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.

Interested in working with me?
I work at the intersection of endurance sport, science, and storytelling. Through coaching, racing, and research-backed education, I help athletes understand why they train, not just what to do. My audience is primarily everyday endurance athletes, cyclists, and curious humans who care about performance, health, and enjoying the process.
