Abstract

Background & Aims: Taurine has several biological and physiological roles in athletes and active individuals. It can protect against oxidative stress in a variety of conditions and act as an anti-inflammatory agent. Taurine has several biological and physiological roles in athletes. Due to the numerous effects associated with the action of Taurine in the human body, some researchers have tried to identify the relationship between this micronutrient and physical exercise. More research is needed to determine which population groups can benefit most from Taurine supplementation, and it is necessary to study on participants with different age, health, and exercise status. Also, the effect of Taurine supplementation on the response of cardio-metabolic indicators to an exhaustive exercise session in active men is another subject that has been less studied so far. The purpose of this study was to investigate the effects of Taurine supplementation on some cardiometabolic parameters and components of physical fitness at rest and following an exhaustive exercise session in active men. Methods: The research method was quasi-experimental with pre-test and post-test assessments and twenty active men with an experience of at least two years of regular training were selected from among taekwondo players in the city of Saghez and were randomly divided into two experimental (supplementation, n=10) and control (placebo, n=10) groups. The research was done via available sampling and the subjects were randomly assigned to the groups. The assessments were carried out in three stages (pre-supplementation, post-supplementation, and immediately after an exhaustive exercise session). Pre-test evaluations were performed on two consecutive days at about 8 a. m. On the first day, resting Blood Pressure was measured and a blood samples (10 cc) of the volunteers were taken from a brachial vein in a sitting position. Bruce treadmill test was immediately performed to assess Aerobic Power (cardio-respiratory function). Then, the anthropometric and physiological characteristics of the volunteers including height, weight, body mass index and body fat percent were measured. Also, chest press and leg press tests were performed to evaluate muscle strength. On the second day, RAST (running-based anaerobic speed test) was performed to assess anAerobic Power and then the curl up and chin up tests were performed to assess muscular endurance. The period of supplementation was fourteen days. Each day before breakfast and dinner, the experimental group received two 2-gram capsule of Taurine and the placebo group consumed four grams of starch in the same period. During the supplementation period, subjects in both groups performed their routine exercise program under the supervision of a trainer. The training program included general and specialized taekwondo exercises, three days a week. The duration of each training session was approximately 90 minutes, including 10 minutes of warm-up, 70 minutes of special taekwondo exercises and 10 minutes of cool-down. Post-test evaluations were performed 48 hours after the supplementation period. Bruce treadmill test was used as an exhaustive exercise session and immediately, the third blood samples were taken. To analyze the data, analysis of variance with repeated measurements was used at the significant level of p<0. 05. Results: A period of Taurine supplementation had no significant effect on Aerobic Power, muscle endurance, anAerobic Power, muscle strength, Blood Pressure, body fat percent and Lipid Profile in active men (p>0. 05), but decreased levels of glucose (p=0. 001), insulin (p=0. 003) and Insulin Resistance (p=0. 001). Also, Taurine supplementation had no effect on the response of Lipid Profile, glucose, insulin and Insulin Resistance to an exhaustive exercise session in active men (p>0. 05). Conclusion: Supplementation of Taurine for fourteen days (four grams per day) does not appear to affect physical fitness components, Blood Pressure, body fat percent, and Lipid Profile levels at rest and following an exhaustive exercise in active men, but decreases resting levels of glucose, insulin and Insulin Resistance. These findings are consistent with the results of some previous research and not with others. The inconsistency of the findings of the present study with previous research can be attributed to the methodological differences of these studies such as cardio-metabolic and physical fitness components have been studied, health status of subjects (healthy or non-healthy), time interval between the end of the supplementation period and performing assessments, the length of the supplementation period (short or long term) and the species of subjects (mouse, human, etc). Carrying out similar studies in other demographic groups (e. g. sedentary men or cardiovascular patients), on a number of other indicators of physical or cardiovascular function, with different doses/periods of Taurine supplementation or with physical exercise intervention can provide new research fields for researchers and augment existing knowledge in this field.
