Sleep Deprivation Effects on Running Style and Biomechanics

A recent study conducted by researcher Maura Seynaeve and her colleagues at KU Leuven in Belgium investigates how sleep deprivation alters running biomechanics, revealing that lack of sleep reduces alertness and changes physical movement during a treadmill run. The researchers analyzed 11 women and 10 men who performed two treadmill runs one week apart under conditions of total sleep deprivation and normal rest, utilizing waist-mounted accelerometers and motion-capture cameras to track physiological changes. The findings indicate that sleep-deprived runners take 1 to 3 fewer steps per minute at the same speed, experience increased ground contact time, and alter joint loading, which may elevate the risk of injuries such as knee problems. Athletes and fitness enthusiasts should prioritize adequate sleep recovery before high-intensity workouts and training sessions to maintain optimal biomechanical performance and reduce injury risks.
