What Is VO2 Max Testing and Why Is It Important?

VO₂ Max: One of the Most Important Numbers for Healthy Aging

Most people know their blood pressure, cholesterol, or weight. Far fewer know their VO₂ max. Yet this single number can provide remarkable insight into your current fitness, your future health, and even your ability to remain active and independent as you age.


What Is VO₂ Max?


VO₂ max (pronounced "V-O-two max") is the maximum amount of oxygen your body can use during intense exercise. It reflects how well your heart, lungs, blood vessels, and muscles work together to deliver and use oxygen.


Simply put, it is one of the best measures of your cardiovascular fitness.


The higher your VO₂ max, the more efficiently your body can perform physical activity. While endurance athletes often have exceptionally high VO₂ max values, improving this number benefits everyone—not just runners and cyclists.


Why Does VO₂ Max Matter?


Research has consistently shown that VO₂ max is one of the strongest predictors of long-term health and longevity.

People with higher levels of cardiorespiratory fitness generally have a lower risk of heart disease, stroke, type 2 diabetes, and premature death. In fact, low cardiorespiratory fitness has been shown to be as significant a health risk as many traditional risk factors, including smoking, high blood pressure, and diabetes.


Many experts in longevity and preventive medicine consider VO₂ max one of the most important measures of long-term health, because it reflects not only how long we may live, but how well we are likely to function as we age.


VO₂ Max and Healthy Aging


As we age, VO₂ max naturally declines. If that decline becomes significant, everyday activities can become increasingly difficult.


Walking up stairs, carrying groceries, traveling, hiking with family, or simply keeping up with grandchildren all require a certain level of aerobic fitness.


People who maintain a higher VO₂ max throughout life are more likely to remain active, independent, and physically capable well into older age. Rather than simply adding years to life, improving VO₂ max helps add life to those years.


How Is VO₂ Max Measured?


The most accurate way to measure VO₂ max is through a graded exercise test while wearing a specialized mask that measures the oxygen you inhale and the carbon dioxide you exhale.


During the test, you walk on a treadmill or pedal a stationary bicycle while the intensity gradually increases. Your heart rate, breathing, and oxygen consumption are measured throughout the test.


The procedure is safe, non-invasive, and typically takes less than 20 minutes.


Can You Improve Your VO₂ Max?


Absolutely!


Unlike some health markers that are largely determined by genetics, VO₂ max can often be improved with regular exercise.


The most effective strategies include:

  • Regular aerobic exercise such as brisk walking, cycling, swimming, or jogging
  • Interval training that includes short periods of higher-intensity effort
  • Consistent strength training to maintain muscle mass and overall fitness
  • Gradually increasing the duration and intensity of exercise over time


Even modest improvements in VO₂ max can translate into meaningful improvements in health, energy, and physical function.


Why We Measure VO₂ Max


At Rivanna Concierge Physicians, we believe that preventing disease is only part of the picture. Our goal is to help patients maintain strength, mobility, and independence throughout life.


VO₂ max testing gives us an objective way to measure one of the most important indicators of healthspan—the years you remain healthy, active, and capable. It helps establish a baseline, identify opportunities for improvement, and track progress over time.


Whether your goal is to lower your risk of disease, improve athletic performance, or simply continue doing the activities you love for decades to come, understanding your VO₂ max is an important step.

 

Looking Beyond the Numbers


VO₂ max is not about training for a marathon or competing with others. It's about understanding how well your body functions today and taking steps to improve how you'll function tomorrow.


Healthy aging isn't just about living longer. It's about living better—maintaining the strength, endurance, and independence to enjoy the people and activities that matter most. VO₂ max testing provides a valuable window into your overall fitness today and helps guide a plan to improve your healthspan for years to come.

