shoulder is
expanding. Further elucidation of muscle activ...
Characteristics of Longitudinal Motions of a Planing Craft in Head Waves at Very High-Speed—Effect of Surging on Heaving and Pitching—
High-Speed Planing Craft Stability Longitudinal Motion Surge Heave Pitch
2009/5/12
In this study, characteristics of longitudinal motions of a planing craft running at very high-speed in regular head waves are experimentally and theoretically investigated. The results of experiments...
Propulsive performance and flow field characteristics of a 2-D flexible fin with variations in the location of its pitching axis
analytic network process (ANP) underwater multi-target tracking decision tracking logic
2011/9/13
The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis ...
Pitching Pennies: A Interactive Learning Tool for Quality Management
Quality Management statistical concepts
2018/3/15
Total Quality Management uses statistical concepts extensively. While students have
learned them to get through one or two semesters of statistics, they still seem to struggle
to apply them in appli...
