VO2 max is a valid indication of how efficient your body is able to utilize oxygen to perform work.  Therefore knowing your VO2 max is ideal to give an indication of cardiovascular fitness levels and as a baseline to monitor the progress of a fitness improvement program.  For this assessment we use the revolutionary Polar F92Ti heart monitor watch.  The watch uses the Polar Fitness Test to determine a value known as your “Ownindex” which is a value corresponding to your VO2 max.  Basically, the test involves the watch receiver wirelessly sensing the variability of the heart at rest in either the lying or seated position. From this and other data such as resting heart rate, gender, age, height, body weight and self-assessment of the level of long-term physical activity (last 6 months) the monitor is able to determine a VO2 value having a high reliability comparable to performing a submaximal treadmill VO2 max test.  If performed regularly, the test can provide objective evidence of fitness improvement, which in turn, helps stay motivated and to comply with the personal training program.
