An Inside Look: May 2011 Medicine & Science in Sports & Exercise® The May issue of Medicine & Science in Sports & Exercise® (MSSE) is available online now. ACSM members can access the journal for free – simply log in at the ACSM website and click “My ACSM.” MSSE Editor-in-Chief Andrew J. Young, Ph.D., FACSM offers his insights into the May issue: “This month, we feature Hagberg et al.’s review of the most significant recent research published in 2010 on the genomics of exercise, fitness, and performance, the second of this annual series under the direction of Dr. Claude Bouchard for MSSE. In our print edition, an accompanying commentary from an invited guest editor reflects on an important implication of the review, and I recommend that you read them both. “Elsewhere in this month’s issue, Gualano et al., report that a randomized, double-blind study demonstrated that dietary supplementation with creatine, improved glycemic control in type 2 diabetic patients participating in a an exercise program when compared to effects observed in placebo-treated patients, probably attributable to an increase in GLUT-4 recruitment to the sarcolemma. Whether these findings have treatment applications, as suggested by the authors, requires results from additional, expanded clinical trials. Also this month, we feature an article by McLoughlin et al., in which both self-report and objective assessment methods were used to document that women diagnosed with fibromyalgia are significantly less physically active than a similar group of healthy controls. This finding is novel, in that previous studies on this patient population have failed to report such an effect, which the authors attribute to inappropriate positioning of accelerometry devices in those studies. “The question of sensor location is but one of the many methodological issues that have been debated by scientists interesting in obtaining valid, objective assessments of physical activity levels and patterns in different human populations, and our journal has been prominent in publishing these papers. A literature search on "physical activity" and "accelerometry" revealed that MSSE has published nearly 100 papers on the topic, which, collectively, have been cited almost 2400 times. MSSE’s single most frequently cited original research article reporting validation of accelerometry methodologies for assessing physical activity levels in free-living populations was authored by Dr. Kathleen Janz [Med Sci Sports Exerc. 1994;26(3): 369-75], and cited 160 times during the 16 years since publication. We are featuring this article from our archives for your review again this month.”
