Abstract
Diedrich and Warren (1995) and Whitall and Getchell (1995) found that intralimb coordination during walking was different than intralimb coordination during running. In contrast, Li et al. (1998) found that intralimb coordination during walking and running were similar. The discrepancy between these findings could have been the result of (1) the use of theoretically unacceptable intralimb collective variables, (2) measurement error during data collection, and/or (3) calculation error during data analysis. Thus, the purpose of this investigation was to simultaneously test three potential intralimb collective variables of locomotion, similar to the ones used previously, in an attempt to understand the nature of the equivocal findings. Forty young adults participated in this study. Each participant performed slow, preferred, and fast speed walking trials and slow, preferred, and fast speed running trials. The results indicated that hip-ankle and knee-ankle relative phase variables demonstrated different patterns for walking and running, while, hip-knee relative phase did not. It was concluded that both hip-ankle and knee-ankle relative phase variables can be considered acceptable intralimb collective variables of locomotion within a Dynamical Systems theory framework (Haken, Kelso, & Bunz, 1985; Kelso, 1984).
