Background and Study Aim. Explosive strength/muscular strength is demanded at the level of different body segments and regions in most sports. The purpose of the research: is to identify the differences in the manifestation of explosive force between groups of underweight, normal weight and overweight university students; to determine the associations between the anthropometric parameters and the value of the results in the applied tests. Material and Methods. The investigated group consists of 147 students (men) of the Faculty of Physical Education and Sport, divided into 3 distinct groups for the analysis of the results: underweight (age=20.40±1.18, BMI=17.81±0.93), normal weight (age=20.504±1.671, BMI =22.24±1.67) and overweight (age=22.44±2.24, BMI=28.01±2.74). 7 tests were used to evaluate the explosive strength of the lower body (Vertical Jump Test, Standing Long Jump Test, 3-Hop Test, The multiple 5 bounds test, 30s Lateral double leg hop test, 30s Continuous vertical jumps, Speed Test 10m). A number of 6 tests were used to evaluate the explosive strength of the upper body (Overhand ball throw, Shot put, Overhead Medicine Ball Throw-forward, Overhead Medicine Ball Throw-backward, Medicine ball chest throw, 30s Plyometric Push-Ups). Results. Univariate test results indicate F values associated with significant thresholds at the lower body level (P<0.05) for tests based on horizontal jumps (Standing Long Jump, 3-Hop Test and The multiple 5 bounds test), where underweight and normal weight have the better average scores. At the level of the upper body, the situation is changed (for Shot put and medicine balls throws), where the overweight have the best average values, followed by the normal weight, and the worst results are found for the underweight group (P<0.05). Only for the Overhand ball throw and 30s Plyometric Push-Ups, the superiority of the overweight is not statistically confirmed (P>0.05). Correlation calculation (Pearson values) indicates positive associations between body height and vertical and horizontal jumps (except for those repeated for 30s), but negative associations of BMI and body mass with jump-based tests. However, BMI and body mass are moderately, positively and significantly correlated with throw-based tests (P<0.05). Conclusions. We can state that the classification of students in different BMI categories generates differences in explosive strength values between the 3 studied groups. The comparisons indicate the superiority of underweight and normal weights over overweight in all lower body explosive strength tests. The comparisons indicate also the significant superiority of overweight in the medicine ball and shot put tests over normal and underweight. The obtained results cannot be generalized, due to the small size of the underweight and overweight samples. Further investigations on larger groups of university students being necessary.

“…Their description is presented in the Appendix, to allocate more space to the presentation of results and discussions. Additional information related to the tests applied in order to assess muscle strength is provided by the sources [46][47][48][49][50]. The large number of tests required assessment in two separate sessions/days (one for lower body strength, one for upper body strength), in groups of 15-20 students.…”

Explosive strength has a decisive role in the rapid execution of movements and in achieving sports performance. The purpose of the study is to identify the differences in the level of explosive force for the upper and lower body, depending on the involvement in curricular physical activities, leisure physical activities or physical efforts in various sports disciplines. The participants are students of the Faculty of Physical Education and Sport/bachelor’s degree: 147 men (age = 20.82 years old). The study was based on a transversal research, with the division of students into 3 distinct investigation groups (as an independent variable), according to sports majors: IS (individual sports), TSG (team sports games) and NA (non-athletes). 7 lower body explosive force evaluation tests and 6 upper body explosive force evaluation tests were applied. The use of ANOVA/Analysis of variance and the comparison on pairs of sports specializations indicate statistically significant differences for most of the tests, between the TSG and NA, respectively IS and NA groups, with the superiority of the athletes. No significant differences are reported between the TSG and IS groups, with 2 exceptions: in the 30s-Plyometric Push-Ups the IS group has significantly better values, respectively in the 30s-lateral hop for the TSG group (p ≤ 0.05). The results of our study are in line with the average performance values provided by other research in the field (although they are weaker than those of elite athletes). The superiority of the individual values of volleyball players and sprinters/Track and field for the power of the lower body, respectively of combat sports practitioners and practitioners of sports games—which use the muscle groups of the trunk and arms in training—for the power of the upper body is confirmed, so the specificity of the effort also influences the explosive force values.
