One MET is the calculation of how much energy, measured in calories, you expend while at rest. Metabolic equivalent (MET) is a ratio of the amount of oxygen consumed while at rest compared to the amount of energy expended when you’re exercising. There are two metrics used to provide insight into the health of your cardiorespiratory system: METs and VO2 Max. How To Measure Cardiovascular EnduranceĬardiovascular endurance involves measuring the amount of oxygen your body uses during intense exercise. If you have poor cardiovascular endurance, you won’t get enough oxygen to your muscles and you may feel light-headed or start to experience fatigue. This means your cardiovascular system works harder than normal to move oxygenated blood to your working muscles. When you engage in strenuous physical activity, your muscles need more oxygen than when you’re resting. This oxygen-rich blood then travels to the heart where it’s pumped out to your muscles, cells, and organs through the circulatory system. Some of this oxygen helps you continue breathing while other oxygen atoms are transferred into the bloodstream. Here’s the science behind it: When you inhale, your body draws in oxygen from the outside world, filling your lungs. If you have high cardiovascular endurance, you’ll be able to perform intense exercises and workouts longer than someone who has low cardiovascular endurance. This makes cardiovascular endurance a direct indicator of heart function, lung capacity, and muscle function. It is a measurement of your body’s ability to remove carbon dioxide and pump oxygen-rich blood to your organs. What Is Cardiovascular Endurance?Ĭardiovascular endurance is a measure of how well you can perform large-muscle, dynamic exercises at moderate to high intensity for an extended period of time (typically over 20 to 30 minutes). We’ll touch on what cardiovascular endurance is, how to measure it and how to improve it. Understanding cardiovascular endurance is the first step to being able to improve it. The waste products are eliminated in breath and perspiration.Whether you are training for a marathon, hiking up a mountain, or climbing the stairs to your bedroom, there is one thing you will need for all three activities: cardiovascular endurance. Aerobic metabolism: provides most of the energy needed for long, low-intensity, and oxygen-intensive workouts. Anaerobic metabolism (glycolysis): provides energy for short bursts of intense activity lasting several minutes. These two basic pathways are also broken down further, the three energy systems often referred to in exercise include: ATP-CP (anaerobic) energy pathway: providing short bursts of energy to pull up to 10 seconds long. In the simplest terms, the body can convert nutrients into energy in the presence of oxygen (aerobic metabolism) or in the absence of oxygen (anaerobic metabolism). The body converts food into fuel through different pathways. 1.2 Mechanisms of Energy Metabolism The goal of cardiovascular endurance training is to develop systems that produce energy to meet operational needs for the time they are required. If you have good cardiovascular endurance, you should be able to do an anaerobic activity that elevates your heart rate for a period of at least 20 consecutive minutes, such as jogging or swimming. In sports, it refers to the athlete's ability to sustain a prolonged exercise for several minutes, hours, or even days. 1.1 What is cardiovascular endurance? Cardiovascular endurance, also known as cardiopulmonary endurance, is the ability of the circulatory and respiratory systems to deliver oxygen to the body's organ tissues during physical activity.
