INTRODUCTION

Chronic fatigue syndrome (CFS) is also called chronic fatigue and immune dysfunction syndrome. This disease has now become a common disease in modern medicine. CFS is a severe sub-health state. It is a group of symptoms characterized by long-term continuous fatigue and non-specific symptoms such as inattention, memory loss, low fever, headache, sore throat, muscle and joint pain, sleep disturbance, and depression. Long-term work and study pressure, mental stress, lack of sleep, lack of exercise, introversion, and disharmony in interpersonal relationships are all causes of CFS. The current international diagnosis of CFS is based on the standard revised by the US Centers for Disease Control in 1994 (CDC-1994). This standard mainly includes continuous or recurring severe fatigue for 6 months or more and non-workout. And can not be relieved after rest. At least 4 of the following 8 symptoms are met: (1) Short-term memory decline or difficulty concentrating. (2) Sore throat. (3) Swollen lymph nodes in the neck or axilla. (4) Myalgia. (5) Multiple joint pain. (6) Headache. (7) Sleeping body. Being in a critical period of growth and development, while facing the pressure of entering a higher school and the long-term and tense pace of study and life, the student group is straightforward to become a CFS group. CFS can cause adolescents’ memory loss, decline in academic performance and severely affect their physical development and physical health. In addition, studies have shown that if CFS can be diagnosed and treated on time, it is more likely to recover.¹ However, the longer the duration, the more difficult it is to cure, which can cause immeasurable harm to the patient's physical and mental health. This ultimately leads to the occurrence of organic diseases. CFS can also cause sudden death of the body after heavy exercise. It can be seen that the harm of CFS to young people cannot be ignored. Monitoring and prevention of adolescent CFS groups are currently one of adolescent health management and promotion tasks. Young CFS is different from adults. They have their characteristics. According to the complexity of its symptoms, many variations must be considered in the diagnosis. Studies have found that fatigue, headaches, sleep disturbances, emotional problems, sound sensitivity, and cognitive difficulties are common symptoms of CFS in adolescents.

Chronic fatigue syndrome (CFS) is also called chronic fatigue and immune dysfunction syndrome. This disease has now become a common disease in modern medicine. Related experts have also proposed to improve the symptoms of chronic fatigue syndrome through exercise, but then there has also been a phenomenon of exercise resistance.² CFS patients can show a decrease in exercise capacity and peak oxygen intake compared with ordinary people. The heart rate will increase during sub-maximal exercise, and subjective fatigue will increase. Experts in the United States and the United Kingdom agree that gradual exercise therapy can improve the symptoms of chronic fatigue syndrome. Based on this, we designed a set of step-by-step exercise therapy to study its effect on patients with chronic fatigue syndrome.

METHOD

Research object

We selected 70 patients with chronic fatigue syndrome diagnosed and treated in a provincial People's Hospital.³ They all volunteered to participate in this experiment. We randomly divide them into two groups. There are 35 people in each group (Table 1).

Table 1
Basic information of the subjects.

	Test group	Control group	Total
Male/n	10	12	2
Height/cm	170.7±4.20	172.43±2.74
Weight/kg	69.77±5.1	72.25±7.21
Female/n	25	23	48
Height/cm	159.15±1.23	160.23±3.47
Weight/kg	58.14±3.11	55.12±4.27
Total	35	35	70
Average age	20.44±5.17

Diagnostic standards content includes the following two aspects:

1. Continuous or severe recurring fatigue of unknown cause. His medical history is not less than 6 months. The current patient's professional ability, ability to receive education, personal life, and social activity ability are significantly lower than before the illness. The patient cannot be relieved after rest.

2. Have at least four items out of the 8 items not listed at the same time: (1) memory or concentration decline; (2) sore throat; (3) neck stiffness or axillary lymphadenopathy; (4) muscle pain; (5) Multiple arthralgias; (6) Repeated headaches; (7) Poor sleep quality and not relaxing after waking up; (8) Myalgias after exertion.

Research methods

Physical examination

Perform physical examinations on all research subjects to understand their basic situation and avoid dangerous situations.⁴ This includes blood pressure, heart rate, respiration, electrocardiogram, and lung function, as well as questionnaires to screen out people with a history of sports injuries.

Questionnaire survey on quality of life and physical symptoms

1. The fatigue rating scale survey includes 14 items. Among them, eight items reflect physical fatigue, and six items reflect mental fatigue.

2. Comprehensive investigation of CFS status: 1) Improved Cornell Medical Index (CMI). We use the respiratory system, cardiovascular system, digestive system, skeletal muscle, and nervous system. Investigate the physical symptoms of the research subjects. 2) The questionnaire for a comprehensive assessment of the quality of life selects one dimension of social function. We evaluate the main social fields (education, occupation, economic life) and community social life of the research objects.

Experimental method

We randomly divided 70 subjects into two groups with 35 people in each group. The experimental group received gradual exercise therapy for half a year. The control group paid attention to rest according to the doctor's advice. Relax, but do not engage in particular physical exercise.⁵ The duration of the initial phase of exercise is 5 to 15 minutes. Exercise takes the midpoint of the heart rate reached during the submaximal exercise test as the average heart rate. Exercise intensity is based on this heart rate value.

