Effects of Different Physical Fitness Exercise Prescriptions on Function of College Students' Heart Pump Guo Hong, Huang Yushan, Deng Shuxun College of Sports Science, South China Normal University (Guangzhou 510631, China) and comprehensive development of physical fitness as the main body (comprehensive) exercise prescription, exploring different types of fitness exercise prescriptions The impact on college students' heart function provides experimental data and physiology for promoting the reform of college extracurricular exercises and the scientificization of national fitness. The experimental results showed that after 8 weeks of exercise prescription exercise, the experimental group of college students had decreased HR, stroke volume (SV), stroke index (SI), per-central output (CO), and index (CI). Significantly increased; mean systolic blood pressure (MSP), mean diastolic blood pressure (MDP), mean arterial pressure (MAP) decreased to varying degrees; left ventricular effective pump force (VPE) and index (VPEI) increased. It shows that the three kinds of fitness exercise prescriptions can significantly enhance the college students' heart function. Comparing the fitness effects of three exercise prescriptions, endurance exercise prescriptions have the best effect on improving heart function. Comprehensive exercise prescriptions also have a certain effect on improving blood stasis function, but the fitness effect is more comprehensive. The results of the two heart pump function tests of the male and female college students in the control group indicated that female college students had poor enthusiasm for participating in extracurricular physical exercises, and they were more likely to experience decline in physical function. They should strengthen their awareness of fitness and participate in physical exercise. This study shows that the use of fitness exercise prescriptions in extracurricular sports activities for college students, fitness conditions are simple, fitness techniques are scientific, fitness effects are obvious, and has certain advantages. 1 Research Objectives Since the concept and practice of exercise prescriptions in the 1950s into fitness training, countries around the world, especially the economically developed countries, have conducted extensive research on the theory and practice of exercise prescriptions, and have been widely used in scientific fitness exercises. China’s research on exercise prescriptions started late, but it has also made great progress in the past decade. 121. Especially with the promulgation and implementation of China’s national fitness program outline, the people’s fitness awareness has continued to increase, and the fitness exercise has become more scientific. The demand for continuous improvement, how to use exercise prescriptions to guide scientific fitness exercises is an important part of current research in this field. The strength of the heart pump function is an important sign of human health, but the study of the effect of exercise prescription on the function of college students' heart pump has not been reported. The aim of this study was to develop fitness exercise prescriptions with different body qualities in the extracurricular exercises for undergraduates, to observe the effects of different types of fitness exercise prescriptions on the function of heart pumps, and to compare their different fitness effects. Through this study, we will provide experiments for accelerating the reform of extracurricular sports exercises in colleges and universities and the scientificization of national fitness. 2 Subjects and Methods 21 Subjects The subjects of this experiment were 84 students (37 males and 47 females) in the Department of Biology, Mathematics and Economics of South China Normal University. They were randomly divided into 3 experimental groups according to gender. One control group. Subjects of the experiment were funded by the school's physical examination fund project: National Institute of Physical Education and Research, National School Sports Health Research Plan “Ninth Five-Year Plan†4-2015 China Academic Electronic Electronic examination, all qualified, no cardiovascular disease. The basic conditions of the experimental subjects are shown in Table 1 Situation (X ± S) Group Gender Number Age (years) Height (cm) Weight (kg) Strength Group Endurance Men and Women Endurance Men and Women Full Men and Women Control Group Men and Women 22 Test Methods 221 Fitness Exercise Prescription Each exercise prescription consists of three parts: Preparation section (5 minutes), basic section (30 minutes), and finishing section (minutes) The first set of exercise prescriptions is based on strength exercises (referred to as the strength group). The main exercise content is: pass solid ball exercises, two pairs of backs Pour solid balls, in situ abdomen jumps, left and right foot hops, two jumps, etc. The second set of exercise prescriptions is mainly to enhance cardiopulmonary function (referred to as endurance group), the main practice content is: all kinds of skipping rope, game paste ointment , group dance, etc. The third set of exercise prescriptions is based on the development of comprehensive physical fitness (referred to as comprehensive group), the main content of the exercise : Responsiveness