KINESIOLOGY 314 LAB EXAM #1 REVIEW 1. Bring a calculator, pencil and eraser. 2. You will be given a “ Formula and Conversions ” sheet similar to the one provided on the last page of this handout. 3. Include the correct units in your answer; points will be taken off for incorrect units. 4. Go through calculations carefully to avoid errors. Be safe, show your work . 5. Read the questions carefully. Make sure you are answering the question (i.e. kcal vs. kcal/min; absolute vs. relative O 2 consumption; work vs. power; estimates vs. calculations from measured variables). Labs #3 and #4: Electrocardiography and Circulation Electrocardiography - Understand the basic electrical activity of the heart. How does the Action Potential spread through the heart and how does this activity achieve synchronized contraction of the atria and ventricles? -What exactly is an ECG?
