Trunk Rotation Movement In Tennis Backhand, Hsin-Chen Fanchiang
Trunk Rotation Movement In Tennis Backhand, Hsin-Chen Fanchiang
All-Inclusive List of Electronic Theses and Dissertations
This study analyzed the effects of gender, strike technique, power level, and trial factors on tennis athletes performing backhand strokes with the incoming ball launched by a serving-stand. Five male and five female college tennis athletes volunteered as subjects. Each subject had 25 data points including joint centers of right and left sides for the 5th metatarsal, lateral malleolus, knees, hips, shoulders, elbows, wrists and MP joints, chin, forehead, seven points on the racket (handle, head, neck, upper right and left rims, and lower right and left rims), and the ball were recorded by two video cameras (60Hz). Each of …
Mental Imagery And Basketball: A Comparison Of Cognitive-Specific And Flow Imagery, Evan Welo
Mental Imagery And Basketball: A Comparison Of Cognitive-Specific And Flow Imagery, Evan Welo
Psychology Honors Projects
Flow is a psychological state that is associated with optimal performance. Sports such as basketball are conducive to an individual experiencing flow because they have rules that structure and focus attention. Past research indicates that sports related mental imagery practice improves athletic performance; however few studies to date have systematically included the characteristics of flow in their sports mental imagery interventions. The present study compared the efficacy of a ―flow‖ and a standard basketball mental imagery intervention at improving performance on a basketball-shooting task. No significant differences were found between groups, but both reported increases in flow experiences.
The Effect Of Concurrent Cell Phone Use And Walking On Gait Characteristics, Jennifer Marie Aldridge
The Effect Of Concurrent Cell Phone Use And Walking On Gait Characteristics, Jennifer Marie Aldridge
UNLV Theses, Dissertations, Professional Papers, and Capstones
This study examined the effects that cell phone use has on gait and situation awareness. Subjects (n=18; 24.67±3.60 yrs) completed three five-minute treadmill walking conditions (self-selected speed): (1) CONTROL (walking only), (2) TALK (walking and talking), and (3) TEXT (walking and texting). The number of detected lights presented in the visual field was recorded, as were kinematic data of the feet. Using a one-way repeated measure ANOVA it was determined light detection (F (2,17) =39.777, p<0.001) and TCmin (F(2,17) =8.574, p=0.001) were different between conditions. Specifically, light detection decreased during TEXT (2.6±2.2 lights) versus TALK (5.8±0.05 lights, p<0.001) or CONTROL (5.9±0.05 lights, p<0.001); TCmin decreased …
The Effect Of Random, Blocked, And Transition Practice Schedules On Children's Performance Of A Barrier Knockdown Test, Gregory C. Snider
The Effect Of Random, Blocked, And Transition Practice Schedules On Children's Performance Of A Barrier Knockdown Test, Gregory C. Snider
Master's Theses
The purpose of this research was to examine whether a transition schedule of contextual interference facilitated learning in retention and transfer equal to or better than random and blocked schedules among children. The author selected participants from the central coast of California and from youth activity leagues. The author selected children between the ages of 10 to 13 with a mean age of 11.5. There were a total of 36 subjects, half male and half female. Unfortunately, due to computer error, only data from 15 subjects were saved and available for analysis. Researchers randomly assigned participants to one of three …
The Effects Of Alterations To Upper Limb Inertial Properties On Vertical Point-To-Point Movement, Adrian K. Hongo
The Effects Of Alterations To Upper Limb Inertial Properties On Vertical Point-To-Point Movement, Adrian K. Hongo
Master's Theses
Purpose: Several studies have examined intralimb coordination between the shoulder and elbow joints during target-oriented movements. These studies have observed consistent patterns in coordination despite changes in movement variables such as speed, direction, and inertia. Researchers used intersegmental dynamics to quantitatively analyze these patterns between shoulder and elbow joints while systematically changing values of these movement variables. Some studies have examined central nervous system adaptations to inertial changes at the elbow and entire arm during a movement, but none have examined inertial changes to the upper limb. Methods: Five male and five female participants aged 27 to 39 years (mean …
