(The Effect of Creatine Supplementation and Resistance Training on Strength, bodyTestosterone, and Lactate DehydrgenaseComposition, Resting Metabolic Rat Amongest Bodybuilders)

The study aimed to identify the effect of taking creatine supplementation and resistance training on strength and body composition and metabolism during rest and testosterone and Lactate Dehydrgenase with players bodybuilders athletic. This study was conducted on a sample of (30) players from different clubs and centers for sports bodybuilding in the northern region West Bank (Nablus), where the average (age, height, body mass, and body mass index (BMI) have respectively (20.8 years, 176.9 cm, 71.2 kg, 22.7 kg / m 2), was chosen purposely, where they were split The study sample into two groups (experimental), by (15) player of the experimental group dealing with substance creatine in addition to resistance training, and (15) player of the experimental group that lead resistance training only, where the first experimental group perform resistance training with taking creatine, Group experimental second lead resistance training without taking creatine, but the variables of the study were certain hormones (testosterone) and enzymes (Lactate Dehydrgenase (LDH)), and strength, and body composition, metabolism during rest, in order to process the data, the researcher used the packets statistical Social Sciences program (SPSS), and through the t-test for couples (Paired-t-test) to answer the first question and the second, in addition to the percentage of change ratios, and t-test for two independent groups (Independent-t-test) to determine the difference in the dimensional measurement in variables under study between members of the two groups. Results of the first question showed that there were no statistically significant differences at the level of significance (α = 0.05) between the two measurements pre and post in the variables: BMI, metabolism during rest, and mass-free grease the body, and the body mass of water, and testosterone with a group of individuals Creatine supplementation and resistance training, while significant differences between the two measurements pre and post and in favor of the dimensional measurement variables (strength, body mass, and the proportion of grease, and mass greasand Lactate Dehydrgenase, where the percentage of change in these variables, respectively: (12.15%, 1.22%, 15.60%, 14.57%, 12.62%), and the increase occurred in the averages of these measurements and in favor of telemetric. The results of the second question that there were no statistically significant differences at the level of significance (α = 0.05) between the two measurements pre and post in the variables: metabolism during rest, and mass-free grease the body, and the body mass of water, and and Lactate Dehydrgenas, and testosterone with individuals training group resistance, while the differences were statistically significant between the two measurements pre and post and in favor of telemetric in variables (strength, body mass, body mass index, and the percentage of grease, and mass grease, where the percentage of change in these variables, respectively: (7.86%, 1.54%, 1.79%, 11.28%, 12.98%), and the increase occurred in the averages of these measurements and in favor of telemetric. The results of the third question that there were no statistically significant differences at the level of significance (α = 0.05) in the variables: BMI, body mass index, and metabolism during rest, the block body fat, and block-free grease the body, and the body mass of water, and and Lactate Dehydrgenas and testosterone in the dimensional measurement between members of the creatine group as a dietary supplement and resistance training together and members of resistance training inindividually were statistically significant differences in the dimensional measurement variables: power, and the percentage of grease, and Lactate Dehydrgenasbetween members of the creatine group as a dietary supplement and resistance training together and personnel training resistance individually and for the group as a dietary supplement creatine and resistance training together. The researcher recommends circulate the results of the current study on all the Palestinian universities, centers and clubs bodybuilding and fitness, sports federations, to take advantage of their results by working in this area whether they are academics or trainers.
