Just as your fitness improves over time, it declines if you stop training. Significant reductions in your cardiorespiratory fitness, that is VO2max, occur already within 2 to 4 weeks of detraining.
VO2max is generally regarded as the best indicator of cardiorespiratory fitness. The higher your VO2max, the better your aerobic fitness.
You may have heard that your fitness level is determined by your genetics. This is true. Luckily, that’s not the whole story. Experts say that about half of the variation in physical fitness between individuals is heritable, meaning it comes to you through your parents.
When it comes to your health and fitness, it’s easy to ask the wrong questions. “Am I fit?” is one of these questions that just creates problems. Thinking about your fitness in terms of VO2max is the easiest way to get started.
Results matter. In terms of understanding whether your activity and lifestyle profile translates into real health benefits, VO2max – the defining metric of cardiorespiratory fitness (CRF) – is the perfect resource.
This technology is new to many, but the groundwork for this revolutionary step has been carefully developed and curated by Firstbeat for well over a decade.
