1. Sensitivity refers to the ability to quickly and accurately change the direction of body movement during activities. Sensitivity depends largely on neuromuscular coordination and reaction time, so we can improve human sensitivity by improving these two abilities.
2. Physical quality and athletic ability level: that is, the strength, speed, endurance, agility, flexibility and other qualities shown by the body in sports and the physical athletic ability such as walking, running, jumping, throwing and crawling.

3、? Physical fitness can be divided into physical fitness related to health and physical fitness related to sports skills. If you want to improve your health, you should focus on developing health-related physical qualities, such as cardiopulmonary endurance, flexibility, muscle strength, muscle endurance, body composition and so on. Physical abilities related to motor skills include speed, strength, sensitivity, coordination, balance and reaction.
4. Reaction time refers to the time to make a physiological response to some external stimuli. Quick reaction is the characteristic of excellent athletes in many events, especially in the starting stage of sprint, reaction time plays a great role. Health-related physical fitness and action-related physical fitness components overlap, such as cardiopulmonary endurance, muscle strength, muscle endurance, flexibility and body composition are very important for health and skill sports.
