Physical Activity And VO₂max Of College Students Relationship Research

With the progress of science and technology,the development of civilization,the continuous improvement of living conditions and the gradual formation of a convenient and beneficial social environment such as travel mode,the problems of insufficient physical activity and the decline of physical health of college students are highlighted.How to effectively enhance the physical health of college students has become one of the key points of our country’s education work.Through the methods of literature review,questionnaire survey,testing,experiment and mathematical statistics,this paper takes the ordinary college students of China University of mining and technology as the investigation,test and experimental objects,carries on the physical activity survey and the maximum oxygen uptake test,and analyzes different gender and major The differences between VO₂max and physical activity of college students were analyzed.The influencing factors of VO₂max and physical activity were discussed.The correlation between physical activity and VO₂max was studied.The related factors of VO₂max of college students were analyzed by multiple linear regression.Finally,through the experimental intervention of 8-week exercise prescription,the influence of physical activity on VO₂max was further verified:（1）49.5%of the ordinary college students in China University of mining and technology are in the low level of physical activity,38.3%in the medium level of physical activity,and 12.2%in the high level of physical activity;77.3%of the college students sit in more than 6 hours a day,and 49.8%of the college students lack sleep.From the perspective of gender,the overall level of physical activity of male college students is better than that of female college students;from the perspective of grade,with the increase of College Students’grade,the level of physical activity gradually decreases;from the perspective of professional type,there is no difference in the physical activity of college students.（2）35.6%of the students whose VO₂max was lower than the normal level.From the perspective of gender,the overall VO₂max of male college students is significantly better than that of female college students;from the perspective of grade,there is a significant difference in the VO₂max of different grades,and the lower grade is better than the higher grade;from the perspective of professional categories,there is no difference in the VO₂max of different professional categories.Height,weight,maximum heart rate and VO₂max have significant correlation,but BMI and VO₂max have no correlation.（3）Maintaining high physical activity level can improve the maximum oxygen intake level of college students,improve their aerobic endurance and improve their physical health;the maximum oxygen intake level of long-term low-level students will show a downward trend;although the level of middle physical activity has a certain effect on the improvement of the maximum oxygen intake level of College Students,the effect is not significant.From the aspect of energy consumption,the high-intensity physical activity items of college students have significant effect on the improvement of maximum oxygen intake level,while other intensity physical activities have no significant effect on the maximum oxygen uptake.Healthy running intervention with 75%maximum heart rate intensity at 8 weeks can effectively increase the maximum oxygen intake level and reduce body weight of college students.（4）The relationship between VO₂max and height,weight,maximum heart rate,weekly high-intensity physical activity and weekly total physical activity was analyzed by multiple regression analysis.The regression equation was as follows:VO₂max of male college students=-26.944+0.191×height+0.199×maximum heart rate+0.002×weekly high-intensity physical activity;VO₂max of female college students=-26.944+0.191×height+0.199×maximum heart rate+0.002×weekly high-intensity physical activity VO₂max=-62.671+0.508×height-0.329×weight+0.177×maximum heart rate+0.002×weekly meet.（5）8 weeks exercise prescription intervention can effectively improve the level of maximal oxygen uptake and reduce weight of college students.This paper has 10 pictures,27 tables and 99 references.
