Serum creatinine in normal sudanese athlets and soldiers

Abstract

Plasma levels of creatinine are related to the relative muscles mass, the rate of creatine turnover and the renal function. It has been accepted for years that the plasma level of creatinine is relatively un affected by the diet. However, some reports have indicated that the protein content of the diet may be indeed affect the plasma level of creatinine if it affects the individuals muscles mass. This a primary study that aims to detect rough estimation of serum creatinine in normal Sudanese athletes and soldiers. In addition to detect weather creatinine level is associated by gender, age, daily working hours or occupation of study population. Hundred (49 soldiers: 51 athletes) normal individuals from Khartoum state invited to take a role in this study (75 male: 25 female) their age was between 14-44 years. At P ≤ 0.05 this study showed no significant differences (P 0.772) in creatinine concentration with mean ± SD (1.07 ± 0.11, 1.12 ± 0.17 mg/dl) for soldiers and athletes respectively. There was no signifigant difference in creatinine concentration either between both sexes male: female (1.1 ± 0.16: 1.1 ± 0.12), or between different occupations soldiers: athletes (1.07 ± 0.11: 1.12 ± 0.17). But there was significant difference (Chi 0.027) in creatinine concentration (0.5, 1.0, 1.5) for (14-24, 25-34, 35-44) age groups respectively. Serum creatinine was not associated with daily working hours (ANOVA 0.18) with creatinine values (1.16, 1.01, 1.12, 1.13, 0.8) for weekly working hours (≤ 20, 21- 40, 41- 60, 61 – 80, 81-100). Serum creatinine is not much different depending on the gender, individual occupation or daily working hours, weather they were soldiers or athletes, but it is influenced by age progress. Sudanese soldiers and Athletes creatinine level fell within the normal international range. Research with large data collection is recommended for establishment and localization normal range of biochemical parameters for sport medicine in Sudan.
