EFFECTS OF ONE-HOUR ROAD RUNNING AND SHOE ON TIBIAL ACCELERATIONS IN RECREATIONAL RUNNERS
Get PDFThe purpose of this study was twofold. Firstly, we evaluated the effect of one-hour running on tibial acceleration parameters. Secondly, we determined whether the shoe fatigue after one-hour running would influence these tibial acceleration parameters. Ten runners ran at a constant preferred speed with a standard running shoe. They also ran one bout of 5 min with another identical but fresh running shoe before and after the one-hour run. Tibial acceleration amplitudes and wavelet analyses demonstrated a significant reduction of the tibial impact parameters after one-hour running, but no significant shoe effect. These reductions could be attributable to the slight increase in stride frequency from the beginning to the end of the one-hour running. Noteworthy, the tibial acceleration reduction was observable along the anteroposterior axis, not along the vertical axis. Considering the tibial acceleration as a potential risk factor for developing running-related injuries, these parameters did not change in a harmful way after one-hour of running at the preferred running speed. The shoe modification during the one-hour run did not seem to influence running biomechanics
DOES CRICKET FAST BOWLING LUMBAR SPINE KINEMATICS CONTRIBUTE TO LUMBAR BONE STRESS INJURY?
Get PDFLumbar bone stress injuries (LBSI) have the highest prevalence of any injury in cricket. The purpose of this study was to determine differences in lumbar spine kinematics between fast bowlers who avoid LBSI and those who sustain LBSI. 45 elite male fast bowlers completed 6 maximum effort deliveries captured by a motion analysis system. Upper and lower lumbar spine joint angles were reported at key instances and compared between groups. MRI and medical records revealed current and future incidence of LBSI. 47% of fast bowlers were diagnosed with LBSI. While no statistically significant differences in lumbar spine joint angles between groups were observed, LBSI cases demonstrated non-statistically significantly greater upper lumbar spine extension at BFC, FFC and maximal value which warrants further investigation
THE EFFECT OF SUBMAXIMAL LOADS ON TRUNK POSTURE DURING THE CLEAN IN COMPETITIVE WEIGHTLIFTERS
Get PDFThe purpose of this study was to investigate the effect of submaximal loads on trunk posture during the clean in the aid of improving the technical and physical training of weightlifters. Weightlifters (n=10) with at least two years of training experience in weightlifting participated the study. Each participant performed 3 cleans at 65, 75, 85% of one repetition maximum (1RM). The results of this study highlighted the importance of a controlled trunk motion during the first pull followed by a maximal extension of the trunk in the second pull in relation to weightlifting performance. This study provided novel information about important technical aspects in weightlifting
PRINCIPAL COMPONENT ANALYSIS OF KICKING KINEMATICS IN MALE AND FEMALE SOCCER PLAYERS
Get PDFThis paper aimed to compare the angular motion in the sagittal plane of the hip and knee in male and female soccer players during the entire kicking cycle through principal component analysis (PCA). Kicking kinematics were recorded for 43 soccer players with a motion capture system. The kicking cycle was defined from toe off to the end of follow through and time-normalised hip and knee joint angles data were used as input to PCA. Four PC were extracted for hip and knee joint angles. Multivariate tests suggested an overall significant difference in the PC scores between females and males for hip flexion data (p = 0.001) but not for knee flexion data (p = 0.060). The results suggest that the primary difference in joint angle patterns between females and males occur at the hip joint. More specifically, females tend to exhibit smaller hip extension motion than their male counter-pair during the backswing phase (during the first 20% of the kicking cycle)
THE RELATIONSHIP BETWEEN WOODLAND CARIBOU, SOIL CARBON CYCLING AND SOIL FERTILITY ON THE SLATE ISLANDS ARCHIPELAGO IN ONTARIO, CANADA
Get PDFI investigated biogeochemical connections between woodland caribou (Rangifer tarandus caribou) herbivory, vegetation, soil fertility, and soil carbon cycling on the Slate Islands Provincial Park in Ontario, Canada. Woodland caribou are threatened in Ontario, and the caribou population on the Slate Islands has declined steeply since 2015. Northern Michigan University (NMU) and Ontario Ministry of Natural Resources and Forestry (OMNRF) ecologists established caribou and snowshoe hare (Lepus americanus) exclosures on the islands in 2006, and have routinely monitored the vegetation to study the effects of limiting herbivory.
