The American Academy of Orthopaedic defines attitude as the state of balance between muscles and bones with protective capacity of other structures of the human body trauma, either in standing, sitting or lying (Braccialli and VILARTA, 2000). Taking this into consideration, the existence of muscle imbalance, causes changes in the individual posture, and can thus cause other problems if not promptly diagnosed or treated properly.
In fact, most postural problems can be attributed to the form of organization of the training routines of sports practices where there is too much, the overload on the muscle groups most used for such activity, thus disregarding their action for the maintenance of posture (RAGONESE, 1987).
In this context, as important as the development of specific qualities for high performance, should be the concern with posture and muscle balance, as they influence the athlete’s performance and can minimize the incidence of sports injuries (RAMOS e FREITAS, 1996). Care in sports practice so that there is muscle imbalance goes from the larger muscle groups to minors.
The study by Kwon et al. (2009), which evaluated strength of extensor and flexor muscles of the toes, had concluded that the muscle imbalance between these, affects the deformity of the fingers, causing the “hammer toe” and inverse correlation amplitude with respect to dorsiflexion and eversion of the ankle, so as to deformity increases, the smaller the range of ankle motion, making it also a problem for the individual performance.
Therefore, in view of the performance and also the health of the practitioner of physical exercises, care in prescribing the training routines is necessary.
