VO2 Max Tests Conclusion
Submaximal VO2 tests are extremely useful for determining estimated VO2 maxes for a subject for a variety of reasons. VO2 max measures the maximum amount of oxygen that can be used by a person undergoing intense physical exertion. VO2 max is considered the best test of cardiovascular fitness and aerobic endurance. If a person can utilize more oxygen, then they are able to use that oxygen as a final electron acceptor to make ATP through aerobic metabolism. When an individual’s metabolic requirements, outweigh the amount of oxygen they are capable of delivering, their bodies switch to relying on anaerobic metabolism and will quickly be unable to continue exercising at that given intensity. VO2 max testing can be used in a variety of settings. Fitness centers, potential employers such as firefighters or policeman, or endurance athletes would all be people that would potentially be interested in having a trained individual administer a submaximal VO2 test.
For this class, we performed four submaximal VO2 tests. The Rockport walk test required students to walk for 1 mile (10 laps + 40 yds). A formula was used to calculate VO2 max using time (that is took to walk the mile), age of participant, and heart rate level after the mile walk was completed. For the treadmill test, Bruce protocol was used. ACSM metabolic calculations were used to calculate oxygen consumption, and a multistage model was used to calculate VO2 max. In the forestry step test, subjects walked for 5 minutes at a cadence of 22.5 steps/min. The step heigh for women was 13.25 inches, and 15.75 inches for me. Heart rate was placed into a chart which used a linear relationship to estimate max VO2. The YMCA bike required participants to bike at a variety of resistances that were based on the heart rate after the first stage of the test. The bike test used a liner relationship between HR and exercise intensity to help calculate estimated VO2 max. Oxygen
