Quick Health Tip - Cardiorespiratory Fitness (“CRF”) Maximal Values and Cautions

Cardiorespiratory Fitness (“CRF”) assessment intends to find an individual’s VO2 max. Predicting maximal values is done through performance measures that are converted into O2 expression. The options include walking, running, biking, step-ups, and swimming. It is important to note that when conducting these tests there are indications on when to stop. For the person who is working out, they include discomfort, pale skin, inability to focus, loss of rhythm for a minimum of 20 seconds, faintness, vomiting, breathing complications, chest pains, and cramps.
