Effects Of Aging On Time-Continuous Lower Extremity Multi-Muscle Coactivation Patterns During Gait, Reece K. Champion, Kiefer A. Hoang, Mohsen Alighanbari

International Journal of Exercise Science: Conference Proceedings

Age related neuromuscular changes include motor unit atrophy and neuromuscular junction destabilization. These changes decrease muscle force output and modulation, and increase motor output variability, leading to joint instability. One compensatory mechanism used to combat joint instability and enhance postural control in older adults is increasing muscle coactivation during tasks like gait. However, the time-continuous nature of multi-muscle coactivation patterns have not been explored to identify during what percentage of the gait cycle alterations emerge. PURPOSE: To identify the effects of aging on continuous multi-muscle coactivation patterns in the knee and ankle joints during gait using statistical parametric mapping …

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 …

Analyzing The Effect Of Aging On Information Flow Among Knee Muscles During Gait Using Symbolic Transfer Entropy, Kiefer A. Hoang, Reece K. Champion, Mohsen Alighanbari

International Journal of Exercise Science: Conference Proceedings

Coactivation is the concomitant contraction of synergistic and antagonistic muscle pairs. Studies using linear coactivation assessments have shown greater coactivation in older than younger adults during gait. Coactivation is a nonlinear phenomenon that may be better examined with nonlinear methods, such as symbolic transfer entropy (STE), which provides the magnitude of information flow and its directionality index (DI). Through analyzing system uncertainty, information flow may provide insight into the communication between coactivating muscles. PURPOSE: To assess the effects of aging on information flow between knee muscles during gait using STE. METHODS: The publicly available dataset used comprises 40 …

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 …

Discordant Visceral Adiposity Phenotypes Reveal Hidden Cardiometabolic Risks, Mia I. Perez, Marcela Guadiana, Grecia V. Morales, Marianna Gamboa, Jose M. Moris

International Journal of Exercise Science: Conference Proceedings

Body Mass Index (BMI) is widely used to screen for cardiometabolic risk but fails to account for Visceral Adipose Tissue (VAT), the metabolically active fat depot linked to cardiovascular disease.
