Description

Joint strength test and resistance training integrated instrument

Technical Field

The invention belongs to the field of health training equipment, and particularly relates to an integrated instrument for joint strength testing and resistance training.

Background

In order to respond to and further realize the large target of the national 2030 health Chinese plan and the body-medical fusion, the accurate exercise intervention on different populations (general population, patients and athletes) is a small step in realizing the core key of the body-medical fusion to prevent and control diseases through scientific exercise. When the exercise intervention is implemented, the exercise intervention is implemented through three aspects of frequency, strength, time and exercise mode, namely, control of aerobic and anaerobic exercise (VO2 max% and HRmax%), resistance control (1 RM%) of muscle strength training and control of flexibility, and the body joint strength is accurately measured, so that the size of joint training resistance is accurately controlled, and the method is a key point for realizing muscle resistance training. Generally, we use 1RM to represent the maximum force of a certain joint of the body, so that in the exercise training and the exercise intervention, the maximum force 1RM of the joint needs to be accurately measured and captured, and then 1 RMx%, namely: 40 percent, 50 percent and 60 to 100 percent of the maximum strength (x is a proper percentage) are used for accurately controlling the strength of the joint strength resistance training.

When determining exercise intervention, the strength of resistance training more suitable for specific people or individuals is used for implementing interventional exercise, however, no fixed scale is available for measuring the load of resistance training until a large value is used, and numerous researches show that the strength of muscle strength training used during exercise can directly influence the physiological metabolic mode of human bodies and further indirectly change the physiological state of the human bodies, and the benefits and effects brought to the bodies by the muscle strength training with different resistance strengths are different. Most people lack related training knowledge in the training at the present stage, and the link of controlling the exercise intensity is neglected, so that a plurality of negative effects occur in the muscle resistance training; muscle damage caused by too high intensity, poor or even no effect caused by too low intensity, and intensity control is more important when the exercise intervention of a patient is carried out, especially for the muscle resistance training of cardiovascular patients, and the risk coefficient is increased caused by too high intensity. For the exercisers, the resistance training of different muscle strengths has different proportions of the muscle fiber types of the formed muscles and different proportions of the muscle fibers owned by different sports, so that the scientific and reasonable control of the load of the training resistance is very important during the muscle strength training.
