This study's purpose was to determine if performing a push up on a BOSU® ball and on an exercise bench influenced EMG muscle activity when compared to the activity of a push up on a stable surface in females. Eighteen females were recruited from a convenience sample of college students. The pectoralis major, rectus abdominus, and external oblique muscles showed the greatest EMG muscle activity. The posterior deltoid showed the lowest activity. Overall, the push up performed on the bench showed the greatest EMG muscle activity compared to the other types of push ups. <br>description: Paper presented to the 5th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, May 1, 2009. <br> Thu, 30 Apr 2009 22:58:59 GMT http://hdl.handle.net/10057/1406 title: Heart rate changes comparing free weight vs elastic resisted tubing authors: Robertson, Mark; Odgers, Jarvis; Young, Jon; Wilson, Cam; Reiman, Michael <br>abstract: During lifting, heart rate and blood pressure have been shown to rise because of an increase in intra-abdominal pressure. This increase in pressure is known as a Valsalva maneuver. However, little research has been conducted to compare heart rate changes that occur with traditional weight lifting versus elastic band resistance. Changes in heart rate that occurred while lifting free weight compared to lifting with elastic band resistance were therefore examined. 30 healthy subjects with an age range of 18-40 were tested. Heart rate changes were recorded using a 12 lead ECG, with a baseline measurement established before lifts were performed. Testing consisted of subjects lifting roughly 40% of their body weight from the floor to waist height and then returning the weight to its original starting position. All subjects alternately performed lifts with both free weights and elastic bands. Subjects were required to rest between lifts to allow heart rate to return to baseline measurement. Results indicate that heart rate did increase significantly in both the free weight and elastic band resisted groups when compared to baseline measurements. There was no significant difference found when comparing the difference in change of heart rate for the second lift between free weight lifting and elastic band resistance. A mixed 2- way ANOVA was used to determine if there is a significant difference in HR changes between the 2 lifts. <br>description: Paper presented to the 4th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, April 25, 2008. <br> Thu, 24 Apr 2008 22:58:59 GMT http://hdl.handle.net/10057/1365 title: Kansas employers compliance with healthy people 2010 initiatives targeting health promotion in the workplace authors: Clark, Jennifer; Bunton, Patricia <br>abstract: The CDC and the Department of Health and Human Services has set a goal to increase the number of health promotion programs in the workplace as part of the Healthy People 2010 Initiative. Health promotion programs are designed to promote health in the workplace by targeting health risk reduction and actively preventing the onset of disease. The purpose of this study is to determine the number of Kansas employers currently offering a health promotion program, what types of services are offered, what barriers exist for employers who are not currently offering a program, and to compare the size of the company to these findings. Methodology: Five hundred companies were selected from the database Reference USA and were divided into 5 groups according to size. Surveys were sent to each employer and frequencies of answers were tabulated and compared to company size. Results: 154 surveys were returned for a 30.8% response rate. 60% of respondents stated that they offered a health promotion program. 73% of respondents employing more than 250 people offer a program and only 45% of companies employing less than 250 people offer a program. Discussion: According to survey respondents, larger companies in the state seem to be on target with the CDC’s goal of at least 75% of employers offering a health promotion program, while smaller companies, those with less than 250 employees, lag behind. <br>description: Paper presented to the 4th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, April 25, 2008. <br> Thu, 24 Apr 2008 22:58:59 GMT http://hdl.handle.net/10057/1362 title: Acute effect of 30 and 60 second static hamstring stretch on knee flexion strength authors: Carter, John W.; Dickinson, Jessica; Doty, Shawna; Mettling, Jason; Rohrberg, Justin <br>abstract: This study was designed to determine if there is a difference in torque produced with a hamstring curl after a 30 second and 60 second passive static hamstring stretch. Our study included 50 participants (13 males, 37 females) between the ages of 20 and 29. Excluded subjects included individuals with a history of surgery on their dominant leg (the leg they kick a ball with) and expecting mothers. The Lido Isokinetic Dynamometer was used to measure torque production (NM) of concentric knee flexion on two separate occasions no more than two weeks apart. The first testing session was performed without a pre-test stretch and the second was performed with a pre-test stretch. Statistical analysis revealed no significant difference in torque production between the 30 second and 60 second static stretching groups. <br>description: Paper presented to the 4th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, April 25, 2008. <br> Mon, 24 Mar 2008 22:58:59 GMT
