Gait speed (GS) has been recognized as an integral component of functional independence. Further, step length (SL), cadence (CAD) and the percentage of the gait cycle in spent in stance (%ST) have been associated with risk of falls and mobility disability among older adults. Purpose: This study examined temporal spatial gait variables in young and low and high functionally fit older adults. Methods: Twenty older and 12 younger adults (CON; M±SD = age: 22.3±1.8, height 1.7±0.1 m, mass 66.1±11.8 kg) completed two 20 m habitual walking trials and the fastest time was recorded. Selected gait variables were averaged from the foot strikes across a gait mat. Functional fitness (FF) was assessed using a stair climb test and relative power was used to create the low (LFF; n = 8; M±SD = age: 73.9±6.9, height 1.6±0.2 m, mass 76.6±15.5 kg) and high (HFF; n= 12; M±SD = age: 70.1±4.2, height 1.75±0.1 m, mass 72.1±14.9 kg) functionally fit older adult groups. A one-way ANOVA was used to assess differences between the groups on the dependent variables of gait. Results: The results yielded a statistically significant difference (p < .05) between the groups for GS, SL, and percentage of swing (%SW) and %ST. The LFF group walked significantly slower than both the CON and HFF group but, there was not a difference in speed between the CON and HFF. The LFF group also spent more time in stance, less time in swing, and had a shorter SL than the CON; however, there was not a difference between the LFF and HFF groups on these variables. The HFF group was not different from the CON on GS, SL, %SW or %ST. Conclusions: The findings of this study suggest that as one ages if they maintain a higher level of FF then they do not express the same age-related changes in gait as those with a lower level.
