بررسی تاثیر شش هفته تمرینات قدرتی و پلایومتریک بر تعادل پویای دانشجویان مرد ورزشکار

Abstractintroduction: the purpose of this study was to consider the effects of strength and plyometric training on dynamic balance of male athlete students.materials and methods: 30 elderly males with average and standard deviation age of 23.18 ± 4.95yr, weight 72.17 ± 3.09kg and length 173.58 ± 3.63cm without any precedence of lower extremity, voluntarily participated in this study. they divided into two groups as follow: group 1: strength- plyometric (n = 15) exercise 2: control group (n = 15). one day before from executing of strength and plyometric exercises, dynamic balance assessed with using the star excursion balance test (sebt). within 6 week that exercises group executing exercise programs, control group asked to continue their daily common activities. one day after from completing of exercises, dynamic balance of subjects assessed with using the sebt test. descriptive statistic was used to determine the mean of subjects' characteristics and reaching distance in eight directions of sebt. paired sample t-test was used to compare the mean differences for pre- and post-test data. also t-test for independent groups was used to compare the data for two groups. p values < 0.05 were considered significant.results: significant differences were seen between pre and post reaching distance using sebt after the applying strength-plyometric training program for practice group in all directions of sebt. the results not showed any difference between pre and post reaching distance in sebt for control group. also significant differences were seen between practice and control groups after the applying strength-plyometric training program in all directions of sebt.conclusion: due to results, using concurrent exercises (strength-plyometric training) in training programs are recommended to decrease likelihood improve the athletes' dynamic balance.keywords: strength-plyometric training, dynamic balance.
