Vasomotor Activity

The heart period (R-R) variability power spectrum presents two components, at low (LF; approximately 0.10 Hz) and high (approximately 0.25 Hz) frequencies, whose reciprocal powers appear to furnish an index of sympathovagal interaction modulating heart rate. In addition, the LF component of the systolic arterial pressure variability spectrum furnishes a marker of sympathetic modulation of vasomotor activity. The contribution of spinal and supraspinal neural circuits to the genesis of these rhythmic oscillatory components remains largely unsettled. Therefore we performed spectral analysis of R-R and systolic arterial pressure variabilities in 15 chronic neurologically complete quadriplegic patients (QP) and in 15 control subjects during resting conditions, controlled respiration, and head-up tilt. At rest, in seven QP the LF component was undetectable in both cardiovascular variability spectra; in two QP this component was present only in R-R variability spectrum, whereas the remaining six showed a significantly reduced LF in both signals. In QP, the LF component, when present, underwent paradoxical changes with respect to controls, decreasing during tilt and increasing during controlled respiration. In five QP in whom the recording session was repeated after 6 mo, a significant increase in LF was observed in both variability spectra. These data confirm the finding that a disconnection of sympathetic outflow from supraspinal centers can cause the disappearance of the LF spectral component. However, LF presence in some QP supports the hypothesis of a spinal rhythmicity likely to be modulated by the afferent sympathetic activity.

Diet And Physical Activity

The research has included 422 patients aged between 25 to 60, of whom 341 were men and 81 women. The purpose of research was to determine impact of diet and physical activity in the treatment of metabolic syndrome during the six month period.Processing of results through descriptive and discriminative analysis have indicated that 6 month treatment with diet and physical activity have had an impact in the: waistline decrease by 6,05 cm or 5,50% among males, and 4,92 cm or 5,10% among females; body mass index (BMI) decrease by 1.78 or 6.20% among males, and 2,3 or 8,16% among females; decrease of blood triglycerides levels by 0,35 mmol/L or 16,28% among males, and 0,27 mmol/L or 13,30% among females; increase of blood cholesterol HDL-C by 0,48 mmol/L or 34,78% among males, and 0,06 mmol/L or 4,28% among females; systolic arterial pressure decreased by 15 mmHg or 10,18%, and diastolic blood pressure by 8,74 mmHg or 9,47% among males, and systolic arterial pressure decreased by 7,39 mmHg or 5,17%, and diastolic blood pressure decreased by 5,18 mmHg or 5,75% among females; the level of blood glucose decreased by 0,45 mmol/L or 7,04% among males, and by 0,64 mmol/L or 9,92% decreased among females.The results show that physical exercise and diet are important factors in reducing the values symptoms of metabolic syndrome.In order to improve symptoms of metabolic syndrome, it is necessary to keep on with healthy diet and physical exercise that means the change of lifestyle.
