Outcome Measures

Primary Outcomes (1)

  • Peripheral muscle blood flow, gait speed and handgrip strength

    Check if there is a correlation between peripheral muscle blood flow, gait speed and handgrip strength and if this association is mediated by inspiratory muscle strength.

    Day 1

Interventions

Pimax and Pmax will be performed according to the (ATS) and (ERS). A Manovacuometer (Analog M 120, GlobalMed) with a range between 0-120cmH2O will be used. The elderly should undergo forced inspiration after maximal expiration and forced expiration after maximal inspiration through a mouthpiece with a hole to prevent closure of the glottis to evaluate Pimax and Pmax. The elderly should sustain the inspiration for 1 second. Three measurements will be performed, with a one-minute interval between them, with less difference equal to 10% between them, the higher value will be used.
