| There are a wide range of differences in the intensity of exercise that individuals choose when they do physical exercise.Therefore,many studies are urgent to pay more attention to the individual differences in exercise intensity preference and exercise intensity tolerance.Therefore,it is necessary to discuss the individual's preference and tolerance in the intensity of exercise.However,previous studies have focused on the measurement of their physiological indicators,while ignoring the influence of psychological factors.In 2005,Ekkekakis,Hall and Petruzzello developed the Preference for and Tolerance of Exercise Intensity Questionnaire to measure differences in the preference and tolerance of exercise intensity between individuals during physical exercise.In foreign countries,this scale has been identified as a psychological assessment tool with good reliability and has been widely used.However,the domestic research on the intensity of exercise is mostly focused on physiology,from the psychological aspects to explore the exercise intensity preference and tolerance of the study almost no.Therefore,this study takes this scale as the starting point of the study,on the basis of exploring the background of the development of the scale and its application in foreign countries,this scale is revised into a scale suitable for the exercise group of college students in China,and used to investigate the characteristics of college students'exercise intensity preference and exercise intensity tolerance,in order to provide a basis We can also further understand the psychological reasons for college students not to exercise or exercise midway out,and provide an evaluation tool for PE teachers to understand the feelings of college students on the intensity of physical exercise.Firstly,this study translated and translated the original questionnaire PRETIE-Q,conducted semi-structured interviews with 150 sports majors and non-sports majors and 20 subjects who had just completed the power bike test,and formed a preliminary exercise intensity preference and tolerance questionnaire based on the translation content and interview results and combined with expert evaluation.Secondly,465undergraduates were predicted,and after project analysis and exploratory factor analysis,16 problems were not deleted,and after the prediction,the feedback of the subjects in the forecast was collected and sorted,and it was found that the subjects received a high degree of acceptance of the questionnaire and had good understanding ability.So a formal exercise intensity preference and tolerance questionnaire was formed.Thirdly,in order to test the reliability and validity of the questionnaire,it was finally determined that the questionnaire was divided into 4 dimensions,a total of 16entries.Compared with the original scale,the revised scale did not delete the entries,but combined with the language habits of our country,"muscle burning"changed to"muscle soreness"or"muscle acid swelling",the subject of modification is T3 and T13;In the dimension of the preference for low intensity,the problem with the topic of high strength preference,Then combined with the emotional susceptibility,the T12was modified accordingly,and in terms of the accurate expression of semantics,the T16 was modified and a total of 4 topics were modified.Finally,837 college students were tested using the revised questionnaire with good reliability,which was used to analyze the current situation and characteristics of college students'exercise intensity preference and exercise intensity tolerance.The main results of this study are as follows:1.The revised exercise intensity preference and tolerance questionnaire can be divided into two independent and interrelated questionnaires,namely:the Preference for and Tolerance of Exercise Intensity sub-Questionnaire,in which exercise intensity preference sub-questionnaire includes the preference for low intensity exercise and the preference for high-intensity exercise two dimensions,The exercise intensity tolerance sub-questionnaire included a low tolerance for strenuous exercise and a high tolerance of two dimensions for strenuous exercise.2.The exploratory factor analysis shows that the questionnaire extracts a total of4 factors,each of which has a load of>0.40 on the factors to which itbelongs,and the results of the verification factor analysis show that the first-order four-factor model is the optimal fitting model,and each fitting index is?~2/df=1.963<2,GFI=0.943>0.90,AGFI=0.921>0.90,CFI=0.964>0.90,TLI=0.956>0.90,RMR=0.046<0.05,RMSEA=0.049<0.05.The results show that the internal consistency coefficient of each sub-questionnaire and its dimensions is between 0.733 and 0.881,all above 0.7,which indicates that the consistency reliability of the questionnaire is good,The reliability of the retest is also more than 0.7,which indicates that the questionnaire has good reliability,the total amount of exercise of the physical activity grade scale is positively correlated with the exercise intensity preference score and the exercise intensity tolerance score,the questionnaire has a good validity correlation validity,after the questionnaire has been verified,the results show that the revised exercise intensity preference and tolerance questionnaire Requirements.3.Through the investigation of 837 college students'exercise intensity preference and exercise intensity tolerance,it is found that the present situation and development characteristics of college students'exercise intensity preference are as:Generally speaking,college students'exercise intensity preference score is low,tend to choose low intensity physical exercise,and exercise intensity preference score,preference score for low intensity exercise,There were significant differences in preference scores for high intensity exercise in gender,Professional category and grade.The boys'exercise intensity preference score,the preference score for low intensity exercise and the preference score for high intensity exercise were significantly higher than that of female students,the exercise intensity preference score of non-sports majors,The preference score for low intensity exercise and the preference score for high intensity exercise were significantly lower than those of sports majors,and sophomore students'exercise intensity preference score and preference score for low intensity exercise were significantly higher than that of the other three graders,The junior students'exercise intensity preference score and preference score for low intensity exercise were significantly higher than the freshman score,the freshman's preference for high-intensity exercise was much lower than the other three grade scores,and the sophomore grade's preference score for high-intensity exercise was significantly higher than that of the junior year score.The present situation and development characteristics of college students'exercise intensity tolerance are as:Low exercise tolerance score,and exercise intensity tolerance score,low tolerance score for strenuous exercise,high tolerance score for strenuous exercise,there are significant differences in gender and Professional category,male student's exercise intensity tolerance score,is higher than the female student to the strenuous exercise low tolerance score and to the strenuous exercise high tolerance score to score points by far,the non-sports class specialized student's exercise intensity tolerance score,obviously is lower than the sports class specialized student's score to the strenuous exercise low tolerance score and to the strenuous exercise high tolerance score.The exercise intensity tolerance score and the high tolerance score for strenuous exercise were only significantly different in the sophomore and junior grades of the grade category,and there was no significant difference in the grade variables between the low tolerance scores for strenuous exercise. |