When most people think about menopause, the first symptoms that come to mind are probably hot flashes and night sweats. These are among the most common symptoms of the menopause transition, affecting up to 80% of women at some point. But menopause is much more than hot flashes. The hormonal changes of perimenopause and menopause can affect virtually every system in the body. Some symptoms are subtle, develop gradually, or are easily attributed to stress, aging, or simply having too much on your plate. As a result, many women don’t realize that the changes they are experiencing may be related to the menopause transition. What exactly is happening during menopause? Perimenopause is the transition leading up to menopause. During this time, ovarian hormone levels, particularly estrogen, can fluctuate considerably. Menopause itself is defined retrospectively after 12 consecutive months without a menstrual period. While the experience is different for every woman, the hormonal changes of this transition can affect the brain, sleep, genitourinary system, musculoskeletal system, and cardiovascular and metabolic health. And importantly, you don’t have to have hot flashes to be experiencing menopause-related symptoms. Symptoms beyond hot flashes 1. Sleep changes Sleep problems are extremely common during the menopause transition. Some women have difficulty falling asleep. Others begin waking during the night or find that they wake much earlier than they used to. Night sweats can certainly disrupt sleep, but sleep disturbance can occur even in women who don’t experience obvious hot flashes. Poor sleep can then create a cascade of other problems, including fatigue, irritability, difficulty concentrating, reduced exercise tolerance, and changes in appetite. 2. “Brain fog” and memory changes One of the most frustrating symptoms women describe is a feeling that their brain simply isn’t working the way it used to. You may find yourself: Searching for a familiar word or name Walking into a room and forgetting why you went there Having more difficulty concentrating Becoming more easily distracted Struggling to multitask Feeling mentally “foggy” or less sharp These cognitive complaints are common during the menopause transition. The Menopause Society notes that approximately 40% to 60% of midlife women report cognitive symptoms during this period. For many women, this can be particularly concerning. It is important to distinguish the common, generally mild cognitive changes associated with the menopause transition from the progressive cognitive decline seen with dementia. Persistent or significant cognitive changes should still be evaluated rather than automatically attributed to menopause. 3. Mood changes, irritability, and anxiety Some women notice a change in their emotional baseline during perimenopause. You may feel: More irritable or short-tempered More anxious Less resilient to everyday stress More easily overwhelmed Less motivated or more down than usual Women with a history of depression may be particularly vulnerable during this period, but menopause-related mood symptoms can occur in women without a prior psychiatric history. And sometimes the symptom isn’t simply “depression.” A woman may tell us, “I just don’t feel like myself anymore.” That deserves attention. 4. Joint and muscle aches New or worsening aches and stiffness can also occur around menopause. A woman who has always been active may suddenly notice that her knees, hips, shoulders, or hands are more uncomfortable, or that she needs longer to recover after exercise. Not every new ache is caused by menopause, and conditions like arthritis, injuries, and thyroid disease still need to be considered. But the timing of new musculoskeletal symptoms can provide an important clue. 5. Changes in sexual health Sexual symptoms are common but are often underreported. Declining estrogen levels can cause changes in the tissues of the vulva and vagina, including: Vaginal dryness or reduced lubrication Burning, irritation, or discomfort Pain with intercourse Decreased sexual satisfaction Some women also experience a decrease in sexual desire. These symptoms fall within what is called genitourinary syndrome of menopause (GSM). Unlike hot flashes, which often improve with time, GSM can become progressively more bothersome without treatment. 6. Urinary changes Changes in estrogen can affect the bladder, urethra, and surrounding tissues. Women may notice: Increased urinary frequency Urgency Leakage Burning with urination Recurrent urinary tract infections Waking during the night to urinate Because urinary symptoms have many possible causes, they should not automatically be attributed to menopause. But menopause should be part of the conversation, particularly when symptoms develop during or after the menopause transition. 7. Headaches and migraines For some women, hormonal fluctuations during perimenopause can make headaches or migraines more frequent or more severe. Women who have historically experienced menstrual migraines may notice a change in their pattern as estrogen levels fluctuate. A new or substantially different headache, however, should always be appropriately evaluated rather than assumed to be hormonal. 8. Changes in weight and body composition Many women notice changes in their body composition during midlife, even when their diet and exercise habits haven’t changed dramatically. The issue isn’t simply the number on the scale. Women may notice: Changes in where fat is stored, particularly around the abdomen Loss of muscle mass Greater difficulty maintaining their previous weight Aging itself plays an important role in these changes, as do activity level, nutrition, sleep, genetics, and hormonal changes. Menopause isn’t the sole explanation, but it is an important part of the picture. This is one reason why preserving muscle mass, strength, cardiovascular fitness, and metabolic health becomes increasingly important during midlife. Why recognizing the full picture matters One of the challenges of menopause care is that there is no single “menopause symptom.” A woman may have classic hot flashes and night sweats. Another may primarily notice insomnia, anxiety, brain fog, and joint stiffness. Another may have significant vaginal and urinary symptoms but no vasomotor symptoms at all. And sometimes several seemingly unrelated symptoms appear around the same time. That doesn’t mean every symptom occurring in midlife is caused by menopause. Thyroid disease, anemia, sleep apnea, depression, medication effects, nutritional deficiencies, autoimmune disease, and other medical conditions can produce symptoms that overlap with menopause. Good menopause care recognizes patterns, considers the alternatives, and treats the symptoms that are actually affecting a woman’s quality of life, rather than attributing everything to hormones. You don’t have to simply “live with it” Menopause is a normal biological transition, not a disease. But “normal” does not mean women should simply accept symptoms that interfere with their sleep, relationships, work, exercise, or enjoyment of life. There are effective approaches to many menopausal symptoms, including lifestyle strategies, nonhormonal therapies, and hormone therapy when appropriate. The right approach depends on a woman’s symptoms, medical history, risk factors, preferences, and goals. At Rivanna Concierge Physicians, we believe menopause care should be individualized rather than one-size-fits-all. We take the time to understand the full picture, not just whether you are having hot flashes. Because feeling well in midlife isn’t about simply getting through menopause. It’s about helping you feel like yourself and remain healthy, active, and engaged for the decades ahead. If any of this sounds familiar, we’d welcome a conversation. We engage seriously with the things traditional primary care doesn’t have time for: hormone health, sleep, energy, metabolic changes.
