BACKGROUND: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising …

The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius
Research outputs 2014 to 2021
This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …
Noncontact Anterior Cruciate Ligament Injuries In Collegiate Female Soccer Players: The Effects Of A Four-Week Prevention Program On Landing Kinematics, Tess K. Marcordes
Noncontact Anterior Cruciate Ligament Injuries In Collegiate Female Soccer Players: The Effects Of A Four-Week Prevention Program On Landing Kinematics, Tess K. Marcordes
ELAIA
Background Noncontact anterior cruciate ligament (ACL) injuries are highly prevalent in soccer as quick changes in direction, stop-start motions, as well as jumping and landing often paired with shooting or passing a ball, are occurring continuously throughout a practice or match. Exaggeration of these movements with extreme joint motions increases the likelihood of ACL injury. An ACL injury can be detrimental to an athlete’s career, as 25% of athletes with such injuries do not return to their pre-injury level of play (Padua, DiStefano, Beutler, de la Motte, DiStefano, and Marshall, 2015). Myer, Ford, McLean, and Hewitt (2006), Garcia (2011), and …

The Relationship Of Force-Time Variables Between The Loaded Squat Jump And The Midthigh Block Clean Pull, Hannah Marie Macke
The Relationship Of Force-Time Variables Between The Loaded Squat Jump And The Midthigh Block Clean Pull, Hannah Marie Macke
Theses and Dissertations from 2018
Loaded squat jumps and midthigh block clean pulls are exercises that can be used in a strength and conditioning program to increase lower-body power. Lower-body power is critical in jumping, sprinting, and other sport specific movements. Intensities of 45-pound barbell, 20%, 40%, and 60% of a high-force, low-velocity movement were used to assess the force-time variables of the loaded squat jump and midthigh block clean pull. The current study compared peak power output as well as peak barbell velocity to find which exercise and intensity combination would be most beneficial for an athlete to increase lower-body power. A linear position …

Creating Change In Intercollegiate Athletics: The Sexual Assault Prevention Paradigm For Athletic Departments, Kristy Mccray, Sue Sutherland, Donna L. Pastore
Health and Sport Sciences Faculty Scholarship
In 2011, the Office for Civil Rights issued a “Dear Colleague Letter” instructing universities to take action regarding sexual assault on college campuses. Specifically, universities must better educate students on the prevention of sexual assault, in the hope of reducing violence against women. Previous research is inconclusive on the involvement of intercollegiate student-athletes in incidences of sexual assault; however, recent high-profile cases of sexual misconduct at universities indicate that student-athletes are not immune to this issue. The purpose of this study was to explore how sexual assault is viewed within the culture of intercollegiate athletics, including education, occurrence, and prevention. …

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer
International Journal of Aquatic Research and Education
According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to …

Case
We present the case of a thirteen-year-old female who sustained a posterior wall acetabular fracture dislocation. She underwent urgent closed reduction and subsequent uncomplicated open reduction and internal fixation. Post reduction computed tomography demonstrated a concentrically reduced hip joint with no evidence of femoroacetabular impingement (FAI). She subsequently healed her fracture and returned to running activities; however, one year later presented with aching pain in her thigh. Radiographs demonstrated the development of a large osseous prominence on her anterolateral femoral neck consistent with femoroacetabular impingement. Based on these findings she was evaluated by a hip preservation specialist. She subsequently …

