RESUMO
Fundamentação: Os profissionais que trabalham com musculação tem questionado as formas de avaliação da força dinâmica para a prescrição de exercícios. Objetivo: desenvolver e validar uma equação de predição da Carga de Trabalho para o Treinamento com Pesos (CTTP) para o exercício de supino horizontal com pesos livres, em praticantes de musculação recreacional de nível intermediário. Materiais e Métodos: amostra composta de 60 (sessenta) praticantes de musculação recreacional. Para avaliação antropométrica e da composição corporal foram utilizados: a massa corporal, estatura e a estimativa da massa corporal magra, da massa gorda e do percentual de gordura. Para a força máxima de membros superiores foi utilizado o teste de 1RM no exercício de supino horizontal, utilizando pesos livres. Resultados: os resultados foram: Uma Repetição Máxima (1RM) (75,5±12,7Kg); idade (23±3,15anos); %gordura (8,3±3,0%); massa corporal (71,1±13,0Kg); estatura (172,0±8,4m); massa corporal magra (62,8±10,6Kg) e massa gorda (6,2±3,5Kg). Discussão e Conclusão: foi possível desenvolver e validar uma CTTP para o exercício de supino reto, com um Erro Padrão de Estimativa (EPE) de 3,378kg) e R²-0,98.
Palavras chave: Validação, equação de predição e Carga de trabalho com pesos.

Development and validation of equation of prediction the load of work for training with weights in the bench press exercises, for men of intermediate level.
ABSTRACT
Back Ground: The professionals who work with muscle exercise have questioned the forms of evaluation of the dynamic force for exercise prescription purposes. Objective: to develop and to validate an equation for prediction of the load during weight training in the exercise of horizontal bench press with free weights. Materials and Methods: the sample comprised 60 (sixty) subjects engaged in recreational muscle exercise programs. For anthropometric evaluation and body composition the following measures were used: body mass, stature, estimated lean body mass, estimate body fat mass and the percentage of fat. For the maximum force of upper members the Repetition Maximum test (1RM) in the exercise of horizontal bench press was used. Results: the main results were: 1RM (75,5±12,7Kg); age (23±3,15years); %fat (8,3±3,0%); body mass (71,1±13,0Kg); stature (172,0±8,4m); lean body mass (62,8±10,6Kg) and fat body mass (6,2±3,5Kg). Discussion: it was possible to develop and to validate an equation of prediction of the load of work for weight training in the exercise of horizontal bench press, with a Standard Error of Estimation (SEE) of 3,378kg), and R²=0,98.
Key words: validation; equation of prediction; load of work for training with weights
