RESUMO
This study compared the exercise intensity of four specific soccer training sessions (friendly and training match, tactical and technical workouts). Ten professional soccer players (24.2 ± 3.7 years, 177.9 ± 7.3 cm, 63.2 ± 4.6 mLO2kg-1min-l) were recruited. A treadmill progressive interval test was performed to determine the players' VO2max, maximal heart rate (HRmax), HR-VO2 curve, and the heart rate corresponding to blood lactate concentrations of 2 and 4 mmol/L. The heart rate during the training sessions was used to estimate the exercise intensity and to classify them into intensity zones (low-intensity: <2 mmol/L; moderate-intensity: between 2 and 4 mmol/L; high-intensity: >4 mmol/L). Exercise intensities were different among training sessions (friendly match: 86.0 ± 5.1% HRmax; training match: 81.2 ± 4.1% HRmax; tactical workout: 70.4 ± 5.3% HRmax; technical workout: 62.1 ± 3.6% HRmax). The friendly match presented the highest percentage of time performed in the high-intensity zone.
Este estudo comparou a intensidade de quatro treinamentos específicos de futebol (jogo treino, amistoso, treinos técnicos e táticos). Dez jogadores de futebol profissional foram recrutados (24,2 ± 3,7 anos, 177,9 ± 7,3 cm, 63,2 ± 4,6 mLO2kg-1min-l). Um teste progressivo intervalado em esteira foi realizado para determinar o VO2max, frequência cardíaca máxima (FCmax), curva FC-VO2, e frequência cardíaca correspondente às concentrações de lactato de 2 e 4 mmol/L. A frequência cardíaca dos treinos foi usada para estimar a intensidade do exercício e classificá-los em zonas de intensidade (baixa, <2 mmol/L; moderada: entre 2 e 4 mmol/L; alta: >4 mmol/L). As intensidades das sessões de treinamento foram diferentes (jogo amistoso: 86,0 ± 5,1% FCmax; jogo treino: 81,2 ± 4,1 % FCmax; treino tático: 70,4 ± 5,3% FCmax; treino técnico: 62,1 ± 3,6% FCmax). O jogo amistoso apresentou porcentagem mais alta de tempo realizado na zona de intensidade alta.

Diez jugadores de futbol profesional fueron reclutados (24,2 ± 3,7 años, 177,9 ± 7,3 cm, 63,2 ± 4,6 mLO2kg-1min-l). Un examen con intervalos progresivos en la caminadora fue realizado para determinar: VO2max, FCmax, curva FC-VO2 y frecuencia cardiaca correspondiente a las concentraciones de lactato de 2 y 4 mml/L. La frecuencia cardiaca de los entrenamientos fue usada para estimar la intensidad del ejercicio y clasificar zonas de intensidad (baja <2 mmol/L; moderada >2 y <4 mmol/L; alta >4 mmol/L). Las intensidades de las sesiones de entrenamiento fueron diferentes (juego amistoso: 86,0 ± 5,1% FCmax; entrenamiento 81,2 ± 4,1 % FCmax; entrenamiento táctico 70,4 ± 5,3% FCmax; entrenamiento técnico 62,1 ± 3,6% FCmax). El juego amistoso presentó porcentaje más alto de tiempo realizado en la zona de intensidad alta.

The purpose of this study was to assess the intensity of official Futsal matches, expressed in different ways. Fourteen male professional Futsal players from a First Division Brazilian team volunteered to participate in this study. Maximal oxygen uptake (VO(2)max) and the heart hate (HR) and oxygen uptake (VO(2)) correlation were determined for each player. The match intensity was estimated from the players' average HR measured during 13 National Futsal League matches. The HR measurements were obtained while the players were in the court but the values recorded while the players were sitting on the bench were not considered. In addition, these HR values were used to estimate the intensity of the effort expressed as a percentage of the maximal HR (% HRmax), percentage of VO(2)max (% VO(2)max), kilocalories per minute (kcal·min(-1)), and total caloric expenditure. The mean intensity of the matches was 86.4 ± 3.8% HRmax, 79.2 ± 9.0% VO(2)max, 18.0 ± 2.2 kcal·min(-1), and 313 ± 9.3 kcal. It was concluded that official Futsal matches have high intensity when expressed in the different ways used in this study. The information provided by this research can be used for planning the athletes' workouts, diets, and resting periods.
