Efeito de um mês de destreinamento sobre a aptidão física relacionada à saúde em programa de mudança de estilo de vida

Physical exercise induces hemodynamic/ventilatory and neuromuscular adaptations that can be reverted with interruption of the training program. The aim of the present study was to evaluate the effect of detraining on physical fitness related to health. Forty-four healthy subjects, both male and female, aged 57.6±8.9 years performed the 'Mexa-se Pró-Saúde' protocol with nutritional orientation and supervised physical exercises for nine months. The program consisted of aerobic, localized muscular endurance and flexibility exercises, with duration 80 minutes/session, five days/week. Only subjects who participated in the program for more than three days/week have been selected. The detraining period was one month. Weight (kg) and height (m) were measured and the body mass index (BMI) calculated. Additionally, motors tests to evaluate the flexibility (FLEX), strength of lower limbs (SLL) and upper limbs (SUL), and maximal oxygen uptake (VO2máx) were conducted in the beginning of the study (MI), after nine months of practicing (MT) and after detraining period (MD). ANOVA (p<0.05) and Tukey test to show the difference between groups when it evidence were used for statistical treatment. The results showed that the gains of 22% and 7% on SLL and VO2máx respectively, obtained with the training, have not changed during the detraining period; however, the flexibility gain of 8% returned back to baseline after the detraining period. BMI and SUL did not change during the study. Although the lower limbs strength gains and maximal oxygen uptake obtained have been kept, one month of detraining was enough for losing the flexibility acquired.

Application of landsat images for quantifying the energy balance under conditions of land use changes in the semi-arid region of Brazil

In the Nilo Coelho irrigation scheme, Brazil, the natural vegetation has been replaced by irrigated agriculture, bringing importance for the quantification of the effects on the energy exchanges between the mixed vegetated surfaces and the lower atmosphere. Landsat satellite images and agro-meteorological stations from 1992 to 2011 were used together, for modelling these exchanges. Surface albedo (α0), NDVI and surface temperature (T0) were the basic remote sensing retrieving parameters necessary to calculate the latent heat flux (λE) and the surface resistance to evapotranspiration (rs) on a large scale. The daily net radiation (Rn) was obtained from α0, air temperature (Ta) and short-wave transmissivity (τsw) throughout the slob equation, allowing the quantification of the daily sensible heat flux (H) by residual in the energy balance equation. With a threshold value for rs, it was possible to separate the energy fluxes from crops and natural vegetation. The averaged fractions of Rn partitioned as H and λE, were in average 39 and 67%, respectively. It was observed an increase of the energy used for the evapotranspiration process inside irrigated areas from 51% in 1992 to 80% in 2011, with the ratio λE/Rn presenting an increase of 3 % per year. The tools and models applied in the current research, can subsidize the monitoring of the coupled climate and land use changes effects in irrigation perimeters, being valuable when aiming the sustainability of the irrigated agriculture in the future, avoiding conflicts among different water users. © 2012 SPIE.

The need of subsidy for the implementation of photovoltaic solar energy as supporting of decentralized electrical power generation in Brazil

The growing demand for electrical power and the limited capital invested to provide this power is forcing countries like Brazil to search for new alternatives for electrical power generation. The purpose of this paper is to present a technical and economic study on a 15 kW solar plant installed in an isolated community, highlighting the importance of the need for financial subsidy from the government. It evaluates the importance of parameters such as the annual interest rate, specific investment, the marginal cost of expanding the electrical power supply and the government subsidy on amortization time of capital invested. © 2012 Elsevier Ltd All rights reserved.