The Effects Of Stress On American Football Overhand Throw Accuracy, Cale Anderson
All NMU Master's Theses
The American overhand football throw is a highly scrutinized position because of all the different kinds of stress both physical and psychological that are put onto those players. The current study sought to develop a formula using psycho-emotional and physical variables to predict the performance of an American overhand football throw under stressful/non-stress situations. Participants were tested on two days. The stress situation is where tennis balls were thrown, and the subject did not know where they were going to throw. The non-stressed was a 3 step drop without knowing what target they were throwing at and these conditions were …
Biomechanical Adaptations To An Implemented Ramp Angle In Recreational Alpine Skiers, Stephanie R. Moore
Biomechanical Adaptations To An Implemented Ramp Angle In Recreational Alpine Skiers, Stephanie R. Moore
All NMU Master's Theses
Most ski boot-binding complexes have a negative ramp angle. This angle is not regulated or reported in the alpine ski industry, but may influence skier balance and pressure control. Thus, joint coordination and center of pressure maintenance in alpine skiers (n = 19) was investigated during simulated ski squat and balance tasks with increasing binding ramp angles (0°, 1°, 2°). Greater sagittal plane center of pressure excursions were observed with ski-booted tasks compared to barefoot conditions during squats and balance simulations. Squat tasks performed on skis resulted in more uncoordinated knee-ankle movement, however, this effect was reduced with the highest …

Comparisons Between Movement Onset Identification Methods Used In Isometric Mid-Thigh Pull Test, Junshi Liu
Electronic Theses and Dissertations
This dissertation aimed to explore the usefulness of using force derivatives for onset detection in the isometric mid-thigh pull test. First, we examined applications of three differential calculus principles, first and second derivative, and curvature using visual detection as a reference under different baseline conditions. Second, we compared the best derivative method to a threshold-based method using visual detection as a reference. Results of our first investigation showed trivial differences between many differential calculus methods and visual detection. However, statistical differences exceeding a trivial effect was observed when instantaneous force and rate of force develop were examined. Through the first …

BACKGROUND: In muscular dystrophy and old age, skeletal muscle repair is compromised leading to fibrosis and fatty tissue accumulation. Therefore, therapies that protect skeletal muscle or enhance repair would be valuable medical treatments. Hypoxia-inducible factors (HIFs) regulate gene transcription under conditions of low oxygen, and HIF target genes EPO and VEGF have been associated with muscle protection and repair. We tested the importance of HIF activation following skeletal muscle injury, in both a murine model and human volunteers, using prolyl hydroxylase inhibitors that stabilize and activate HIF.
METHODS: Using a mouse eccentric limb injury model, we characterized the protective effects …

Targeted Exercise Therapy To Enhance Neural Activation, Terence Moriarty, Kelsey Bourbeau, Bryanne Bellovary, Micah Zuhl
Shared Knowledge Conference
Various types of exercise therapies, have been implemented into treatment for those suffering from psychological disorders and traumatic brain injury. The prefrontal cortex (PFC), which houses key cognitive constructs is responsive to exercise, and is commonly measured using functional near infrared spectroscopy (fNIRS). Evidence suggests that exercise mediates neural adaptation through increased blood flow and neurogenesis, which enhances neural activation leading to improved cognitive performance. However, the intensity of exercise that has the most robust impact on brain blood flow is currently unknown. Purpose. Therefore, the primary aim of the study is to compare PFC activation during cognitive tasks performed …

Objective-This study aims to identify the relationship between the Fifa 11+ program and the angle of valgus deformity at the knee. Background-200,000 ACL tears are reported each year. Previous studies have linked valgus motion of the knee to an increased rate of ACL injury and females exhibit a 4-6x increased risk for ACL injury. Fifa 11+ has shown promise in studies done on professional soccer teams yet remains untested in a younger population. Methods-This prospective cohort study of 300 consented female soccer players will use Noraxon as a tool for the measurement of valgus angle at the …

The purpose of this analysis was to construct a preliminary scale of reference values for reactive strength index-modified (RSImod). Countermovement jump data from 151 National Collegiate Athletic Association (NCAA) Division I collegiate athletes (male n = 76; female n = 75) were analyzed. Using percentiles, scales for both male and female samples were constructed. For further analysis, athletes were separated into four performance groups based on RSImod and comparisons of jump height (JH), and time to takeoff (TTT) were performed. RSImod values ranged from 0.208 to 0.704 and 0.135 to 0.553 in males and females, respectively. Males had greater RSImod …
