Effect Of High Intensity Interval Training On Cardiopulmonary Function And Body Composition Of Presenium Runners

With the advancement of population aging and lifestyle changes,the importance of developing regular exercise habits before entering old age is becoming more and more obvious The early stage of old age is a critical period for entering old age The physical health of the early stage of old age is the guarantee of the life health and quality of life of the elderlyIn this study,early-aged 45-59 years old runners were used as subjects to design and implement a high-intensity interval training program suitable for this group,hoping to improve the physical fitness of early-aged runners,build a solid physical foundation for the group to enter the elderly stage and improve athletic ability After 8 weeks of HIIT intervention,this thesis analyzes and discusses the changes of cardiopulmonary function and body composition of pre-elderly runners,and then discusses the principle of HIIT ’s influence on cardiopulmonary function and body composition of pre-elderly runners,so as to provide theoretical basis for scientific fitness of pre-elderly runners and suggestions and references for different groups of people to use HIIT fitnessThis research process uses the questionnaire survey method,experimental method and mathematical statistics method Firstly,the subjects were recruited in the form of online questionnaires,and 30 eligible subjects were selected Then,all subjects were tested for pre-experimental indicators,including the subjects ’ maximum oxygen uptake,vital capacity,quiet heart rate,weight,BMI,fat-free weight,body fat mass,muscle mass,fat mass and muscle mass of both lower limbs,etc,and then the subjects were subjected to an 8-week HIIT intervention Finally,all subjects were tested for post-experimental indicators,and data were collected for comparative analysis In this study,Shapiro-Wilk test and Jarque-Bera test were used to determine whether the two groups of data obeyed normal distribution The data of pre-test and post-test were analyzed by paired sample t test Pearson correlation coefficient was used to analyze the experimental data In this study,the difference between the data was significant when the p value was less than 005The conclusions of this study are as follows :1 After 8 weeks of HIIT intervention,the cardiopulmonary function of pre-elderly runners was significantly improved Among them,the increase of maximum oxygen uptake was the most obvious,followed by vital capacity,while the quiet heart rate did not change significantly It is confirmed that HIIT can meet the training needs of this group for running HIIT can maintain its short-term and efficient characteristics in improving aerobic endurance2 HIIT can effectively reduce the body fat mass of early-aged runners,increase muscle mass,and increase the body ’s fat-free weight It is an effective means to delay the aging process of the human body3 8-week HIIT intervention can improve both body composition and cardiopulmonary function The two are closely related Reasonable muscle fat reduction can improve cardiopulmonary function,and the improvement of cardiopulmonary function can promote the change of body composition...
