Abstract:Introduction: Genetic factors appear to explain why some athletes perform better in competition and training than their peers. Objective: To determine the occurrence of R577X polymorphism of the ACTN3 gene in mountain runners. Methods: The sample consisted of 19 female mountain runners with a mean age of 41.2 ± 6.1 years. Genotyping of R577X polymorphism of the ACTN3 gene was performed by the polymerase chain reaction (PCR) method with DNA extracted from saliva. The genotypic and allelic frequencies of the a… Show more

Introduction Physical training is a well-known training method in competitive sports. However, in the majority of the physical training classes, the focus is still on the traditional exercises of physical conditioning as strength, speed, resistance, etc., directed for young athletes that are in the growth and development phase, without a literary base to assure actual effectiveness in the load increases for the athletic performance facing the risks in the athletes’ physical proprioception. Objective Explores the effect of functional training on the physical sensibility of sports athletes. Methods The data collection method is used in the daily training of six notable athletes in a district sports school: judo, martial arts, wrestling, tennis team, swimming team, and table tennis team, adding the functional training protocol in body movement. Results The average performance of the groups before and after the experiment was collected and confronted, the difference test was performed, and the test result found P>0.05. The athletes in the experimental group not only improved the footwork speed and physical coordination, the movement speed of the footwork and the speed of the connection between movements increased significantly in the sixth week, reflecting more excellent stability and motor coordination in the movements. Proprioception is one of the essential sports qualities of the human body; it is directly related to physical qualities such as speed and strength and is also closely related to the different neural pathways. Conclusion Functional training can improve athletes’ physical flexibility and motor coordination; it can also stimulate body proprioceptors, increase athletes’ confidence, and make training more efficient and effective. Evidence level II; Therapeutic Studies - Investigating the results.

IntroductionThe phenotypic consequences of the p.Arg577Ter variant in the α‐actinin‐3 (ACTN3) gene are suggestive of a trade‐off between performance traits for speed and endurance sports. Although there is a consistent association of the c.1729C allele (aka R allele) with strength/power traits, there is still a debate on whether the null allele (c.1729T allele; aka X allele) influences endurance performance. The present study aimed to test the association of the ACTN3 p.Arg577Ter variant with long‐distance endurance athlete status, using previously published data with the Brazilian population.MethodsGenotypic data from 203 long‐distance athletes and 1724 controls were analysed in a case–control approach.ResultsThe frequency of the X allele was significantly higher in long‐distance athletes than in the control group (51.5% vs. 41.4%; p = 0.000095). The R/X and X/X genotypes were overrepresented in the athlete group. Individuals with the R/X genotype instead of the R/R genotype had a 1.6 increase in the odds of being a long‐distance athlete (p = 0.012), whereas individuals with the X/X genotype instead of the R/R genotype had a 2.2 increase in the odds of being a long‐distance athlete (p = 0.00017).ConclusionThe X allele, mainly the X/X genotype, was associated with long‐distance athlete status in Brazilians.
