Determining Skin Temperature Differences Between Three Cold Compression Modalities, Madison S. Mccarthy

Graduate Student Theses, Dissertations, & Professional Papers

Background: Cold and compression are common therapeutic interventions used in the treatment of acute musculoskeletal injuries. Cryotherapy uses extreme cold to decrease cell metabolism and pain following injury. Compression works to decrease overall blood flow and control edema. The benefit of combining cold and compression is to increase the rate and depth of the temperature drop, while utilizing the effects of both modalities. Purpose: The objective of this study was to determine if a crushed ice pack was as effective as newer cold compression technology to decrease skin temperature. A crushed ice pack was compared to the PowerPlay and Game …

Exercise Intensity And Performance Aspects Of Snow Biking Through The Use Of A Fat Bike, Kevin C. Phillips

All NMU Master's Theses

The aim of this study was to quantify, describe, and compare the exercise intensity and performance aspects of riding a fat bike, in a time trial (TT) format, on a natural earthen trail (ET) vs. on a groomed snow trail (ST). Eleven subjects, nine males and two females, participated in this two part study. Heart rate (HR) was used to quantify exercise intensity, examining average heart rate (HR_avg), and peak heart rate (HR_peak). In addition, a global positioning system (GPS) watch was used to assess time to complete the trail, average speed (speed_avg), and …

Pgc-1Α Mediated Muscle Aerobic Adaptations To Exercise, Heat And Cold Exposure, Mohammed Ihsan, Greig Watson, Chris R. Abbiss

Research outputs 2014 to 2021

PGC-1α is regarded as a key regulator of mitochondrial biogenesis due to its central role in regulating the activity of key transcription factors associated with encoding mitochondrial components. Additionally, PGC-1α has shown to mediate adaptations that increase fat metabolism and angiogenesis, contributing to the overall oxidative phenotype of the muscle. While it is well established that exercise is a potent stimulator of PGC-1α, recent evidence indicates that heat and cold exposures may also influence mitochondrial biogenesis through the up-regulation of PGC-1α. This highlights the potential use of these modalities in conjunction with exercise to enhance training adaptations. As such, the …

Short Term Sensory And Vascular Responses To Physical Agent Modalities And Exercise In Healthy Volunteers And Patients With Distal Radius Fracture., Shaguftha Shaik

Electronic Thesis and Dissertation Repository

Currently, there is weak evidence on the effectiveness of different rehabilitation regimens following distal radius fracture (DRF). This thesis evaluated sensory and vascular effects of exercise, thermal and ultrasound interventions that can be used in the mobilization phase (cast removal) after DRF.

Methods

• This thesis includes 3 studies. The first study compared responses to Immersion in Cold water Evaluation (ICE) in the DRF and uninjured hands. Skin blood flow (Sbf), skin temperature (temp.) and sensory perception thresholds (sPT) at 2000Hz for A –beta fibres and at 5 Hz for C fibres were obtained before, immediately after ICE and 10 min …

Exercise-Associated Hyponatremia During Winter Sports, Kristin J. Stuempfle

Health Sciences Faculty Publications

Exercise-associated hyponatremia (EAH) is hyponatremia that occurs greater than or equal to twenty four hours after prolonged physical activity. It is a potentially serious complication of marathons, triathlons, and ultradistance events, and can occur in hot and cold environments Clear evidence indicates that EAH is a dilutional hyponatremia caused by excessive fluid consumption and the inappropriate release of arginine vasopressin. Cerebral and pulmonary edema can cause serious signs and symptoms, including altered mental status, respiratory distress, seizures, coma, and death. Rapid diagnosis and urgent treatment with hypertonic saline is necessary to prevent severe complications or death. Prevention is based on …

The Impact Of Game Outcome On The Well-Being Of Athletes, Marc Jones, David Sheffield

Marc Jones

The present study examined the impact of game outcome on the well-being of athletes. Participants from hockey and soccer teams completed mood and general health questionnaires indicating how they had been feeling over the past few days on three separate occasions. These were four to six days after a win; four to six days after a loss; and over 10 days since the last competition (control period). Differences in well-being were observed following wins, losses, and during the control period. Specifically, athletes reported lower depression and anger after a win compared to a loss, while lower levels of vigour were …
