Lower body muscle tensing is an effective countermeasure to initial orthostatic hypotension induced cerebral hypo‐perfusion upon standing from a squatted position

PURPOSE to examine the effects of 5 s of lower body muscle tensing (LBMT) after rising from squat on middle cerebral artery blood velocity (MCABV) following a squat‐to‐stand protocol. METHODS Healthy subject (n =8; 24.4 ±1.9 yrs) performed a squat‐to‐stand protocol. Upon standing participants performed either no manoeuvre (Control) or LBMT which was held for 5 s. MCABV (cm/s; surrogate for cerebral perfusion) was measured with transcranial …
