| Research purposes: Body composition index is an important judgment basis for evaluating the effect of bodybuilding exercise.In recent years,with the success of our national fitness program and the popularization of sports and nutrition knowledge,the utilization and demand rate of sports nutrients are much higher than before.Domestic and foreign research and practice show that the use of sports nutrient supplements in bodybuilding exercises has a more obvious effect on the improvement of human body composition,so this study takes the use of sports nutrient supplements as a variable to carry out experiments.To explore the effect of sports nutrition supplement on body composition in bodybuilding exercise,and to increase the popularity and recognition of sports nutrition supplement,so as to provide some reference and guidance for bodybuilding enthusiasts to use sports nutrition supplement.In this study,whey protein powder,glutamine powder,branched-chain amino acid powder and liquid L-carnitine were used as four supplements.The research methods include experiment,literature,mathematical statistics and comparative analysis.Methods: Meida International Fitness Club in Yaodu District of Linfen City mobilized members to participate in the experiment actively.At last,32 participants,16 males and 16 females,were confirmed to participate in the experiment.The subjects were randomly divided into male and female experimental groups and control groups.As I am also a member of Meida Fitness Club,I am familiar with the club,which is conducive to the development and conduct of the experiment.Summer is the peak period of summer vacation for students and bodybuilding enthusiasts.During the summer vacation,people have more leisure time,and communicate with the fans of the fitness club members.This explains the purpose of the experiment and mobilizes them.They took part in the experiment.Test method of body composition data: bioelectrical impedance method.SPSS and Excel are the statistical tools used in the statistical analysis in this paper.At first,independent sample t-test is used to analyze the measured data.Then,t-test is carried out on the data of pre-testand post-test in different groups.The test results P < 0.05 show that there are significant differences in body composition before and after exercise,and P < 0.01 indicates that there are significant differences in statistics.Results: After the end of the experimental period,the body weight(P < 0.05),body fat rate(P < 0.05),visceral fat(P < 0.05)of female bodybuilding enthusiasts in the experimental group decreased and decreased,and the basal metabolic rate(P < 0.05)increased and increased.The body weight except fat increased.The improvement effect of the experimental group using sports nutrition supplement was better than that without sports camp.The control group was treated with tonic.At the end of the 8-week experiment,the results of male data were satisfactory.The body composition data of the experimental group and the control group were improved to a certain extent.The body weight,body fat rate and BMI of the experimental group using sports nutrition supplement decreased(P<0.05),and there was a continuous downward trend.The muscle mass and basic metabolism were improved.(P < 0.05),and the improvement of body composition in the experimental group was better than that in the control group.It shows some advantages of using sports nutrition supplement in bodybuilding.During the whole experiment,there were no adverse reactions in the experimental group.Research conclusions:(1)The use of sports nutrition supplements in bodybuilding exercise can promote the improvement of body composition.The indexes of body composition such as body fat rate,body weight and body quality of bodybuilders who use sports nutrition supplements and their sports effects have been improved obviously,which fully reflects the significance of sports nutrition supplements in promoting bodybuilding.(2)In this study,bodybuilding enthusiasts who did not use sports nutrition supplements also improved their body composition in the process of exercise,but the effect was not ideal.Compared with the bodybuilding enthusiasts who use sports nutrition supplements,the improvement effect is more general.(3)The body composition of bodybuilding enthusiasts will be improved no matter whether they use sports nutrition supplements or not in the process of bodybuilding,but the difference is that the benefits of the two in the same period are different;the bodybuilding enthusiasts who use sports nutrition supplements get relatively greater improvement.For the improvement of body composition,it can not be achieved overnight in a short time.It needs to maintain good habits,exercise and nutrition for a long time in order to achieve a better individual effect. |
