Article Summary: Protein Nutrition and Endurance Exercise: What Does Science Say? Certainly, there is overwhelming evidence supporting a strong relationship between nutrition and body performance especially in athletes. However, recent evidence provide mixed results as to the direct relationship between specific intake of proteins and carbohydrates. The summarized article sourced from Gatorade Sports Science Institute Online Library discusses the correlation between protein intake and body performance in relation to muscle recovery.
Carbohydrate-electrolyte beverage (CEB) is believed to boost body performance during heavy performance when given in a specified formula. According to scientists, the CEB works by delivering two main ingredients, carbohydrate (CHO) and sodium. While carbohydrate supplies energy, sodium assists in maintaining electrolyte balance. Claims have been made that an approximate 2% protein in a CEB boosts endurance during performance. However, these findings have been questioned since the tests were not carried out in the real aspect of athlete performance. For instance, taking a substance to mimic dehydration and fatigue could have different impact on different athletes hence compromising the findings.
More interestingly is the findings that consumption of specific amino acids actually boosted body performance during exercise. For instance, branched-chain amino acid (BCAA) provided no tangible benefits to performance. However, such findings are also questionable since manipulation of body condition may not have reached athlete performance conditions.
However, research on effect of protein intake in recovery phase and acute muscle adaptations seemed to yield acceptable and more and realistic results. According to the research carried out, consuming protein with CHO came in handy in promoting muscle repair and recovery after heavy exercise. This could have been attributed to a more specified effect of amino acids especially BCAA on signaling pathways that control muscle protein synthesis. However, questions have been raised over the issue of glycogen resynthesis after consumption of protein-CHO mixture. Fact that is more acceptable is that higher intake of CHO at higher frequencies compromises the benefits of such intake. Arguably, taking protein with CHO on glycogen may supply more energy rather than produce an effect of muscle recovery.
Following the controversy over the specific boost to endurance in body performance during heavy exercise is the intake of protein with CHO. It is argued that intake of ingesting a CHO-protein mixture during recovery phase may boost endurance not because of specific input of proteins but rather due to increased intake of energy supplied by CHO. Nevertheless, many research findings yielded the same results of improved endurance on intake of protein-CHO based drinks. One notable fact about many of these findings is that more elucidative findings need to be carried out especially when it comes to making accurate conclusion on the specific nutritive content responsible for improved performance or endurance.
Presently, there is little evidence to prove that consuming protein with CHO has any meaningful improvement on subsequent athlete exercise. The only acceptable and promising research findings are the one supporting the positive contribution of protein intake on muscle recovery after exercise. Therefore, in the endeavor to improve athlete recovery especially for heavy sporting activities, it is advised that a protein with CHO can be of great use. Conclusively, approximately 10 to 20 grams of protein with CHO after strenuous exercise promotes muscle protein synthesis compared to CHO. More importantly, such an intake may go a long way in improving performance especially in long-term training.

... Module Summary ARTICLE Stell, Lance K. ‘The Production Of Criminal Violence In America: Is Strict Gun Control The Solution?’ The Journal of law, Medicine and Ethics. 32:1. (2004). Print. In the article, the author defines Strict Gun Control (SGC) as a group of activities that are defined to cause firearm scarcity among people (Stell 38). The gun control policy rests on the premise that dangerous gangs are the only ones responsible for causing violence; but also the situation may also be lethal if the guns are left in the hands of innocent civilians. The article makes reference to one of the most prolific theorists, Professor Zimring’s idea of advocating for gun scarcity among the population since 1969. This helps in demonstrating... ...

...Summary of Articles Clark Kerr, in his “The Uses of the ” considers the importance of research colleges in our society. While Kerr believes that all colleges are important in shaping young people to become productive members of society, he also believes that research colleges should be receiving a little more attention. This is primarily due to the fact that research colleges aid science, technology, and medicine fields. The overall change that Kerr wants to see in research colleges is that they become more intellectual and specialized. Other four-year colleges exist for students of other majors, but science and health majors can be most useful to society and to the economy....

...Meta-analysis Meta-analysis Anomia treatment efficacy depending on aphasia type, severity, and therapy amount In the treatment of anomia, the meta-analysis evaluation was conducted which focused on the efficiency of therapy for anomia because of aphasia. It mainly focused on calculating the effect size of the therapy. The study focused moderator variables such as type of treatment, follow up measure, word set and time post onset. The results depicted a substantial distinction in effect size depending upon whether the confrontational naming task involved a trained or untrained word set or not. The purpose of this meta-analysis extends the previous research by evaluating these anomia studies to focus on the efficacy of treatment... Meta-analysis...

...Summary: The nature of public opinion Patterson Thomas ed the article, ‘The nature of public opinion,’ in which he defines public opinion as the open expression of privately held political opinion on an issue in the society. Such expressions further qualify as public opinion if ordinary people make them and not special parties such as politicians or expert policy makers. Governance by public opinion, according to the author, remains a challenge because of limitations that public opinion faces. One of the limitations is that people hold different opinions on an issue at a given time and this compels the government to support and implement opinions from a side but reject opinions from another side. Opinions may also be...
