Exertion tests for predicting maximal oxygen uptake (VO2) intend to estimate the person maximum performance. Some articles mention the verbal encouragement in their protocol to reach it, while others do not. The objective of the present study is to observe the influence of verbal encouragement every 60 s used by a coach on maximal oxygen uptake, distances covered and final heart rate of adolescents. 12 young male volunteers (aged 16.7±0.45 years) were subjected to a multistage 20 m shuttle run test twice, with a week interval between each test. Half of the sample was given incentives during the first test, and the other half, only in the second test. Significant differences in maximal oxygen uptake (Δ% = 5.14%, p = 0.009), distances covered (Δ% = 9.23%, p = 0.03) and final heart rate (Δ% = 3.21%, p = 0.03) were observed between the two groups, with and without verbal encouragement. The verbal encouragement improved the performance in the test for the three parameters analyzed. © 2015 Eduem - Editora da Universidade Estadual de Maringa. All rights reserved. Source

Introduction. The Acute Respiratory Distress Syndrome (ARDS) is characterized as a hypoxemic acute respiratory failure generated by an intense pulmonary inflammatory response. The tracheal gas insufflation (TGI) is one of the alternative therapies for the treatment of the hypercapnia in ARDS. Method. To realize this literature review, it was utilized pneumology books and articles from the databases Bireme, Scielo and Pudmed, from 1992 to 2006, with the following key-words: Acute Respiratory Distress Syndrome, tracheal gas insufflation, permissive hypercapnia and their similar in Portuguese. Conclusion. Previous studies about the technique points to positive results in the reduction or stabilization of PaCO2, however the lack of a secure protocol and concerns about the deleterious effects still surrounds TGI. TGI is seeing as a secondary technique, but effective in the treatment of hyopercapnia in patients under protective ventilation in ARDS. Therefore, researches can still explore this technique, assisting its development and looking for better understanding of it's benefits. Source
