The word ‘cardio’ is most likely one of the principal words you hear when you first begin with a workout program. You realize that cardio is a fundamental part of any exercise, regardless of whether you need to cut down fat, gain healthy muscle mass, or simply remain toned.
It is recommended by the Health authorities to do at least 150 minutes of cardio exercise per week to reduce health risks. Based on the fitness goals, the intensity of these cardio programs may be adjusted. If you need to lose a considerable measure of weight (in excess of 5 percent of body weight) or potentially keep it off, you may need to accomplish over 300 minutes of moderate-intensity physical activity a week and that does exclude weight training. Getting a more profound comprehension of cardio exercise might be what you have to get inspired to do it somewhat more frequently.
The Definition of Cardio?
The term cardio comes from the term “cardiovascular” and primarily used to refer to the cardiovascular workout. The term “cardiovascular” relates to the heart and blood vessels (including arteries, veins, and capillaries). When talking about cardiovascular health, we simply refer to the health of the heart and blood vessels, also known as the circulatory system. Having said so, it might be quite evident cardio is a type of workout that primarily involves the circulatory system.
Apart from that cardio is often interchangeably used with Aerobic exercise. This is due to the fact that the mechanism used to generate energy to burn surplus calories or fat depends on the aerobic energy-generating process.
The term aerobic refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.
Therefore, Cardio workouts involve a rhythmic activity that raises your heart rate into your target heart rate zone delivering more oxygen to the muscles. It is the zone where you’ll burn the most fat and calories using the surplus oxygen extracted from the blood.
Cardio Workout and the Aerobic Process Explained
- Oxygen Delivery
Breathing increases during aerobic exercise to bring more oxygen into your body. Once inside your body, the oxygen is processed by the lungs, moved to the circulatory system where it is conveyed by red blood cells to the heart, and afterward pumped by the heart to the practicing muscles by means of the circulatory framework, where it is utilized by the muscle to create energy.
- Oxygen Consumption
“Oxygen consumption” varies from person to person. Athletes or Conditioned individuals have more elevated levels of oxygen utilization than less conditioned people (normally people who are fat or does less activity) because of biological evolution in the muscles resulting from training. For instance, a less conditioned individual may have a maximal oxygen utilization of 35 milliliters (ml) of oxygen per kilogram of body weight every moment (ml/kg/min), while an athlete may have a maximal oxygen utilization up to 92 ml/kg/min.
- Burning Fat
A higher level of fat is burnt out during oxygen consuming activity (cardio exercises) than during anaerobic exercise. Fat being denser than carbohydrate (fat has nine calories for every gram and carbohydrate has four), takes a higher amount of oxygen to burn the fat. During cardio workouts, more oxygen is conveyed to the muscles than during anaerobic exercise, thus it follows that a higher level of fat is burnt during aerobic exercise when more oxygen is accessible. At the point when less oxygen is available like during anaerobic exercise, a higher level of carbohydrate may be shredded as energy.
This does not mean that during a cardio workout does not extract energy from the carbohydrates. Unlike in anaerobic exercise, the cardio workout involves extracting energy from fat as well as carbohydrates.
