Muscle Power (often expressed in terms of explosive strength or explosive force) is required in most sports activities that involve intense and rapid contractions. Purpose: Identifying the dif-ferences and their significance, between the muscle strength values for the female students of the Faculty of Physical Education and Sports, according to their classification by BMI levels. Materi-al and method: 77 female students of the Faculty of Physical Education and Sport from Galati were evaluated through 6 upper body muscle power tests (30s Plyometric Push-Ups, Shot put, Medicine ball chest throw, Overhead Medicine Ball Throw-forward, Overhead, Medicine Ball Throw-backward, Overhand ball throw) and 7 lower body muscle power tests (Speed Test 10m, Standing Long Jump Test, Vertical Jump Test, 3-Hop Test, 30s Continuous vertical jumps, 30s Lateral double leg hop test, The multiple 5 bounds test). The groups were divided according to BMI levels (underweight 11 cases, normal weight 53 cases and overweight 13 cases). The non-parametric Kruskal–Wallis and Mann-Whitney U tests were used to assess the differences be-tween groups. Results: Arithmetic average values indicate the superiority of underweight and normal-weight women for lower-body strength and overweight and normal-weight women for upper-body strength, especially for heavy objects throw variants. However, performance differ-ences (assessed by ranks) are in most cases insignificant (Z values correspond to thresholds P>0.05). The only exceptions with significant differences (P<0.05) are for Overhead Medicine Ball Throw-forward (with the superiority of the overweight over the underweight) and Shot put - track and field (with the superiority of the overweight over the underweight). Conclusion: The constant involvement of female students in curricular and sports physical activities mitigates the differences between the muscle power of the 3 BMI categories. However, the small numerical composition - for the underweight and overweight groups - does not allow the generalization of the results, as studies on larger samples are needed and have common concerns related to the specifics of the sports practiced.
