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 …

The Effects Of Physical Activity On Bone Health In Women As They Age, Shannon A. Matthews, Deborah Rhea, Phil Esposito, Ryan Porter

International Journal of Exercise Science: Conference Proceedings

Osteoporosis affects one in three women over 50, often resulting in fractures that impair mobility and quality of life. Although bone mass and density decline with age, achieving higher peak values before menopause may reduce this risk. Physical activity (PA) is a modifiable factor in skeletal integrity, yet its impact across life stages remains underexplored. Since 80–90% of peak bone mass is accrued by age 16, PA during adolescence and early adulthood is critical. Few studies have examined how specific PA patterns during these periods relate to adult bone health in pre‑menopausal women. PURPOSE: To investigate the relationship between early‑life …

Fatigue-Matched Three Different Squats Elicit Blood Lactate Responses In Young Adults, Jiwon Song, Kase Pennartz, Wonjae Lee, Sarah Deemer, Jakob Vingren, David Church, Joshua L. Keller

International Journal of Exercise Science: Conference Proceedings

Resistance exercise (RE) with blood flow restriction (BFR) promotes muscle hypertrophy, using low external loads and may also improve cognitive function and neuroplasticity, possibly by increasing brain-derived neurotrophic factor (BDNF). Lactate accumulation during exercise has been proposed as a potential mediator of exercise-induced increases in BDNF. However, it is unclear whether different RE loading strategies or BFR under fatigue-matched conditions produce distinct lactate responses that could differentially influence downstream neurotrophic mechanisms. PURPOSE: This study examined blood lactate responses for high-load (HL), low-load (LL), and LL-BFR RE in recreationally active young adults. METHODS: Sixteen healthy, recreationally active young adults …
