The Effects Of Vertically-Oriented Resistance Training On Golf Swing Performance Variables, Austin R. Driggers
The Effects Of Vertically-Oriented Resistance Training On Golf Swing Performance Variables, Austin R. Driggers
Electronic Theses and Dissertations
The purpose of this study was to examine the effects of vertically-oriented resistance training on golf driving performance. Ten Division-I collegiate golfers completed 2 resistance training sessions per week for 10 weeks during the fall tournament season. Pre- and posttraining assessments of strength-power and golf performance were compared. To assess strength-power, jump height, peak force, and peak power (PP) were measured from static and countermovement (CMJ) vertical jumps; peak force and rate of force development from 0-250 ms were measured from an isometric mid-thigh pull. Golf performance was assessed in terms of ball launch speed (BS), spin rate, carry yardage …
Kinetic Asymmetries During Submaximal And Maximal Speed Running, Devon H. Frayne
Kinetic Asymmetries During Submaximal And Maximal Speed Running, Devon H. Frayne
Masters Theses
An important issue for sports scientists, coaches and athletes is an understanding of the factors within a running stride that can enhance or limit maximal running speed. Previous research has identified many sprint-related parameters as potential kinetic limiters of maximal Center of Mass velocity (Chapman and Caldwell, 1983b; Weyand et al., 2001). Bilateral asymmetry is present for many of these parameters during running; however the degree to which such asymmetries change as running speed increases is unknown. It was hypothesized that asymmetries in key sprinting parameters would be larger at maximal speed than all other tested speeds. Kinematics and kinetics …
Performance Implications Of Rear Foot Movement In The Swimming Kick Start, Amber C. Hutchinson
Performance Implications Of Rear Foot Movement In The Swimming Kick Start, Amber C. Hutchinson
Electronic Thesis and Dissertation Repository
The performance implications of changing rear foot joint angles in the kick start were evaluated using a replicated version of the Omega OSB11 starting block. Maximal effort dives were collected for twenty-six competitive swimmers. The block was equipped with two tri-axial force plates to differentiate between forces applied to the rear foot rest and forces applied to the block. Two high-speed video cameras recorded hind-foot eversion and dorsiflexion angles. Competitive swimmers with larger hind-foot eversion movement have larger lateral kick plate forces, longer kick plate times, and larger contributions of the kick plate to total impulse. These swimmers also have …
