VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense exercise. It serves as a crucial measure of cardiovascular fitness and aerobic endurance. VO2 max testing is considered the gold standard for evaluating cardiovascular health and fitness levels. Higher VO2 max values typically indicate better physical conditioning and cardiovascular health.
The importance of VO2 max lies in its ability to assess the efficiency of oxygen utilization by the body's tissues during physical activity. It reflects the capacity of the cardiovascular and respiratory systems to deliver oxygen to the muscles during exercise. Individuals with higher VO2 max values are better equipped to perform sustained, high-intensity physical activities and experience reduced risk factors associated with cardiovascular diseases, such as heart attacks and strokes. A lower VO2 max is associated with greater risk of cardiovascular disease and all-cause mortality, according to the American Heart Association.
Generally, VO2 max declines by approximately 10% per decade after the age of 30 in healthy sedentary adults. Regular physical activity and exercise can help mitigate the decline in VO2 max associated with aging. Masters athletes who continue training demonstrate slower declines in VO2 max compared to sedentary individuals
How can you measure your VO2 Max at home?
Personal fitness device: Some fitness devices provide VO2 max readings. Many trackers also offer other sophisticated physiological measurements. A few brands have their own calculations for VO2 max, be mindful that accuracy outside of the lab will suffer and likely give a falsely low reading [7].
Online calculator: VO2 max has been around for a while, multiple approaches are available to estimate your VO2 max based on basic personal data. One such calculator was created by the Norwegian Institute of Science and Technology (NTNU), which based its results on data provided by a large population of people. It gives you both a fitness score for your age and an equivalent VO2 max number [7].
How can you improve your numbers?
High-Intensity Interval Training (HIIT): HIIT stands out as a promising method for enhancing VO2 max. Studies suggest that HIIT, characterized by short bursts of intense exercise followed by rest periods, is highly effective in increasing VO2 max [6]. Fartlek training is one of many techniques.
Endurance Training: Endurance training, involving sustained, moderate-intensity exercise over time, is also recognized for its ability to elevate VO2 max levels. Research indicates that consistent endurance training leads to notable improvements in aerobic capacity and VO2 max [5]. Maximum aerobic function training by Dr. Phil Maffetone is an example of an endurance program
Interval Training: Interval training, similar to HIIT but with longer work and rest intervals, has been shown to elicit increases in VO2 max. Studies demonstrate the effectiveness of structured interval training programs in improving cardiovascular fitness and VO2 max [4].
Resistance Training: While less traditional for improving VO2 max, resistance training has shown potential. Studies indicate that resistance training can lead to increases in VO2 max, especially when combined with aerobic exercise [5].
Training Intensity: The intensity of exercise training plays a crucial role in improving VO2 max. Research suggests that training at higher intensities, such as those near or above VO2 max levels, can effectively enhance aerobic capacity [4].
Studies demonstrate Vo2 max can be slowed as we age. It is used to measure our cardiovascular health and overall fitness. Measure it before and after a training program (6-12 weeks). Multiple case studies show that our numbers can be altered with exercise.
