Metabolic syndrome status changes with fitness level change: a retrospective analysis.

Background: Cardiorespiratory fitness level is inversely related to the incidence of Metabolic Syndrome (MetS). This study examined the effects of changes in cardiorespiratory fitness level on MetS status.

Methods: Male and female participants in a health enhancement program (n = 212) were clinically examined for changes in their MetS status and estimated aerobic capacity over a 3-year period.

Reversal of metabolic syndrome characteristics.

Background: Metabolic syndrome (MetS) is a constellation of three or more clinical health abnormalities from a list of five and, therefore, can vary significantly in its profile. Successful intervention strategies for preventing or resolving individuals' MetS may benefit from better understanding how specific risk factor profiles influence improvement in syndrome status.

Methods: A retrospective analysis of clinical records for members participating in a university-based health assessment/fitness center between 1978 and 2003 was undertaken in 2005.

Longitudinal modeling of the relationship between age and maximal heart rate.

Purpose: Maximal heart rate (HRmax)-prediction equations based on a person's age are frequently used in prescribing exercise intensity and other clinical applications. Results from various cross-sectional studies have shown a linear decrease in HRmax during exercise with increasing age. However, it is less well established that longitudinal tracking of the same individuals' HRmax as they age exhibits an identical linear relationship.
