    Abstract: Female soccer has grown substantially in our country. Fifteen female soccer players aged 22.3 ± 6.2, weight 58.2 ± 8.3 kg and height 162.5 ± 61 cm were submitted to an evaluation of several parameters which are considered important to their physical capacity and athletic fitness. Moreover, we compared some functional rates in the literature showing the results of players from other countries with more practical experience in this game. The parameters and results were: Metabolic and cardiorespiratory during rest and during exercise: HR = 87 ± 8 bpm; SBP = 100.6 ± 4.5 mmHg; DBP = 62.6 ± 4.5 mmHg; HRmax. = 194 ± 7 bpm; Borg Scale = 19.5 ± 0.8; running velocity max. = 13.4 ± 0.9 km.h-1; VT1 = 8.5 km.h-1; VT2 = 11.2 km.h-1; VO2 peak = 47.3 ± 4.5 mlO2.kg-1.min-1; Cybex: right isokinetic torque of knee extensor at 60º S-1 = 198.5 ± 44.1 Nm; in flexors = 116.5 ± 18.8 Nm; left = 203.6 ± 38.1 Nm; 116.5 ± 18.8 Nm; Wingate: peak power corrected by weight = 9.5 ± 0.9 w.kg-1; mean power = 7.5 ± 0.5 w.kg-1; fatigue rate = 56.7 ± 7.3%; body fat % = 17.4 ± 2.3%; Ophthalmologic evaluation: long-range visual acuity in the right and left eye = 97.5 ± 5.8%, respectively; intraocular pressure in the right and left eye = 13.7 ± 2.7 and 13.1 ± 2.4 mmHg, respectively. The variable which could be compared to international female soccer results pointed our athletes had equivalent rates and rather superior, in some cases. Nevertheless, because of lack of information, the most adequate rates for the practice of this modality by women could not be quantified. In the author's opinion, a greater volume of investigation is needed focusing various female soccer features.

    Abstract: RESUMO CONTEXTO E OBJETIVO: O objetivo do presente estudo é avaliar modelos matemáticos de pós-análise do limiar de lactato em grupos de corredores de longa distância muito ou pouco treinados. TIPO DE ESTUDO E LOCAL: Estudo laboratorial experimental. Hospital Público Universitário Terciário. MÉTODO: Vinte e sete corredores homens foram divididos em: pouco treinados (frequência 〈 4 vezes por semana, 〈 6 meses, velocidade ≥ 5,0 minutos/km) e muito treinados (frequência ≥ 4 vezes por semana, ≥ 6 meses, velocidade 〈 5,0 minutos/km). Os participantes foram submetidos a protocolo de esteira escalonado (1% inclinação) = 1 km/h por fase (4 minutos). Ao fim de cada estágio, análise da "impressão digital" metabolômica foi realizada. O limiar do lactato (i.e. velocidade em que o lactato sanguíneo aumenta exponencialmente) foi medido utilizando-se três métodos: aumento de 1 mmol/l da concentração, concentração absoluta de 4 mmol e método semi-log. ANOVA foi utilizada para comparar os diferentes limiares de lactato e grupos. RESULTADO: Atletas muito treinados apresentaram limiares de lactato maiores que os corredores pouco treinados, independentemente do método de cálculo utilizado. Comparando todos os corredores juntos, as análises de aumento de 1 mmol/l e semi-log não foram diferentes, enquanto a concentração absoluta de 4 mmol/l foi significativamente mais baixa que as dos dois outros métodos. Essas mesmas tendências foram observadas ao se compararem os métodos de limiar de lactato no grupo menos treinado. Entretanto, a análise absoluta de 4 mmol/l foi menor do que a do aumento de 1 mmol/l no grupo muito treinado. CONCLUSÃO: O método concentração absoluta de 4 mmol não mostrou mensurações comparáveis de limiar do lactato quando comparado com os protocolos aumento de 1 mmol/l e semi-log nos atletas pouco treinados.

