Abstract

​​Walking may seem simple, but it is actually a carefully coordinated process involving balance, rhythm, and efficiency. The way we walk—our gait—changes depending on speed. At slower speeds, people tend to take shorter, more careful steps. At faster speeds, stride length usually increases and step frequency (cadence) rises to keep up. Biomechanics researchers study these patterns to understand how speed influences gait mechanics and stability, since walking is one of the most important forms of human movement. Can you identify what your ideal walking speed is - the best combination of speed and stability?

Studying gait is not just for scientists in the lab. Walking speed, stride length, and stability are commonly measured in clinical settings to monitor health and mobility, especially in older adults or people recovering from injuries. Research has shown that faster walking speeds often improve efficiency but may reduce stability, while slower speeds can increase stability but make walking less energy-efficient. Athletes, physical therapists, and even engineers designing wearable devices all rely on this type of gait analysis to improve performance and safety.

In this project, you will investigate how walking speed affects stride length, cadence, and gait stability. To take analysis one step further, you can use a smartphone accelerometer or videos to track and analyze step timing, stride length, or even body sway. By collecting and comparing data across different speeds, you will learn how speed changes the mechanics of walking and gain insight into the balance between efficiency and stability in human gait.

Career Profile

If you are injured in an accident, suffer a stroke, heart attack, or loss of a limb, or are born with conditions that make it difficult to move your body, then you will often be cared for by a physical therapist. Physical therapists review a patient's medical history, test and measure his or her physical condition (things like range of motion, strength, flexibility, balance, coordination, muscle function), and then develop a treatment plan to meet some physical goals. They coach, motivate, and… Read more

Career Profile

Sports injuries can be painful and debilitating. Athletic trainers help athletes, and other physically active people, avoid such injuries, while also working to improve their strength and conditioning. Should a sports injury occur, athletic trainers help to evaluate the injury, determine the treatment needed, and design a fitness regime to rehabilitate the athlete so he or she is ready to go out and compete again.
