Input: Consider Input: Question: Is translation of questionnaires measuring health related quality of life standardized : a literature based research study?
Answer: This study shows that there seems to be a consensus regarding the translation process (especially for internal validity) although most researchers did not use a translation guide. Moreover, we recommended that clinical researchers should consider three steps covering the process of translation, the qualitative validation as well as the quantitative validation.

Input: Consider Input: Question: Do veteran athletes exercise at higher maximum heart rates than are achieved during standard exercise ( stress ) testing?
Answer: Maximal HR in veteran athletes during specific sporting activities was significantly higher than that attained during a routine sECG. This finding was not sport-specific, nor was it related to the level of competitiveness of the trial participants. These data show that a routine sECG is a submaximal test of exercise performance, and should be interpreted as such.


Output: yes
