| Objective:For the improvement of the physical fitness of drug addicts in compulsory isolation,collective sports activities are used as a means of exercise intervention.Through the comparison before and after the experiment,the physical indicators of drug addicts before and after participating in collective sports activities are used as data to confirm that collective sports activities can improve and even enhance the physical fitness of drug addicts in compulsory isolation.Meanwhile,the research will compare the collective sports activities with the traditional rehabilitation method Baduanjin to observe the improvement effect of the two interventions on physical fitness.Research objects and methods:From December 2021,the pre-test has ended,and after 8 weeks of exercise intervention,the post-test is conducted.A total of 75 drug addicts are selected from the compulsory isolation detoxification center in Weinan City,Shaanxi Province as exercise intervention objects.According to the average physical quality,they are divided into collective game intervention group 1,collective game intervention group 2,basketball intervention group 1,basketball intervention group 2,and control group,with 15 people in each group.The basketball intervention group 1 and the collective game intervention group 1 train 3 times a week on Thursday and weekend,the basketball intervention group 2 and the collective game intervention group 2 train 2 times a week on Thursday and Sunday,60 minutes each time.The first 1-2 weeks are adaptation weeks,and the intensity heart rate is 100-120beats/min,which belong to the sports learning week.The 3-6 weeks are formal interventions,and the intensity heart rate is 120-140 beats/min.The 7-8 weeks are intensive weeks,and the intensity heart rate is 130-150 beats/min.The control group participate in the routine detoxification and correction activities of Weinan detoxification center(Baduanjin).The physical changes of the five groups of subjects before and after the experiment are recorded and analyzed.Results:1.Body shapeAfter 8 weeks of experimental intervention,there is no significant difference in the improvement of height and weight indexes(p>0.05).2.Cardiopulmonary function(1)Intra-group comparison before and after the experimentAfter 8 weeks of experimental intervention,the cardiopulmonary function of the drug addicts has been improved.In the intra-group comparison before and after the experiment,there is a significant difference in the diastolic blood pressure index between the subjects in the basketball intervention group 1 and the subjects in the game intervention group 2(p<0.05);there is a significant difference in the quiet heart rate index in the control group(p<0.01).(2)Comparison between groups after the experimentAfter 8 weeks of exercise intervention,there is a significant difference in the quiet heart rate index(p<0.01),and the control group is better than the basketball intervention group 1 and the game intervention group 2.3.Physical quality(1)Intra-group comparison before and after the experimentAfter 8 weeks of exercise intervention,the physical fitness of drug addicts in compulsory isolation has been significantly improved.The subjects in the basketball intervention group 1 has extremely significant differences in the indexes of sitting forward flexion,closed eyes and one foot standing,choice reaction time,vertical jump,30-meter run and 800-meter run(p<0.01);the subjects in the basketball intervention group 2 have a significant difference in the 800-meter running index(p<0.01).There are significant differences in 30-meter running,choice reaction time and vertical jump index between the subjects in the game intervention group 1(p<0.01).There are significant differences in the indexes of sit-and-reach,30-meter running,push-ups and 800-meter running in the game intervention group 2(p<0.01).(2)Comparison between groups after the experimentAfter 8 weeks of exercise intervention,there is a significant difference between the 30-meter run and the 800-meter run(p<0.01),and the experimental group is better than the control group;there is a significant difference in the push-up index(p<0.01),and the game intervention group is better than the control group.There is no significant difference in the improvement of physical fitness between the experimental group with two interventions per week and three interventions per week.There is a significant difference between the basketball intervention group and the 30-meter run and the vertical jump index(p<0.01),and there is a significant difference in the choice reaction time index(p<0.05).There is only significant difference in the choice reaction time index between the collective game intervention groups(p<0.05).There is no significant difference in each item index between the basketball intervention group and the collective game intervention group(p>0.05).There is a significant difference between the basketball intervention group two and the collective game intervention group two in the 30-meter run index(p<0.05).Research conclusions:1.Eight weeks of basketball and collective game intervention have significantly improved the flexibility,speed,strength and endurance of the drug addicts,among which basketball intervention has a special effect on the balance ability of the drug addicts.2.The intervention group of basketball and collective games is better than the control group of Baduanjin in moving speed and endurance quality,and the intervention group of collective games is better than the control group of Baduanjin in strength and endurance,indicating that basketball and collective games are better than Baduanjin in improving physical fitness.3.3.After 8 weeks of exercise intervention,training twice a week and training three times a week have little effect on the improvement of physical fitness of drug addicts in compulsory isolation.Basketball and collective games have similar effects on the improvement of subjects ’ physique during 8 weeks of exercise intervention. |
