The mechanical behavior of tendons has been well studied in vitro. A noninvasive method to acquire mechanical data would be highly beneficial. Elastography has been a promising method of gathering in vivo tissue mechanical behavior, but it has inherent limitations. This study presents acoustoelasticity as an alternative ultrasound-based method of measuring tendon stress and strain by reporting a relationship between ultrasonic echo intensity (B-mode ultrasound image brightness) and mechanical behavior of tendon in vitro. Porcine digital flexor tendons were cyclically loaded in a mechanical testing system while an ultrasonic echo response was recorded. We report that echo intensity …

Despite a complex cascade of cellular events to reconstruct damaged extracellular matrix (ECM), ligament healing results in a mechanically inferior, scar-like tissue. During normal healing, the number of macrophages significantly increases within the wound site. Then, granulation tissue expands into any residual, normal ligamentous tissue (creeping substitution), resulting in a larger region of healing, greater mechanical compromise, and an inefficient repair process. To study the effects of macrophages on the repair process, bilateral, surgical rupture of their medial collateral ligaments (MCLs) was done on rats. Treatment animals received liposome-encapsulated clodronate, 2 days before rupture to ablate phagocytosing macrophages. Ligaments were …

Psychology Of Sport Injury : A Holistic Approach To Rehabilitating The Injured Athlete, Jennifer Jordan Utley
Athletic Training Collection
Sports medicine practitioners must consider both physical and mental aspects of injury to fully rehabilitate the injured athlete. The psychological distress that follows injury has been well documented and calls for a change in the rehabilitation of injured athletes.1-3 With the recent emergence of sport psychology and the emphasis on competitive sport in the United States and beyond, psychological skills are no longer solely utilized by the elite athlete; college and high school athletes are gaining instruction in the use of psychological skills from sport psychologists, coaches, and fellow teammates. Psychological skills have been shown to be effective in …

Turf Or Grass? Comparison Of Rates And Causes Of Anterior Cruciate Ligament (Acl) And Medial Collateral Ligament (Mcl) Injuries On Field Turf And Natural Grass Football Fields Of A Division Iii School, Thomas Michael Mcknight
Undergraduate University Honors Capstones
The mixed methods study will compare the rates and causes of anterior cruciate ligament and medial collateral ligament injuries on Field Turf and natural grass football fields of a NCAA Division III school. This study offers evidence for the safety of the different playing surfaces and risk to the players. This pilot study finds also evidence that there is no statistical significance between knee injuries and the playing fields. The qualitative and quantitative data are inconclusive and require further study to reach a conclusion.

Conceptually, it is important to understand the underlying physiological mechanisms of any training program model. This understanding aids the coach/sport scientist in making better choices in manipulating variables in formulating the training model. These underlying mechanisms can be associated with training variable manipulation and fatigue management aspects as well as the overall health of the athlete. Hormone and cytokine concentrations can be linked to alterations resulting from the manipulation of training variables and to subsequent alterations in performance (Haff et al., 2008; Ishigaki et al., 2005; Jurimae et al., 2010; Stone et al., 2007). For example, alterations in the testosterone: …
