Szukana fraza: [Abstrakt = "Introduction. Numerous studies have focused on the association between I\/D ACE and physical fitness\; however, this association in professional hockey players has never been recognized. Aim of the Study. The study examined the distribution of Alu insertion \(I\)\/deletion \(D\) angiotensin converting enzyme \(ACE\) genotypes in elite male professional field hockey players. Material and Methods. The effect of Alu insertion \(I\)\/deletion \(D\) angiotensin converting enzyme \(ACE\) genotypes on motor skills and maximal oxygen uptake \(VO2max\) in 47 elite male field hockey players was studied. Genotyping for ACE I\/D was performed using a polymerase chain reaction on DNA from leucocytes. The studied motor skills such as speed – 20 m run, power – vertical jump, recovery – step\-test, speed endurance \(15 x 20 m\) shuttle run, were established using functional tests. The VO2max was measured during progressive exercise test till exhaustion. Results. The authors do not confirm some literature data that D allele favours endurance ability. We did not detect significant genotype effects of ACE on the analyzed traits\; however a tendency for decreased performance of individuals with the DD genotype was noted for vertical jump, power peak and power. Conclusions. Analysis of the genetic profile of ACE I\/D may provide supplemetary information on a player’s predispositions to exercise with specific energy requirements."]