This study explores the implications of limiting herbivory on soil fertility, carbon and nitrogen stocks, and CO2 respiration by using NMU/OMNRF exclosures. Spatial variability in soils is a major source of variation and was accounted for in the study design, which consisted of three sets of three co-located, randomized (3.65 x 3.65 m) control plots, caribou/snowshoe hare exclosures, and caribou-only exclosures. Significantly larger levels of soil phosphorus (ppm), CEC (meq 100 g-1), C:N ratios; soil CO2 (g m-2 d-1) respiration; total carbon stocks (Mg C ha -1), and total nitrogen stocks (Mg N ha -1) were detected in reference soils without at least 100 years of caribou herbivory pressures on a contained island ecosystem. After 12 years of exclosure, vegetation strongly recovered, but soil did not recover in that time frame
Junkballer
Get PDFAt seventeen Roger Fishinger’s a pretty good pitcher. But his older brother Bob’s a pitcher, too—and a once-in-a-generation type talented pitcher, with Big Leagues written all over him. The way Roger sees it, the only way to make up some ground in this probably unwinnable sibling rivalry is to start by getting a Division One scholarship. That, and nothing less. Junkballer is a short novel told from the perspective of Roger over the course of his junior-to-senior year summer as he tries achieving this goal, while navigating the world of youth travel baseball and all its quirks. The pushover coaches, prescription drug abuse, kleptomaniac teammates, heat-stroke, and mosquitos the size of hummingbirds
Survivor’s Guilt and the Ethics of Remembering in Isaac Bashevis Singer\u27s The Slave and Cynthia Ozick’s “The Shawl”
Get PDFThe focus of this thesis is an analysis of post-Holocaust Jewish-American literature with a specific emphasis on texts set in Europe. In particular, I examine how Jewish-American authors who lived in the United States during the Holocaust address issues of trauma and survivor’s guilt through fiction. Informed especially by Theodor Adorno and Elie Wiesel, I examine the ethics of fictionalizing the Holocaust. Furthermore, this thesis considers both trauma theory and the psychology of grief to investigate the ways in which the Jewish-American community at large responded to the cultural destruction perpetrated by the Nazis during the Holocaust. Chapter One analyzes the use of allegory in Isaac Bashevis Singer’s The Slave, a novel set in seventeenth-century Poland. In writing The Slave, Bashevis Singer approaches issues of guilt and the destruction of cultural and religious spaces, as well as the loss of community, in such a way as to give specific voice to the Jewish American community. In Chapter Two, I focus on Cynthia Ozick’s short story “The Shawl,” which is a brief but powerful fictional Holocaust narrative. Ozick’s text examines the ways in which the Holocaust destroys the bonds of family and community, and it grapples with the question of responsibility and blame felt by those who were not directly affected by the Holocaust itself
The Female Leadership Experience in Pre-Professional and Professional Ballet
Get PDFABSTRACT
THE FEMALE LEADERSHIP EXPERIENCE IN PRE-PROFESSIONAL AND PROFESSIONAL BALLET
By
Jill Grundstrom
The purpose of this qualitative, narrative research study was to explore the experiences of current female leaders in pre-professional and professional ballet. These stories often remain untold, as leadership in ballet has been largely male-dominated. The study examined the stories of four female leaders in ballet, including their journey to leadership, leadership philosophy and protocol, and thoughts regarding the future of female leadership in ballet. This study collected data using in-person, phone, and email interviews. The collected data was analyzed and coded for themes and conclusions using deductive and inductive approaches.
From the data, four conclusions emerged. First, it was determined that a particular training was common among the participants and directly influenced their career development. Second, similar female leadership philosophies, qualities and traits were recognized, indicating that a successful leadership protocol could be identified from the data. Third, extensive leadership responsibilities were prevalent in each participant’s story. Fourth, the significance of mentorship was acknowledged; the participants both having and being strong mentors
Crossroads
Get PDFMy thesis is a collection of nonfiction narrative essays that explore my relationship with fear: where it comes from, how it affects me, and how to move forward in life despite its sometimes crippling effects. My thesis also takes into consideration the ramifications of inherited trauma and how such shared family history--passed on through the blood or by the stories we share--provides a framework for analyzing my own fear. Like my title essay “Crossroads” implies, I find myself at a pivotal moment in my life--a fork in the road, if you will--and my thesis is an attempt to make a decision about my future by examining my current frustrations and also my past--in particular the moments and experiences in which I found the courage to move beyond fear. My thesis also takes into account how travel and travel literature, with their ability to take one outside one\u27s normal life or experience, can offer perspective and, in the case of actual travel, the opportunity to take risks and grow beyond the limits we all too often place on ourselves
