Balance Affects Prism Adaptation: Evidence From The Latent Aftereffect, Dobromir Dotov, Till D. Frank, Michael T. Turvey

Journal Articles

In prism adaptation experiments, the effect on throwing to a target is reduced (primary aftereffect is smaller) when the throwing condition with prisms removed (first test phase) is different from the throwing condition with prisms (the training phase). The missing adaptation, however, can be revealed through further testing (second test phase) in which the throwing condition during training is fully reinstated. We studied throwing underhand to a target flush with the floor. During training, participants wore left-shifting prism glasses while standing on the floor (Group 1) or on a balance board (Groups 2 and 3). Tests 1 and 2 following …

Which Type Of Sedentary Behaviour Intervention Is More Effective At Reducing Body Mass Index In Children? A Meta-Analytic Review, Y. Liao, J. Liao, C. P. Durand, G. F. Dunton

Kinesiology Faculty Publications & Presentations - Archive

Sedentary behaviour is emerging as an independent risk factor for paediatric obesity. Some evidence suggests that limiting sedentary behaviour alone could be effective in reducing body mass index (BMI) in children. However, whether adding physical activity and diet-focused components to sedentary behaviour reduction interventions could lead to an additive effect is unclear. This meta-analysis aims to assess the overall effect size of sedentary behaviour interventions on BMI reduction and to compare whether interventions that have multiple components (sedentary behaviour, physical activity and diet) have a higher mean effect size than interventions with single (sedentary behaviour) component. Included studies (n = …

Benefits Of Neuromuscular And Plyometric Training In Injury Prevention And Performance Enhancement, Bethanie Evans, David Kaiser

Journal of Undergraduate Research

A greater incidence of ACL injuries in women compared to men may stem from complex, interrelated factors, including hamstring-quadriceps strength imbalances, joint laxity, and neuromuscular deficits. While congenital joint laxity cannot be reversed, both hamstring/quadriceps imbalances and neuromuscular deficits have been shown to improve with functional neuromuscular training.1,2,3 Consequently, research needs to be conducted to quantitatively measure the changes to hamstring/quadriceps strength ratio as a result of neuromuscular functional training.

The Effects Of Multi-Modal Training In Athletes, William Brodegard, Dr. Roy Pat Vehrs

Journal of Undergraduate Research

In early March of last year I was suffered a stress injury from riding a bicycle. I had been training heavily, and was forced to stop training to allow my body to heal. During my time off of the bike, I stayed in shape by running and swimming. When I returned to the bicycle, I found that my level of fitness and biking ability had not depreciated as much as I had thought it might. Cross training had proven effective in maintaining my cycling skill level. I decided to research how cross training and cycling specific training effect the ability …

School Gardens, David W. Hey

Kinesiology and Public Health

School gardens can have great promise as they can positively impact children's food choices by improving their preferences for vegetables, increasing their nutrition knowledge, and prevent nutritionally related diseases (i.e., diabetes and obesity). In their natural state, fruits and vegetables have high water and fiber content and are low in calories and energy density. Additionally, it has been demonstrated that the use of a garden as part of an outdoor environmental studies program can have a beneficial impact on performance of standardized achievement tests, as well as attention and enthusiasm for learning in school children.

In June of 2004, national …

Dip-Wrap Paraffin Wax And Moist Heat Pack Application And The Subsequent Rise In Tissue Temperatures, Jared K. Wilson, Dr. Kenneth L. Knight

Journal of Undergraduate Research

Paraffin wax baths are used by athletic trainers and physical therapists to apply superficial heat to the extremities of patients. The National Athletic Trainers Association (NATA) includes the use of paraffin wax as a required competency for students who are working toward certification. While the general consensus of many athletic trainers and textbooks1,2,3 is that paraffin wax application is an effective superficial heating modality, data is not available to back up such opinions. Not enough research has been done to quantify its heating effects or to compare it to other superficial heating modalities.

(1997), Sherry et al. (2004), Willy et al. (2001)). The purpose of this study was to determine which method of total time and dosage was most effective in increasing the range of motion and flexibility of the hamstring muscle.

A Biomechanical Evaluation Of A Novel Mobile Walking Device, Thomas D. Bateman, Dr. Matthew K. Seeley

Journal of Undergraduate Research

Many individuals rely on crutches to help them walk. Those relying on traditional crutches often suffer from upper-extremity pathologies as well as psychological detriments.1 Additionally, those using crutches typically suffer from increased energy expenditures during locomotion.2 The Millennial Crutch (Figure 1) is a proposed alternative to the traditional crutch. The producers of the Millennial Crutch purport that Millennial Crutch use eliminates many of the disadvantages of traditional crutch use.

Functional Morphology Of Rat Hands And Feet: Correlation With The Ability To Grip Tree Branches During Locomotion, Jessica E. Fonce, Andrew R. Lammers

Undergraduate Research Posters 2013

Anatomy and function are usually closely related. Since locomotion on tree branches is common among mammals, we expect to find that the anatomy of the hands and feet is well-suited toward gripping narrow, cylindrical, branch-like substrates. We hypothesize that the ability of rats to grip arboreal supports relies on musculature responsible for adducting the first digit (thumb and big toe) and opposing medial-most and lateral-most digits. We dissected the hands and feet of four rat cadavers. There is a substantial muscle that may be responsible for the flexion/adduction of the thumb in the hands. We also found lumbricals, and dorsal …

