The development and validation of a fully functioning dynamically loaded, inertial, strength training and rehabilitation device was requested. The YoYo system integrates a multitude of exercises in one condensed design providing a versatile operational unit free from gravitational forces. An algorithm controlled by user input automatically adjusts the inertial load of the system to maintain a specified power output. The algorithm controls the inertial load by dynamically adjusting the radial position of rotating masses. Additionally, a retract mechanism was developed to eliminate the need for user specific anthropometric adjustments of the device and to ensure constant tension on the cables eliminating jerk on the user. Upon completion of the device, a biomechanics analysis will be performed to validate user loads, joint angles, and the performance of the device against benchmarked strength training systems.

Boise State University has had a MiniBaja team since 2004 and every year the team is striving to produce the optimal vehicle. In 2005 the team used a trailing arm rear suspension that gave them substantial suspension travel as well as CNC machined front spindles that proved to be a light weight and durable feature to the car. In 2009 the car was built with durability in mind and all though nothing failed on the car it was too heavy and large to be competitive. Lastly in 2011 the MiniBaja had trouble with maneuverability due to a small cockpit and unsatisfactory steering geometry. One thing that has remained unchanged throughout several years was the use of a multi-speed gear box. The multi-speed gear box has been a major hindrance due to having a gear ratio that was not optimal for power transfer from the motor to wheels. The 2012 Boise State MiniBaja team proposes to build the most advanced vehicle to date by addressing each of the advantages and disadvantages of the previous cars.

Purpose: The team will use the vehicle in a competition that stresses the need for a fast, lightweight vehicle that is capable of conquering any terrain. To this end, the following criterion will be addressed during the development of the vehicle:

  • Weight
  • Safety
  • Max speed 42 MPH
  • Well handling suspension
  • Drive train function
  • Aggressive steering

Solution: The critical areas of design will be the suspension, drive train, and frame. Each of these subcategories must be designed in a way to achieve the fastest most maneuverable MiniBaja. These goals will be attained through a light frame, well designed drive train, and precision suspension geometry; all of which will be designed and optimized using the computer program SolidWorks and Microsoft Excel.To save weight, items on the car that were previously made out of steel will be replaced by aluminum or a composite material. Safety will be regulated by strictly following the SAE rules for designing a MiniBaja race vehicle. To obtain a max speed of 42 miles per hour a gear box has been designed and will be machined here at BSU, which will give a top speed of 42 MPH while also reducing the rotating mass in the gear box by 30%. In addition, the drive chain has been removed from the system, which will increase efficiency by about 15%. The last criterion to be addressed is the need for improved steering which will be accomplished by using a custom designed steering quickener. The quickener will increase the amount of front wheel deflection per revolution of the steering wheel by 1:2. These changes will make the car more agile and increase the cars overall performance giving Boise State an advantage over other competitors.

Effectiveness of an 8-Week Dryland Training Program in Adult Recreational Ice Hockey Players http://scholarworks.boisestate.edu/ed_12/3 http://scholarworks.boisestate.edu/ed_12/3 Fri, 13 Apr 2012 09:59:10 PDT Dry land training is a strategy used to condition ice hockey players when they cannot get time on the ice. The purpose of this study was to examine the effects of an 8-week dry land hockey training program on off- and on-ice performance in adult recreational hockey athletes (n = 25). Each week, the athletes attended two dry-land sessions that consisted of a general warm-up, a dynamic warm-up, speed and agility drills, and strength training. They were also assigned weekly “homework”. Participants were pre- and post-tested for changes in vertical jump (cm) 4-jump average, long jump (cm), push-ups (reps), bent knee v-ups (reps), and an on-ice 35m sprint (sec) and Cornering S test (sec). Paired t-tests with Bonferoni corrections for multiple testing were used to assess changes. Eighteen participants (72% female and 28% male; 39.39 + 6.61 yrs), with an 80% attendance rate for the sessions, and 50% homework completion took part in pre- and post-tests.

Athletes significantly improved their scores in long jump (+53.10 cm), bent knee V-ups (+7.00 reps), and push-ups (+5.07 reps) for off-ice tests, and they significantly improved their cornering s-test scores for on-ice tests. The intensity of the workouts, the group setting, and the hockey specific exercises were all aspects of the program that the athletes enjoyed. Recommendations for improvement included having the program during the off-season rather than pre- and in-season, and using a more hockey specific general warm-up. This study demonstrates that dryland hockey training may result in increased horizontal jumping ability (long jump), core strength (v-ups), and upper body strength (push-ups) off the ice, and enhanced agility (cornering s-test) on the ice. More research should be completed to validate these findings due to the lack of a control group, small sample size, and athletes’ additional uncontrolled activity.

Classroom Environments http://scholarworks.boisestate.edu/ed_12/2 http://scholarworks.boisestate.edu/ed_12/2 Fri, 13 Apr 2012 09:53:53 PDT This inquiry project is about the classroom environment related to spacial organization, group work, transition time, and behavior management. The problem observed was that much of the school day was lost during transitions between language arts and mathematics, as well as many students were demonstrating off-task behavior. The project looks at data from behavior monitoring and transition times in an attempt to make the school day more efficient. By researching and implementing changes to the spacial, organizational, and group dynamics the time lost between transitions, as well as the occurrence off task behavior was reduced.

]]> Katrina Painter A Study of the Availability of Multicultural Children's Literature in Treasure Valley Schools: Quality, Access and Inclusion http://scholarworks.boisestate.edu/ed_12/1 http://scholarworks.boisestate.edu/ed_12/1 Fri, 13 Apr 2012 09:23:38 PDT The purpose of this study is to conduct an analysis of the availability of quality multicultural children’s literature in Treasure Valley elementary schools. Of particular interest are several schools from the Boise and Kuna School Districts. Four schools will participate in the study, including at least one Spanish/English dual immersion school or program. Current research suggests multicultural literature supports the psychosocial well-being of students in all classrooms. Exposure to a variety of cultures increases awareness and acceptance among students, Dixon-Krauss (2001) cite evidence that reading multicultural literature “encourages children to reaffirm the values of their own culture and come to appreciate those of others” (p.80). Furthermore, multicultural literature, defined as literature that accurately portrays diverse views and cultures, has a significant impact on students’ developing identities. For these reasons this study focuses on the multicultural literature availability and content of school libraries in elementary schools. In this study I will investigate the availability, or lack thereof, of multicultural literature and the quality of the multicultural literature available in the school libraries by analyzing the library’s multicultural collection using a critical criteria to evaluate the books. This study will also take into account the need for multicultural literature in the particular schools by comparing the demographic population of the schools and the relationship to the library’s inclusion or lack of inclusion of multicultural literature. This study will prove useful to teachers, administrators, librarians, and parents when making decisions in regards to literature purchases and donations for school libraries. It also provides critical information that can be used to analyze student levels of engagement with library resources.
