Published Research
Impact and Muscle Activation Differences Between Incline Walking and Jogging
At matched isocaloric intensity, level-grade jogging produced significantly higher foot and sacrum accelerations and greater peak and integrated muscle activation—particularly in the tibialis anterior and vastus lateralis—compared to 20% grade incline walking, highlighting incline walking as a lower-impact alternative with comparable metabolic demand.
Physiological and Perceptual Responses to Isocaloric Incline Walking and Jogging
When performed at matched energy cost, 20% grade incline walking and level-grade jogging elicited similar oxygen uptake, heart rate, and substrate oxidation; however, jogging was associated with higher enjoyment and preference scores, indicating meaningful perceptual differences despite equivalent physiological demand.
Treadmill Design and Incline Shape Biomechanical Loading During Locomotion
This study demonstrated that treadmill deck design and incline slope significantly influence impact accelerations, muscle activation patterns, heart rate, and perceived exertion during walking and jogging, indicating that mechanical treadmill characteristics meaningfully affect biomechanical and physiological responses.

Other Projects
Alongside my cycling analysis platform, I’m developing applied projects centered on performance data, visualization, and biomechanics.
Data Visualization & Performance Animations
Developing custom visualizations and animations to communicate complex cycling and physiology data more clearly, including time-series overlays, performance trends, and explanatory graphics for athletes and coaches.
Cadence, Crank Length & Performance Mechanics
An applied biomechanics project examining how cadence and crank length interact with power production, comfort, and performance across different riding conditions.
Applied Cycling Data Experiments
Ongoing exploratory projects using real-world ride data to test analysis methods, compare metrics, and refine how cycling performance is quantified and interpreted.
Educational Tools & Concept Development
Side projects focused on translating performance science concepts into clear frameworks, visuals, and tools for learning and application.
