Composición corpora de futbolistas profesionales en función de la edad cronológica

Abstract

RESUMOEstudar a composição corporal de jogadores de futebol em relação a idade cronológica e anos de treinamento são importantes indicadores na avaliação, diagnóstico, prescrição e controle do treinamento. Objetivo: Analisar a composição corporal de jogadores profissionais de futebol em relação à idade cronológica. Métodos: A amostra foi composta por 95 jogadores profissionais que atuavam na primeira divisão do campeonato do futebol Peruano. Foram avaliadas as variáveis: Idade cronológica, anos de treinamento, peso, estatura, 6 dobras cutâneas, % de gordura, massa gorda (MG) e massa livre de gordura (MLG ). A idade cronológica foi classificada em 5 grupos de idade (18-21, 22-25, 26-29, 30-33 e 34-37 anos). Utilizou-se estatística descritiva e ANOVA (Tukey) par as comparações entre grupos. Resultados: Não houve diferença na estatura, percentual de gordura e massa gorda (p> 0,05). Houve aumentos significativos no peso corporal (5,4 kg) e massa magra (4,7 kg) em relação à idade cronológica. Os aumentos significativos de ambas as variáveissão atingidos no rango dos 26-29 anos com uma média de 12,6±2,2 anos de treinamento. Conclusões: A massa corporal total e massa magra aumentaram significativamente em relação a idade cronológica, observando-se valores mais elevados em idades mais avançadas. Estes resultados sugerem que nos programas de treinamento, os jogadores de futebol devem ser classificados por grupos de idade. ABSTRACTAnalysis of body composition of professionals based on chronological age and years of training, soccer is important in the evaluation, diagnosis, prescription and monitoring of training, allowing you to make proper planning of the conditions physical, and consequently achieve specific adaptations to improve athletic performance. Objective: To analyze the body composition of professional footballers based on chronological age and years of training. Methods: The sample consisted of 95 professional players from League Perú. Chronological age, years of training, weight, height, 6 skinfolds , % fat, fat mass (MG) and fat-free mass (FFM) was assessed. Age and years of training were classified into 5 ranks. Descriptive statistics were performed and two-way ANOVA and Tukey were applied, with a significance level of 5%. Results: There was significant increase in body weight (5.4 kg) and FFM (4.7 kg) as a function of chronological age. As the years of training the increased weight (4.41kg) and MLG (3.99 kg). Significant increases in body weight and MLG are reached in the age range of 26-29 years of age and averaged 12.6 ± 2.2 years of training. Conclusions: Total body mass and FFM increase with chronological age and years of training. These results suggest classifying players by age and years of training with the intention of assessing and designing specific training programs.

Trimestral Change in Height, Weight, Body Fat and muscle Mass in Young Football Players of Different Categories

“…Other authors who have related CC to injuries suffered by football players have shown that the ratio of fat mass to bone mass of a body segment correlates inversely with the risk of injury [8][9][10][11][12][13]. In this sense, we can indicate that low fat-free mass (FFM) values are associated with low levels of strength, which leads to sports injuries [14]. Similarly, there is a relationship between increased BMI and low %FMG values with an increased risk of injury for young football players [15].…”

Quarterly Percentual Change in Height, Weight, Body Fat and Muscle Mass in Young Football Players of Different Categories

“…Other authors who have related BC to injuries suffered by football players have shown that the ratio of fat mass to bone mass of a body segment correlates inversely with the risk of injury [9,14]. In this sense, it can be suggested that low fat-free mass values are associated with low levels of strength, which leads to sports injuries [15]. Similarly, there is a relationship between increased BMI and low BFP values with an increased risk of injury for young football players [16].…”
