Heart rate variability and intensity of habitual physical activity in middle-aged

Article Abstract:

A comparison of the heart rate variability (HRV) indexes in three groups of subjects presenting different long-term physical activity profile, sedentary subjects (SED) with low-energy expenditure (PAEE) and two groups of subjects with equivalent moderate PAEE, but differing in terms of intensity of physical activity is presented. In older adults with different lifestyles, habitual moderate PAEE is associated with better self-estimated overall health status and higher vagal-related HRV indexes compared with subjects with low PAEE.

Predictors of isotonic exercise in patients with heart failure

Article Abstract:

This article examines factors associated with isometric exercise performance among patients diagnosed with heart failure. Findings indicate that resting measures of diastolic blood pressure, pulmonary capillary wedge pressure, and perceived exertion are significant predictors of performance on isometric weight-lifting tasks in this population.

Cardiovascular tolerance of healthy elderly subjects to weight-lifting exercises

Article Abstract:

This article examines hemodynamic and cardiovascular changes in elderly subjects after completing a series of weight-lifting exercises. Findings indicate that the intense exercise session resulted in significant increases in heart rate and blood pressure but were well-tolerated in elderly subjects.
