Held in 2008, the Rezende Futsal Cup Under-18 with the participation of six schools, five private and one state. Were performed in total, adding to the group stage, semifinal contest of 3rd and 4th places and final, ten matches, four of them in court size 26x13 and the other six matches on court size 30x17. The objective of this study was to quantify the relationship between the size of the court, the amount of goals, faults, cards, and for substitutions in the final outcome of matches. The Futsal, over the years, due to changing rules and also by the limited space of the court, has become a sport increasingly dynamic. With the change in size of one court to the other, we can clearly observe the variance in the final results, and with regard to the amount of substitutions, faults and cards. For the development of this research was used paper, pen and calculator, addition to overviews of the ten matches; data were collected, analyzed and discussed for the development of a complete content. Returned the following results: both average goals, faults and yellow cards were higher on the court of 26x13; the substitutions were in greater number on the court of 30x17. It was concluded that because of the averages goals, faults and yellow cards be larger in the on the court of 26x13 explained by the fact size even smaller than normal make the game even more dynamic and disputed, already the fact that the number of substitutions, have been higher on the court 30x17 explained by the fact that the bigger the game space the greater the physical demands the athlete. Key Words: Goals; Fouls; Cards; Substitutions.

Has developed this study aiming to quantify and analyze in terms of time a card (yellow and red), followed by football referees during the games of the Brazilian championship of professional football in 2008. Football is characterized as a physical activity in direct contact with the enemy in the field of play that requires efforts of high intensity and great physical wear. Over the years, the average distances covered by players during a soccer game rose considerably, with it, the football referees in addition to good technical knowledge, they must be good physical condition to monitor the development of the game. These new demands have brought sports to the presence of elements and neutral bodies and agencies to promote, international arbitrators established by the performance in terms of its function and control of violence. The flexible character and interpretation of the rules in their application generates discord on the issue. Data collection was conducted through the official summaries of games where the cards are reported and that time were applied to the athletes that are filed in the Brazilian Football Confederation (CBF). Key Words: Football; Violence; Football Referees; Cards.

The purpose of this study was to analyze the grades in goals resulted from offensive moves with possession of the ball and from counterattacks in one U-20 Futsal competition. Eighteen matches of Taça Paraná U-20 Futsal 2009 were observated by two people that got data (scout) from different teams. There were carried out 3.435 offensive moves with possession of the ball resulting in 1.067 kicks and 58 goals and 368 counterattacks resulting in 158 kicks and 26 goals. There is no doubts about the higher ocurrence of goals resulted from possession of the ball. Besides, the result of this study showed that counterattacks have a higher grade since one in 14,15 moves will result in a goal. Key Words: Futsal; possession of the ball; counterattack; goal.

Objective: This study shows a correlation between the Cooper Test (CT) and Yoyo Endurance Test L1 (YETL1) to predict the maximum volume of oxygen on the body mass index (VO2 max. Ml / kg / min.). The study looks for the most recommended test for football players under 15. Materials e methods: Eight football players (n = 8) participated in this study: they are male, with a mean age of 14.88 (±0.35) years, mean height 173.98 cm (±6.36) and mean weight of 72 kg (±5.39), apparently with good healthy. The athletes were submitted to two different tests procedures to predict VO2max: the YETL1 procedure and the CT procedure. The results were analyzed by parametric statistical tests of correlation (r) and compared the ratio between the groups. The study adopt an error margin of P<0.05, which is usually adopted in health studies. Results: Mean VO2 max. is 44.00 ml / kg /min. (±4.60) for TC test. On the other hand YETL1 test showed a mean of 56.91 ml/ kg/ min. (±3.41). The correlation is r= 0.71. The heart rate average is 157.13 (±20.14) beats per minute (bpm) for TC, and 181.88 (±7.85) bpm for YETL1. The correlation index for heart rate is r= -0.08. The average rate of TC/YETL1 is 0.86, and this result is considered relevant. Discussion: The correlation to VO2 max. r= 0.71 presented has a significant and relevant rate of 0.77, confirming the data. The correlation for Heart frequency is r= -0.08; it is mean no correlation between the tests. However, the rate of 0.86 is relevance for results. Conclusion: The values of VO2 max. shows correlation between the CT and YETL1, otherwise, the heart rate shows no correlation between the tests. In all tests, the results of Cooper were lower than YETL1, suggesting that, the most appropriate protocol for VO2 max. for under 15 footbal players is YETL1. Key Words: VO2 max, Cooper test, yoyo endurance test, athletes, amateur football and correlation.

Objective: we aimed to analyze the profile of the menstrual cycle in female soccer athletes with patterns of fat percentage suggested by the modern scientific literature. Materials and Methods: 28 elite athletes with fat percentage between 12 and 15% with monitoring and recording of the menstrual cycle for 03 months. Results: The results show that most of the athletes have irregular menstrual cycle (92.86%). Discussion: The results are consistent with the literature states that the woman is placed in competitive sport. Thus when we view the combination of results, we find that even with a fat percentage suggested in research, the athletes showed irregularities in their menstrual cycle. Conclusion: we conclude that the athletes with the fat between 12 and 15% in vigorous training and competitions for high performance has irregularities in the menstrual cycle. Thus, we must expand the studies in several other percentages of fat to check if the influence is directly related to the percentage of fat, training or a combination of these. Key Words: Menstrual cycle, Body Fat Percentage, Women and Sports Training.