    Abstract: O objetivo desse estudo foi verificar o envolvimento do metabolismo anaeróbio lático por meio de medidas de lactato sanguíneo em futebolistas profissionais imediatamente após o término do primeiro e do segundo tempos, em partidas de futebol. Foram avaliados 26 jogadores, todos do sexo masculino e pertencentes ao Departamento de Futebol Profissional da Associação Portuguesa de Desportos de São Paulo. O grupo foi composto por 4 laterais, 13 meio-campistas e 9 atacantes. A idade variou de 18 a 33 anos, o peso de 56,5 kg a 78,5 kg e a estatura de 164 cm a 185 cm. A escolha dos futebolistas durante os procedimentos foi aleatória. Foi utilizado um analisador de lactato portátil (modelo Accusport®, Boehringer Mannheim®, GER). Os seguintes resultados foram verificados: a média de lactato em todos os jogadores verificados ao final do primeiro e do segundo tempos das partidas analisadas foi de 7,1 mM ± 0,6 mM e 5,7 mM ± 1,3 mM (p 〈 0,05). Quando divididos por posição, os laterais apresentaram respectivamente: 6,9 mM ± 2,9 mM e 4,7 mM ± 3,0 mM; os meiocampistas: 6,4 mM ± 1,8 mM e 5,6 mM ± 1,2 mM e os atacantes: 7,7 mM ± 1,8 mM e 7,2 ± 2,1 mM. Quando comparamos a produção de lactato pelas posições, somente houve diferença estatística significante (p 〈 0,05) no segundo tempo entre os atacantes 7,2 mM ± 2,1 mM e os meio-campistas 5,6 mM ± 1,2 mM, respectivamente. Conclusão: Fatores subjetivos como grau de movimentação, recuperação rápida e disposição constante na partida, relacionados a fatores primários como atividade glicolítica reduzida e a diminuição da concentração de glicogênio muscular, motivados por pouco treinamento anaeróbio lático específico e/ou uma dieta deficiente, são evidências que podem explicar, em parte, porque o lactato sanguíneo no segundo tempo tem sido freqüentemente mais baixo quando comparado ao término do primeiro tempo em uma partida de futebol.

    Abstract: The aim of this study was to make an approach on the importance of the anaerobic threshold (AT) and the peak oxygen uptake in soccer players, and compare the results found in players to those existing in the specialized literature. An evaluation was made in 18 professional soccer players aged 24 ± 4; weight 72.5 ± 5.9 kg; height 176.5 ± 7.0 cm, and body surface 1.91 ± 0.15 m². Every athlete was evaluated after a 2 month training period. The soccer players were submitted to a maximum exercise test on treadmill, using incremental continuous protocol. The heart rate (HR) was recorded by means of an electrocardiograph (HeartWare) with 12 simultaneous leads and the arterial blood pressure (BP) by auscultation method. The pulmonary ventilation (V E), the oxygen uptake (VO2), the carbon dioxide production (VCO2) and the respiratory exchange rate (RER) were evaluated by means of the breath-by-breath spirometric computerized method (MedGraphics Corporation-MGC). The following results were verified in the AT: HR = 173.6 ± 8.6 bpm; VO2 = 55.78 ± 5.93 mlO2.kg-1.min-1; running velocity = 14.6 ± 1.0 km.h-1; maximum exercise: HR = 189.5 ± 11.4 bpm; V E = 134.1 ± 15.9 L.min-1; VO2 peak = 63.75 ± 4.93 mlO2.kg-1.min-1; maximum velocity = 17.8 ± 1.0 km.h-1; Borg scale = 18.3 ± 1.3 points. In conclusion, the results, when compared to those of specialized literature, proved the rate of AT and VO2 peak to be similar and even superior to several results published about such two variables in professional soccer players. Considering, however, the players' position, there is no definite consensus on the most adequate AT rates and VO2 peak in soccer players, but only suggestions.

    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.

    Abstract: The purpose of this investigation was to study the effect of specific training on cardiorespiratory and metabolic responses in sixteen male professional soccer players, aged 24.2 ± 3.6 years old. They were evaluated before and after fifteen weeks of specific training. All subjects were submitted to an exercise test on treadmill, using Ellestad's protocol. The heart rate was recorded by means of ECG, and the arterial blood pressure by auscultatory measurement. Oxygen uptake, carbon dioxide production, and pulmonary ventilation were measured by a Measurement Metabolic Cart (Beckman). Maximum anaerobic capacity was evaluated by blood lactate concentration, using an automated analyzer. Specific training did not modify the maximum heart rate (192 ± 8 vs. 186 ± 6 beats.min_1) and the maximum systolic blood pressure (196 ± 10 vs. 198 ± 8 mmHg). Maximum respiratory ventilation was significantly increased by specific training (129 ± 19 vs. 140 ± 16 L.min_1), whereas maximum aerobic capacity was not significantly increased (50 ± 6 vs. 53 ± 5 ml.kg._1 min_1 ofO2). On the other hand, maximum aerobic capacity improved significantly (8.3 ± 0.2 vs. 9.8 ± 2.4 mmol.L_1). Conclusion: 1) the specific training used in the present study did not modify heart rate and arterial blood pressure responses at rest and during maximum exercises; 2) improvement of maximum pulmonary ventilation and higher lactic acid concentrations during maximum exercise showed that the exercise training used in this study was predominantly characterized by intense exercise, and 3) specific training was not an adequate stimulus to improve maximum aerobic capacity of the soccer players.

