The Relationship between Digit Ratio and Genotypes of Angiotensin Converting Enzyme with Strength Muscle on National Company South Oil Professional Weight Lifter Men

The aim of this study investigated relationship between digit ratio (2D: 4D) and genotype of angiotensin converter enzyme (ACE) with muscle strength of elite weight lifters. In order to، at first session، body composition، snatch، clean and jerk and total in 18 elite weight lifter volunteers (Age: 23. 2 ± 2. 8 years، Height: 176. 1 ± 9. 3 cm، Weight: 97. 9 ± 28. 3 kg) in super league in Khuzestan and national oil company were measured. At second session، 5mm blood sample was taken in fasting condition to count genotypes of ACE using PCR devices. Simple correlation showed that there is no significant relationship between digit ratio (p=0. 3) and genotypes ID (P=0. 4) and DD (P=0. 39) ACE with muscle strength. Using partial correlation analysis and eliminating effect of body weight on variables showed significant relationship between ID (P=0. 01) and DD (P=0. 01) ACE with muscle strength. Regression showed that a model can be presented to estimate muscle strength using 2D: 4D، lean body mass and ACE genotype. According to results، it can be said that 2D: 4D may be used as a factor in finding talents programs in weigh-lifting federation. Concerning effects and characteristics of ACE genotypes on hypertension and cardio-vascular homeostasis and considering its correlation with musculare strength، wide spread research is needed to find advantages of improving muscular strength on health.
