The combination of various exercise methods can improve physical fitness. Physical fitness refers to the ability that the human body has enough energy to engage in daily work, enjoy leisure activities and adapt to emergencies at the same time, including "healthy physical fitness" and "skilled physical fitness". The measurement indexes of "healthy physical fitness" include muscle strength, muscle endurance and cardiopulmonary endurance, while the measurement indexes of "skilled physical fitness" include sensitivity, balance, coordination, speed, explosive force and reaction time. Generally speaking, in terms of exercise effect, it can be roughly divided into three categories: one is to exercise cardiopulmonary function and endurance, such as long-distance running; Second, strength exercises, such as parallel bars, dumbbells, and professional equipment for exercising strength in the gym; The third is flexibility exercise, such as yoga, bodybuilding and gymnastics.
Ball games are comprehensive sports that combine various fitness functions. Endurance, strength and flexibility can all be exercised, but other sports methods may only focus on certain aspects. Therefore, cardiopulmonary function and endurance are well exercised, but strength and flexibility are slightly worse. So you can do more simple stretching and strength exercises at ordinary times; The same is true for people who like swimming. You can do some strength exercises appropriately, so as to achieve good results.
The main principle of exercise is to give priority to aerobic exercise, strengthen cardiopulmonary function and endurance exercise, and properly exercise flexibility and strength. So you can choose two or three exercise methods according to your own interests and combine them to exercise.
People who often do only one kind of exercise should try to do some sports that they are not good at in order to achieve the goal of overall fitness.
