Comparison Of Two Training Programs On Acceleration Out Of The Break In American Football, Micah Adam Alba Dec 2008

Comparison Of Two Training Programs On Acceleration Out Of The Break In American Football, Micah Adam Alba

Theses and Dissertations

Athletes of American football need the ability to stop, start, and reach top speed in an efficient manner. Football players on the defensive side of the ball require the skill of stopping a backward run and accelerating to a forward run. This action is termed the break. Football players receive year-round training in an effort to improve performance. Yet, many times, these athletes may not focus specifically on the muscular systems that are unique to the position they play. The law of specificity states that the more specific the training is for the action required, the more beneficial the outcome. …

Using Pedometers As A Valid Method Of Determining Physical Activity Intensity Level, Alan M. Groves Dec 2008

Using Pedometers As A Valid Method Of Determining Physical Activity Intensity Level, Alan M. Groves

Theses and Dissertations

As researchers explore the benefits of using pedometers to assess physical activity they are discovering that intensity of physical activity may be estimated from steps per minute (SPM). The purpose of this study was to determine the SPM and kilocalories (kcals) expended associated with moderate physical activity in middle school students (12 - 14 years old). Methods: Ninety-three (49 boys, 44 girls) middle school youth between the ages of 12 and 14, walked on a treadmill at four different speeds (4.0, 4.8, 5.64, and 6.4 km/h) for three minutes at each speed. Each participant wore a pedometer in order to …

Effects Of Same-Day Strength Training On Bat Swing Velocity Of Male Collegiate Baseball Players, Anthony Loren Clah

Theses and Dissertations

The purpose of this study was to investigate the effect of same-day strength training on bat swing velocity of male collegiate baseball players. Sixteen male baseball players engaged in a preseason strength training program designed by the team's strength and conditioning coach. All subjects were tested for bat swing peak velocity immediately prior to ball impact for a non lifting day (NLD) by recording 10 swings with 30 seconds of rest in between swings. The next day, a lifting day (LD), all subjects tested on the NLD were tested four to six hours after the morning lifting session with the …
