The effect of self-regulatory strategies on serum GDNF levels, cognitive function, and acquisition of Three-step Handball shooting skill
Physical and behavioral activity that increases GDNF in the brain can maintain the ductility of the brain and facilitate learning. Also, decision-making processes in the learning environment, will help to learn sport skills. The present study aimed to investigate the effect of self-regulatory strategies on serum GDNF levels, cognitive function, and acquisition of three-step handball shooting skills.
42 inactive boys 18 to 24 years were randomly selected as the sample. Statistical samples were divided into three groups: self-regulation, control with practice, and control without practice. Subjects in 15 sessions to shoot handball activities according to the Zien handball test. 48 hours before and after pre-test and post-test, blood samples were taken, and cognitive function test was performed as Stroop test. Blood factor GDNF was measured by ELISA. Statistical analysis was performed by SPSS 22 at P≤ 0.05 level.
metacognitive strategies did not have a significant effect on serum GDNF levels (P=0.67) and also on cognitive function (P=0.07) but on the acquisition of three-step handball shooting skills Had a significant effect (P˂0.01), also according to the results of one-way analysis of variance to compare changes in three groups in the three-step handball shooting skill index after training protocol (P˂0.01) There was a significant difference between the groups that according to the results of Scheffe post hoc test, there was a significant difference between the self-regulatory group with control without practice and control with practice (P˂0.01). But the mean difference was not significant between the other groups.
These findings show that the use of self-regulatory strategies is effective in teaching handball three-step shooting skills. Recommended that coaches use metacognitive strategies during teaching sessions, and athletes, particularly beginners, should use metacognitive strategies to learn more and better skills and improve their performance.
