In order to analyze the influence of exercise on cardiopulmonary function under strong pollution. This paper selects 60 track and field athletes in a certain city, and divides them into three groups randomly, namely the severely polluted exercise group, the severely polluted control group, and the low pollution control group. Each group has 20 people. The severely polluted exercise group is in a highly polluted environment. Under the Bruce plan, the severely polluted control group did not exercise, but was in a strongly polluted environment together with the severely polluted exercise group. The low-polluted control group did not exercise but was in a lowpolluting environment. The results showed that the resting heart rate, systolic blood pressure, diastolic blood pressure, pulse pressure, and heart work index of the severely polluted exercise group were higher than those of the severely polluted control group and the low-pollution control group, and the resting heart rate, pulse pressure, heart work index of the severely polluted exercise group shows significant difference (P<0.05) compared with those of the low-pollution control group. The systolic blood pressure was significantly different from that of the strongly contaminated control group (P<0.05). The ESD, EDD, ESV, EDV, MSER and MVCF of the severely polluted exercise group were higher than those of the severely polluted control group and the low-polluted control group. Among them, EDV and MVCF from severely polluted exercise group was significantly different from the value from the low-polluted control group (P<0.05). Compared with the severely polluted control group, EDV and MSER have significant differences (P<0.05). Compared with the severely polluted control group, MVCF has a very significant difference (P<0.01). After the experiment in the severely polluted exercise group, FVC, FEV1, FEF 25%-75% and FEF increased significantly compared with the values before the experiment, and there was a very significant difference (P<0.01). The MVV was significantly lower than that after the experiment, and there was a very significant difference (P<0.01). There was no significant difference between the severely polluted control group and the low pollution control group before and after the experiment. Under heavy pollution exercise, exercise has a very positive effect on improving and improving cardiopulmonary function. [ABSTRACT FROM AUTHOR] |
