Description
The aim of this study was to examine the effect of an individualized overground walking interval training on gait performance [i.e., speed and energy cost (Cw)] in healthy elderly individuals. Twenty-two older adults were assigned to either a training group (TG; n=12, 73.4±3.9yr) or a non-training control group (CG; n=10, 70.9±9.6yr). TG participated in a 7-week individualized walking interval training at intensities progressing from 50 to 100% of ventilatory threshold (ṪVE). Aerobic fitness [maximal oxygen uptake (V̇O2max) and ṪVE], preferred walking speed (PWS), gross and net Cw (GCw and NCw, respectively) and relative effort (%V̇O2max) at PWS measured before training (PWS1) were assessed prior and following the intervention. All outcomes were measured on a treadmill. Significant improvements in GCw (-8%; P=0.007), NCw (-12%; P=0.003), relative effort (%V̇O2max: -12%; P<0.001) and PWS (+12%; P<0.001) were observed in TG but not in CG (P>0.71). V̇O2max and ṪVE remained unchanged in both groups (P>0.57). Changes in GCw at PWS1 (difference between GCw at PWS1 measured pre and post intervention) were inversely correlated with changes in PWS (difference between pre and post PWS; r=-0.67; P=0.02). The decreased Cw at PWS1, with no concomitant improvement in aerobic fitness, represents the main contributing factor for the reduction of the relative effort at this speed. This also allows elderly people to increase their PWS post training. Therefore, the present walking training may be an effective way to improve walking performance and delay mobility impairment in older adults. © 2010 Elsevier Inc.
