I am going to implement an existing aerobic program on obese adults with strength exercises. The course will provide the test protocol for the evaluation of the strength of certain muscle groups, but my health ideology tends to make me reject test with which you evaluate the loads supported, extrapolation of RM for various exercises to strength machines and so on, even if they are objectively more comparable in the literature. Qualitatively test as PPT or CS-PFP questionnaires on daily activities and more are better, but less comparable. Found that the most important thing is to stimulate an improvement in physical performance of these subjects in the best way to deal with daily activities and reduce the risk of chronic diseases, from the scientific point of view, however the question remains on how to investigate the possible assessments force. Do u think is better a more comprehensive approach, then more oriented to the improvement of the general conditions of the subject, more ethical but less objective or a more analytical approach and therefore more comparable in the literature, such as assessing the strength of the quadriceps by leg extensions?
