Barrier Knockdown Test Control System For The Cal Poly Kinesiology Department, Regina M. Chapuis
Barrier Knockdown Test Control System For The Cal Poly Kinesiology Department, Regina M. Chapuis
Computer Engineering
The goal of this project is to design and implement a new control system for the LEDs and buttons on an existing Barrier Knockdown setup in the Cal Poly Kinesiology department. The Barrier Knockdown test is a testing apparatus in which subjects knock down a series of mechanical barriers in one of three patterns. The computer system times their reaction and movement time, and the test as a whole provides students with data to study the phenomenon of Contextual Interference. This system was previously controlled by an old computer setup that ultimately crashed. This project recreates the logic and user …
Variability Of Practice And Strength Training Periodization: When Theories Collide, Katherine Lauren Streder
Variability Of Practice And Strength Training Periodization: When Theories Collide, Katherine Lauren Streder
Master's Theses
The primary purpose of this study was to examine whether variability of practice enhances neuromuscular adaptations when compared to traditional strength training. The secondary purpose was to investigate whether there was a difference in perception of exertion between the two strength programs. Forty one subjects (23 women and 18 men) were assigned to either the control group or one of two treatment groups by a blocked-random method. Subject's one repetition maximum (1RM) for the kettlebell press and leg press were measured at baseline, after 4 weeks of training, and after 8 weeks of training. The treatment groups completed 8 weeks …
An Exploratory Biomechanical Analysis Of The Side-To-Side Swing Patterns Of Three Skilled Switch Hitters, Francesca Marie Castellucci
An Exploratory Biomechanical Analysis Of The Side-To-Side Swing Patterns Of Three Skilled Switch Hitters, Francesca Marie Castellucci
Master's Theses
The ability to successfully switch hit, or hit a baseball from both sides of the plate, requires a great amount of practice and coordination bilaterally. This study used three-dimensional kinematic and kinetic data to examine the swing patterns of skilled switch hitters in baseball. Three male minor league and division I collegiate switch hitters participated. Subjects stood on force plates and hit baseballs off a tee while their swings were recorded with a three-dimensional optical motion capture system. Each subject performed twenty total swings, ten from the right and ten from the left. The swings were digitally analyzed and the …
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 …
