Obesity is associated with early cardiovascular dysfunction and reduced muscle strength. Whole-body vibration (WBV) training may improve arterial function and muscle strength. The effects of WBV training on arterial stiffness (brachial-ankle pulse wave velocity, baPWV), wave reflection (augmentation index, AIx), brachial systolic blood pressure (bSBP), aortic systolic blood pressure (aSBP), heart rate variability, and muscle strength (one-repetition maximum, 1RM) were examined in 10 young (21±2 year) overweight/obese women (body mass index, BMI=29.9±0.8 kg m–2). Participants were randomized to a 6-week WBV training or non-exercising control (CON) period in a crossover design. WBV training (3 days × week) consisted of static …

Passive Vibration On The Legs Reduces Peripheral And Systemic Arterial Stiffness, Alexei Wong, Marcos A. Sanchez-Gonzalez, Ryan Gil, Florence Vicil, Song-Young Park, Arturo Figueroa

Health and Kinesiology Faculty Publications

Intermittent leg exercise (10 × 1-min sets) with whole-body vibration (WBV) decreases brachial-ankle pulse-wave velocity (baPWV)1 and leg PWV (legPWV) but not aortic PWV.2 As baPWV is an index of systemic arterial stiffness3 mainly influenced by aortic PWV (∼58%) and legPWV (∼23%),4 previously published results1, 2 suggest that WBV affects baPWV through peripheral but not central PWV. The post-exercise decrease in PWV is associated with vasodilation in the exercised limb.5, 6 Similarly, intermittent WBV (3 × 3-min sets)7 or passive vibration (PV)8 has been shown to increase blood flow in …

A Three-Dimensional Analysis Of Subtalar And Knee Joint Coupling During Running Over Obstacles, Tracy Allan Dierks

Student Work

Running has been associated with a number of lower extremity overuse injuries. Attention has been given to biomechanical factors, specifically, excessive pronation and excessive tibial rotation. It has been suggested that excessive tibial rotation is due to excessive foot pronation transferred through a coupling mechanism. The ankle and knee are mechanically linked via the tibia and excessive tibial internal rotation may delay tibial external rotation as the knee begins to extend. Increased impact forces have also been implicated as a cause of running injuries, although little is known about this possible relationship. Obstacle heights have been used previously to produce …

Relationship Between Reported Childhood And Adult Physical Activity, Kipp Ryan Kissinger

Student Work

It was the purpose of this research to examine the relationship between reported childhood and adult physical activity (PA), with special regards to the types of activities that correlate with habitual activity. Subjects were 249 male and female students age 19 to 30 years (M = 21.9 years) enrolled at the University of Nebraska at Omaha. Subjects were surveyed from all departments on campus. Subjects were asked to complete a survey instrument that assessed past and present PA. The results o f the current study reported that there is a significant positive correlation (r = 0.284, p < 0.05) between the total score of past childhood PA and present adult PA. When past PA was divided into preteen and adolescent periods, there were also significant relationships (p < 0.05) with all of the four indices of present PA (work, sport, leisure and total). Regression analysis explained 17.6 % of the variance in exercise when predicting adult PA from the total score of past PA. The prediction equation is as follows: Y ' = 27.761 + 0.775 (Xi) + 0.276 ( X 2 ) + 0.945 ( X 3 ) + 1.787 (3Ct) - 1.254 ( X 5 ) ; where Xi = number o f varsity athletic letters received as an adolescent, X 2 = informal activities as a preteen, X 3 = level of athletic ability or coordination in favorite sport as an adolescent, X4 = P.F.. classes as an adolescent, and X5 = activity level compared to peers as a preteen. It was concluded that there was a significant positive correlation (p < 0.05) between the total score of past PA and each of the four indices of present PA.

The Historical Transformation Of Swimming Into A Modern Leisure Activity, Stephanie J. Haas

Student Work

The purpose of this study is to trace the transformation of swimming from its earliest appearance in the literature to its contemporary form as a modern leisure activity. The processes of rationalization, legitimation and democratization are examined in pre-industrial, industrial, and post-industrial societies.

An investigation of the available literature disclosed negative attitudes toward swimming during the Middle Ages which caused a decrease in expressive uses of swimming. After this period, swimming's acceptance as a legitimate leisure activity continued to increase through the industrial and post-industrial eras. The democratization of swimming seemed limited to societies on the coasts of large bodies …

The Effect Of A Weight Training Program On The Happiness Of Young Women, Natalie Dowty

Student Work

An increasing body of research indicates that exercise has some positive psychological effects. But few studies focus specifically on weight training as the treatment, or happiness as the dependent variable. Additionally, much research has focused on psychological state changes from immediately before, to immediately following a physical activity. Little has been reported on the relationship between weight training and general happiness over a longer period of time, (i.e. three to four months). The purpose of this study was: (a) to determine the effect of beginning and maintaining a regular weight training program on the happiness of previously sedentary women, (b) …
