A Novel Method For Producing Muscle Cramps Without Electrical Stimulation, Elizabeth C. Krajca, Benjamin Greengold, Edward Merritt
International Journal of Exercise Science: Conference Proceedings
Muscle cramps are involuntary, often painful, skeletal muscle contractions that can occur for multiple reasons including physical exertion, injury, dehydration, nutritional deficiencies, or other neuromuscular conditions. Understanding muscle cramping etiology and treatments is difficult due to their often unpredictable timing and conditions that need to be met for many individuals to experience them. Previous studies have induced muscle cramping through electrical stimulation, long duration exercise, dehydration, and other methods, but these techniques are either non-physiological or complex and time attentive. PURPOSE: Therefore, we aimed to develop a new method to produce a muscle cramp in the biceps brachii in a …

Carbohydrate Effects On Cycling Time To Exhaustion Following Exercise-Induced Glycogen Depletion: Preliminary Data, Ross Moody, Nicole Cipriano, Macilynn E. Coles, Jason Stephens, Sarah Deemer
International Journal of Exercise Science: Conference Proceedings
PURPOSE: In recent years, there has been a rise in the popularity of zero sugar sports drinks which contain fewer calories (from reduced carbohydrate (CHO) content), while maintaining identical electrolyte content. However, substantial evidence demonstrates that CHO consumption before or during exercise enhances performance and supports recovery. Because zero-sugar sports drinks contain only a fraction of the carbohydrate found in traditional full-sugar formulations, they may be less effective for supporting recovery and subsequent performance following muscle-fatiguing exercise. This study investigates whether consuming a full sugar (CHO+), a zero-sugar (CHO-), or water drink following lower-body muscle fatiguing exercise improves cycling …

An elevated homeostatic model assessment of insulin resistance index (HOMA-IR) ≥ 2.5 is commonly used to classify insulin resistance (IR). IR is a well-established precursor to the development of diabetes and other metabolic diseases. Exercise is a well-established intervention for the improvement of metabolic health but the comparison of the effect of exercise among IR and insulin sensitive (IS) non-diabetic adults with the use continuous glucose monitoring has not been adequately studied. PURPOSE: To determine if non-diabetic individuals with insulin resistance have attenuated improvement in exercise-induced improvement in metabolic health and CGM metrics of glycemic control in comparison to …

Obesity and insulin resistance are associated with impaired glycemic control and altered energy metabolism, increasing the risk for cardiometabolic disease. Resistance training (RT) improves body composition by increasing lean mass, which is closely linked to improvements in glycemic control. Neuromuscular electrical stimulation (NMES) enhances glucose uptake and energy expenditure, independent of changes in body composition. The metabolic effects of combining NMES with RT, however, remain understudied. PURPOSE: To determine if combining NMES with resistance training (RT+NMES) results in greater improvement in glycemic control, energy metabolism, and body composition compared to resistance training alone (RT) in untrained overweight and obese …

Abdominal obesity and low muscle mass increase cardiometabolic disease (CMD) risk. Firefighters and law enforcement officers may have high lean body mass (LBM), but occupational stressors raise their risk of abdominal obesity and CMD. Body roundness index (BRI) measures abdominal fat, but it's unclear whether high LBM can counteract the metabolic damage caused by abdominal adiposity in these personnel. PURPOSE: To evaluate (1) the associations of BRI and LBM with cardiometabolic and physical outcomes and (2) LBM's moderating effect (BRI × LBM interaction) on how abdominal obesity relates to health risks. METHODS: A cross-sectional study involving 158 first responders analyzed …

Chronic kidney disease (CKD) will likely progress to renal failure and death without medical or lifestyle intervention. Early detection and treatment of CKD before the development of severe stages (G3b–G5) may provide an opportunity to slow disease progression; however, reliable early detection strategies remain limited. CKD is a systemic condition, and vascular measures have been proposed as potential indicators of renal health. Therefore, this study examined associations between renal function and carotid artery structural characteristics in adults with moderate stages of CKD. PURPOSE: The purpose of this study was to examine the associations between renal filtration markers and carotid …
