Sample Article Review on Diuretics and Nutritional Supplement

Article Review on Diuretics and Nutritional Supplement

Ergogenic aid is a substance or a technique used to enhance performance. This article review focuses its attention on diuretics and potassium supplements. The first article addresses itself to diuretics while the second article addresses itself to potassium supplements. The potassium supplements are nutritional while diuretics considered in this case are drugs. Based on this fact, the two types of aid are able to improve body performance by altering the way the body functions (Szczesna-Kaczmarek, 2013). Theoretically, this aid may enhance the way athletes perform. This article review evaluates the side effects ergogenic aid together with nutritional supplement may have on athletes.

In terms of experimental procedures, the first article had nineteen research participants. These research participants engaged in cycling exercises every morning for their blood and urine samples to be taken for analysis purposes (Szczesna-Kaczmarek, 2013). The second article utilized cross-sectional research method. The research participants were selected from Caucasian patients with advanced kidney failure. During the selection period, the research participants were not on significant nutritional changes. In addition, they had not begun dialysis or even undergone through kidney transplant. The samples were collected on a daily basis after overnight fast and conventional methods were used in laboratory tests. The study had both study group and control group given that one group of patients was treated with diuretics while the other group was not treated with diuretics (Caravaca et al., 2013). This study could have been a single-blind one because the authors were investigating the effects of diuretics without the knowledge of research participants.

In a simple language, athletes’ plasma potassium concentrations for the first article increased from 5.46 ± 0.40mmol/L to 6.65 ± 0.90mmol/L, but after five minutes returned to their normal concentrations. The increment in potassium was correlated to the changes in blood. The mean weight, height, and ages for the research participants were 83.4 ± 6.5 kg, 180.9 ± 5.8 centimeters and 22.5 ± 1.16 years respectively (Szczesna-Kaczmarek, 2013). For the second article, the mean age for the research participants was 67 ± 14 years. 53 percent of the research participants were males while 47 percent of them were females. In terms of serum phosphate concentration, there was significant difference between patients treated with diuretics and those treated without diuretics. Phosphate re-absorption rate was also significantly different for the two groups even though there were no significant differences in the excretion rates (Caravaca et al., 2013).

For the first article, the author did not publish her statistical results in an organized manner. Based on this fact, a person finds it difficult to follow the study’s result. With regard to methodology, the second article did not categorically indicate how it went about selecting its study group. The article only indicated that one group of patients was treated with diuretics while the other group was not treated with diuretics. In addition, the number of patients that were treated with diuretics was 58 percent while the number of patients that were not treated with diuretics was 42 percent (Caravaca et al., 2013). The authors did not indicate how they dealt with this issue. This notwithstanding, the article review does not establish any placebo effect in the second article.

The findings from the two articles are applicable to athletes. On one hand, the findings from the first article demonstrate how athletes can stabilize concentration of potassium ions in their bodies before and after they engage in physical exercises (Szczesna-Kaczmarek, 2013). On the other hand, the findings from the second article demonstrate how diuretics may interfere with the kidney’s capacity to excrete phosphates. Overall, both findings are instrumental to athletes because while they acknowledge the role supplements play in the body, they acknowledge the fact that those supplements can also be harmful to the body. In this respect, the amount of supplements that athletes should take to enhance their performances should be relatively small, but adequate. This means that the cost for the aid may be slightly low. In terms of side effects, some supplements may have detrimental effects on athletes (Hoffman, 2014). Therefore, even if I would recommend diuretics and potassium supplements to athletes, I would advise them to take precautionary measures as they take these supplements.
