Association of muscular strength with incidence of metabolic syndrome in men.
To examine the association between muscular strength and incidence of metabolic syndrome. ⋯ Muscular strength was inversely associated with metabolic syndrome incidence, independent of age and body size. Potential benefits of greater muscular strength presumably through resistance exercise training should be considered in primary prevention of metabolic syndrome.

Chronic fatigue syndrome: exercise performance related to immune dysfunction.
To date, the exact cause of abnormal exercise response in chronic fatigue syndrome (CFS) remains to be revealed, but evidence addressing intracellular immune deregulation in CFS is growing. Therefore, the aim of this cross-sectional study was to examine the interactions between several intracellular immune variables and exercise performance in CFS patients. ⋯ These data provide evidence for an association between intracellular immune deregulation and exercise performance in patients with CFS. To establish a causal relationship, further study of these interactions using a prospective longitudinal design is required.

Comparative Study Controlled Clinical TrialExercise and cognitive performance in chronic fatigue syndrome.
To determine the effect of submaximal steady-state exercise on cognitive performance in patients with chronic fatigue syndrome (CFS) alone, CFS with comorbid fibromyalgia FM (CFS + FM), and sedentary healthy controls (CON). ⋯ CFS patients without comorbid FM exhibit subtle cognitive deficits in terms of speed, consistency, and efficiency that are not improved or exacerbated by light exercise. Importantly, our data suggest that CFS + FM patients do not exhibit cognitive deficits either pre- or postexercise. These results highlight the importance of disease heterogeneity in studies determining acute exercise and cognitive function in CFS.

Biochemical and hormonal responses during an intercollegiate football season.
Changes in biochemical indices of muscle damage and hormonal markers of stress were examined during a competitive intercollegiate football season. ⋯ CK elevations seen during T2 appear to reflect the high intensity and physical nature of training camp. However, biochemical and endocrine responses during a season of intercollegiate football competition suggest a degree of sensitization (contact adaptation) of the muscles relating to the repeated traumas occurring during the season.
