Fractional Synthetic Rate And Markers Of Protein Turnover Are Altered In The Diaphragms Of Cachectic Mice, Conner A. Benson, Nicholas P. Greene, Jacob L. Brown, Megan E. Rosa-Caldwell, Tyrone A. Washington, Richard A. Perry, Michael P. Wiggs

International Journal of Exercise Science: Conference Proceedings

Cancer cachexia, a wasting syndrome characterized by rapid skeletal muscle wasting and fat loss, directly accounts for up to 20-40% of cancer-related deaths. All muscles, including respiratory muscles, are susceptible to atrophy because cancer cachexia is a systemic disease. Atrophy of the primary breathing muscle, the diaphragm, can lead to respiratory distress, which is commonly associated with a cachectic phenotype. Indeed, the diaphragm is more susceptible to atrophy in certain conditions, but little is known about the effects of cancer-cachexia on protein turnover in the diaphragm. Therefore, investigations into the alterations in protein turnover could provide insight to the molecular …

International Journal of Exercise Science: Conference Proceedings

A family history of type 2 diabetes (FH+) is considered a risk factor for insulin resistance and poor cardiorespiratory fitness. However, it is not known if a FH+ impedes exercise-induced improvements in maximal aerobic capacity (VO₂max). Purpose: The purpose of this study was to determine if normoglycemic, sedentary, Hispanic men with FH+ have a lower VO₂max compared to those without a family history of type 2 diabetes (FH-) and if the improvement in VO₂max after 8-weeks of combined exercise training is comparable between FH- and FH+. Methods: 20 participants underwent 8 weeks of combined …

The Dose Effect Of Whey Protein On Insulin Responses In Pre-Diabetics And Type 2 Diabetics, Todd Castleberry Mr., Christopher Irvine 5098522, Michael Oldham, Matthew F. Brisebois, Sarah E. Deemer, Ryan Gordon, Aubrien Henderson, Vic Ben-Ezra

International Journal of Exercise Science: Conference Proceedings

People with pre-diabetes and type 2 diabetes have shown an increase in insulin secretion after ingesting 55 g of whey protein coupled with a glycemic challenge. However, the effect of lower amounts of whey protein on insulin responses remains unclear. Our hypothesis was that both 20 g and 30 g of whey consumption prior to an oral glucose tolerance test (OGTT) would produce an increase in insulin secretion, with 30 g producing the greatest increase compared to a control. PURPOSE: The purpose of this study was to examine the effect of two different doses of whey protein ingested 30 min …

GLP-1 and GIP have been shown to increase following a 50 g dose of whey protein prior to a high glycemic load in type 2 diabetics. However, this increase is reduced in diabetics compared to healthy individuals. Pancreatic polypeptide (PP) and peptide tyrosine tyrosine (PYY) also increase, while ghrelin decreases after the consumption of whey protein; however, it is not known if a similar hormone response occurs with a lower dose of whey protein prior to a glycemic load or if there is a dose effect. Our hypothesis was that 20 g and 30 g of whey protein would increase …

A Family History Of Type 2 Diabetes May Impair Glucose Area Under The Curve In Young, Healthy Hispanics, Cesar Meza, Manuel Amador, Mario Garcia, Christopher Figueroa, Andrew Mcainch, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Obesity and type 2 diabetes are associated with impaired glucose homeostasis and blood lipid profiles. Further, a family history of diabetes (FH) increases the risk for development of insulin resistance. However, it is unclear whether a FH impairs glucose tolerance, blood glucose and lipid profiles in young, healthy, normoglycemic adults. PURPOSE: To investigate whether a FH impairs glucose tolerance and blood lipid profile in healthy, sedentary Hispanic males. METHODS: 22 sedentary, normoglycemic, Mexican American males (mean±SEM: age:23±0.56 yrs; BMI: 26.9±0.98 kg/m²) with/without FH participated in the study.
