Abstract
The aim of this study was to examine the concurrent consumption of creatine and resistance training on flexion strength of biceps brachii in female physical education students in their last semester. For this purpose, 30 students were randomly selected and divided into three groups: the experimental group 1 (age: 19.8 ± 1.4 yr, weight: 53.9 ± 4.4 kg, height: 162 ± 4.4 cm), experimental group 2 (age: 19.6 ± 1.3 yr, weight: 51.2 ± 7.5 kg, height: 162.8 ± 5.2 cm) and control group (age: 19.8 ± 1.0 yr, weight: 59 ± 3.9 kg, height: 162 ± 4.9 cm). All three groups performed the pretest and posttest after 6 weeks to measure the flexion strength of biceps brachii using a dynamometer. Experimental groups 1 and 2 participated in the 6-week McQueen resistance training program while experimental group 1 consumed creatine supplement and experimental group 2 consumed placebo. The control group did not participate in any training intervention and did not consume any supplements and placebo. To analyze the data within a group, dependent t test and among the groups, one-way ANOVA was used with SPSS ver.18. The results showed that in the experimental group 1, the flexion strength of biceps brachii increased significantly after 6 weeks of concurrent consumption of creatine supplement and resistance training (P=0.004). In the experimental group 2 (placebo), no significant differences were observed in the amount of the strength of this muscle (P=0.242). In the control group, strength significantly decreased (P=0.001). In general, it can be concluded that the concurrent consumption of creatine supplement and resistance training can be beneficial in order to increase strength, especially for better performance in sport events.