Faculty Research and Creative Activity

The purpose of this study was to investigate the influence of exercise order on one-repetition maximum (1-RM) and ten-repetition maximum (10-RM) strength gains after 6 weeks of resistance training (RT) in trained men. Sixteen men were randomly assigned into two groups based on the order of exercises performed during training sessions: a group that performed large muscle group exercises first and progressed to small muscle group exercises (LG-SM); while a second group performed the opposite sequence and started with small muscle group exercises and progressed to large muscle group exercises (SM-LG). Four sessions of RT were conducted per week; all …

Center Of Pressure And The Projection Of The Time-Course Of Sitting Skill Acquisition, Joshua L. Haworth, Regina T. Harbourne, Srikant Vallabhajosula, Nikolaos Stergiou

Journal Articles

A normal time-course for the acquisition of sitting is essential. A delay in sitting may affect other developmental milestones, resulting in deficiencies in overall skill. Therefore, our aim was to identify variables whose measures at the very beginning of sitting would allow for the projection of the evolution of the sitting skill. Center of pressure data were collected from the postural sway of twenty-six typically developing infants while sitting on a force platform with a beginning ability to sit upright. Spatial, temporal and frequency variables of postural sway were obtained from both the medial/lateral and anterior/posterior directions of sway. Discriminant …

Promoting Weight Loss Before Pregnancy: Feasible Or Futile?, Suzanne Phelan, Todd Hagobian, Anna Brannen, Ana Stewart, Brianna Schmid, Leonard Cedars

Kinesiology and Public Health

Pre-pregnancy obesity is a well-established risk factor for several adverse maternal and fetal outcomes, including gestational diabetes, hypertension, cesarean sections, and fetal macrosomia. Weight loss before pregnancy could help prevent such complications, but the feasibility of such an approach remains unknown. The current study examined the feasibility of a 3-month pre-pregnancy behavioral weight loss program in 12 overweight/obese women planning pregnancy. The 3 month program resulted in an average 5.4 ± 3.0 kg weight loss and significant improvements in self-monitoring, physical activity, eating and exercise self-efficacy, and healthy eating (p < 0.04). By the end of the 9 month follow-up, half of sample (n = 6) had conceived. Women reported significant increases in weekly or more frequent self-weighing (p < 0.0001), counting calories (p < 0.001), consuming fruit and vegetables (p = 0.007), and cutting out fat (p = 0.0001) and junk foods (p = 0.002). A lifestyle modification program to promote weight loss before pregnancy promoted clinically significant weight loss and appeared feasible.

Chronic Ankle Instability And Lower Extremity Joint Absorption, Heather Mcdonald Nope, Ty Hopkins, Matt Gage

Journal of Undergraduate Research

Nearly everyone involved in sports has witnessed or experienced an ankle injury. Often these primary injuries lead to secondary knee or hip pain. The purpose of this study was to learn more about how the body reacts to ankle injuries, in regard to absorbing energy in joints. The hypothesis states that subjects with chronic ankle instability will absorb more energy in the knee and hip. Conversely, subjects without chronic ankle instability will absorb more energy in the ankle.

Increasing Electrical Stimulation Frequency Above Cramp Threshold Frequency Increases The Strength And Duration Of Electrically-Induced Muscle Cramps, Steven Wilding, Dr. Kenneth Knight

Journal of Undergraduate Research

Muscle cramps are the most common heat-related illness experienced by athletes (Cooper et al, Journal of Athletic Training, 2006, 41, 332-336). Muscle cramps also occur frequently at night (“night cramps”) and in the elderly. Because the cause of muscle cramps is unknown, our treatments for them are often times unsuccessful. In fact, less than 50% of athletic trainers felt they were very successful in treating muscle cramps (Stone et al, J Sport Rehab, 2003, 333-342).

Exercise Intensity And Cytoskeletal Protein In Rats, Brett Noble, Dr. Allen Parcell

Journal of Undergraduate Research

Research in the field of exercise science, as in any scientific field, is changing and developing as knowledge of each intricate part of the human organism grows. Unfortunately such understanding can only be developed through tedious, ongoing research in labs. Comparative to other scientific fields, the study of exercise physiology, particularly that of the structural proteins in skeletal muscle, is relatively new. There is still much to be learned and studied. The data which we gathered contributed to the ever growing body of information that helps us better understand how skeletal muscle functions.

Upper Extremity Functional Dexterity Changes Due To Neck Extensor Or Forearm Muscle Fatigue, Rachel Sommerfeldt, Dr. A. Wayne Johnson

Journal of Undergraduate Research

Neck pain and headaches related to neck pain will affect an estimated two thirds of the population at some time during their life. The pain may be caused by high-intensity exertion, such as whiplash, or from prolonged low-intensity exertion. An accepted explanation for neck pain is fatigue of the neck muscles caused by the sustained contraction which is required to hold the head in position. Studies suggest that a significant reduction of muscle function is a result of long term neck fatigue. Thus, an individual suffering from neck pain may have reduced muscle function, limiting activity and requiring changes in …

A Comparison Of Various Contraction Intensities In Contract-Relax Proprioceptive Neuromuscular Facilitation Stretching Of The Hamstring Muscle Group, Heather Nielson, Dr. Brent Feland

Journal of Undergraduate Research

Proprioceptive neuromuscular facilitation (PNF) is a popular stretching method that increases flexibility. There are several different methods of PNF, but they all usually require the assistance of another person. The contract-relax method is a widely used PNF techniquei that utilizes maximum voluntary isometric muscle contraction (MVIC) followed by relaxation. An athletic trainer or therapist then pushes the relaxed muscle further into stretch after each contraction. So, traditionally the person is asked to contract the muscle being stretched as hard as possible in order to produce the MVIC. Very little research has been conducted to using submaximal contractions.ii iii Therefore, the …
