Training Effects on Running Gait Variability in Older Adults

Gait stability is crucial for functional independence in older adults, as it is closely associated with an increased risk of falls and mobility loss. While physical activities like running offer significant health benefits, they challenge gait stability (Savelberg et al. 2007). To effectively assess stability, one should quantify variability between and within an individuals, as excessive f luctuations in stride parameters can indicate compromised control mechanisms. One approach to measuring variability is through signal entropy, capturing the complexity and adaptability of gait patterns. Higher entropy may indicate a healthier, more adaptable system, whereas lower entropy can reflect rigidity, chaos or loss of control. By analysing gait entropy alongside traditional measures of inter-subject variability like the coefficient of variation (CV), we aim to improve understanding of gait stability differences between a young and older population during running.
