Resting metabolic rate and post-prandial thermogenesis by level of aerobic power in older athletes.
No full text1. The aim of the present study was to evaluate the resting metabolic rate (RMR) and thermogenic effect of a meal (TEM) in older athletes. 2. Eighteen older male volunteers were divided into three groups according to their aerobic power related to fat-free mass (FFM) as follows: (i) group I, high aerobic power (Vo(2max) > 70 mL/kg FFM per min); (ii) group II, moderate aerobic power (Vo(2max) = 55-70 mL/kg FFM per min); and (iii) group III, low aerobic power (Vo(2max) < 55 mL/kg FFM per min). 3. The RMR values, covariated for FFM using analysis of covariance (ancova), were higher in group I (mean (+/-SEM) 1.09 +/- 0.04 kcal/min) than in groups II and III (0.99 +/- 0.05 and 0.91 +/- 0.03 kcal/min, respectively). Group I had a tendency for higher mean TEM values compared with the other groups, but the differences were not statistically significant for absolute or percentage values. 4. Master endurance athletes with high aerobic power exhibit a higher RMR than master endurance athletes of similar age and body composition but with lower aerobic power
Morphofunctional modification in elderly individuals practicing competitive endurance sport.
No full textTo investigate the modification of body composition and level of aerobic capacity in older athletes practicing competitive sport for two years consecutively, 20 elderly male endurance athletes (A) were compared with twenty elderly male subjects who practiced moderate exercise (C). Body composition analysis, physical activity and maximal aerobic power (VO2max) were measured at the beginning of the study, after twelve months and after twenty-four months in both groups. We observed significant differences in group A: body fat was significantly lower in the subjects at the first and second year than at the beginning of the study; fat-free mass (FFM) was significantly higher in the subjects at the first and second year; VO2max in every measurements was significantly higher in the subjects at the at the first and second year than at beginning of the study. Our data suggest that it is possible, even in the elderly, to reach a good level of physical fitness with appropriate training protocols for competitive sport
Adenosine Coronary Vasodilation in Coronary Artery Disease: Technetium-99m Tetrofosmin Myocardial Tomography Versus Echocardiography
No full textAbstract
This study compared the results of adenosine 99mTc-tetrofosmin cardiac tomography with those of adenosine echocardiography in identifying patients with coronary artery disease (CAD) and in localizing individual stenosed, coronary vessels.
METHODS:
Twenty-six consecutive patients with suspected or known CAD had simultaneous adenosine (140 micrograms/Kg/min intravenously) 99mTc-tetrofosmin tomography and two-dimensional echocardiography. All patients had coronary angiography within 4 wk from imaging studies. Regional 99mTc-tetrofosmin activity was quantitatively measured in 78 coronary vascular territories and echocardiographic left ventricular function was assessed in corresponding regions.
RESULTS:
At coronary angiography one patient had normal coronary vessels, 12 patients one-vessel and 13 had multivessel disease (> or = 50% luminal stenosis). Among the 25 patients with CAD, 22 showed perfusion defects at adenosine 99mTc-tetrofosmin tomography (sensitivity 88%) and 17 had abnormal echocardiographic study (sensitivity 68%, p < 0.05 versus 99mTc-tetrofosmin). Agreement for the identification of patients with CAD between adenosine 99mTc-tetrofosmin tomography and echocardiography was observed in 21 (81%) of the total 26 patients, with a kappa value of 0.45. Overall sensitivity, specificity and diagnostic accuracy for detection of individual stenosed vessels were 79%, 88% and 83% for 99mTc tetrofosmin and 57%, 68% and 61% (all p < 0.05 versus 99mTc-tetrofosmin) for echocardiography. Concordance between adenosine 99mTc-tetrofosmin tomography and echocardiography in the detection of individual stenosed coronary vessels was observed in 57 (73%) of the 78 vascular territories, with a kappa value of 0.36.
CONCLUSION:
Adenosine-induced coronary vasodilation associated with quantitative 99mTc-tetrofosmin tomography is more accurate than adenosine echocardiography in identifying patients with CAD and in detecting individual stenosed coronary vessels
Wastes management in Province of Torino
No full textWaste disposal in Province of Torino is atypical respect to other Provinces of northern Italy since it is still based on landfilling. In order to redesign waste management, in 1997 source separation of waste was promoted according to a "road" ("stradale") modality, which has yielded not so homogeneous and satisfactory results. For this reason, in order to improve the separate collection, the "door to door" ("porta a porta") modality has been activated in last years and it is in course of experimentation. The present work shows the analysis of source separation trend in the Province on the basis of results obtained between 1997 and 2004. This allowed to develop a model to interpret and foresee source separation evolution. Moreover, on the basis of the working plants available in the Province territory, the model also allows to plan the necessity of new plants in particular regard to biological one
Evaluation of Left Ventricual Asynchrony by Radionuclide Angiography: Comparison of Phase and Sector Analysis
No full textAbstract
The aim of this study was to assess the optimal method to evaluate asynchrony in equilibrium radionuclide angiography (RNA).
METHODS:
We studied 20 patients (14 males and 6 females, age range 25-60 yr) with RNA during atrial and sequential atrioventricular (AV) pacing, which increased left ventricular (LV) asynchrony. Both studies were performed at the same heart rate. Asynchrony was assessed either on phase images, by computing the standard deviation of the phase distribution (SD-P) and by sector analysis. Systolic and diastolic asynchrony were evaluated as the coefficient of variation of time to end systole (CV-TES) and time to peak filling rate (CV-TPFR) in four sectors. In addition, phase values were computed on time-activity curves from the same sectors, and their standard deviation (SD-Psec) was computed.
RESULTS:
During atrial pacing SD-P was 32.3 degrees +/- 6.7 degrees and did not change during AV pacing (32.1 degrees +/- 5.6 degrees, p = n.s.). Both CV-TES and CV-TPFR had a significant increase during AV pacing (from 7.7% +/- 3.9% to 11.5% +/- 6.4%, p < 0.01, and from 8.4 degrees +/- 5.8 degrees to 12.9 degrees +/- 6.7 degrees, p < 0.001). AV pacing led to a significant increase in SD-Psec (from 6.3 degrees +/- 4.0 degrees to 12.6 degrees +/- 9.7 degrees, p < 0.05). Moreover, reproducibility was assessed in 15 additional age-matched patients. The results of the reproducibility study indicate a better repeatability for CV-TES and CV-TPFR.
CONCLUSIONS:
The findings of this study suggest that sector analysis with calculation of indices of LV systolic and diastolic asynchrony is better suited for quantitation of LV temporal nonuniformity
