The Effect Of Acute And Chronic Thermotherapy On Type 2 Diabetic Skeletal Muscle Cell Viability And Gene Expression: Pilot Study, Louay Bachnak, Jean Sparks, Xavier F. Gonzales, Daniel Newmire, Felix Omoruyi Feb 2020

The Effect Of Acute And Chronic Thermotherapy On Type 2 Diabetic Skeletal Muscle Cell Viability And Gene Expression: Pilot Study, Louay Bachnak, Jean Sparks, Xavier F. Gonzales, Daniel Newmire, Felix Omoruyi

International Journal of Exercise Science: Conference Proceedings

Diabetes is a chronic metabolic disease affecting millions of people globally. Type 2 diabetes is associated with insulin resistance or a defective secretion of insulin from the pancreas. The skeletal muscle system accounts for 80% of glucose uptake and is a vital player in healthy aging and muscle mass maintenance. PURPOSE: The purpose of this study was to investigate the effects of thermotherapy on gene expression and cell viability in Type 2 Diabetic skeletal muscle. METHODS: Human skeletal muscle myoblast (HSMM) and Diabetic Type 2 human skeletal muscle myoblast (D-HSMM) (Lonza Inc, Walkersville, MD) were cultured until 90% confluency was, …


The Effects Of Mild Dehydration On Cycling Performance In The Heat, Elika Hamer May 2018

The Effects Of Mild Dehydration On Cycling Performance In The Heat, Elika Hamer

Health, Human Performance and Recreation Undergraduate Honors Theses

Abstract

Introduction: Hypohydration exceeding 2% of body mass (bm), affected by heat and thirst level, leads to decreased athletic performance. Both physiological and psychological factors of dehydration have an impact on an athlete’s perceived performance. However, it is unclear whether the effects of psychological, physiological, or both have a negative impact on athletic performance caused by mild hypohydration. Purpose: The purpose of this study was to determine if mild hypohydration affects exercise performance in trained cyclists while blinding their hydration state. Methodology: Eleven competitive male cyclists participated in two blinded experimental trials, hypohydrated and euhydrated states by intra-venous infusions. The …


Effect Of Fluid Temperature And Volume On Thermoregulation In The Heat, Michelle M. Johannsen Jan 2016

Effect Of Fluid Temperature And Volume On Thermoregulation In The Heat, Michelle M. Johannsen

Graduate Student Theses, Dissertations, & Professional Papers

The link between thermoregulation, hydration status, and exercise performance in hot humid environments is controversial. The purpose of this study was to evaluate the effects of volume and temperature of ingested fluid on hydration status, thermoregulation and exercise performance. Recreationally active males (N=11, 24.7±5.9 years; VO2max=58.2±6.0 mL/kg/min) completed two 3-hour intermittent exercise trials in the heat (31o WBGT=35.5°C with 50% humidity). Participants consumed either 1 mL/kg body weight (BW) of room temperature water (35.5°C; ROOM) or 0.5 mL/kg of an ice slurry mixture (~0°C; COLD) every ten minutes throughout the trials in a randomized crossover design. Subjects …
