Significant associations were found between low ventilatory capacity and slow gait speed ( adjusted odds ratio ( aOR ) = @ , @ % confidence interval ( CI ) = @-@ @ ) , between respiratory muscle weakness and moderate to severe mobility impairment ( aOR = @ , @ % CI = @-@ @ ) , and between dyspnea and high sedentary time ( aOR = @ , @ % CI = @-@ @ ) and slow gait speed ( aOR = @ , @ % CI = @-@ @ ) .
