초록

This study suggests the standard for selecting the best players by examining superior male speed-skaters about the association between ACTN-3 gene polymorphism for each events and the aerobic·anaerobic ability. For this, we selected male—26 short-distance/25 long-distance registered in Korea Skating Union. Gene analysis for each inspection items used Genomic DNC in epithelium cell of the mouth, and aerobic ability test (GXT) and anaerobic ability test(Wingate test) were conducted. First, frequency distribution of ACTN-3 gene polymorphism of superior speed-skaters was presented: 4 of XX type (15.4%), 10 of RR type (38.4%) and 12 of RX type (46.2%) among male short-distance skaters group; 5 of XX type (20%), 11 of RR type (44%) and 9 of RX type (36%) among male long-distance skaters. Second, the difference of aerobic ability according to ACTN-3 polymorphism was post-examined for each groups and for each gene types; in VO2max items of male skaters, statistically significant difference existed between XX and RX types (p<.05). In HRmax of aerobic ability, there was no statistically significant difference between groups and between gene types, but XX > RX > RR meaning XX type was well developed. Third, the difference of anaerobic ability according to ACTN-3 polymorphism was post-examined for each groups and for each gene types; in peak power items of male skaters, there was statically significant difference between XX and RR, between XX and RX (p<.05, p<.01), and there was statistically significant difference between XX and RR in men's peak power(kg); in total work items, statistically significant difference existed in between XX and RX (p<.01). It is difficult to analyse XX type which reflects the lackage of protein composing Z-line of myofilament structure in relation with aerobic ability like VO2max(maximum oxygen intake) and HRmax(maximum heart rate), and moreover the examination about the significance between gene types of for their physiological characteristics, should be suggested in some studies that can be analysed in central dogma theory.
