Effect Of Pre-Exercise Ice Slurry Ingestion On Physiological And Perceptual Measures In Athletes With Spinal Cord Injuries, Alexis Moore, Kelly Pritchett, Robert C. Pritchett, Elizabeth Broad

International Journal of Exercise Science

International Journal of Exercise Science 14(2): 19-32, 2021. Athletes with cervical level spinal cord injuries (SCI) have an impaired ability to thermoregulate during exercise, leading to an increased core temperature (T_core) due to a decrease in sweat response. Elevated T_core may result in premature onset of fatigue and decreased athletic performance. Therefore, precooling techniques that decrease T_core before exercise may increase the storage capacity for metabolic heat production, thereby delaying the time before reaching a critically high T_core. The purpose of this study was to investigate the effects of pre-exercise ice slurry ingestion …

Therefore, a rehabilitation program to manage or treat scapular dyskinesis is important. The effectiveness of feedback modalities used in combination with exercise may be more beneficial in treating and or managing scapular dyskinesis versus just exercise alone. Purpose: In overhead athletes with scapular dyskinesis, does the use of an exercise program with biofeedback (taping, visual, verbal, surface EMG, video, tactile cueing, and conscious control) reduce the risk of shoulder injury versus exercise alone? Results: Seventeen peer-reviewed articles were examined utilizing …

Does Implementing Neck Strengthening Exercises Reduce The Risk Of Concussion?, Brandon M. Desrosiers

All Electronic Theses and Dissertations

Background: There is currently no standard process or preventative method to reduce the risk of concussions. Researchers have claimed that new helmet technology, q-collar necklace, and mouthguards can reduce concussions, but the evidence is lacking. Neck strength is emerging as a possible preventative method to help athletes decrease the likelihood of sustaining a concussion. The theory suggests that individuals with stronger neck muscles will engage their cervical muscles during a collision, reducing the deceleration of the head. Purpose: The purpose of this paper is to answer the clinical question, does implementing neck strengthening exercises into an athlete’s workout program reduce …

Use Of Platelet-Rich Plasma Injections For Treatment In Patients Diagnosed With Achilles Tendinopathy, Nicole M. Pearson

All Electronic Theses and Dissertations

Background: Achilles tendinopathies are common among individuals who are active, usually participating in a sport with a high volume of repetitive motion. Historically, these injuries have been treated with conservative home exercises. If the patient exhausts their conservative treatment options, the next step is typically surgery to repair the tendon (Maffulli, 2015). Recently, platelet-rich plasma (PRP) injections have become more commonly used to treat musculoskeletal injuries and are considered minimally invasive procedures. This allows the patient to return home immediately post injection and return to activity within a few days. However, the research shows mixed results in terms of its …
