Abstract PDF

BACKGROUND: English is the lingua franca of science; it is the language of the two last world superpowers and the language of four out of the world's ten greatest producers of science; it is a fairly simple language and the most hybridized language in history, with Latin and French contributing 60% of the entire English lexicon. The object of this study is to determine whether the frequency of use of imported words is a function of literary genre.
METHOD: texts were randomly selected from (a) medical scientific original articles, (b) newspaper financial reports, (c) sport reportages, (d) literary texts and (e) colloquial English; for comparison a collection of similarly distributed texts were selected from Portuguese; the frequency of occurrence of Latin or Neo-Latin words was determined in the English texts as well as the occurrence of non-Latin or non-Neo-Latin words in the Portuguese texts; a oneway analysis of variance was used to determine whether significant differences occurred between genres in the two languages.
RESULTS: The frequency of occurrence of Latin/French words in English text was significantly dependent on the literary genre, being maximal in medical scientific texts and minimal in colloquial English; in contrast, the frequency of occurrence of non-Latin words in Portuguese was constant throughout the same literary genres.
CONCLUSION: The use of Latin/French words in English is directly proportional to the complexity of the literary genre, a phenomenon not observed in Portuguese, a typical Neo-Latin language.

Abstract PDF

OBJECTIVE: To determine the reliability (stability) of the peak velocity measurement (VPeak) derived from the incremental maximal effort test, as well as to establish the possible influence of the level of training on these responses.
METHOD: Thirty-eight male volunteers made two visits (3 - 5 days apart) to the training center where the study was conducted and performed maximal progressive running tests. The protocol consisted of increments of 0.5 km.h-1/min, starting at a running speed comfortable for each participant (7-9 km.h-1). All subjects were encouraged to achieve the maximum possible performance in both tests, with final voluntary exhaustion being the criterion for interruption.
RESULTS: The intra-class correlation coefficient presented excellent consistency of measurements (ICC = 0.975 - p = 0.001). The typical relative error of the measurement was 2.6% for the stability of the measurement of VPeak. Moreover, there were no significant differences between the individual coefficients of variation for measures 1 vs. 2 (p > 0.05). Graphical representation of Bland-Altman demonstrated a homogeneous distribution of the measurement error for all dependent variables.
CONCLUSION: Determination of VPeak exhibited excellent levels of reliability with small measurement errors. There was no influence of the training level on the reliability responses.
