1, experimental method: through experimental operation and observation, the data of related variables are obtained, and the data are analyzed and explained through experimental design. Its advantages are controllable operation, reliable conclusion and high reproducibility of results, and the interference of some external factors can be eliminated. However, in practice, its research results are not necessarily universal, and better guidance and other research methods are needed.
2. Investigation method: refers to the research method of collecting data through interviews, questionnaires and observations. And analyze and explain the relevant variables to understand the respondents' views, attitudes and behaviors on a certain problem or phenomenon. Compared with the experimental method, the investigation method is characterized by relatively little intervention to the subjects, which can better reflect the true thoughts and behaviors of the subjects.
3. Observation method: directly observe related actions or behaviors, and record relevant data and factors that may play a role in behaviors. The advantage of observation method is that it can collect a large number of real data and obtain relatively real results without disturbing the behavior or state of the object. The disadvantage of observation method is that people's observation is often subjective and error, which is greatly influenced by individual differences of observers.
4. Simulation method: Computer simulation and simulation methods are used to simulate the movement environment and scenes, and data collection and data analysis of related variables are realized. The simulation method has some limitations, and its prediction results may be influenced by model setting, parameter setting, parameter evolution and verification methods.
5. Statistical analysis method: refers to a research method that uses statistical principles and methods to analyze and process the existing data in sports science research. Its purpose is to find the internal relationship between data through model prediction, classification and judgment of data, infer the overall characteristics represented by data, and support decision-making and behavior.
6. Literature research method: Through the collection and collection of relevant literature, systematic reading, analysis, comprehensive evaluation, induction and summary, relevant data and research results are obtained according to certain research objectives, so as to have a deep understanding of research topics or fields and expand knowledge, and provide theoretical support and guidance for sports science.
Overview of sports science research
Sports scientific research is a subject that explores and solves human sports, sports training and competitive performance through scientific methods. Sports science research mainly involves physiology, psychology, sports control, sports training, sports nutrition, sports medicine and other disciplines. Through various experimental designs and technical means, people can deepen their understanding and understanding of sports and improve their sports skills and performance.
The research fields of sports science mainly include the following aspects:
1, Exercise Physiology: To study the physiological responses of the human body during exercise, such as the static and dynamic physiological characteristics of cardiovascular, respiratory and muscle.
2. Sports psychology: study the psychological characteristics, behavioral characteristics and psychological bottlenecks of athletes.
3. Motion control: Study the formation, adjustment and coordination of motor skills.
4. Sports training: Study the methods and process of sports training, and explore the influence of sports training on physical, psychological and interpersonal relationships.
5. Sports nutrition: To study athletes' nutritional needs and reasonable diet.
6. Sports medicine: study the prevention and treatment of sports injuries and the impact of exercise on individual health.
7. Sports management: study the organization and management, marketing and sports law in sports field.
In sports science research, researchers need to give consideration to both theory and practice, and constantly optimize the research design by collecting, processing and analyzing a large number of experimental data to improve the reliability and accuracy of the research results. It is also necessary to strengthen inter-disciplinary cooperation and exchanges, explore potential problems and application prospects in the field of sports, and promote the continuous progress of sports scientific research.
