Editorial: Research bias in exercise physiology
In this December 2005 issue there is a Letter to the Editor from Carpinelli (1) concerning a manuscript by Kraemer (2) and further evidence of bias in research review and scientific scholarship on the topic of resistance exercise training guidelines and recommendations. This topic and the letter content are an extension of the prior critical review by Carpinelli et al. (3) of recent recommendations and guidelines in resistance training (4). I reviewed the submitted letter, recommended several edits, and approved of the final version. I need to accompany the Letter to the Editor with an editorial so that science can be revealed to be the true beneficiary of this on-going interchange..
Editorial: A call to duty
As many of you have known for a couple of years, I have had a hard time keeping up with the increasing work required as editor-in-chief of JEPonline. This year revealed this difficulty, and it became obvious that it was time to hand over the editor-in-chief responsibility to someone new..
A review of the stroke volume response to upright exercise in healthy subjects
Traditionally, it has been accepted that, during incremental exercise, stroke volume plateaus at 40 of VO2MAX. However, recent research has documented that stroke volume progressively increases to VO2MAX in both trained and untrained subjects. The stroke volume response to incremental exercise to VO2MAX may be influenced by training status, age, and sex. For endurance trained subjects, the proposed mechanisms for the progressive increase in stroke volume to VO2MAX are enhanced diastolic filling, enhanced contractility, larger blood volume, and decreased cardiac afterload. For untrained subjects, it has been proposed that continued increases in stroke volume may result from a naturally occurring high blood volume. However, additional research is needed to evaluate the importance of blood volume, or other mechanisms, that influence the stroke volume response to exercise in untrained subjects
Last word on point: Counterpoint: Stroke volume does/does not decline during exercise at maximal effort in healthy individuals
This pro-and-con debate expects the presenters\ud
to advance polarized views on whether stroke volume declines\ud
during exercise at maximal effort in healthy individuals not to\ud
provide a balanced assessment of the literature, as Drs. Warburton\ud
and Gledhill appear to contend (3)..
