Comparison Of Three Base Stealing Techniques In Division I Collegiate Baseball Players, Sean Boss
Comparison Of Three Base Stealing Techniques In Division I Collegiate Baseball Players, Sean Boss
Dissertations and Theses @ UNI
The problem that baseball coaches face is which base stealing technique is most effective. The purpose of this study is to compare three base stealing techniques (crossover step (CS), jab step (JS), and drop step (DS)) on initial sprint kinematics and steal time in Division I baseball players. This paper will address the stretch shortening cycle (SSC) and its effects, the false step technique, sprinting technique, and acceleration. This research will provide coaches with the knowledge and educate them on which technique provides greater sprint speeds. The method for research was experimental, repeated measures design to determine the effects of …
Biomechanical Differences In The Weightlifting Snatch Between Successful And Unsuccessful Lifts, Jack Rummells
Biomechanical Differences In The Weightlifting Snatch Between Successful And Unsuccessful Lifts, Jack Rummells
Dissertations and Theses @ UNI
The purpose of this study was to determine what differences exist between several kinematic variables between failed and successful attempts in the snatch lift. Six female Weightlifters at the 2015 American open were measured for kinematic variables via videotape during competition. The results show that differences existed in the angle of the shoulder at peak barbell height and the catch height, along with the amount of separation between the lifter and barbell at peak height. Significant differences were also found at the angle between the barbell and lifter center of mass. This study was a first step toward understanding the …
Differences In Landing Impulses Between The Traditional And Swing Blocking Style In Volleyball, Jana Geertruida Braakhuis
Differences In Landing Impulses Between The Traditional And Swing Blocking Style In Volleyball, Jana Geertruida Braakhuis
Dissertations and Theses @ UNI
Blocking is an important part in the game of volleyball. Previous research has shown that the swing blocking style leads to a greater jump height, penetration over the net and effective blocking area compared to the traditional blocking method. No available research has been found investigating the differences in landing. The purpose of this study was to examine the differences in landing impulses, landing time and vertical ground reaction forces (vGRF) between the traditional and swing blocking style in volleyball. Therefore, eight female collegiate volleyball players were filmed in high definition at 60Hz performing successful trials of both blocking styles. …
