MIRA Trainee Talks: Sydney Valentino

Sydney Valentino, a MSc student in the Department of Kinesiology at McMaster and recipient of the first Labarge Mobility Scholarship (supervisor Dr. Maureen MacDonald), delivered a talk on her work entitled:
Left ventricular function and stair climbing-based high-intensity interval training in a cardiac rehabilitation population: a proposal
The most powerful part of the heart, the left ventricle, twists with each heart beat to send blood out to the rest of the body – just like wringing out a cloth, this is called left ventricular twist
After a heart attack, there is a decreased ability of the heart to pump blood out which can be measured by left ventricular twist using ultrasound
To combat this, cardiac rehabilitation exercise can reverse negative changes in heart structure by 30% as well as decreasing the chance of reoccurrence and mortality
As an alternative to regular cardiac rehab exercise, we are using stair climbing as a modality for high intensity interval training, which is a time-efficient exercise requiring just a 12-step staircase
If stair climbing and left ventricular twist are as effective as the current exercise and measures used, we see them as additional tools to use in adults going through a cardiac rehabilitation program.
