Currently individuals are affected by a routine busy and they don't have time for physical activity, highlighting the sedentary lifestyle, a risk factor for cardiovascular diseases. For this reason, it focuses too much on cardiovascular diseases and the importance of physical practice. With the largest divulgation and variety of physical activities, activities that were not as practiced became popular, as is the case of resistive exercise. Much is said of the influence of resistance exercise in physical strength, in muscle development and in the quest for a more defined body. However, studies have shown beneficial contributions of resistance exercise on the cardiovascular system. During the physical effort, some changes occur in the body in order to meet the increased demand for oxygen. Among them is the increase in heart rate (HR), which varies with the intensity of effort. Thus, this research sought to contribute with an analysis of the HR behavior before, during and after 3 sets of hypertrophy, as far for the flexor group of the elbow as to the extensor group. It was observed that, although the HR has increased in the course of the series, the variations of HR were not significant between the flexor group and extensor group of the elbow joint. Also were not significant the differences between the variations of the HR from the 1ª to the 2ª series between the flexor group and extensor group, as well as to the variations from the 2ª to the 3ª series

In massal rearing of natural enemies with the goal of biological control, the procedures adopted for establishment and maintenance of the individual founders of the colonies may have undesirable effects on population genetic structure of laboratory. This situation influences the success of rearing and effectiveness in the field. The objective of this study was to evaluate, along of generations two laboratory populations (Jaboticabal and Piracicaba) of Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae), founded with different numbers of adults (1, 5, 10, 15 and 20 couples), the frequency of morphological variants, size of wings and eye color, such as parameters for inferences about the homozygosity degrees. For eye color were assessed the frequency, while for the size of wings was measured the width and the length of the right mesothoracic wings. The eye color variants for C. externa populations may be monitored in the laboratory aiming at detecting inbreeding, whereas the measurements of length and width of wings should not be adopted for this purpose.

This work presents an analysis of the pattern variation of the sky conditions in Botucatu/SP. The classification was based on the clarness index KT. It was used in the classification a database of global solar irradiance in the horizontal, measured at Radiometric Station of UNESP in Botucatu (latitude 22.85°S, longitude 48.43°W, altitude 786 m) from 1996 to 2005. We analyzed the variations in frequency, during the photoperiod and over the year, of the sky conditions: I - Cloudy (KT < 0.35); II - party cloudy with dominance for the diffuse (0.35 < 0.55 < KT)) III - party cloudy with dominance for the clear (0.55 < KT < 0.65) and IV - clear (KT > 0.65). The frequency of sky conditions I and II are higher during the rainy season of the year and in hours close to sunrise and sunset. And it is lower during the dry season an in hours near noon, in wich there is a predominance of sky conditions III and IV. The monthly hourly frequency of sky condition I ranged from 46,91% of the photoperiod in January to 25.27% in August. And the frequency monthly daily ranged from nine days in January to three days in August. To the sky condition IV, the frequency monthly hourly ranged from 38.81% of the photoperiod in August to 18.17% im January. And the frequency monthly daily ranged from 17 days in August to three days in January.
