COUNTERMOVEMENT JUMP VARIABLES AND ESTIMATED PEAK POWER IN FEMALE CHILDREN WITH DYNAMIC KNEE VALGUS
Get PDFThe purpose of the current study was to evaluate countermovement jump biomechanical variables and to estimate peak power using different approaches in female children with dynamic knee valgus. Twenty-six female children, aged 10-14, with dynamic knee valgus were recruited. A Kistler force plate was used to record the kinetic data during three CMJ trials. Less peak power (estimated using allometric method) and greater landing force during countermovement jump were significantly correlated with valgus angle in female children (P= 0.033, R= -0.419, and P= 0.0.43, R= 0.413, respectively). Estimated peak power results using Sayers and Harman methods were significantly different from actual peak power outcomes (P=0.042, P=0.027 respectively). Greater landing force and decreased peak power during CMJ showed to be correlated with increased valgus angle in female children. Additionally, the allometric method seemed to be more accurate for estimating peak power compared to other methods
BREASTS BIOMECHANICS; FROM RESEARCH TO ENTERPRISE TO INDUSTRY TO CONSUMER
Get PDFThe purpose of this initiative was to use published breast biomechanics methods to develop a bra testing service which steamlined funder engagement, generated income and research data. Following the set up of the Bra Testing Unit (2014), testing packages were sold which establish sports bra performance. To do this, appropriately sized volunteers (n=3,612) were recruited to run bare-breasted and in various sports bras (n=301). Breast movement reduction (% support) and subjective measures, were collected and sports bra support compared across all bras tested. This initiative has streamlined engagement, generated income through 48 package sales to 25 companies worldwide (start-ups to global brands) and is self-sustaining, supporting a biomechanics researcher and offering student opportunities. The data have informed publications; supporting impact case studies. This initiative commercialises, industrialises and consumerises biomechanics research
THE INFLUENCE OF CYCLISTS’ COMPETITIVE LEVEL AND EXERCISE INTENSITY ON CRANK TORQUE VARIABILITY DURING PEDALLING
Get PDFThe purpose of this study was to analyse the influence of competitive level and pedalling intensity on crank torque variability. Seventy-two cyclists (Club, Elite, Professional) pedalled at 200, 250 and 300 W on a cycle ergometer that recorded crank torque. Multiple-trial variability (average standard deviation) and complexity (Sample Entropy) analyses were applied. Both competitive level and pedalling intensity showed a significant effect on Sample Entropy values of crank torque, with a significant interaction between the two factors, while average standard deviation was only affected by pedalling intensity. In conclusion, pedalling intensity had an effect on both crank torque multiple-trial variability and complexity, while the last has shown a bigger potential for fine discrimination between performance levels in cyclists

Indian Country and Law Enforcement: A Review of Current Literature
No full textTribal Nations hold an unparalleled position relating to their status as domestic-dependent sovereigns, possessing the ability to self-govern their nation within another nation. This legal-political identity creates a distinctiveness regarding jurisdiction and authority around tribal citizens and non-citizens within the reservation. Based on scholar Eve Tuck’s Suspending Damage article, featured in the Harvard Educational Review, I will seek to locate desire-centered traits in the current literature regarding the relationship between law enforcement and Indian Country; Tuck’s methodology is a subsequent shift from the more frequently utilized damage-centered perspective. Over the last five years, movements such as Standing Rock and Black Lives Matter have created a national calling for social justice reform and action by defunding the police, halting oil pipeline operations within Tribal lands, and sweeping policy change. These actions against the forced installation of the Dakota Access Pipeline on the Standing Rock Sioux Indian Reservation and attention to racially motivated violence and police brutality faced by African-American individuals have begun to cause society to become more aware of the presence and impacts that oppressive and authoritative structures harbor. Historical moments and scholarly works such as these prompt a broader series of questions regarding the relationship between Indian country and law enforcement and the structures of authority within those entities
Determining Performance of the SD Biosensor Rapid Test for Covid-19 Antibodies as a Point of Care Test in an Urgent Care Setting
No full textDuring early stages of the Covid-19 pandemic, it was understood that individuals in high exposure occupations would be at greater risk of infection. At this stage, PCR testing was limited to individuals with mild/moderate acute respiratory symptoms. Due to the possibility of asymptomatic cases among healthcare workers and law enforcement officers, AMD Urgent Care of Swartz Creek, MI obtained rapid immunochromatography SARS-CoV-2 antibody tests (SDS Biosensor Standard Q Covid-19 IgM/IgG Duo Test kit). This study had two aims. First, to determine potential cross reactivity to non-Covid-19 seasonal coronaviruses in the region. Second, to analyze agreement between antibody tests and PCR tests. False-positive results due to cross reactivity with non-SARS-CoV-2 coronavirus antibodies were addressed by screening serum samples obtained before prevalence of Covid-19 in the U.S. 56 serum samples were provided by MDHHS and were tested for Covid-19 IgM and IgG antibodies using the same rapid antibody test being used in the clinic. Antibody positive (IgM, IgG, or both) individuals were recommended a PCR test following antibody detection. PCR test results were compared to rapid antibody test results to determine agreement. Separate analyses were conducted for three possible antibody outcomes that would result in a PCR test being administered (IgM+/IgG-, IgM-/IgG+, IgM+/IgG+). Occupational information was collected in a follow-up survey to separate individuals into cohorts based on exposure risk according to OSHA guidelines. SDS Biosensor rapid antibody tests did not indicate a positive result for any pre-pandemic serum samples (0 out of 56). Point of care testing with the rapid test between 4/17/2020 and 6/10/2020 resulted in a positivity rate of 9.99% (188/1882). These rates will be compared to prevalence of non-Covid-19 coronavirus cases in Michigan. Agreement between the positive rapid antibody tests and the subsequent PCR tests was 94%

The Physiological Effects of Therapy Dogs During Exercise for Sedentary Adults
Get PDFPrevious research has shown therapy dogs may be utilized to attenuate heart rate (HR) and blood pressure (BP) responses during various types of stressors due to an increase in oxytocin (OT) and decrease in cortisol (CL) production. These hormonal changes have also been shown to enhance exercise performance. Purpose: This study aimed to determine if physiological responses to exercise changed in the presence of a therapy dog for sedentary adults. Methods: Seven adult subjects (mean age of 30.86 ± 14.07 years) who self-reported less than 150 min of physical activity per week participated in a graded walking test with a constant speed of 2.5 mph in two separate conditions: in the presence of the therapy dog (TD) and alone (CONT). Resting, pre-exercise, and post-exercise HR, BP, and OT concentration measurements were collected. During the exercise test, HR and Ratings of Perceived Exertion (RPE) values were collected each one-min or three-min interval, respectively. Results: The data was analyzed using multiple two-way repeated measures ANOVAs. The results found no significant differences (pConclusions:These results suggest the utilization of therapy dogs is neither beneficial nor detrimental to physiological changes that occur during exercise. This research serves as a beneficial pilot study for the continuation of investigation for this topic
