Osteoporosis is a silent disease that is typically not diagnosed until after a fracture has occurred. Identifying biomarkers routinely collected by physicians can serve as a simple and effective screening approach to detect osteoporosis before debilitating fractures occur. The ratio of total estradiol to total testosterone (ET x10)/TT has been proposed as a biomarker associated with bone mineral density (BMD). To further improve predictive power, we propose a ratio of estradiol to free testosterone (ET/TF), rather than total, to account for the difference in hormone bioavailability. PURPOSE: The present analysis compares the association …

Speg Activation To Regulate Sarcoplasmic Reticulum In Muscle Disease, Lauren Nguyen, Sara Kondamadugula, Ting Chang, Susan Hamilton
International Journal of Exercise Science: Conference Proceedings
Sarcoplasmic reticulum (SR) Ca2+ leak contributes to many muscle diseases, including Duchenne Muscle Dystrophy (DMD) and Malignant Hyperthermia (MH) with enhanced sensitivity to heat stroke. Recently, we demonstrated that the striated muscle preferentially expressed protein kinase, SPEG, decreases SR Ca2+ leak by phosphorylating Ser2902 on the Ca2+ release channel (also known as the ryanodine receptor 1, RYR1). While SPEG is activated in response to increased leak, the mechanisms of this activation are unknown. In addition, this compensatory mechanism is overwhelmed in the disease states associated with excessive Ca2+ leak. Increasing SPEG activation could potentially be beneficial …

Calculation Of A Conversion Factor To Estimate Anaerobic Energy In Trained Men And Women Runners, Austin B. Shaw, Ethan J. Hein, Brady C. Mclain, Jacob L. Mcnary, Sarah E. Deemer, Lydia K. Caldwell, David W. Hill
International Journal of Exercise Science: Conference Proceedings
Accurate quantification of anaerobic energy contribution is crucial for sport performance and bioenergetics research. A recently popularized method estimates anaerobic contribution and capacity from a single exercise test by multiplying post-exercise blood lactate by an oxygen equivalent (O2–Eq–Lac; historically 2.7–3.3 mL·kg–1·mM–1). Foundational studies have empirically derived this conversion factor across modalities: two have reported 3.0–3.3 mL·kg–1·mM–1 for running, two have obtained 2.7 mL·kg–1·mM–1 for swimming, and one has determined 3.0 mL·kg–1·mM–1 for cycling. These studies are based on physiological assumptions (e.g., the caloric equivalent …
