* ≤ 0.05, ** ≤ 0.01, *** ≤ 0.001. Effect size: eta-squared η². STEP95 95th percentile of cadence, MADmedian median of all MAD values, Unintentional weight loss loss of appetite or decreased food intake, Exhaustion too little energy to execute daily tasks, Low muscle strength not able to carry objects of more than 5 kg, Low physical activity being engaged in at least moderate PA on less than once per week, Weakness not being able to take more than one flight of stairs without rest
