A Functional Agility Short-Term Fatigue Protocol Changes Lower Extremity Mechanics, Nelson Cortes, David Quammen, Shawn Lucci, Eric Greska, James Onate Jan 2012

A Functional Agility Short-Term Fatigue Protocol Changes Lower Extremity Mechanics, Nelson Cortes, David Quammen, Shawn Lucci, Eric Greska, James Onate

Human Movement Studies & Special Education Faculty Publications

The purpose of this study was to evaluate the effects of a functional agility fatigue protocol on lower extremity biomechanics between two unanticipated tasks (stop-jump and sidestep). The subjects consisted of fifteen female collegiate soccer athletes (19 ± 0.7 years, 1.67 ± 0.1 m, 61.7± 8 kg) free of lower extremity injury. Participants performed five trials of stop-jump and sidestep tasks. A functional short-term agility protocol was performed, and immediately following participants repeated the unanticipated running tasks. Lower extremity kinematic and kinetic values were obtained pre and post fatigue. Repeated measures analyses of variance were conducted for each dependent variable …


Swing And Launch Parameters In Approach-Iron Shots Hit With Varying Height And Trajectory In Golf, Samuel J. Robertson, Angus Burnett Jan 2012

Swing And Launch Parameters In Approach-Iron Shots Hit With Varying Height And Trajectory In Golf, Samuel J. Robertson, Angus Burnett

Research outputs 2012

The first aim of this study was to determine whether relationships existed between variability of swing and launch parameters and variability in shot outcome for straight golf shots. The second aim was to determine whether differences existed for swing and launch parameters in shots intentionally played with varying height and trajectory. Elite (n=20) and high-level amateur (n=22) golfers hit; 1) five straight shots of normal height and 2) nine shots of differing height (low, normal, high) and trajectory (straight, draw, fade). Variability of club attack angle, face angle and ball spin axis was significantly associated (p


Strength And Hypertrophy Responses To Constant And Decreasing Rest Intervals In Trained Men Using Creatine Supplementation, Tacito P. Souza-Junior, Jeffrey M. Willardson, Richard Bloomer, Richard D. Leite, Steven J. Fleck, Paulo R. Oliveira, Robert Simao Jan 2011

Strength And Hypertrophy Responses To Constant And Decreasing Rest Intervals In Trained Men Using Creatine Supplementation, Tacito P. Souza-Junior, Jeffrey M. Willardson, Richard Bloomer, Richard D. Leite, Steven J. Fleck, Paulo R. Oliveira, Robert Simao

Faculty Research and Creative Activity

The purpose of the current study was to compare strength and hypertrophy responses to resistance training programs that instituted constant rest intervals (CI) and decreasing rest intervals (DI) between sets over the course of eight weeks by trained men who supplemented with creatine monohydrate (CR).


Biomechanics Of Staircase Exercises., Sami Faris Almashaqbeh Jun 2010

Biomechanics Of Staircase Exercises., Sami Faris Almashaqbeh

Student Works (2010-2019)

Exercises provide many important health benefit to individuals. People should therefore be encouraged to change their life style by including some kinds of physical activities into their daily routines. A staircase provides free and easy access as a tool for exercising. A wide variety of exercises has been proposed to be done on a staircase. Among them are walking up and down stairs ' with the hands behind the head, walking holding dumbbells, walking in cross-step manner, and lateral stepping. The joint-specific differences in the kinematics and kinetics patterns between such exercises and regular stair climbing may be used to …


The Effects Of Opposition And Gender On Knee Kinematics And Ground Reaction Force During Landing From Volleyball Block Jumps, Gerwyn Hughes, James Watkins, Nick Owen Jan 2010

The Effects Of Opposition And Gender On Knee Kinematics And Ground Reaction Force During Landing From Volleyball Block Jumps, Gerwyn Hughes, James Watkins, Nick Owen

Kinesiology (Formerly Exercise and Sport Science)

The aim of the study was to examine the effect of opposition and gender on knee kinematics and ground reaction force during landing from a volleyball block jump. Six female and six male university volleyball players performed two landing tasks 1) an unopposed and 2) an opposed volleyball block jump and landing. Knee kinematics were recorded by a 12 camera motion analysis system (120 Hz) and ground reaction force was recorded by a force platform (600 Hz) during landing. The results showed a significant effect for level of opposition in peak normalized GRF (p = .04), knee flexion at ground …


The Effectiveness Of A Specialized Upper Body Stretching Protocol On Ncaa Division I Athletes, Brandon M. Howard Dec 2009

The Effectiveness Of A Specialized Upper Body Stretching Protocol On Ncaa Division I Athletes, Brandon M. Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous studies with college athletes determined that the shoulder girdle plays a vital role in a variety of athletic activities. The previous research showed that a decrease in shoulder range of motion (ROM) was associated with a higher risk injury. Decreased shoulder ROM was shown to be a primary reason that many athletes were unable to perform many overhead lifting variations within their strength and conditioning programs.

The purpose of this research was to evaluate a group of athletes by means of a postural assessment using the overhead squat test. This study consisted of a pretest-post test control group design. …

Is There A Difference In Cortical Representation Between Dominant And Non-Dominant Arm Muscles Of Elite Badminton Players?, Dylan J. Edwards Jan 1995

Is There A Difference In Cortical Representation Between Dominant And Non-Dominant Arm Muscles Of Elite Badminton Players?, Dylan J. Edwards

Theses : Honours

Training for sport involves the development of skill and coordination. The physiological changes associated with skill acquisition are complex and at present poorly understood. One of the areas in the central nervous system thought to be involved with skill acquisition is the cerebral motor cortex where localised areas are responsible for controlling specific muscle groups. Learning or improving a motor skill may require reorganisation of the cortical areas controlling relevant muscles to accommodate the new skill. To test this idea we studied a group of elite badminton players that were highly skilled in their dominant playing arm. Transcranial magnetic stimulation …
