Prolonged exercise is known to increase steady-state serum high-density lipoprotein cholesterol (HDL-cholesterol) and apolipoprotein AI(apo AI) concentrations. We investigated the effect of adaptation to endurance exercise on the association of the genetic polymorphism in the apo AI gene with these biochemical parameters. 108 male subjects were randomly selected from a group of elite athletes, and 65 male samples used as sedentary control group from Korean general population. The genetic polymorphism in the apo AI gene locus was detected by polymerase chain reaction(PCR) and DNA digestion with Msp I restriction endonuclease. The genotype frequency for the Msp I RFLP was significantly different between the elite athletes and sedentary controls(P<0.05). There were, however, no significant associations between the Msp I RFLP of the apo AI gene and the biochemical parameters in elite athletic group. Therefore, our findings indicate that the Msp I RFLP of the apo AI gene was not associated with the serum apo AI and HDL-cholesterol concentrations in Korean male elite athletes.

n view of the role of haptoglobin as a candidate for physical performance, we investigated the protein polymorphism of the haptoglobin in elite Korean male athletes. The serum sample was collected from 120 Korean male eliteathletes. The haptoglobin phenotypes were determined by polyacrylamide gel electrophoresis, followed by peroxidase staining. (omitted)

이 연구는 한국인에서 적용할 수 있는 근력관련 유전적 소인을 ACE 유전자와 ACTN3 유전자를 단일유전자 수준과 다중유전자 수준에서 관계성을 규명하는데 목적이 있다. 연구의 목적을 위해 근력운동종목의 엘리트선수 158명, 국가대표선수 106명, 대조군 676명을 동원하여 ACE ID 다형성과 ACTN3 R577X 다형성 분포를 분석했다. 연구결과, ACE 다형성에서 II 유전형 및 I 대립형질은 유의하게 높은 분포를 가졌고, 반면 DD 유전형 및 I 대립형 질은 유의하게 낮은 분포를 가졌다(Top-Class vs. Control: 41.4% vs. 32.1 for II genotype, 67.1% vs. 57.7% for I allele, p<0.05). ACTN3 다형성에서 RR 유전형 및 R 대립형질은 유의하게 높았고 XX 유전형 및 R 대립형질은 유의하게 낮았다(Top-Class vs. Control: 42.3% vs. 29.0 for RR genotype, 65.3% vs. 54.8% for R allele, p<0.05). 다중유전자 수준에서 근력은 ACE 다형성과 ACTN3 다형성이 조합된 우성조합유전형(II/ID+RR/RX)이 최우수 경기력에서 유의하게 높은 분포를 가졌다(Top-Class vs. Control: 82.9% vs. 66.7% for II/ID+RR/RX, p<0.05). 또한 최우수 경기력을 가진 국가대표는 엘리트와 대조군 보다 유의하게 높은 TGS를 가졌다($66{\pm}0.9$ vs. $58{\pm}1.9$ vs. $56{\pm}2.3$, p<0.05). 이를 근거로 우성조합유전형이 최우수 근력 경기력을 가질 가능성에 대한 승산비는 2.43배(CI:1.45-4.09, p<0.001)였다. 따라서 ACE 다형성과 ACTN3 다형성은 한국인에서 근력과 관계된 유전형으로 확인되었으며, 두 유전자는 상호 조합된 다중유전형에서 근력 경기력에 영향을 줄 것으로 사료된다. 또한 ACE 다형성과 ACTN3 다형성을 조합한 다중유전자는 근력 경기력을 예측할 수 있은 유전적 요인으로 사료되었다.

Serum lipid and lipoprotein levels are influenced by genetic factors, and exorcise increases the concentrations of cardio-protective parameters such as high-density lipoprotein cholesterol (HDL-cholesterol) and apolipoproteinAI (apoAI) in human serum. In the present study, we tested the effect of adaptation to endurance exercise on the association of a genetic polymorphism (Pst 1 RFLP) in the apoAI gene with these biochemical parameters. The genotype and allele frequencies for the Pst 1 RFLP were not significantly different between the elite athletes and sedentary controls (P>0.05). There were also no significant associations between the Pst 1 RFLP of the apoAI gene and the biochemical parameters in elite athletic group. Thus, our results suggest that the Pst 1 RFLP of the apoAI gene was not significantly associated with the serum apoAI and HDL-cholesterol concentrations as well as athletic performance in Koreans.

In view of the importance of muscle-specific creatine kinase (CKMM) gene as a genetic factor for athletic performance, we investigate the relationship between elite athletic performance and two restriction fragment length polymorphisms (Ncol and Taql RFLPs) in the CKMM gene. Genomic DNA was extracted from white blood cells of 98 unrelated male Korean elite athletes and 04 sedentary controls, respectively. Two genetic polymorphisms in the CKMM gene were detected by the polymerase chain reaction and the digestion with restriction endonucleases, Ncol and Taql, respectively. There were no significant associations between two genetic polymorphisms in the CKMM gene and elite athletic performance or clinical parameters in our subjects. Therefore, these findings suggest that two genetic polymorphisms in the CKMM gene may not be useful as genetic markers to predict the athletic performance in male Koreans.

The purpose of this study was to investigate the relationship between Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene and complex phenotypes such as blood pressure, body compositions and bone parameters in young men about 20 years, and to collect the fundamental data in designing the exercise program. Eighty healthy young men including 41 controls and 39 athletes were recruited, Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene was genotyped by PCR-RFLP method. By association study, there were no significance in genotype and allele frequencies of Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene between controls and athletes, respectively (p>0.05). When the relationship between physiological parameters and Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene was tested, this polymorphism was significantly associated with 3th lumber and left femoral neck Z-score values in controls (p<0.05), but these associations were not detected in athletic groups (p>0.05). It is likely that Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene is a genetic marker for the bone mineral density index in young men, but environmental factors such as exercise modify the significant effect of this polymorphism. Thus, our results suggest that Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene may be applicable as a predictive marker for osteoporosis in Korean young men, and regular exercise may prevent the disadventageous effect of this polymorphism for bone mineral density in male athletic group.
