Treatment and study plan

Physical activity

Behavioral

workshops and mobile apps: break sedentary behavior by activity breaks

Primary outcomes

  1. Intervention feasibility

    Time frame: T2: post-intervention (week 12)

    will be assessed using a scale "Feasibility, appropriateness, and acceptability of the intervention"

Secondary outcomes

  1. Sedentary behavior

    Time frame: T1: baseline (before the study begins)

    will be assessed using an accelerometer

  2. Sedentary behavior

    Time frame: T2: post-intervention (week 12)

    will be assessed using an accelerometer

  3. Sarcopenia score ranged from 0 to 20

    Time frame: T1: baseline (before the study begins)

    will be assessed using the Strength, Assistance with walking, Rise from a chair, Climb stairs and (Calf) Falls (SARC-Calf)

  4. Sarcopenia score ranged from 0 to 20

    Time frame: T2: post-intervention (week 12)

    will be assessed using the Strength, Assistance with walking, Rise from a chair, Climb stairs and (Calf) Falls (SARC-Calf)

  5. Blood glucose

    Time frame: T1: baseline (before the study begins)

    will be assessed using a portable blood monitoring device

  6. Blood glucose

    Time frame: T2: post-intervention (week 12)

    will be assessed using a portable blood monitoring device

  7. Blood pressure

    Time frame: T1: baseline (before the study begins)

    will be assessed using a portable blood monitoring device

  8. Blood pressure

    Time frame: T2: post-intervention (week 12)

    will be assessed using a portable blood monitoring device

  9. Muscle strength (handgrip strength)

    Time frame: T1: baseline (before the study begins)

    will be assessed using a hand-held dynamometer

  10. Muscle strength (handgrip strength)

    Time frame: T2: post-intervention (week 12)

    will be assessed using a hand-held dynamometer

  11. Physical performance

    Time frame: T1: baseline (before the study begins)

    will be assessed using Time-Up-to-Go (TUG)

  12. Physical performance

    Time frame: T2: post-intervention (week 12)

    will be assessed using Time-Up-to-Go (TUG)

  13. physical function

    Time frame: T1: baseline (before the study begins)

    will be assessed using Short physical performance battery (SPPB) ranging 0 to 12

  14. physical function

    Time frame: T2: post-intervention (week 12)

    will be assessed using Short physical performance battery (SPPB) ranging 0 to 12
