In the present article, Nguyen, Tran, and Duoos (2016) briefly describe the results of the research they conducted to study the influence of magnesium in comparison with potassium supplementation on SBP during aerobic-cycling exercise. They point to the gap in the studies concerning potassium and magnesium supplementation and address the effects of the new approach without emphasizing the expected outcomes.

The study was carried out objectively: magnesium and potassium capsules were distributed blindly and randomly, and the control and experiment groups were present (Nguyen et al., 2016). In the process of the research, heart rates at rest, posttest, and recovery were measured and recorded. However, the fact that the subjects themselves were responsible for registering their potassium and magnesium taking gives ground to be more careful in the assessment of the results.
The researchers describe the method and point out that a two-sampled t-test was done to compare pretest and posttest results within each supplementation group (Nguyen et al., 2016). According to the authors, a considerable difference between the two groups was registered via a one-way analysis of variance. The researchers conclude that potassium supplementation proves to lower exercise BP to a large extent in contrast with the pretest and posttest rates.
The article is laconic and, to some extent, lacks details. Although the main points are covered, one still needs more explanation of the key points. The theoretical part also seems necessary. It was probably the volume of the article that imposed some limitations. In this regard, the article may be considered satisfactory for those who need concise information about the usage of magnesium and potassium. Besides, this article may be used to understand the current trends in potassium supplementation and blood pressure research.
