Fatigue is a critical health parameter in older adults and stroke patients and is associated with negative health outcomes. Current assessment tools predominantly focus on walking related fatigue, neglecting other activities of daily living (ADLs). This study aims to fill this gap by developing a standardized, laboratory-based fatigue protocol that includes a broader range of ADLs, providing a more comprehensive fatigue assessment that's in line with the WHO vision of healthy ageing. The aim of this study is to evaluate a lab-based fatigue protocol and to unravel the relationship between physiological or movement data and perceived fatigue. Participants will take part in three separate measurement moments, during which they will execute a performance task that induces fatigue. In addition, relevant sensors will be used to collect meaningful data.

The participant will be asked to execute a protocol in the movement lab that induces progressive feelings of fatigue. This protocol includes a sequence of relevant functional activities, such as stair walking, slope walking, crouching, walking different path shapes. During this execution the Ratings of Perceived Exertion will be questioned, and simultaneously physiological and movement data will be collected.

Changes in the Ratings of Perceived Exertion throughout the protocol execution
The subjective feelings of fatigue will be evaluated through the Ratings of Perceived Exertion. This will be expressed verbally by the participant throughout the execution of the protocol.
