The Effects Of A Single Bout Of Endurance Exercise On Glucose Transporter-4 (Glut-4) Content, Manuel Gomez, Sudip Bajpeyi
International Journal of Exercise Science: Conference Proceedings
Glucose Transporter protein-4 (GLUT-4) is considered the predominant glucose transporter in skeletal muscle. Exercise has been shown to increase glucose uptake and GLUT-4 protein content in skeletal muscle following muscle contraction. PURPOSE: To determine the acute effects of a single bout of moderate intensity endurance exercise on skeletal muscle GLUT-4 content. METHODS: 10 healthy male volunteers (age: 24.4 ± 1.3 years; BMI 23.16 ± 0.60 kg/m²) participated in a single bout of endurance exercise on a cycle ergometer at 65% maximal aerobic capacity (VO2max) for 1.5 – 2.0 hours (650kcal). Muscle biopsies were obtained from the vastus …

Running Economy Strongly Related To Ground Contact Time Imbalances, Aaron D. Piper, Erica G. Knowles, Nicholas A. Guerra, Eric J. Jones, Dustin P. Joubert
International Journal of Exercise Science: Conference Proceedings
Running economy (RE) can be defined as the oxygen consumption or caloric unit cost required to move at a specific velocity. In addition to a runner’s maximal oxygen uptake (VO2max) and lactate threshold (LT), RE is a key endurance performance determinant. Better RE is advantageous as it represents the ability to run at a lower relative percentage of VO2max at a given speed and reduces the rate of energy depletion. Ground contact time (GCT) has been associated with RE, however it has not been established how GCT imbalances between feet impact economy. Purpose: Determine the relationship between cadence, GCT, and …
Inflammation-Associated Rna Signaling Is Reduced Following A Half-Marathon Race When Supplemented With Curcumin And A Pomegranate Extract, Elizabeth A. Tanner, Melody A. Gary, Asheal A. Davis, Brian K. Mcfarlin
Inflammation-Associated Rna Signaling Is Reduced Following A Half-Marathon Race When Supplemented With Curcumin And A Pomegranate Extract, Elizabeth A. Tanner, Melody A. Gary, Asheal A. Davis, Brian K. Mcfarlin
International Journal of Exercise Science: Conference Proceedings
Prolonged endurance exercise performances provide a unique model for investigating the combined effects of oxidative stress and eccentric muscle contraction on differential gene expression with nutritional interventions known to blunt inflammation. Dietary polyphenols (i.e. curcumin, pomegranate, etc.) have been shown to reduce exercise-induced inflammation associated mRNA and protein expression with fewer side effects than NSAIDs. PURPOSE: To investigate the effect of combined curcumin (500-1000 mg/d; Longvida®) and pomegranate extract (500-1000 mg/d; Pomella®) supplement for 30-days on mRNA expression following a half marathon race. METHODS: All protocols were approved by the University IRB committee and participants gave written informed consent. Participants …

International Journal of Exercise Science: Conference Proceedings
Individuals participating in prolonged exercise sessions and associated training experience regular inflammation and muscle soreness. Natural products with known anti-inflammatory and/or oxidative stress blocking effects represent attractive options to traditional NSAID treatments. PURPOSE: To investigate the effect of combined curcumin (500-1000 mg/d; Longvida®), pomegranate extract (500-1000 mg/d; Pomella®), and Methylsulfonylmethane (500-1000 mg/d; OptiMSM®) supplement for 30-days on protein inflammatory biomarkers, inflammation-associated RNA, and oxidative. METHODS: All protocols were approved by the University IRB committee and participants gave written informed consent. Subjects were supplemented for 30-d prior to the half marathon race. Venous blood samples were collected for serum or RNA …
