Background: Creatine and Creatinine plays a role in muscle function. Urinary creatine and urinary creatinine concentration was measured in order to see significance in monitoring athlete and athlete’s performance. Objective: Evaluate association of dietary protein intake, Lean Body Mass (LBM) percentage, Body Mass Index (BMI) and physical activity on urinary creatine, urinary creatinine concentration in different team sports [cricket players (C), basketball players (B) and football players (F)]. Methodology: A total of 62 players from different team sports - C (n-20), B (n-17) and F (n-25) age of 18-30 years participated. Post training urine samples was analyzed. Using Jaffe's reaction, urinary creatinine was obtained and Urinary creatine is obtained by difference in the creatinine present before and after heating with acid solution. 24 hour dietary recall was taken to find athletes protein intake. LBM were taken using Body Impedence Analysis (BIA machine). Data were analysed using SPSS (Statistical Package for Social Sciences Version 16.0). Findings: Pearson bivariate correlation (2-tailed) was used to find the relationship between BMI, LBM, total dietary protein intake per day, dietary protein, duration of practice with urine creatinine and creatine level. Positive correlation between urinary creatine and total dietary protein intake per day, dietary protein according to body weight per day was found (p<0.001), (p<0.005) respectively. Negative correlation between urinary creatinine and dietary protein according to body weight per day and duration of practice per day was found (p<0.001), (p<0.005) respectively. Urinary creatine mean (SD) values- C group 78.63 ± 27.17, B group 102.65 ± 38 and F group 169.60±41.58. Urinary creatinine mean (SD) values- C group 46.60 ± 37.23,B group 84.88 ± 48.27 and F group 70.40±44.083. Conclusion & Significance: Significant increase was seen in urinary creatine excretion with respect to dietary protein per day, dietary protein according to body weight per day. Urinary creatine excretion is more in football players followed by basketball players. Significant decline was seen in urinary creatinine excretion with respect to increase dietary protein according to body weight per day and increase duration of practice. Urinary Creatine excretion is more in basketball players followed by football players Urinary creatine and urinary creatinine excretion depends on sports-type, duration of sports and protein consumption.
