Card preview (13)
repeated bouts of cardiovascular exercise performed at high intensity for 30sec- several min followed by 30 sec-5 min of recovery
HIIT
Karvonen forumal
220-age=MHR MHR-RHR= HRR HRR (.70) and HHR (.80)= training range %
what is the karvonen beta blocker correction
max HR=164- (0.7 x age)
what training zone do we want on a 20 point RPE scale
13-16 somewhat hard to hard
what is the American Physical Activity Guideline?
at least 150 min of mod-intensity aerobic activity a week at least 2 days a week of muscle strengthening
what are some benefits to HIIT
improved Vo2 max improve insulin sensitivity improved endothelial function decrease LDL and increase HDL decrease BP
how did individuals with COPD benefit from a 12 week HIIT protocol
improved peak VO2 improved quad strength improved daily step count decreased time in sedentary activities improved HR-QoL
how did individuals with CVa benefit from HIIT as opposed to MICT
improved ventilatory threshold, O2 utilization, gait speed improved stride length, gait speed improved functional ambulation category
Which intervention is more helpful to reducing fall risk? HIIT or strengthening, balance and coordination
strengthening, balance and coordination
what is typically the preferred mode to administer ambulatory individuals with stroke assuming no precautions/contraindications
treadmill
patient with history of CVA and left hemiparesis (8 months ago) gait speed is 0.4 m/sec with a single point cane and supervision what is the suggested % of body weight
0%
in the CPG for improved locomotor function of stroke, incomplete spinal cord and brain injury what is the strong level of evidence in ambulatory pop >6 months post acute CNS injury
• walking training at mod to high intensity • virtual reality- based training to improve walking speed and distance • PT should NOT perform body weight supported treadmill training
among individuals with CAD, MI and heart failure there have been __ nonfatal cardiac arrests in more than 46,000 hours of HIIT
