    Summary
    Impaired balance and gait performance increase fall-risk in seniors. Acute effects of different exercise bouts on gait and balance were not yet addressed. Therefore, 19 healthy seniors (10 women, 9 men, age: 64.6±3.2years) were examined on 3days. After exhaustive treadmill testing, participants randomly completed a 2-km treadmill walking test (76±8% VO2max) and a resting control condition. Standing balance performance (SBALP) was assessed by single limb-eyes opened (SLEO) and double limb-eyes closed (DLEC) stance. Gait parameters were collected at comfortable walking velocity. A condition×time interaction of center of pressure path length (COPpath) was observed for both balance tasks (p<0.001). Small (Cohen's d=0.42, p=0.05) and large (d=1.04, p<0.001) COPpath increases were found after 2-km and maximal exercise during DLEC. Regarding SLEO, slightly increased COPpath occurred after 2-km walking (d=0.29, p=0.65) and large increases after exhaustive exercise (d=1.24, p<0.001). No significant differences were found for gait parameters. Alterations of SBALP after exhaustive exercise might lead to higher fall-risk in seniors. Balance changes upon 2-km testing might be of minor relevance. Gait is not affected during single task walking at given velocities
