Objectives: The objective of this study is to explore the effect of oral creatine on the anaerobic exercise ability of soccer players. Methods: Twenty healthy football players in five football teams were selected as the study participants, and they were randomly divided into the observation group and control group, each of which was 10. The football players in the control group were given glucose at a rate of 5 g/time, and the members of the observation group were given creatine glucose at a rate of 5 g/time and the supplementation of the two groups was 5 g × 4 when they have their meals and before bedtime. During the period, the training of the football players is normal. Moreover, the blood lactic acid and oxygen-free work of the two groups were compared. Results: After having oral creatine, the peak of oxygen-free work of the observation group was significantly increased, which was obviously superior to the control group without oral creatine. The difference was statistically significant (P < 0.05). After having oral creatine, the lactate level of 3 min in the observation group was significantly lower than that in the control group after exercise, and the difference was statistically significant (P < 0.05). Conclusions: After the oral creatine is taken orally, the peak of the oxygen-free work, the explosive force and the action quality of the football player can be improved. Significantly, it can increase the speed of movement fatigue recovery and it is worth popularizing.

Objectives: The objective of this study is to explore the relationship between college students' emotion management ability and mental health. Methods: A total of 1000 college students from four universities in our city were selected as the object of the study. The emotion management ability of 1000 college students was analyzed by means of questionnaire, and the mental health status of college students was measured with symptom checklist (SCL)-90. The average scores of the five dimensions of college students' emotional management ability are classified as follows: Controlling negative vent >rational regulation >seeking outside support >controlling negative suggestion >positive remedy. Results: The results showed that there were obvious negative correlations between the three factors and the SCL-90 factors, such as the rational control of college students, the control of negative implications, and the control of negative venting. However, there is only a negative correlation between college students' seeking outside help and interpersonal, paranoid, psychotic, and depressive factors. Positive remedies were negatively correlated with the symptoms of compulsion, psychosis, and depressive factors, while positive remedies and paranoia factor and hostile factor are obviously related. Conclusions: In the investigation of college students' emotional management ability, the five dimensions are closely related to their mental health status. Therefore, we should pay attention to the cultivation of college students' emotional ability and encourage them to participate in some meaningful activities to improve their mental health.

Objectives: To explore the multiple factors of neuropsychology in elderly patients with depression. Methods: 64 elderly patients with depression were selected as individuals. The Geriatric Depression Scale (GDS), neuropsychological scale score, and family support scale were used to analyze multiple factors of neuropsychology in elderly patients with depression. Results: Through GDS, neuropsychological scale, and family support scale, we can see that there is cognitive impairment in elderly patients with depression. It is closely related to the following three factors: the economic capacity of the family, their health status, and family support level. These factors play an important role in the depression of the elderly and are the main causes of depression in the elderly. Conclusions: There are many neuropsychological factors affecting depression in the elderly. In the prevention of the occurrence of depression in the elderly, the prevention of physical diseases should be done in time, and the harmonious family relationship should be maintained. At the same time, the economic situation of elderly families should be improved.

Objectives: The objective is to study the characteristics of energy consumption and substrate metabolism during exercise. Methods: Sixteen female college students in a university in Wuhan province were selected as the control group, and 16 male college students were selected as the research group. The two groups of car exercise experiments with different intensity were carried out, and the energy metabolism of the body was analyzed by the gas substitution method. Results: Compared with the control group, the total energy consumption in the observation group was significantly higher, and the difference between the two groups was statistically significant (P < 0.05). The percentage of fat in the control group was significantly higher than that in the observation group (P < 0.05). There was no significant difference in fat oxidation between the control group and the observation group under the same exercise intensity (P > 0.05). Compared with the control group, the observation group was significantly higher glucose oxidation, and the two groups had a statistically significant difference (P < 0.05). Conclusions: In the process of exercise, the proportion of female fat supply is significantly higher than that of men, and the total energy consumption in the process of male exercise is more than that of women.

Objectives: The objective of the study was to discuss the design method of medical image three-dimensional (3D) visualization system based on magnetic resonance angiography (MRA) data. Methods: Using 3D visualization of the carotid artery as an example, the three-position reconstruction algorithm on the basis of volume rendering was discussed. Moreover, if 3D carotid artery is extracted, based on this, we could combine Visualization Toolkit and Image Segmentation and Registration Toolkit with it to construct a 3D visualization system of medical images based on MRA data using C++. Results: The 3D visualization system of medical image data can be read on the MRA based on Digital Imaging and Communications in Medicine images and can be displayed completely. At the same time, a series of interactive operations can be carried out on the 3D image, and three-position blood vessel segmentation and enhancement on the basis of volume rendering can be realized. Conclusions: The medical image 3D visualization system based on MRA data can read and display 3D images and can realize a series of interactive operations, which can achieve better blood vessel enhancement effect and carotid artery extraction. It has important function and significance for a three-bit visualization of medical image.

Objectives: To apply the acupuncture and moxibustion to the treatment of patients with depression and study the serum brain-derived neurotropic factor (BDNF) level, C-reactive protein (CRP), and zinc level in the patients. Methods: Thirty-five patients with depression treated in our hospital were selected as the research individuals, and they were randomly divided into the control group and the observation group. Seventeen patients in the control group were treated with head massage and 18 patients in the observation group were treated with acupuncture. The levels of BDNF, CRP, and zinc were measured and recorded by enzyme-linked immunosorbent assay. Results: The levels of BDNF in serum BDNF in the control group were significantly higher than those in the control group, and there was a significant difference between the two groups in serum BDNF levels (P < 0.05). Compared with the control group, the CRP decreased significantly in the observation group, and there was significant difference in the CRP between the two groups (P < 0.05). The level of zinc in the observation group was significantly lower than that of the control group, and there was a significant difference in the level of zinc in the two groups (P < 0.05). Conclusions: The treatment of acupuncture and moxibustion can effectively reduce the level of serum BDNF in patients, the level of zinc, and CRP, which has a certain value of research.

Objectives: The aim of the study was to explore the association between different time periods and acute myocardial infarction. Methods: In the study, 124 patients with coronary heart disease were selected as the study participants, and they were divided into observation group and control group averagely, with 62 patients in each group. The control group chose not to exercise, the observation group chose to exercise, and they were divided into morning exercise group and the evening exercise group. The exercise information of patients was collected by the questionnaire, and the relationship between different sports intensity, different movement frequency, duration of different movement, and movement in different time periods was compared with that of acute myocardial infarction. Results: The corrected odds ratio (OR) value of the observation group and the control group was 0.68, and the incidence of acute myocardial infarction was lower in the case of exercise. Different exercise intensity, different exercise frequency, different exercise duration, and different time periods have an important impact on the occurrence of acute myocardial infarction. If the exercise intensity is high, the frequency is high, and the duration is long, they can prevent myocardial infarction. Compared with the control group, the observation group morning exercise group and evening exercise group correction values of OR were 0.61 and 0.57, the difference is distinct, and the difference was statistically significant (P < 0.05). Compared with the morning exercise group, the risk of acute myocardial infarction was 0.92. Conclusions: The risk of acute myocardial infarction in patients with coronary heart disease with high exercise intensity, high frequency, and long duration was lower. Moreover, an exercise in the morning and evening had a similar protective effect on the prevention of acute myocardial infarction.
