Assessing an athlete’s VO2 max or maximal oxygen consumption, which refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise, is generally considered the best indicator of cardiovascular fitness and aerobic endurance. The more oxygen a person can use during high level exercise, the more energy a person can produce. You will be working at your maximum effort on our Woodway Treadmill at incremental changes of speed and incline and reach your peak performance both safely and effectively.
