My Research Project
My research project was focused on measuring the vascular function and rate of blood flow in arteries of the upper and lower body extremities using flow- mediated dilation (FMD) and plethysmography. We investigated the differences in vascular function on endurance sports that are upper-body predominant, lower- body predominant and mixed combination. FMD is an advanced test that uses ultrasound to measure dilation changes in the diameter of arteries, such as those in the forearm. This is a method to assess the endothelial vascular function in humans. Plethysmography measures changes in volume of blood in different extremities like the upper- or lower-body extremities. These changes are measured with blood pressure cuffs attached to a machine known as the plethysmograph. This test can dictate the amount of blood flowing through the limb and time where peak blood flow happens. It is highly effective when it is used to find changes caused by blood flow. An endurance sport is any sport that has prolonged periods of physical stress. Swimming, for example, combines both cardio and light strength exercises mostly in the upper body, which trains the body to use oxygen more efficiently. Cycling combines both cardio and light strength exercises mostly in the lower body, increasing leg strength and endurance. American football involves a lot of resistance training in both upper and lower extremities. Comparing vascular function and structure in these three sports can help to determine specific changes with training modalities.
Realities of Research
This is my first time working in a lab and my first real research project, so it was pretty scary at first. However, as time passed, I started learning something new every day, including new techniques and skills. I slowly began to understand more about my project and its importance. It has been very exciting to be able to work on this project and being able to see the results.
Life as a Scientist
Working in a lab and being able to work with individuals who share the same passion has truly being an extraordinary experience. One of the greatest things that I personally have witnessed is seeing how all lab members collaborate with one another and help each other out. It has truly been an unforgettable experience to get to know everyone and share endless memories with one another. I love being part of a lab!
