Abstract

Introduction
previous research has shown that ACTN3 rs1815739 and COL5A1 rs12722 polymorphisms may affect power performance. This research aimed to investigate the relationship between ACTN3 and COL5A1 polymorphisms with the baseline level of power performance and its effect on adaptation to plyometric training.
Methods
The research subjects were 38 boys with an average age of 10.3 ± 0.53. Vertical jump (CMJ) and horizontal jump (SBJ) tests were used to evaluate lower body muscle power. The plyometric training protocol was for 6 weeks. DNA was extracted from saliva and genotype was determined by PCR-RFLP method. Based on genetic analysis, people were divided into the following groups in the ACTN3 polymorphism: RX (n=20), RR (n=13), and XX (n=5), and in the COL5A1 polymorphism: CT (n=19), CC (n =8) and TT (n=11). ANCOVA test was used for statistical analysis.
Results
The results showed that plyometric training caused a significant increase in CMJ and SBJ tests (p<0.05). However, no significant difference was observed when the average basic performance and adaptation to plyometric training were compared according to ACTN3 and COL5A1 genotypes (p>0.05).
Conclusion
plyometric training effectively increases power in children, but these differences are probably not affected by ACTN3 and COL5A1 genotypes.
