Resumo: | The purpose of the present study was to analyze the energy expenditure and heart rate (HR), expressed as mean and maximal heart rate (HRmax), along matches of an official soccer competition. Methods: Eighteen under-20 year old (U-20) soccer players from a first-division Brazilian soccer team were evaluated during 15 matches. The relationship between HR and oxygen uptake (HR/VO2 relationship) was established, and a linear regression equation was developed for each individual player participating in the study. This equation was then used to determine the oxygen uptake and the corresponding energy expenditure based on the HR values measured during the games. The HR was recorded at 5-second intervals, which were clustered in phases of 15 minutes (0-15 min, 15-30 min e 30-45 min) for each half time (first half [FH] and second half [SH]). Results: The players’ oxygen uptake was 308.3 ± 11.9 LO2/game and the energy expenditure was 17.3±1.3 Kcal.min-1 and 1,542.9±125.1 Kcal/game. The results showed that there were significant differences between the HR and HRmax identified in the first half (FH 15-30 min) compared to the second half (SH 0-15 min and SH 30-45 min), and at FH 30-45 min compared to SH 0-15 min (p<0.05). Conclusions: We concluded that soccer should be considered as an extremely arduous activity for U-20 players due to the high energy expenditure during the matches of an official championship. We also concluded that, during soccer games with young players, FH 15-30 min could be considered the most intense phase, because the highest values of HR and HRmax usually occur at this phase. |

O objetivo do presente estudo foi a análise do gasto energético e da frequência cardíaca (HR), expressa pela média e pela frequência cardíaca máxima (FCmax), durante jogos de uma competição oficial de futebol. Foram avaliados, durante 15 jogos, dezoito jogadores de futebol da categoria abaixo de 20 anos de idade (Sub-20) de um time da primeira divisão de futebol brasileira. A relação entre FC e consumo de oxigênio (relação FC/VO2) foi estabelecida, e uma equação de regressão linear foi desenvolvida para cada jogador. Essa equação foi utilizada para determinar o consumo de oxigênio e o gasto energético correspondente a partir dos valores de FC medidos durante os jogos. O registro da FC ocorreu em intervalos de 5 segundos, agrupados em fases de 15 minutos (0-15 min, 15-30 min e 30-45 min) em cada tempo de jogo [primeiro tempo (PT) e segundo tempo (ST)]. O consumo de oxigênio dos jogadores foi de 308,3 ± 11,9 LO2/jogo e o gasto energético foi de 17,3 ± 1,3 Kcal.min-1 e 1.542,9 ± 125,1 Kcal/jogo. Os resultados mostraram que houve diferenças significativas entre a FC e a FCmax observadas no primeiro tempo (PT 15-30 min) em relação ao segundo tempo (ST 0-15min e ST 30-45min), e entre PT 30-45 min em comparação com ST 0-15 min (p<0,05). Concluímos que o futebol deve ser considerado como uma atividade extremamente árdua para jogadores Sub-20, devido aos alto gasto energético durante as partidas de um campeonato oficial. Conclui-se também que, durante jogos de futebol com jogadores jovens, a PT 15-30min poderia ser considerada a fase mais intensa do jogo, porque os maiores valores de FC e FCmax usualmente ocorrem nessa fase.