The gradual exercise composed of aerobic capacity mainly uses the body's large muscle groups to exercise. Participants exercise under guidance every two days, taking into account the possibility of exercise resistance in chronic fatigue syndrome. If the patient has repeated illness or worsening symptoms, the time for the next exercise will be shortened or stopped accordingly.⁶ The subsequent exercise time is also reduced to the extent that the patient feels fit. Review their progress with each patient every four weeks to determine the exercise therapy plan for the next month. The patients and their family members recorded their sleep time before and after treatment.

Statistical processing

We used SPSS software to process all the data, and the results were expressed as mean±standard deviation. Paired t-test was used for pre-and post-control, and an independent-sample t-test was used for inter-group control. We use P<0.05 as the significance level. Under the condition of continuity and boundedness, we combine the wavelet kernel space matching method to match the associated features of sports wrong actions.⁷ Calculate the value of the sports machine vision information collection template in the boundary layer of the physical sub-region. Fix the ray direction in the template. We respectively obtain the coordinates of the intersection point of the feature movement frame of the wrong action image in sports. The Euler-Lagrange equation describes the three-dimensional data field of the wrong action in sports as:

(1) $$\boxed{\begin{array}{l}\frac{\partial \phi }{\partial t}=-\delta (\phi )\left[\theta \left({\lambda }_1{e}_1^{LBF}-{\lambda }_2{e}_2^{LBF}\right)+(1-\theta )\left({\lambda }_1{e}_1^{LGF}-{\lambda }_2{e}_2^{LGF}\right)\right]+\hfill \\ \upsilon \delta (\phi )div\left(\frac{\nabla \phi }{|\nabla \phi |}\right)+\mu \left({\nabla }^2\phi -div\left(\frac{\nabla \phi }{|\nabla \phi |}\right)\right)\hfill \end{array}}$$

The calculation formula of $e_1^{LBF},e_2^{LBF},e_1^{LGF},e_2^{LGF}$ is:

(2) $$\boxed{\{\begin{array}{l}{e}_1^{LBF}={\displaystyle {\int }_{\Omega }{K}_{\sigma }}(y-x){\left|I(x)-f_1(y)\right|}^{2}dy\hfill \\ e_2^{LBF}={\displaystyle {\int }_{\Omega }{K}_{\sigma }}(y-x){\left|I(x)-f_2(y)\right|}^{2}dy\hfill \end{array}}$$

(3) $$\boxed{\{\begin{array}{l}{e}_1^{LGF}={\displaystyle {\int }_{\Omega }{K}_{\sigma }}(y-x){\left|I^G(x)-f_1^G(y)\right|}^{2}dy\hfill \\ e_2^{LGF}={\displaystyle {\int }_{\Omega }{K}_{\sigma }}(y-x){\left|I^G(x)-f_2^G(y)\right|}^{2}dy\hfill \end{array}}$$

We use the local binary fitting method for sports machine vision information collection and motion vector library reconstruction.⁸ The regional pixel information of sports images under computer vision is:

(4) $$\boxed{L=J(w,e)-{\displaystyle \sum _{i=1}^N{a}_i}\left\{w^T\phi \left(x_i\right)+b+e_i-y_i\right\}}$$

a_i represents the configuration sequence of the standard action. J (w, e) is the repeated pixel point of the sports position under machine vision. φ(x_i) is the contour feature distribution function in the standard motion vector library.

RESULTS

Cornell Medical Index (CMI) scoring results showed that the experimental group was treated with eye and ear scores (A), musculoskeletal system scores (E), nervous system scores (F), fatigue scores (G) Significantly better than before treatment (P<0.05). However, there was no significant change in the points of the respiratory system (B), cardiovascular points (C), and digestive system (D). There was no significant change in all indicators of the control group.

DISCUSSION

The pathogenesis of CFS is more complicated. Most people believe that chronic fatigue syndrome may result from a neuroendocrine-immune network disorder caused by multiple factors such as viral infection and stress. As the cause and pathology of CFS are not very clear at present, an effective treatment method has not been found clinically.⁹ However, the currently used treatment methods such as antiviral, immune enhancement, hormone supplementation, and anti-depression have not obtained apparent effects. This is a mainly symptomatic treatment to relieve symptoms. Sports medicine experts recognize that exercise can improve the symptoms of chronic fatigue syndrome.

The experimental results show that the step-by-step exercise method can effectively improve the sleep of patients. The possible mechanism is that the 24-hour circadian rhythm adjustment ability of CFS patients is lacking. The internal circadian rhythm does not match the 24-hour natural rhythm, making the body clock rhythm prolonged. Increased sleep time and decreased sleep quality have caused daytime fatigue, insomnia at night, and cognitive dysfunction. Vigorous unplanned exercise may further disrupt the biological rhythm. The gradual exercise therapy can enhance the body's ability to regulate circadian rhythms.

CONCLUSION

The form of exercise we choose to walk is also a daily exercise. This will not cause the human body to produce an initial stress response. And gradual exercise can also improve the sleep phase so that patients can improve sleep efficiency and fully recover their physical strength. In addition, research data shows that the blood circulation of people who exercise moderately is 2 times higher than that of ordinary people. This can provide sufficient oxygen and nutrients to the brain tissue. This can make the brain work more freely and think more quickly.
