    Abstract: The purpose of this investigation was to verify the impact of seven ventilatory time intervals on the maximum oxygen uptake (VO2 max) in professional soccer players. Eighteen male soccer players aged 24.4 ± 4 (18-31), weight 72.5 ± 5.9 kg (62-83) and height 176.5 ± 7 cm (164-188) were submitted to a maximum exercise test on treadmill, using the continuous protocol. The heart rate response was recorded by means of computerized ECG with 12 leads, simultaneously. The respiratory exchange ratio, carbon dioxide production, oxygen uptake and pulmonary ventilation were calculated by means of the spirometric computerized system. The results of this study demonstrated that there was significant variability (p 〈 0.05) in VO2 max only when it was compared instantaneously and by breath-by-breath response, in relation to other intervals analyzed (10, 20, 30, 40, 50 and 60 seconds, respectively). In conclusion, the authors observed that VO2 max increases were proportional to those found in the ventilatory sample intervals during the progressive intensity exercise. However, the higher time interval underestimated its increase. Thus, the authors suggest that the investigator should utilize mean intervals in a range between 10 and 60 seconds, since no significant statistic difference was verified among these intervals.

    Abstract: The aim of this study was to verify, through a food questionnaire covering a 24-hour recollection range, the adequacy of the daily caloric intake of macronutrients in 19 soccer players whose mean age was 18.6 ± 1.1 (16-20). All athletes belonged to the Amateur Soccer Department of Associação Portuguesa de Desportos in São Paulo. The soccer players were submitted to a food inquiry by means of personalized interviews. The ideal weight of the athletes was calculated by the mean body mass index (BMI) = 22.5 kg.m² multiplied by the stature in square meters. The basal metabolic rate was then calculated, the FAO/WHO/UN chart having been used. After that, by anamnesis carried out at the sector of athletic preparation, the volume of physical activity was quantified, which made it possible to determine the minimum, mena and maximum caloric value suitable for athletes. In addition, all soccer players were submitted to laboratory tests. By calculating the daily caloric needs according to the training, the following result and parameters were verified: minimum = 3,298 ± 177 kcal.day-1; mean = 3,689 ± 207 kcal.day-1 and maximum = 3,991 ± 225 kcal.day-1. The mean caloric consumption reached by the players used to be 2,584 ± 421 kcal.day-1. When a comparison was made between the mean intake they consumed with the minimal, mean and maximal values necessary, the percentage of caloric deficiency which they presented - 22%, 30% and 35%, respectively - was highly significant (p 〈 0.05). The laboratory tests revealed in one of the athletes the presence of anemia with 11.1% of Hb and 35% of hematocrit. The results of this study allow to conclude that both nutritional education intended to correct food behavior disorders, and severe control of the caloric needs, constitute procedures of prime importance for an adequate diet of soccer players.

    Abstract: The main purpose of this study was to verify the most frequent dental alterations found in soccer players. In a survey carried out by the dentistry department of this Association, the case histories of 400 soccer players were evaluated over a period of 6 years. The players _ 353 amateurs and 47 professionals _ aged 16.5 ± 2.1 (ranging from 9 to 20) and 24.7 ± 3.6 (ranging from 21 to 34), respectively, were all male members of the team of athletes in the soccer department. The tools used during the procedures were clinical mirror and explorer no. 5 (Duflex) in a model office (MLX Plus-Funk Trademark). The occlusion radiographs were obtained with Kodak films in the X-ray equipment (Spectro 11 model-Dabi Atlante Trademark). These were the alterations and results found in the amateur soccer players: 199 cases of tartarectomy (56%), 283 of caries (71%), 61 of gingivitis (17%), 51 of endodontics (14%), 33 of abscesses (9%), 21 of fistulas (6%) and 10 of aphthae (3%). In the orthodontic cases, the following alterations were found: diastema in 12 athletes (3.5%), crowded teeth in 35 (10%), heterotopic in 36 (10.2%), and impacted in 14 (1%). Seventy-eight extractions (22%), 41 fillings (11.5%) and 72 tooth replacements (20%) were carried out, while prophylactic measures covered 148 cases (42%). The professional soccer players presented the following results: 17 cases of tartarectomy (36%), 32 of caries (68%), 14 of gingivitis (30%), 11 of endodontics (23%), 6 of pulpitis (13%), absence of abscesses, 2 of fistulas and aphthae (4%), respectively. Six cases of orthodontics were verified, subdivided into 3 crowded and heterotopic teeth (6%), respectively. There were 78 extractions (51%), 6 fillings (13%), and 23 replacements of teeth (49%). Conclusion: results verified in this investigation have shown the importance of dentistry for both preventive and/or corrective measures. It is also important to stress that an inadequate teething process may cause gastrointestinal alterations and even musculoskeletal changes, thus making it difficult for athletes to participate in training and contests.

    Abstract: The main purpose of this study was to show the importance of functional evaluation as a procedure used in the physiological control of pre-season physical training for professional soccer players. In a preliminary round aiming at the 1999 São Paulo soccer championship, 23 soccer players belonging to the Departament of Professional Soccer of Associação Portuguesa de Desportos were evaluated and then assembled in Aguas de Lindoia, a resort in São Paulo State, for a 16-day period. All of them were submitted a battery of tests comprising cardiorespiratory, metabolic, odontological, and lower limb isokinetic evaluation, as well as body fat and anaerobic power percentage by the Wingate test and field tests. These were the results and parameters evaluated: in the ventilatory threshold, 2 (VT2): VO2 = 49.09 ± 4.83 ml.kg-1.min-1;%VO2 = 82.7 ± 5.8; running speed = 12.8 ± 0.9 km.h-1; HR = 174 ± 9 bpm; in maximum exercise: V E BTPS = 137.3 ± 11.3 L.min-1; running speed = 17.6 ± 0.7 km.h-1; HR = 191 ± 8 bpm; VO2 peak = 59.28 ± 3.52 ml.kg-1.min-1; lactic acid = 10.5 ± 1.5 mM. Wingate test: peak power = 13.5 ± 1.1 w.kg-1; mean power = 10.1 ± 0.6 w.kg-1; fatigue index = 53.0 ± 7.7%; isokinetic test: angular speed at 60°S-1 right leg extension and flexion = 298 ± 72 and 198 ± 44 Nm, respectively; at 300° S-1 extension and flexion = 137 ± 32 and 121 ± 26 Nm, respctively. Angular speed at 60°S-1 left leg extension and flexion = 272 ± 62 and 185 ± 45 Nm, respectively; at 300° S-1 extension and flexion 138 ± 28 and 122 ± 27 Nm, respectively. The intensity of aerobic and anaerobic training was controlled in the field by measuring lactic acid. To this end, the authors used a portable measuring device. The body-building training was carried out at a 60% maximum charge for each exercise. The limber-up and swimming-pool exercises were exhaustively carried out by the soccer players. Each training session (morning and afternoon) lasted 120 minutes on average. Therefore, considering the short time designed for this phase of preparation, the importance of a multidisciplinary functional evaluation is even more justifiable, for, according to the results, it allows one to detect and correct possible deficiencies with an objectively-oriented soccer player training.
