Abstract

Introduction:Urea is produced in thebody as part of the urea cycle from the oxidation of amino acids, indicating the catabolism of the proteins for energy production. Moreover, another marker involved in muscle breakdown is creatinine, which expresses the metabolism of creatine in the muscle (1).The effect of endurance training on blood urea and creatinine levels is not well defined in elder subjects. Therefore,the aim of the present study was to investigate the effect of low- and high-intensity endurance trainings on urea and creatinine levels in older women. Methodology:Twenty five sedentary women (age 59.52±2.16 year-old) were recruited and randomly divided into control, low- and high-intensity training groups. Eightweeks of low- and high-intensity exercise training wereconducted on the stationary cycle ergometer at intensity corresponding to 40-45 % and 80-85 % of heart rate reserve, respectively. Blood samples were taken before and 48 hour after the exercise training period. Data were analyzed at P <0.05 level.Results:Our findings showed that there wereno significant differences in blood urea nitrogen levels (18.61±5.76 and 16.61±3.48mg/dl for pre and post exercise, respectively) (P=0.252) and creatinine (0.89±0.09 and 0.83±0.06 mg/dl for pre and post exercise, respectively) (P = 0.203) in the control group.Low-intensity exercise had no significant effect on blood urea nitrogen (17.48±2.74 and 18.61±2.89 mg/dl for pre and post exercise, respectively) (P=0.932) and creatinine (0.87±0.05 and 0.89±0.08 mg/dl for pre and post exercise, respectively) (P=0.512). In addition, high-intensity exercise had no significant effect on blood urea nitrogen (16.16±2.98 and 17.13±2.35 mg/dl for pre and post exercise, respectively) (P=0.492) and creatinine (0.86±0.11 and 0.91±0.15 mg/dl for pre and post exercise, respectively) (P=0.141). Furthermore, no significant differences were observed in blood urea nitrogen (P=0.437) and creatinine (P=0.370), betweengroups after the intervention.Discussion and conclusion:Although, one study demonstrated that 12 weeks aerobic exercise in morning and afternoon significantly reduced 24 hour urine urea in diabetic women (2), however our findings showed that endurance training with low and high-intensity for 8 weeks had no significant effect on blood urea nitrogen and creatinine.These contradictory findings probably due to the different subjects and urine samples used in thatstudy.Therefore, it is thought that low- and high-intensity endurance trainings had no dramatic effect on parameters involved in muscle protein breakdown in older women.
