Secondly, an important difference between marathon training and health preservation is the diversity of exercise intensity. There are intermittent running aimed at increasing oxygen intake, rhythmic running aimed at raising lactate threshold, marathon pace running aimed at adapting to competition, long-distance running and jogging aimed at exercising endurance. In order to achieve the goal of each training, the quantification and division of intensity must be the key issue. In training and competition, the perception of intensity is the primary problem to ensure safety and avoid injury.
Furthermore, there is a certain foundation for running age. The decline of physical fitness will always be reflected in some indicators. After long-term research, athletes find that the physical condition of ordinary runners will change obviously after the age of 35, so it is easier to realize marathon before the age of 35. This decline in human body makes runners feel the most obvious decline in aerobic metabolism during running, which directly affects the endurance of runners. If you say that you can still see the endurance of runners in their seventies at this time, Bian Xiao can only say that this is an example, and the data depends on the average age.
You know, to carry out marathon training, we must first ensure the amount of exercise. Because, in many cases, high intensity means that the amount of exercise can not be guaranteed, so that the endurance of a large number of sports can not be improved. In low-intensity and high-intensity aerobic training, the body has enough time to adapt, enhance the adaptability and endurance of nerves, muscles and various tissues, improve technical coordination and economy, and avoid high-intensity damage to the body.
