Summary of the Article
The study aimed at assessing the influence of the color of jersey on the actors participating in a combat situation. As a result, it utilized an artificial fighting situation that involved 14 pairs of athletes who fought each other twice. In the first round, they used the red jersey, and in the other, they utilized the blue ones. The type of study under investigation was experimental. The author notes that "an artificial, experimental combat situation was created in which the color of the sports attire was assigned randomly” (Dreiskaemper et al. 2013). The experiment utilized both the independent and dependent variables. An independent variable is subject to manipulation during scientific experimentation. The dependent variables are the parameters under scientific experiment (Casler, 2015). The independent variable in the study was the jersey color while the independent variables included the heart rate and strength. The 28 participants in the study were collected randomly. Although there was no significant correlation between jersey color and combat, a relationship was seen in heart rate and strength. Athletes wearing the red jersey recorded a higher strength and heart rate than those with the blue ones.
Critique of the Study
Barker and Milivojevich (2016) asserted that a study is regarded as reliable if the assessment tool is in a position to produce not only stable but also consistent results. On the other hand, validity describes how well a test attempts to measure the intended measurements. As seen in the procedure and results, the experiment is both reliable and valid because the tests are standardized and also produce consistent results that can be tracked over time. The interpretation of the results was however biased. Although the author concludes that the fighters are significantly affected by their jersey color, he or she casts a blind eye on other confounding factors such as preference, tastes, and beliefs. The experiment significantly took cognizance of all the ethical guidelines. First, there is no evidence showing that the participants were coerced into the experiment. Secondly, all the participants had to provide critical information regarding their physical fitness and most importantly, the willingness to take part in the study. Also, personal information was not publicized.

A follow-up study that I would conduct to build on the findings of the research would be based on the question: How jersey color preference affects the performance of combat sports athletes. The study would attempt to assess how beliefs and perceptions about a given color ultimately affected the overall output. Using blue and red as the colors, athletes with a preference to red would be given blue and vice versa. After each of the participants wears a color that is not their favorite, their heart rate and strength will then be measured. The study will help to analyze if the color preference has a critical role in determining how well a person engages in a combat sport. I believe that the results found in the study are neither stronger nor weaker compared to the claim. The outcomes remain within the scope of the research question. As earlier intimated, the method used in the article to assess effectiveness in combat sport would have been made better if it took cognizance of the position of beliefs and color preferences.
Brief Summary
The authors, Hill, and baryon wanted to show that combat sports participants in wrestling, boxing, and tae kwon do who wore read often women in the 2004 Olympic Games in comparison to those who wore blue. Therefore, the study aimed at assessing the effect that jersey color had on the physical aspects of the athlete including the heart rate and strength. As a result, an artificial fighting experiment was created where participants where participants were randomly assigned the blue and red jersey colors. The measurement of these two physical parameters thereafter followed.
