Objective: To investigate the effects of age and feedback on submaximal isometric force control abilities in the knee extensors.
Design: Analysis of a force control task in a quasi-experimental design.
Background: The ability to control submaximal strength is important to accomplish activities of daily living.

Article Synopsis
- The study examines how age, reaction conditions, and step direction influence the speed of voluntary stepping in adults.
- Results showed that older participants experienced slower response, liftoff, and landing times compared to younger adults.
- Additionally, more complex decision-making (choice reaction) and step direction negatively impacted stepping performance, indicating that these factors should be considered in balance assessments.