enhancement game, frontal throwing solid ball, one-legged jumping obstacle of right and left foot, 4X10m round-trip running, 400m variable speed running, etc. The amount of exercise of fitness exercise prescription varies according to gender.Set exercise intensity: the average part of average heart rate remains at 120 ~140 beats/min.10 seconds of pulse are measured immediately before the exercise prescription exercise, immediately after the preparation exercise, in the basic part (twice), and after the finishing exercise to control exercise intensity.222 Experimentation Each exercise group performs a set of fitness exercises. Exercise prescriptions: Exercise 3 times a week for 40 minutes each time for 8 weeks The control group studied and lived routinely.All subjects were tested before and after exercise prescription exercises.The tests were conducted in a dedicated testing room and used the same The instrument was in charge of the test, and the subject took a break after entering the test room, taking a seat to measure the blood pressure, and then testing with the AZN-type cardiovascular function tester manufactured by the Institute of Intelligent Machinery, Chinese Academy of Sciences. The sensor probe is placed on the arterial pulse of the left hand and the pulse signal is input to the XDH-type electrocardiograph by the sensor Record the pulse graph, then measure the height and weight, measure and calculate the pulse pattern according to the prescribed method, and enter the relevant parameters, including height, weight, and blood pressure, into the computer, and automatically print the heart pump function according to the program. Item index parameters.All data using Microsoft Excel t test and analysis of variance.3 Experimental results and analysis 1 fitness exercise prescription before and after exercise HR (pulse, times / min), SV (stroke volume, ml / beat), SI (per Stroke index, ml / beat / square meter), CO (cardiac output, liter / min), CI (heart index, liter / min / square meter) changes 311 male college students before and after fitness exercise prescription HR, SV, SI, Changes in CO and CI The pulse rate and heart rate of healthy people are the same, and heart rate is an important indicator of cardiac function. The test results showed that after the exercise, the endurance group and the comprehensive group of male college students significantly reduced the VPEI (effective left ventricular pump power index, kg/min/m2) and EWK (the left ventricular myocardial energy efficiency) after exercise. 331 Changes in VPE, VPEI and EWK before and after exercise of male college students in physical exercise prescription Left ventricular effective pump force is a valuable index to evaluate left ventricular function, and its value reflects how much the blood in the left ventricle is obtained when myocardial contraction occurs. The pumping force was significantly enhanced (Table 6) The effective utilization of left ventricular myocardial energy mainly reflected the functional state of the myocardium, and its high value indicates that the cardiac muscle has a good functioning state. The test results suggest that the three experimental groups have improved cardiac function after exercise, and the energy efficiency is improved. Table 6 Changes before and after exercise for men's college students' exercise prescriptions (X Shi S) Group Time Strength Group After-exercise After-endurance Group After-exercise After-exercise After-group After-exercise Before-control After-exercise Group After-exercise Table 7 Table for female college students Before and after exercise Group Strength Group After-exercise After-endurance Group After-exercise After-exercise Group After-exercise After-exercise Group After-exercise After-exercise 332 Female college students VPE, VPEI, EWK Changes after exercise VPE increased, with an increase in the endurance group being very significant (Table 7) EWK was also the most significant increase in the endurance group. In the control group, except for the EWK, the other two indicators decreased. It is suggested that the function of the heart pump of under-exercise female college students is apt to decline, and more attention should be paid to exercising. 34 Comparison of each index between the experimental group and the control group will be carried out before and after the exercise prescription exercise indicators of the experimental group compared with the control group, the results show that before the male college students only strength group MDP was significantly higher than the control group The indicators were not statistically significant. The results showed that there was no significant difference between the experimental group and the control group in the r9 fitness exercise prescription forging group and the pre-experiment cardiovascular function. The comparison of the physical exercise forging Mt with the experimental group and the control group found that the MDP of the men's strength group was lower than that of the control group, and a significant decrease of MAP compared with the control group suggested that the exercise of the strength group improved blood vessel function (Table 4). After the exercise, the quiet heart rate of the endurance group was lower than that of the control group, and the CO was significantly higher