Are aerobic or anaerobic activities better for losing weight and staying fit? Aerobic gymnastics is a low-intensity and long-lasting activity that allows you to improve your cardiovascular, respiratory and metabolic functions. In fact, with constant training it gradually decreases the heart rate and increases the respiratory capacity (greater oxygenation of the tissues), in addition, with its low intensity, it burns the storage fats and sugars present in the blood and muscles. Aerobic sports are walking, running, cycling, swimming, cross-country skiing, the exercise bike and the treadmill, activities suitable for everyone, obviously under medical supervision and calibrating efforts based on age, weight and health conditions .
Benefits of aerobic activity
Among the great variety of plus there is certainly the increase in resistance and the multiplication of blood capillaries, which increases the flow of blood to the cells by increasing the size and number of mitochondria, enhancing the ability of cells to use oxygen and elevating the amount that the organism can use in a certain period of time. Gradually, heart conditions improve and, both during exercise and during the rest phase, the frequency decreases, making the heart stronger and more robust and increasing the amount of blood pumped with each beat. This activity is also essential for weight loss and for fighting and preventing cellulite. A regular program tones the muscles, promotes the reduction of blood pressure and heart rate, helps to reduce stress and control anxiety and depression, makes you lose weight, improves breathing and endurance.
Benefits of anaerobic activity
Anaerobic gymnastics is a power activity that involves carrying out an intense effort in a short period of time in which more oxygen is consumed than it is required to take. Since it puts the body in oxygen debt, its duration cannot be very prolonged and in addition it could cause the (unwanted) formation of lactic acid, the natural slag of muscle contraction.
The most common anaerobic sport is certainly weight lifting; followed by the fast run on 100 meters, heavy athletics, that is, involving jumps and throws, descent on skis and rowing. Squash is also on the rise. In general, with exceptions, these are sports to be practiced individually.
Today this type of gymnastics is practiced in physical culture and body building. It is characterized by sudden contractions of the muscles, which first burn glucose and then use fat; but when oxygen is no longer enough, they draw on the reserves of liver, kidney and muscle sugars. The advantages are the increase in muscle mass, the strengthening of the general musculature and the tendons with the consequent increase in strength help in the prevention of injuries. From an aesthetic point of view, the increase in muscle mass tones the body and sculpts its shape. From a health point of view, however, weight lifting improves metabolism, prevents injuries, strengthens bones by relieving the pain of osteoarthritis and increasing the bone mineral density of the spine, reduces stress and the risk of diabetes, because it improves the way sugar is metabolized.