    Abstract: The main goal of this investigation was to analyze cardiorespiratory features and metabolic alterations caused by specific dance training in a group of 16 professional classical ballet dancers, 8 female and 8 male, mean age 18.2 ± 3.8 and 26.2 ± 4.5, respectively. All subjects were submitted to maximum exercise test on the treadmill using Bruce's protocol. Cardiorespiratory and metabolic responses were analyzed by a Beckman Metabolic Measurement Cart computerized system. The following results were found for the male ballet dancers group vs. the male control group: VO2 max. (46 ± 4 vs. 43 ± 6 ml.kg-1.min-1 of O2); HR max. (194 ± 12 vs. 202 ± 11 beats.min-1); V E max. (112 ± 16 vs. 123 ± 18 L.min-1); VO2 at AT (35 ± 4 vs. 26 ± 4 ml.kg-1.min-1 of O2 [p 〈 0.01]); HR at AT (169 ± 18 vs. 163 ± 15 beats.min-1). Female ballet dancers group vs. female control group: VO2 max. (39 ± 6 vs. 35 ± 6 ml.kg-1.min-1 of O2); HR max. (197 ± 10 vs. 201 ± 6 beats.min-1); V E max. (72 ± 9 vs. 81 ± 6 L.min-1); VO2 at AT (26 ± 4 vs. 27 ± 4 ml.kg-1.min-1 of O2); HR at AT (164 ± 10 vs. 176 ± 17 beats.min-1). Conclusion: 1) the specific ballet dance training routine does not seem to generate an adequate stimulus to improve cardiorespiratory and metabolic ballet dancers aptitude, and 2) the authors suggest an additional physical training programs to improve ballet dancers physical conditioning.

    Abstract: The purpose of this investigation was to caracterize the relationship between the level of physical fitness, performance and metabolic needs in soccer players during a real match-play. Six professional soccer players aged 20.8 ± 2.6 years old (17-25), weight 70.4 ± 7.5 kg (63-81.3) and height 173.3 ± 9.7 cm (166-188) were submitted to a fitness test which was performed in the soccer field. The players were assessed by a video-camera, in the field, during the match-play with lactate evaluation. The alactic metabolic pathway was evaluated by means of five 30 m sprints, in maximum velocity and one minute of passive pause between each sprint. The lactic acid concentrations were assessed at one, three and five minutes after the five sprints had been finished. To detect anaerobic threshold (AT), three 1,200 m races were performed at an intensity of 80, 85 and 90% from de maximum speed to that distance, with 5 minutes intervals between each running. The soccer players underwent individual film recording by a video-camera, during the match-play and the lactic acid concentrations were assessed before, during the interval and at the end of the match, to analyze the metabolic and energetics expenditure. The following results were verified: 1) the AT at running, relationed to 4 mmol.L_1 lactic acid concentration, was found at 268 ± 28 m.min_1 or 16.1 ± 1.6 km.h_1; 2) the average speed and the maximum lactate concentration at 30m sprint were 6.9 ± 0.2 to 4.5 ± 1.0 mmol.L_1, respectively; 3) the total performed distance was 10,392 ± 849 m, 5,446 ± 550 m was found in the first half of the match and 4,945 ± 366 m was found in the second half of the match; 4) the average values found in assessing blood lactate concentrations were 1.58 ± 0.37; 4.5 ± 0.42 and 3.46 ± 1.54 mmol.L_1; before, during the first to the second interval and at the end of the match, respectively; 5) the total average distance approached at the end of the matches by midfield players (10,910 ± 121 m) was slightly greater than the one reached by the forward players (10,377 ± 224 m) and defenders (9,889 ± 102 m), nevertheless, it was not significant. There was a negative correlation (r =- 0.84; p 〈 0.05) among the AT (268 ± 28 m.min_1 or 16.1 ± 1.6 km.h_1) and blood lactate concentration (4.5 ± 0.42 mmol.L_1) in the first half of the match-play. Thus, the results suggest that the aerobic capacity is an important determinant, which leads the soccer players to cover the long distance runnings in the matches, and be able to recover earlier from the high intensity effort with a lower development of blood lactic acid concentrations in the whole match-play.

    Abstract: O objetivo deste trabalho foi verificar, de modo amplo, o comportamento de variáveis importantes para a saúde preventiva e o desempenho atlético, em jogadores de futebol profissional. Além disso, o estudo tece comentários, através de longa revisão bibliográfica, sobre os resultados de nossos atletas e os observados na literatura especializada, nessa modalidade esportiva. Os futebolistas foram submetidos a uma bateria de testes clínicos, laboratoriais e de aptidão cardiorespiratória, metabólica e muscular, pré-participação ao Campeonato Brasileiro de Futebol de 1996, que constou das seguintes variáveis: consumo de oxigênio, limiar anaeróbio ventilatório, eletrocardiografia em repouso e no exercício, potência muscular ( wingate), flexibilidade, hemograma, reações sorológicas para doença de Chagas, protoparasitológico, glicose, uréia, creatinina, colesterol total e frações, hormônios, eletrólitos, minerais, composição corporal, avaliação fisioterápica, odontológica e nutricional. Os resultados obtidos indicaram que o emprego de uma avaliação multifatorial, em atletas de alto rendimento, é um procedimento importante para verificar se o nível de aptidão física está adequado e/ou detectar possíveis deficiências, que possam interferir no desempenho atlético dos futebolistas, durante os treinamentos e jogos.
