At present, there are no suitable indicators for the determination of some aspects of ability. For example, psychological factors can only be tested through questionnaires. Some questions are asked for the respondent to answer and score according to the answer sheet. But this method is repeatable. Poor, the results are not necessarily very true. No matter how adaptable it is, it is difficult to find a suitable indicator to test.

　　 Therefore, the current test indicators only include body shape, body function, and body quality. Aspects.

　　 Specifically, taking an adult aged 20 to 39 years as an example, the index reflecting body shape is the standard weight for height, that is, the weight range corresponding to a certain height; the index reflecting body function is The vital capacity that reflects the volume and expansion capacity of the human lung, as well as the step test that reflects the level of function of the cardiovascular system of the human body; the index that reflects the physical fitness is the grip strength that reflects the strength quality, push-ups (male), 1 minute sit-ups (female), vertical Jumping; flexion qualities reflect forward flexion; sitting qualities reflect reaction time; reflect balance abilities reflect closed eyes and stand on one foot.

　　The situation of young children is different, test indicators Only includes two types of body shape and quality. The indicators reflecting body shape are height and standard weight. The indicators reflecting physical fitness are 10 meters turning back, standing long jump, tennis throwing long distance, continuous jumping of two feet, sitting forward bending. 6 items including balance beams.

　　 In order to allow ordinary people to understand the strength of their physical activity ability and master the appropriate activity intensity before participating in fitness exercises, some European and American scholars have proposed a simple assessment model , That is, the activity index. This index evaluates the basic situation of individuals who usually participate in exercise from three aspects: exercise intensity, duration, and exercise frequency (Table 3-1), so that people know how much exercise they need to participate.

　　Everyone can calculate their own activity index based on their daily activities: total score=exercise intensity score×duration score×exercise frequency score to understand their physical activity ability, and choose their own according to the results Exercise method.