than that of the control group, indicating that the exercise of the endurance group had a stronger effect on the pump function than other exercise prescriptions (Table 2). The group comparison showed that only HR in the endurance group was significantly higher than that in the control group before exercise, while the resting heart rate in the endurance group after exercise was lower than that in the control group, and all the four indicators of SV, SI, CO, and CI in the three experimental groups were significantly higher than those in the control group. In the control group (Table 3), VPE and VPEI in the strength group and comprehensive group were significantly higher than those in the control group (Table 7). The MDP in the endurance group was significantly lower than that in the control group (Table 5). Heart function has a good effect. 35 Exercise Prescription Fitness Effect Analysis 351 Overall Evaluation of Fitness Effects Analysis Before and after exercise prescription exercise, the HR values ​​decreased after exercise, and SV, SI, CO, CI, and VPE increased. There are significant differences in the indicators. The slowing of the pulse during exercise that causes quietness is a good response to bradycardia, while the increase in stroke volume (SV) and its index (SI), which are displayed synchronously, shows an increase in myocardial contractility, suggesting three types of exercise prescriptions It has a significant effect on enhancing myocardial contractility. A large number of studies have shown that the development of cardiac pump function should be based on aerobic exercise, that is exercise intensity control in the heart rate of 120-150 beats / min. In the course of this experiment, pulse intensity was used to monitor exercise intensity, and the average heart rate of the basic part of the three exercise prescriptions was: 14875 beats/min for the strength group and 14076 beats/min for the women; 137.82 beats/min for the endurance group; 14087 for the women / Points; full group men 13046 beats / min, women 1368 beats / min. It shows that the intensity of exercise prescription is appropriate, and the enhancement of heart pump function after exercise prescription is completely reasonable. 16. Analysis of the status of the heart pump function in male and female control group shows that a number of indexes of female college students are the second test ratio. The first time, male college students were completely the opposite. This phenomenon is similar to the results of Huang Yushan et al's study, 71 which suggests that male students have higher enthusiasm for participating in physical training and competition outside class, so the decline in physiological function and physical fitness is not obvious. Female students consciously often have poor enthusiasm for extracurricular physical exercise and are more likely to experience a decline in physical function. Therefore, it is particularly important for female college students to strengthen their fitness awareness. 352 Comparison of the fitness effects of the three types of fitness exercise prescriptions The fitness effects of each group are compared and the respective fitness characteristics can be seen. The implementation of endurance group fitness prescriptions, HR values ​​of male and female college students have significantly decreased, while SV, SI, VPE has a very significant increase. Although the exercise of the other two prescriptions also had a good effect, it was not as pronounced as the endurance group. It is suggested that the endurance group fitness prescription has the best effect on enhancing the heart pump function. After comprehensive exercise, in addition to improving myocardial contractility, at the same time, the MSP, MDP, and MAP of female college students were significantly decreased. This is a good adaptation of vascular function to exercise, suggesting that the comprehensive group has a more comprehensive fitness effect. Summary and recommendations 41 The research results show that the implementation of strength, endurance, and comprehensive exercise of the three kinds of fitness exercise prescriptions, exercise intensity is appropriate, both male and female college students have good heart pump function improvement, can significantly enhance the myocardial contractility. The comparison of the fitness effects of the three types of exercise prescriptions suggests that the endurance exercise has the best effect in developing the heart pump function, and the comprehensive group exercise can also significantly improve the vascular function, and its fitness effect is more comprehensive. 43 The results of two cardiac pump function tests in the male and female control groups were compared, suggesting that female college students have poor enthusiasm for participating in extracurricular physical exercises, and are more likely to experience a decline in physical function. They should strengthen their awareness of fitness and participate in physical exercise. 4 Studies have shown that using appropriate fitness exercise prescriptions for extracurricular exercise, fitness conditions are simple, fitness methods are scientific, and fitness effects are obvious. It is recommended to promote it vigorously to promote the scientific process of undergraduate and even national fitness activities.
