LIMA, Michel Leonardo Ferreira et al. 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. Motri. [online]. 2008, vol.4, n.1, pp.39-46. ISSN 1646-107X.

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.

Keywords : validation; equation of prediction; load of work for training with weights.
