PURPOSE To examine the kinematic adjustments that runners make during an exhaustive run and to look at the effects these adjustments have on shock and shock attenuation. METHODS Ten recreational runners ran to volitional exhaustion on a treadmill at a velocity equal to their average 3200-m running velocity at maximal effort (average time: 15.7 +/- 1.7(More)
Generating consistent maximum ball velocity is an important factor for a baseball pitcher’s success. While previous investigations have focused on the role of the upper and lower extremities, little attention has been given to the trunk. In this study it was hypothesized that variations in pelvis and upper torso kinematics within individual pitchers would(More)
PURPOSE The purpose of this study was to determine whether electromechanical delay (EMD) was associated exclusively with the onset of tension from a resting state and whether EMD remained constant across different rates of force development. METHODS Twenty-four subjects (23.9 +/- 5.4 yr, 171.7 +/- 7.3 cm, 72.9 +/- 12.8 kg) performed isometric elbow(More)
BACKGROUND This study investigated the hypothesis that expressions of maximal and submaximal bilateral indices would not differ between older and young participants. METHODS Twenty older (73.3 +/- 4.4 years) and 21 younger (22.4 +/- 0.9 years) participants performed maximal voluntary isometric contractions of the elbow flexor muscles, using the right arm(More)
To reach the level of elite, most baseball pitchers need to consistently produce high ball velocity but avoid high joint loads at the shoulder and elbow that may lead to injury. This study examined the relationship between fastball velocity and variations in throwing mechanics within 19 baseball pitchers who were analyzed via 3-D high-speed motion analysis.(More)
Thirty-six participants performed bilateral and unilateral isometric elbow flexion trials at what they perceived to be 100, 75, 50, and 25% of maximal effort. Absolute bilateral deficits ranged from--16% at 25% effort to--10% at 100% effort. The deficit included a component independent of consciousness and a component inversely related to intensity(More)
The aims of this study were to identify differences in the centre of buoyancy (CB) and centre of mass (CM) locations of male and female collegiate swimmers, and to assess the influence that buoyancy has on freestyle kicking performance. Sixteen female collegiate swimmers (mean +/- s: age 19.1 +/- 1.2 years) had significantly more adipose tissue (20.2 +/-(More)
To determine if the central command signal associated with isometric exercise is mass-dependent, 20 subjects (nine male, 11 female; 23 +/- 1 years) performed four 5-min bouts of supine isometric exercise with a large (quadriceps; LEG) and small (forearm; ARM) muscle mass. For each extremity, one bout entailed maintaining a constant force (CF; 20% maximal(More)
This study investigated the accuracy of the direct linear transformation (DLT) and non-linear transformation (NLT) methods of 3-D cinematography/videography. A comparison of standard DLT, extrapolated DLT, and NLT calibrations showed the standard (non-extrapolated) DLT to be the most accurate, especially when a large number of control points (40-60) were(More)
