Motivation in Self-Determination Theory (SDT) suggests that one may be motivated in different levels. In this study these differences are explored through comparisons of the motivation general levels, taking into account the "gender and age groups" variables. A sample of 635 participants from both gender and ages between 18 and 55 years old answered the Motivation to the Regular Practice of Physical and Sports Activity Inventory (IMPRAFE-126). Results point significant difference (F(2, 632) = 7,214; p = 0,001) only when controlled the age group. Differences were interpreted as recommended by SDT and related to the states and tasks of the development.
